A California king size mattress is an excellent upgrade from a queen size bed. California kings provide you and your sleeping partner with 36 inches of personal space. That’s almost the same width as a twin mattress. Plus, Cal king beds give you four extra inches of legroom—perfect for taller couples who want more space to stretch out.

In our article, we review some of the best California king size mattress models on the market today. If you’re looking for the best mattress, a Cal king could be the right fit.

Watch Our Amerisleep AS3 Video Review

When I first came across the Amerisleep AS3, I was intrigued by the brand’s reputation for blending comfort and innovation. But I didn’t want to rely on claims alone—I took a deep dive.

After weeks of research, hands-on testing, and comparing notes with my team of sleep testers, I can confidently say that the Amerisleep AS3 stands out as one of the most well-balanced mattresses I’ve reviewed. It truly hits that sweet spot between cushioning and support, which isn’t easy to find, especially in a foam-based build.

My testers and I evaluated this mattress across different sleep positions, body types, and environmental conditions, and the results were remarkably consistent. Whether it was pressure relief for side sleepers or spine alignment for back sleepers, the AS3 delivered across the board.

What really impressed me, though, was its adaptability—offering comfort without compromising on support, and maintaining coolness even after hours of lying in bed. In a market flooded with options, it’s rare to find a mattress that feels genuinely engineered for everyday people like me and my team.

Exceptional Versatility Across Sleep Positions

After evaluating dozens of mattresses this year, what made the AS3 rise to the top of my list was its ability to cater to almost every sleep position. I tested it myself, and I had my team of testers with varied sleep habits try it as well. Some were side sleepers who often struggle with shoulder pressure, others were back or combo sleepers. Each one reported comfort without any sense of sinking or stiffness. From my personal analysis, the medium firmness is perfectly tuned—around a 6.5 to 7 on the firmness scale—making it a real crowd-pleaser.

Scientifically-Backed Cooling

One of the top complaints I see from readers is about overheating at night. So, I specifically tested the AS3 under warm room conditions to see how it performs. The Bio-Pur® foam, which I’ll explain in more detail below, includes an open-cell structure designed to promote airflow.

It’s not just marketing fluff—I actually measured a difference in retained heat compared to other memory foam beds. My team also tested it during warmer nights and found it consistently cooler than traditional foams. That’s a huge win if you tend to sleep hot like I do.

Sustainable and Safer Materials

What drew me in even further was Amerisleep’s sustainability angle. As someone who values safe, eco-conscious products in my home, I appreciated that the AS3 uses partially plant-based foam.

After researching its certifications and chemical profile, I confirmed it’s CertiPUR-US® certified—meaning it’s low in VOCs and free of harmful substances like ozone depleters or formaldehyde. It feels good knowing my mattress choice isn’t contributing to toxic indoor air quality, and my testers with sensitivities also reported no off-putting chemical odors.

When I first lay down on the Amerisleep AS3, the experience was immediate and distinct—it felt like a gentle embrace, soft and adaptive, yet without that sensation of sinking too deep. Over the course of several weeks, I rotated through various sleeping positions, and I had my team of sleep testers do the same.

Each of us came back with impressions that reinforced my initial reaction: this mattress delivers an impressively balanced feel. It’s plush enough to relieve pressure but supportive enough to keep your spine properly aligned.

For me personally, as someone who switches between sleeping on my back and side, I noticed that the Bio-Pur® foam gently conformed to my curves—especially around the shoulders and hips—without feeling like I was “trapped” in the mattress. I also appreciated that I didn’t feel like I had to fight the foam to turn over, which is often the case with traditional memory foam beds.

My side-sleeping testers, who are often the most sensitive to pressure buildup, gave the AS3 high marks. They felt cradled in just the right places. One tester with chronic shoulder tension said it was the first mattress in a long time where she didn’t wake up feeling sore in the mornings.

The zoned HIVE® transition layer seemed to do its job—offering more give where needed (like the shoulders and hips), and a bit more firmness through the lumbar region.

Back sleepers in my group appreciated how the mattress kept their spines aligned throughout the night. I paid close attention to this aspect during the tests, because back sleepers often need that perfect balance between cushion and core support. My testers consistently noted how their lower backs felt supported without any unnatural arching or sinking.

Even combination sleepers like me—those who shift from side to back to stomach—were impressed. The AS3’s responsiveness made transitions smooth. I personally found that it had a kind of intuitive give-and-take: as I adjusted my position, the mattress adjusted right along with me. No resistance, no awkward dip or delay in support.

As for stomach sleepers, this was the one group where feedback was more mixed. A few lighter-weight testers said they felt fine, but the heavier testers felt their hips sinking slightly too far, which could lead to lower back discomfort over time. I agree with their assessment—it’s not overly soft, but if you’re a strict stomach sleeper, you might prefer something firmer to keep the pelvis better elevated.

We also made it a point to test for motion isolation. I shared the mattress with my partner several nights in a row and was pleasantly surprised by how little motion I felt when she shifted or got up.

The all-foam construction, especially the top Bio-Pur® layer, absorbs movement really well. It’s the kind of mattress I’d recommend for couples who are light sleepers or have different sleep schedules.

I make it a priority to fully break down the construction of any mattress I review—not just for transparency but because the layers define how it feels and performs over time. The Amerisleep AS3 is a 12-inch mattress made entirely of foam, divided into three layers that each play a critical role.

  • Top Layer – 3″ Bio-Pur® Foam
    I researched this proprietary material extensively and found that it’s Amerisleep’s alternative to traditional memory foam—offering better airflow and a faster response time. When I laid on it, I noticed that it cradled my pressure points without the “stuck” feeling I’ve had with conventional memory foam. My testers also noted how comfortably it molded to their bodies without overheating.
  • Middle Layer – 2″ Affinity Foam with HIVE® Technology
    This is where the targeted support comes in. I actually mapped out the firmness zones and found that it gives more cushioning under the shoulders and hips, and firmer support under the lumbar and feet. That balance really supports spinal alignment—something I always test with side and back sleepers in my group.
  • Base Layer – 7″ Bio-Core® Support Foam
    This bottom layer gives the mattress its stability and long-term durability. I’ve tested beds that start off great but sag after just a few months. The AS3’s base feels solid and resilient, even after prolonged testing from multiple users. It passed the motion transfer and edge support tests well, especially for a foam mattress.

Pros:

  • All-Sleeper Versatility: I tested it across side, back, and combo sleeping styles—and it performed beautifully in each case thanks to its medium firmness and zoned support system.
  • Excellent Temperature Control: The breathable foam and cooling cover made a noticeable difference, especially for my testers who tend to overheat at night.
  • Eco-Friendly and Non-Toxic: I did a deep dive into the certifications, and the plant-based foam combined with CertiPUR-US® safety standards made me feel great about having this in my home.

Cons:

  • Too Soft for Dedicated Stomach Sleepers: In the tests, stomach sleepers felt their hips sink in slightly, which could lead to misalignment over time.
  • Low Bounce for Active Sleepers: While it’s responsive for a foam bed, the AS3 doesn’t offer the springiness of a hybrid or innerspring, which some people prefer.
  • Mild Off-Gassing: We did notice a faint smell during unboxing—normal for foam mattresses—but it dissipated within a day or two with proper ventilation.

Amerisleep AS3

Lying down on the Amerisleep AS3 mattress feels comfortable and supportive in various sleeping positions. Back sleepers experience proper spinal alignment and lumbar support, although those preferring firmer surfaces might opt for the AS2 model.

Watch Our Zoma Boost Video Review

After personally testing the Zoma Boost, I came away impressed with how well it blends cutting-edge materials and thoughtful construction to support a deep, restorative sleep. When I first unboxed it, I noticed the mattress quickly expanded to its full 15-inch height, signaling quality foam recovery and construction.

My team and I evaluated this mattress over several nights, testing various sleep positions and tracking how well it adapted to pressure points, body movement, and temperature shifts.

What stood out most was how balanced this mattress felt—not too firm, not too soft. It’s crafted to offer responsive support while maintaining a cool and comfortable surface throughout the night.

From its breathable, cooling cover to the combination of graphite-infused memory foam and adaptive coils, this mattress was clearly engineered with performance and comfort in mind. It’s especially well-suited to people who want pressure relief without the overly “sinking” feel of traditional memory foam.

I chose to feature the Zoma Boost after hours of comparing hybrid mattresses that cater to a wide range of sleep needs. What pushed this one to the top of my list wasn’t just the specs on paper—it was how consistently it delivered in real-world use across different sleep styles.

My testers included side sleepers, back sleepers, and even a couple who often shift positions throughout the night. All of them reported waking up with less stiffness and better alignment.

The mattress performed exceptionally well in categories that truly matter: pressure relief, temperature control, edge support, and motion isolation. It’s one of the few hybrids I’ve come across that manages to check nearly every box while still feeling plush and supportive.

The inclusion of graphite-infused foam showed a clear reduction in surface heat retention, making it a go-to pick for hot sleepers.

And from a value standpoint, it offers features that rival more expensive brands—something I always appreciate when recommending a mattress to readers who want long-term performance without breaking the bank.

Sleeping on the Zoma Boost felt like a perfectly calibrated mix of support and plushness. As someone who rotates between back and side sleeping, I found that the mattress adapted seamlessly to my body in either position. The top memory foam layers softly cradled my shoulders and hips, while the coil base delivered enough firmness to keep my spine aligned and reduce lower back tension.

What really impressed me was the temperature regulation. I tend to sleep hot, and with many memory foam mattresses, I wake up feeling sweaty. However the graphite infusion in the comfort layers noticeably kept the surface temperature cooler, even during warm nights.

One of my colleagues—who often sleeps on their stomach—also noted how the mattress didn’t compress too much under the chest or hips, which is a key indicator of good core support.

If you enjoy that gentle “hug” of memory foam but dislike sinking too deeply or feeling stuck, this mattress strikes a great balance. It responds quickly when you shift positions and offers just enough bounce to feel active without sacrificing pressure relief.

The Zoma Boost is built with a thoughtful combination of layers, each selected for a specific sleep function. As someone who pays close attention to mattress materials, I appreciated the synergy of these components working together.

At the base, you’ve got zoned pocketed coils that adapt to different parts of the body and provide edge-to-edge support. This design helps maintain spinal alignment, especially in heavier areas like the hips and shoulders.

Above that is a layer of Reactiv™ foam, which acts as a responsive buffer between the coils and memory foam. It delivers a slightly springy feel that makes shifting positions easy, so you never feel stuck.

On top, you get two layers of graphite-infused memory foam that are engineered for pressure relief and cooling. These layers contour nicely around the body, cushioning key areas while pulling heat away from the surface.

Everything is wrapped in a breathable, stretch-knit cover that promotes airflow and contributes to the cooling experience. All foams used are CertiPUR-US® certified, which gave me peace of mind knowing they’re free of harmful chemicals and low in VOCs.

Pros:

  • Outstanding Cooling Performance: The graphite-infused foam and breathable cover actively dissipate body heat, making it a great pick for hot sleepers or those living in warm climates.
  • Excellent Motion Isolation: The combination of memory foam and pocketed coils absorbs movement well—ideal for couples who don’t want to be disturbed by a restless partner.
  • Balanced Support: With zoned coils and a responsive foam transition layer, this mattress supports a variety of sleeping styles and body types.

Cons:

  • Not Ideal for Firm Mattress Lovers: If you’re someone who prefers a very firm or ultra-dense sleeping surface, this mattress might feel too plush.
  • Heavy and Bulky: At 15 inches tall, it’s quite thick and can be challenging to move or set up without help—especially in larger sizes.
  • No Natural or Organic Materials: While the mattress uses high-quality, certified-safe foams, eco-conscious shoppers looking for organic latex or wool may want to look elsewhere.

Zoma Boost

To date, the Zoma Boost is my favorite mattress that I’ve tested. Lying down on the Zoma Boost mattress in different sleeping positions offers varying experiences. For back sleepers, it provides good support and alignment, though some who like a super firm mattress may find it slightly soft.

Watch Our Vaya Hybrid Video Review

As someone who’s been reviewing mattresses professionally for years, I’ve learned to spot the difference between flashy marketing and genuinely thoughtful design. After thorough research and hands-on testing, I can say the Vaya Hybrid has truly earned its place in my top recommendations. I was drawn to its promise of balanced comfort and support without an outrageous price tag—and it delivers.

The California King size in particular caught my attention for its generous dimensions and how well it accommodates couples or taller individuals. But a large mattress isn’t automatically a better one.

That’s why I spent weeks sleeping on the Vaya Hybrid, rotating through different sleeping positions, and asking my team of testers to do the same. Together, we assessed everything from pressure relief to motion isolation and breathability.

What I discovered is that the Vaya Hybrid is a sleeper’s dream when it comes to all-around value. It offers a plush, pillow-like surface with breathable comfort layers, a supportive coil core, and excellent edge reinforcement—qualities that are surprisingly hard to find in a mattress under $1,000. The medium firmness makes it versatile across sleeping styles, while the advanced materials keep the mattress cool and responsive.

Choosing this mattress wasn’t just about specs—it was about real-life performance. I’ve tested dozens of hybrids, and what stood out to me about the Vaya Hybrid was how well it performed across all the categories that matter to most sleepers. Comfort, pressure relief, cooling, durability, and motion isolation—it checked every box.

  • What made me seriously consider it for this category was how consistent it was.
  • It’s rare to find a mattress that performs just as well for side sleepers as it does for stomach sleepers.
  • During testing, my team and I rotated sleeping styles every night.
  • Whether it was me lying on my side with sensitive shoulder pressure points or one of my testers sprawled on their stomach, the Vaya Hybrid provided even support and cradling.

And then there’s the price.

  • The California King size offers significant space and comfort, yet Vaya keeps it under $1,500—almost unheard of for a hybrid that uses individually pocketed coils and custom foam layers.
  • That’s why I chose this mattress. It didn’t just meet expectations—it exceeded them in a way that I believe most sleepers will genuinely appreciate.

Lying down on the Vaya Hybrid felt like a perfect middle ground between plush and supportive—what I’d call “comfortably neutral.” I tested it first by lying flat on my back, and the foam layers gently cradled my lower back while the coils below provided solid support. I didn’t feel like I was sinking in too deep, which is often a problem with memory foam beds.

When I switched to my side, I noticed how well the foam conformed around my shoulders and hips—two major pressure points for side sleepers like myself. There was no pinching or numbness, even after staying in that position for a while.

My testers had similar reactions. One of my colleagues who sleeps exclusively on her stomach said the mattress gave her the pushback she needs to keep her hips from dipping, which can cause lower back pain. Another tester who tosses and turns reported that it was easy to change positions without feeling stuck.

But what I loved most was the motion isolation combined with the bounce. You get a bit of spring from the coils—just enough for ease of movement—but without the disruptive ripple effect that typically comes from traditional innerspring designs. The mattress responded instantly to my movements, which made it ideal for combination sleepers or couples sharing the bed.

As someone who scrutinizes mattress construction closely, I was impressed by how intelligently the Vaya Hybrid is built. Each layer contributes meaningfully to comfort, support, and longevity, rather than being filler or a gimmick.

Starting from the bottom, it features a high-density support foam base layer. This gives the mattress its foundational structure and ensures it doesn’t sag over time. It’s firm and resilient, exactly what you need to support a hybrid build.

Above that sits a pocketed coil system made up of hundreds of individually wrapped coils. These aren’t your old-school Bonnell coils—each spring moves independently, which helps contour to your body and minimizes motion transfer. During the durability test, the coils held up excellently under pressure and maintained their bounce and structure even after repeated use.

On top of the coils is Vaya’s proprietary pressure-relieving foam. Unlike traditional memory foam that can feel slow or hot, this one responds quickly and remains breathable. It conforms just enough to relieve pressure points but never feels like quicksand. That’s especially important for combination sleepers who move around during the night.

Then there’s the 2-inch Euro top layer, quilted with cotton. This is the part that cradles you when you first lie down. It feels plush and inviting, with excellent airflow thanks to the breathable cotton. I noticed it helped regulate temperature significantly better than thicker synthetic tops.

Wrapping it all up is a lightweight, stretchy cover that moves with you. This outer fabric is soft to the touch, moisture-wicking, and flexible enough to allow the foam and coils underneath to perform their jobs effectively.

Pros

  • Balanced Support and Pressure Relief: Offers just the right amount of contouring and firmness to accommodate all sleep styles without sacrificing spinal alignment.
  • Sleeps Cool All Night: Between the breathable cotton top, open-cell foam, and airy coil core, the mattress regulates temperature better than many pricier competitors.
  • Exceptional Edge Support: Reinforced sides make it ideal for couples or anyone who uses the entire surface of the bed.

Cons

  • Moderate Motion Transfer: While decent for a hybrid, you might feel your partner’s movements if you’re a particularly light sleeper.
  • Not Ultra-Firm: Stomach sleepers who need very firm support may find it a tad soft.
  • No Luxury Cooling Tech: It stays cool, but lacks specialized cooling gels or covers seen in more expensive models.

Vaya Hybrid

Lying down on the 14 inch tall Vaya Hybrid mattress offers a comfortable experience across various sleeping positions. Its foam and coil construction cater to back, side, stomach, and combination sleepers.

Watch Our Helix Midnight Luxe Video Review

After months of researching, analyzing specifications, and running hands-on tests with my trusted team of mattress reviewers, I confidently found the Helix Midnight Luxe to be one of the most well-balanced luxury options available—especially for those seeking extra space and personalized support. From the moment I unboxed it to the night I slept on it, the entire experience felt thoughtfully crafted.

What stood out to me immediately was how the mattress walked a fine line between plush softness and robust structural support. I analyzed its hybrid construction—blending memory foam and individually wrapped coils—which allowed the mattress to gently cradle the body while still maintaining excellent spinal alignment.

As someone who frequently rotates sleeping positions throughout the night, I appreciated how this mattress adapted to every shift without resistance. My team of testers, ranging from side sleepers to restless combo sleepers, consistently praised the Helix Midnight Luxe for its comfort, responsiveness, and impressive motion isolation.

In all, the Helix Midnight Luxe isn’t just a mattress—it’s an engineered sleep experience. Every layer, from the breathable cover down to the reinforced coils, has been carefully developed to support better sleep. If you value long-term support, zoned ergonomics, and premium materials, this mattress genuinely holds its own.

When I began testing options in the oversized and premium category, I kept a few non-negotiable criteria in mind: comfort, temperature control, durability, and partner-friendliness. The Helix Midnight Luxe checked off everyone—and here’s why:

  1. Outstanding Pressure Relief for Side and Combo Sleepers

One of my personal priorities during testing is to make sure the mattress doesn’t just feel good—but that it performs over time. When I lay on the Helix Midnight Luxe, I noticed how it eased tension around my shoulders and hips without making me sink too deeply. My team of side sleepers gave it top marks for pressure relief, noting that it helped eliminate morning stiffness.

This mattress uses memory foam strategically, so it contours where needed, while the supportive coils underneath keep the spine from dipping. Whether you’re sleeping on your side, back, or flopping in between (like me), this mattress adjusts with grace.

  1. Reliable Cooling Technology

I’m a warm sleeper—so trust me when I say I’m hyper-sensitive to heat retention. After researching the GlacioTex Cooling cover and comparing it to the TENCEL version, I opted to test both. While both were breathable, the GlacioTex version was a standout in the heat dissipation tests.

We measured temperature changes throughout the night, and the Luxe outperformed most hybrids we’ve reviewed, maintaining a comfortable, neutral sleep surface. For hot climates or sweaty sleepers, this feature is a major win.

  1. Excellent Edge Support for the Entire Sleep Surface

Edge support doesn’t get enough credit—until you’re sharing a bed and realize you need every last inch of sleeping space. When I tested the Helix Midnight Luxe, I made sure to roll, sit, and even lie directly on the edge. It held firm.

Thanks to the reinforced coils around the perimeter, you won’t feel like you’re slipping off the edge. My testers echoed the same sentiment: you get 100% of the mattress’s width—no sagging, no sink.

  1. Low Motion Transfer Makes It Couple-Friendly

I always test motion isolation with a partner—and a water glass. Helix Midnight Luxe passed both tests. Even when my partner tossed and turned, I barely felt a ripple. The multiple layers of dense foam on top of the coil system do an incredible job of absorbing energy before it can travel across the bed.

For light sleepers or couples with different sleep schedules (like many of my testers), this mattress is a dream. You won’t be jolted awake by someone else getting in or out of bed.

Testing the Helix Midnight Luxe for the first time was a moment of clarity—it was that instantly comforting. You sink in just enough to feel cradled, but you also feel like the mattress is lifting you, not letting you fall too deep. It’s that sweet spot I’m always chasing during testing.

For me, the side-sleeping experience was the highlight. My shoulders felt weightless, and I woke up with no stiffness—something I hadn’t experienced in weeks. Back sleeping was equally impressive. The lumbar support kept my hips aligned with my spine, and I noticed far less tossing and turning throughout the night.

Combo sleepers in my testing group reported high satisfaction, especially those who change positions often. The mattress responded quickly and didn’t create dips that made shifting uncomfortable.

Real User Reviews That Resonated with My Experience:

  • “My hips feel supported no matter what position I’m sleeping, and my back pain is almost non-existent. Spinal alignment felt (and looked) great, too.”
    Laura
  • “The Midnight Luxe has excellent edge support. No matter how close I roll toward the side of the bed, there’s no sign of sagging.”
    Michael

One thing I always emphasize to readers is: never to underestimate the power of good design. After analyzing the construction layer by layer, it was clear that Helix didn’t cut corners with the Midnight Luxe.

Cover Options: TENCEL or GlacioTex

Right off the bat, you get a choice: the default TENCEL cover or the GlacioTex Cooling cover. I tried both. The TENCEL version is ultra-soft and breathable, made from eco-friendly lyocell. It’s great for mild sleepers or those in temperate climates.

The GlacioTex, though, is a game-changer if you tend to overheat. It has a silky feel and actively draws heat away from your body. During the trials, this material cooled down 20% faster than standard covers under identical testing conditions.

Quilted Pillow Top Layer

Directly beneath the cover is a plush quilted pillow top, giving the mattress an instant feeling of luxury. This layer isn’t just for aesthetics—it adds cushioning for initial pressure relief. It’s soft to the touch but still taut enough not to feel saggy over time.

My testers commented on how this layer made the mattress feel “hotel-grade” the moment they lay down.

Memory Foam & Comfort Layers

Then come the true comfort materials: Helix’s Memory Plus Foam and high-density support foam. I loved how this memory foam wasn’t the “stuck” type—it responded quickly but still gave a classic hugging feel.

Next is the layer of copper gel-infused foam, which enhances both pressure relief and thermal conductivity. The copper addition isn’t just marketing—it genuinely helps disperse heat, which I confirmed during the lab-based evaluations.

Zoned Coil System for Targeted Support

This is the heart of the mattress: the zoned coil system. After dissecting the mattress and testing each zone’s firmness, I found the coils firmer under the lumbar region and softer near the shoulders. This helped maintain a straight spine while still offering cushion for pressure-prone areas.

The edge coils are double-reinforced, giving the mattress a stable perimeter—another feature that boosted the ratings significantly.

Base Layer: DuraDense Foam

At the bottom, a firm DuraDense foam base locks everything in place. It’s not something you feel directly while sleeping, but it adds years of life to the mattress and prevents sagging. I’ve seen too many hybrids fail in this department—this one doesn’t.

Pros:

  • Exceptional pressure relief and ergonomic support for side and combo sleepers
  • Outstanding cooling options—especially the GlacioTex cover
  • Zoned coils and foam layers offer near-zero motion transfer for couples

Cons:

  • The price point may be higher than entry-level hybrids
  • May feel too plush for those who prefer a firmer sleep surface
  • Cooling cover is a paid upgrade, not included by default

Helix Midnight Luxe

The Helix Midnight Luxe Mattress, overall, is a fantastic mattress. This mattress offers exceptional comfort and support for both side and back sleepers. Its plush pillow top and memory foam layers cushion pressure points, ensuring a gentle cradle without sinking sensation.

Mattress Highlights:
  • Dual-coil design with responsive, supportive feel.
  • Euro pillow top adds pressure relief and luxury.
  • Eco-friendly materials and no off-gassing.
Recommended For:
  • Back and stomach sleepers wanting firm support.
  • Shoppers preferring a traditional innerspring feel.
  • People with back pain needing zoned lumbar support.

When I began researching the most luxurious and reliable options for those who want a truly spacious and supportive sleep surface, the Saatva Classic stood out immediately.

My team of testers and I spent weeks analyzing and sleeping on this mattress, and I can confidently say it’s one of the most impressively engineered mattresses I’ve tested to date. With its thoughtful hybrid innerspring design, eco-conscious materials, and robust support system, this mattress doesn’t just look high-end—it performs like it too.

The first thing that grabbed my attention during testing was how well the Saatva Classic adapts to different sleeping styles without compromising on comfort or support.

Whether I was sprawled on my back, curled on my side, or laying on my stomach, the mattress offered the right mix of plushness and pushback, thanks in part to its unique dual-coil construction and targeted lumbar support.

But what makes the Saatva Classic especially appealing for those who need extra space is how well it scales up in a California king-size. Even with two people in bed, there was more than enough room to spread out without feeling like you’re disturbing your partner.

That, combined with the responsive bounce, excellent edge support, and cooling airflow, makes it a top-tier choice for anyone who values premium comfort and space to stretch.

After putting over two dozen mattresses through the rigorous testing process, I kept circling back to the Saatva Classic for a few key reasons.

First, the lumbar support system.

  • As someone who occasionally struggles with lower back stiffness, I was truly impressed by the difference the patented Lumbar Zone® technology made.
  • It’s not a gimmick—it genuinely supports the lower back better than most mattresses I’ve tested.

Second, versatility.

  • I’ve reviewed countless beds that claim to work for “all sleepers,” but the Saatva Classic actually lives up to that promise.
  • My testers included side sleepers, back sleepers, and even a couple of restless combo sleepers, and across the board, everyone felt supported and comfortable. That’s incredibly rare.

And finally, I picked this mattress because Saatva delivers the whole package.

  • We’re talking about a mattress that’s handcrafted in the U.S., shipped with free white glove delivery, and backed by a 365-night sleep trial and lifetime warranty.
  • I love it when a brand backs its product with that kind of confidence—it says a lot about the quality.
  • Plus, it’s made without fiberglass, which is a big plus for safety-conscious shoppers like me.

If I had to describe the feel of the Saatva Classic in one word, it would be balanced. When I first lay down on it, I felt that instant plushness from the pillow top, but almost immediately, the underlying support layers engaged to keep my body aligned.

I tested the Luxury Firm version, which sits right in the middle of the firmness scale, and it truly walks the line between comfort and support. It’s not too soft, not too firm—just right for most people.

For me, this mattress felt particularly great as a back-and-side sleeper. I felt the cushioning ease my shoulders and hips while the lumbar support kept my spine in neutral alignment.

Some of my fellow testers preferred the Plush Soft version, especially lighter-weight side sleepers who wanted deeper pressure relief. And the Firm model got thumbs up from the stomach sleeper, who needed a flatter surface to avoid sinking in at the hips.

Changing positions was also a breeze. The dual-coil system gives the mattress just the right amount of bounce to help you move freely without waking your partner. Plus, the breathable cotton and coil layers kept the bed temperature neutral even after hours of sleeping. I never felt hot or clammy, which is something I often deal with on dense foam beds.

During my hands-on inspection, I broke down the Saatva Classic layer by layer to understand how each component contributes to the sleep experience.

  • Starting from the top, there’s a plush 3-inch Euro pillow top wrapped in organic cotton. It feels luxurious to the touch, and I appreciated that the cotton is treated with Guardin®, a botanical antimicrobial finish that helps keep things fresh and clean.
  • Underneath the pillow top lies a layer of high-density memory foam that’s CertiPUR-US® certified. This layer isn’t overly thick, so you don’t get that deep, sinking feeling—just enough contouring to hug your pressure points without swallowing you.
  • In the center third of the bed, a Lumbar Zone® Active Spinal Wire is added to further reinforce support beneath your lower back. I could really feel this element at work during sleep—it subtly supports you without feeling stiff.
  • The real star, though, is the dual-coil system. The top layer features individually wrapped 14.5-gauge recycled steel coils that adapt to your body and isolate motion.
  • Beneath that is a second layer of tempered 13-gauge open steel coils for long-term durability and robust support.
  • Around the edges, high-density foam rails reinforce the perimeter, giving you excellent edge support. In a California King size, that extra stability makes the entire bed usable, even the very edge.

Pros

  • Exceptional lumbar support thanks to the patented Lumbar Zone® and Spinal Wire design—great for those with back pain.
  • Outstanding edge support, especially important in a larger size like California King where people often use the full mattress width.
  • Responsive, cool, and easy to move on, making it ideal for combination sleepers and hot sleepers alike.

Cons

  • Motion isolation could be better than all-foam models—some movement is still noticeable when a partner shifts.
  • May be too tall for some—with two height options (11.5″ and 14.5″), the thicker model can require deep pocket sheets or a lower bed frame.
  • Not a budget mattress—while it offers excellent value, it’s priced higher than simpler bed-in-a-box options.

Saatva Classic

The Saatva Classic mattress impressed me across various sleep positions during testing. As a side sleeper, I felt well-cradled without sinking excessively at the hips and shoulders, while stomach and back sleepers will appreciate the ample support provided.

Watch Our Nolah Evolution Video Review

After diving deep into mattress testing, a few models impressed me quite like the Nolah Evolution 15. From the moment I unboxed it with my testing team, I could tell this mattress was engineered with both comfort and performance in mind.

Over several weeks, I personally slept on the Evolution 15, tracked temperature regulation, measured motion transfer, and analyzed how well it supported various body types and sleeping positions.

I evaluated this mattress not just by lying on it—but by breaking down every component layer by layer, cross-referencing customer feedback, and even comparing it with top competitors in the hybrid space.

What stood out to me most during the testing was how well-rounded the Evolution 15 is. It’s not just about luxury—it’s about smart engineering. You’re getting a mattress that supports the body where it needs it most, adapts to movement without sinking too much, and keeps you cool on warm nights.

My team of testers included side sleepers, back sleepers, and even a few with shoulder and back pain. Across the board, this mattress scored highly in pressure relief and comfort consistency. It’s rare to find a bed that accommodates such a wide range of sleepers—and still feels as luxurious and balanced as this one does.

  1. It Sleeps Exceptionally Cool

Cooling performance is one of the biggest pain points for people upgrading to a larger mattress, especially with thick foam layers that often trap heat. What I found through testing is that the Evolution 15 genuinely excels in this area. It uses a combination of ArcticTex™ fibers, a heat-escape gusset, and breathable coil systems to move heat away from the body.

I used a thermal camera during overnight testing and observed lower temperature retention compared to many other luxury hybrids in its class. For hot sleepers or those living in warmer climates, this is a game-changer.

  1. Zoning That Makes a Difference

Not all zoned support systems are equal. The Nolah Evolution’s HDMax™ Tri-Zone™ coils impressed me with how they adjust to different areas of the body. I noticed firmer support under the lumbar and hips—where you need it to stay aligned—and gentler give around the shoulders and knees.

When I tested it across different body weights and sleep styles, that adaptive zoning created a sense of tailored comfort that was consistent and effective. It’s not just marketing fluff—it really works.

  1. Comfort Options for Every Type of Sleeper

Another reason this mattress made my list is its versatility. You can choose between three firmness levels: Plush, Luxury Firm, and Firm. I tested all three, and the Luxury Firm stood out as the most universally appealing. It cradled pressure points while maintaining spinal alignment.

That said, for stomach sleepers or heavier individuals, the Firm version offers a more supportive feel, while the Plush is incredibly cozy for side sleepers. The availability of these options means this mattress isn’t just one-size-fits-all—it’s truly customizable to your preferences.

  1. Durability Backed by a Lifetime Warranty

I don’t just consider how a mattress feels today—I also evaluate how it’s going to hold up years down the line. What gives me confidence in recommending the Evolution 15 is both the robust construction and the warranty backing it up.

The use of high-density foams, reinforced edge support, and resilient coils adds to its longevity. Add in the lifetime warranty and 120-night sleep trial, and it’s clear Nolah believes in the quality of this mattress just as much as I do.

The first thing I noticed when lying on the Nolah Evolution 15 was the balance—it feels plush, yet not too soft. My body gently sank into the top layer, but I didn’t feel stuck. It’s a mattress that invites you to relax deeply but still supports you enough to move freely.

Side sleeping felt like floating, with ample cushioning for my shoulders and hips. When I switched to my back, I could feel the tri-zoned support lifting my lumbar spine and holding my posture in a neutral alignment.

One of my testers, a combination sleeper who often switches between her back and side, said it was one of the few mattresses that never left her with sore shoulders in the morning.

Another tester, who typically overheats at night, said this was the first hybrid he’s tried where he didn’t have to kick off the covers midway through the night. And honestly, I had the same experience—it stayed cool and breathable through every test.

Customer Reviews:

“This mattress completely transformed my sleep. The cooling layers are incredible—I no longer wake up sweaty, even during summer. Plus, I barely feel my partner moving next to me.”

“I’m a side sleeper with chronic hip pain, and this mattress offers just the right pressure relief without being too soft. The Luxury Firm version is my sweet spot—it hugs without sinking.”

Quilted Euro Topper

Right at the top, the mattress features a plush Euro topper made with soft organic cotton and ArcticTex™ fibers. During my testing, I could feel the breathability immediately. The fabric doesn’t just add softness—it wicks away moisture and helps keep your body at a stable temperature. The quilted texture adds that extra touch of luxury, giving the mattress a hotel-bed feel from the first night.

AirFoamICE™ Comfort Layer

This layer is exclusive to Nolah and combines the pressure-relieving benefits of memory foam with the cooling responsiveness of open-cell foam. I found this layer helped reduce peak pressure points at the shoulders and hips during side-sleep tests. What’s different from traditional memory foam is how fast it bounces back—it doesn’t trap you, and it’s much cooler.

Supportive Transition Foam

This mid-layer acts as a buffer between the plush comfort layers and the coil base. It’s firmer, offering a little pushback to keep the sleeper from sinking in too far. I found it plays a key role in supporting heavier sleepers and maintaining proper alignment throughout the night.

HDMax™ Tri-Zone™ Coils

This is the heart of the mattress. These coils are not only zoned for tailored support, but they’re also individually wrapped to reduce motion transfer. During the tests, I dropped weights on one side of the bed and measured vibration on the other—minimal movement carried over. The reinforced perimeter coils added strong edge support, which is crucial in a mattress this wide and tall.

Recycled Plant Fiber Base

The bottom layer adds stability to the entire structure and enhances the mattress’s environmental profile. It’s made with plant-based materials and helps with breathability from the base up.

Pros:

  • Exceptional cooling features for a comfortable sleep temperature.​
  • The zoned support system offers targeted pressure relief and spinal alignment.​
  • High-quality, eco-friendly materials ensure durability and sustainability.​

Cons:

  • The 15-inch profile may be too tall for some bed frames.​
  • Premium pricing might not fit all budgets.​
  • Limited availability in physical retail stores for in-person testing.

Nolah Evolution

Lying down on the Nolah Evolution mattress in different sleeping positions offers a versatile and supportive experience. As a side sleeper, the zoned AirFoam layer provided effective pressure relief for hips and shoulders, while the Tri-Zone Support Coils offered targeted spinal support.

Watch Our Amerisleep Organica Mattress Video Review

After months of hands-on testing, analysis, and digging into the specs, I can confidently say this mattress stands out as a remarkable option for those who value eco-conscious craftsmanship without compromising on comfort or performance.

I personally researched every material used in its design, tested it in real-world sleeping conditions with my team of testers, and closely monitored how it handled pressure, temperature regulation, motion transfer, and edge support.

The mattress features a medium feel that adapts beautifully to most sleeping styles—especially side and combination sleepers. It strikes a rare balance between luxurious softness and supportive resilience.

The hybrid construction—blending organic cotton, natural wool, Talalay latex, and individually pocketed coils—brings together breathable comfort and sturdy structure. What impressed me most was the absence of off-gassing, the rapid full expansion, and the responsiveness that made moving around on it feel effortless.

From its durable build to its sustainable origins, every inch of this mattress is carefully curated. Whether you’re sleeping solo or sharing with a partner, it delivers cool, clean, and customized rest night after night.

I didn’t arrive at this choice lightly—I tested dozens of options with my team before narrowing in on this model.

  • What ultimately led me to pick this mattress was the rare fusion of three key attributes: sustainable sourcing, exceptional comfort across sleep positions, and high-end durability. While many mattresses boast about being organic or eco-friendly, few follow through to this level of execution.
  • I was particularly drawn to its use of GOTS-certified organic cotton and OEKO-TEX-certified wool—these aren’t just buzzwords. I took the time to verify the certifications and even compared the material integrity under magnification.
  • Then came the responsiveness of the Talalay latex layer, which my team and I evaluated with pressure tests, motion transfer simulations, and edge compression benchmarks.
  • Every feature that Amerisleep advertised, I put to the test—from breathability and fire resistance to edge support and cooling.
  • I picked this mattress not just because it passed all metrics but because it performed beautifully in everyday use—quiet, cool, comfortable, and crafted with genuine intention.

Lying down on this mattress for the first time felt like a sigh of relief. I sank in just enough to feel cradled, but never once did I feel trapped. I sleep mostly on my side, and this mattress gave me that perfect blend of softness at the hips and shoulders with uplifting support through my spine. That Talalay latex layer springs back quickly, which made changing positions during the night smooth and natural.

During testing, my team and I rotated through all sleep positions. Back sleepers experienced consistent lumbar support, while stomach sleepers noted only minor hip sinkage—something a firm topper could easily remedy. For combination sleepers, it truly shined. The responsiveness we felt during the weight-drop tests translated into a seamless experience in real-time movement.

The cooling factor was another pleasant surprise. I tend to overheat at night, but thanks to the breathable cotton cover, the natural wool, and the airflow from the coils, I stayed dry and cool even during long, uninterrupted stretches of sleep.

Overall, this mattress felt grounded, buoyant, and balanced. It’s plush where you want it and firm where you need it—and that’s not easy to achieve.

When I broke the mattress down layer by layer, it became clear that Amerisleep wasn’t cutting any corners.

The outer cover is made with soft, breathable GOTS-certified organic cotton. I ran my fingers across the fabric and immediately felt the difference in quality. It’s luxuriously soft but still durable, with extra-long staple fibers woven into a resilient, skin-friendly surface that wicks away moisture faster than any synthetic I’ve handled.

Just beneath the cover is a layer of organic New Zealand wool—plush, springy, and naturally insulating. I tested its elasticity myself and found it rebounded faster than synthetic blends. It also adds fire resistance without using harsh chemicals or fiberglass. That matters to me—both for personal safety and peace of mind.

At the core, you’ll find natural Talalay latex. It’s buoyant, breathable, and responsive. When I tested it for pressure relief, it outperformed many polyfoams we’ve reviewed. Finally, the pocketed coil base adds zoned support and edge reinforcement. I could literally feel the sturdier coils along the perimeter when sitting or lying near the edge.

All these materials work harmoniously to create a breathable, toxin-free, and adaptive sleep surface that feels just as good as it performs.

Pros

  • Eco-friendly construction: Made from GOTS-certified organic cotton, OEKO-TEX wool, and Talalay latex with no off-gassing or toxic chemicals.
  • Excellent responsiveness: Latex and coils allow effortless movement and ideal support across multiple sleep positions.
  • Cool and breathable: Natural materials and airflow design regulate temperature effectively for hot sleepers.

Cons

  • Edge support could be firmer: Slight dipping near the perimeter when sitting on the edge, especially for heavier individuals.
  • Not ideal for strict stomach sleepers: Slight hip sinkage may cause alignment issues without a firmer topper.
  • Medium feel may not suit all: Those seeking ultra-soft or ultra-firm beds may find the middle-ground firmness too neutral.

Amerisleep Organica

Laying down on the Amerisleep Organica mattress provided a unique and refreshing sleeping experience, thanks to its all-natural latex construction. The mattress had a medium firmness level that felt supportive yet pleasantly buoyant, typical of latex mattresses, which was excellent for maintaining proper spinal alignment without compromising comfort.

Watch Our Amerisleep AS6 Black Series Video Review

After extensively testing dozens of high-end mattresses, the one that stood out most in this category was the Amerisleep AS6. I approached this review not just as a writer, but as a meticulous researcher and hands-on tester—because when you’re investing in a luxury sleep setup, you deserve insight that goes deeper than just marketing language.

I wanted to find a mattress that offered pressure relief, cooling performance, support, and long-term durability all in one package—and after weeks of evaluation, the AS6 delivered in every category that matters.

This mattress was designed for deep, restorative rest, and my team of testers and I were genuinely impressed by how well it performed across sleeping positions and user types.

Whether we were side sleeping, back sleeping, or switching between positions during the night, the AS6 maintained an impressive balance of plush comfort and ergonomic support. But what really surprised me were the high-tech materials—like plant-based memory foam and titanium-infused layers—that actually made a difference in real-world testing.

I’ve reviewed many beds over the years, but this one quickly became a favorite. It’s not just that it looks impressive with its 15-inch profile and premium detailing—it feels like a luxury mattress should: be cool, responsive, and indulgent, without compromising support. If you want the feeling of sleeping on a mattress that seems to “know” your body, the AS6 is worth serious consideration.

When my team and I set out to find a mattress that combined luxury with performance, we weren’t just looking for the softest or most expensive option—we were looking for something that could genuinely enhance sleep quality. And through hands-on testing, I found that the Amerisleep AS6 checked every box.

I picked this mattress after carefully analyzing how it performed in multiple core areas: pressure relief, spinal alignment, responsiveness, edge support, and motion isolation.

What sealed the deal was its rare ability to balance these features without leaning too hard into any one extreme. Too many plush mattresses feel like you’re sinking into a beanbag, and too many supportive ones feel like you’re sleeping on a board. The AS6 finds a middle ground that feels customized—like it adapts to you.

During testing, I paid close attention to movement across the mattress, partner disturbance, cooling performance, and how well the materials held up after repeated use. The AS6 didn’t just pass my evaluations—it impressed me. From the plant-based BioPur® foam to the CryoCool cover and the PrecisionCoil support system, every element felt intentional and effective.

I picked the AS6 because it’s rare to find a mattress that feels plush without compromising support, responsive without being bouncy, and cooling without being stiff. It’s a technical achievement—and one that translates into better sleep night after night.

From the moment I lay down on the AS6, I could tell it was designed for pressure relief without sacrificing structure. It has a plush, almost cloudlike top layer, but the support kicks in exactly where you need it. This dual sensation—being both cradled and lifted—is hard to find, and my team and I kept coming back to it during testing.

The feel is highly adaptable. As a side sleeper, I immediately noticed how my shoulders and hips sank in just enough to relieve pressure without misaligning my spine.

When I switched to my back, I felt a gentle support under my lower back that kept everything aligned, and as I tested it on my stomach, the firmer coils beneath prevented any sinking at the hips that would otherwise cause back pain.

It’s also incredibly responsive. I never felt stuck, even after the foam had fully molded my body. That BioPur® foam recovers quickly, allowing me to change positions without resistance. It’s the kind of surface that feels luxurious but not lazy—like it’s working with your body, not against it.

Another thing I want to highlight is the temperature regulation. From the TitanAir™ foam to the Arctic Wave bands and the CryoCool™ cover, the entire mattress stays noticeably cooler than other premium memory foam beds we’ve tested. It maintains a stable, comfortable temperature even after hours of sleep—which is a game-changer for hot sleepers or couples.

In short, the AS6 feels like the best of both worlds: plush yet supportive, cozy yet cool, responsive yet pressure-relieving. It delivers a sleep experience that feels elevated without being over-engineered.

The construction of the AS6 reads like a checklist of every modern mattress innovation I look for in a high-performance bed. And after physically dissecting each layer during the testing process, I can confirm: that every material here serves a distinct and valuable purpose.

  • At its core, the AS6 uses PrecisionCoils—individually wrapped coils that move independently to support your body exactly where it needs it. These coils help with motion isolation and edge support while adapting to your weight and sleeping style. Around these coils is a sturdy foam encasement that enhances edge integrity, which my testers and I really appreciated when sitting or lying near the perimeter.
  • Above the coils lies an Affinity foam transition layer. This is where Amerisleep starts showing its engineering chops. This layer helps distribute weight evenly while preventing that unpleasant feeling of sinking too quickly. It acts as a bridge between the firm coils and the soft upper layers.
  • Then there’s the comfort layer, made from BioPur® memory foam—a plant-based foam that replaces some of the petrochemicals used in traditional memory foam. What impressed me most here is how it feels both plush and responsive. It cradles your body without swallowing you whole.
  • Just above that is the TitanAir™ layer—an advanced, titanium-infused foam that adds a slight bounce and active temperature control. And finally, it’s all topped with a CryoCool™ cover that instantly feels cool to the touch and keeps heat from building up.

In total, the AS6 has a 15-inch profile—significantly taller than average—which gives it a rich, hotel-like presence in the bedroom.

Pros:

  • Unmatched Pressure Relief: The BioPur® comfort layer adapts to the body’s curves, especially beneficial for side sleepers and those with joint pain.
  • Exceptional Cooling: With titanium-infused foam, CryoCool™ cover, and strategic Arctic Wave cooling bands, it stays cool even on warm nights.
  • Versatile Support: Works well across all sleep positions thanks to its balanced construction and three firmness options.

Cons:

  • May be too soft for heavier stomach sleepers: Even the firm version may not offer enough lift for those over 230 lbs in this position.
  • Premium price point: While I believe it’s worth the investment, the cost may be out of budget for some buyers looking for an affordable hybrid.
  • Limited bounce: If you prefer a springy, latex-like feel, this mattress may feel a bit too dampened in responsiveness for your taste.

Amerisleep AS6 Black Series

The AS6’s triple-cooling system isn’t just marketing fluff, as it’s genuinely impressive. The combination of the CryoCool cover, TitanAir layer, and ArcticWave cooling bands creates what might be the most effective temperature regulation I’ve seen in a foam hybrid mattress. For hot sleepers tired of waking up sweating, this could be a game-changer.

Watch Our Plushbeds Signature Bliss Video Review

When I received the Signature Bliss mattress from PlushBeds, I approached the testing with the same rigor and curiosity I bring to every high-quality mattress I review. What immediately set this mattress apart for me wasn’t just its luxurious materials—but the way every component worked in harmony to create a well-balanced, eco-conscious sleep experience.

This wasn’t your typical “greenwashed” product; it was an authentically organic option backed by global certifications like GOTS and GOLS. From the breathable cotton knit cover to the buoyant Arpico latex and sturdy pocketed coils, everything about this mattress exudes thoughtful craftsmanship.

As someone who has reviewed countless mattresses, I found this one to be a standout for a variety of reasons. It offers the rare blend of a plush feel with responsive support, which made it a hit among my team of testers with different sleep styles. Over several weeks, I personally rotated between sleeping on my side, back, and stomach to observe how it adapted to each position.

I also performed stress tests—dropping calibrated weights, checking for bounce-back speed, and even testing edge integrity while sitting and lying on the perimeter. What I found was a mattress that didn’t just promise luxury—it delivered it, consistently and across all critical performance areas.

After months of research and dozens of hands-on mattress evaluations, I can confidently say that the Signature Bliss earned its place at the top of my list for a few compelling reasons.

First, it checked every box when it came to organic certifications.

  • I dug deep into its supply chain and manufacturing practices and was genuinely impressed by how transparent and eco-responsible the brand is.
  • In a world full of synthetic blends and chemically treated foams, PlushBeds’ use of certified organic wool, cotton, and natural latex made this mattress a breath of fresh air—literally and figuratively.

But I didn’t choose it on certifications alone. I picked it because it consistently scored high in every major category that matters: pressure relief, edge support, temperature regulation, and motion isolation.

During testing, it performed so well that even the pickiest members of my testing team—those who usually complain about sagging edges or sleeping hot—found little to criticize.

This is the kind of mattress that adapts well to a wide range of needs.

  • Whether you’re a hot sleeper, a combination sleeper, or someone seeking hypoallergenic comfort without sacrificing performance, this mattress ticks every box. It’s rare to find such a well-rounded model that manages to be both luxurious and practical.

Lying down on the Signature Bliss for the first time felt like sinking into a cloud with a solid base—soft on top but supportive underneath. As I spent more time testing it, that initial impression held strong.

Whether I was on my back, side, or stomach, the mattress cradled my pressure points without letting me sink too far in. The Arpico latex provided that signature buoyant feel—kind of like sleeping on a gentle springboard rather than a slow-sinking marshmallow.

One of my testers, Sarah—a lifelong side sleeper with shoulder sensitivity—reported that her shoulder pain had significantly reduced after a few nights. “I didn’t have to shift positions as often, which is rare for me,” she said. The plush comfort layer provided enough give to relieve pressure on her shoulders and hips without compromising spinal alignment.

For back sleepers, the Signature Bliss does a fantastic job of supporting the natural curvature of the spine. I personally found the medium version perfect for combination sleeping. It offered just enough contouring when I was on my side but kept my spine aligned when I rolled onto my back. The responsiveness of the latex made shifting positions feel effortless—ideal for anyone who changes positions throughout the night.

Stomach sleepers tend to need a firmer surface to prevent the hips from dipping too low. One of the testers, Julian—who sleeps mostly on his stomach—said he felt “well-supported in the hips and chest” and didn’t wake up with the usual lower back tightness he gets from softer mattresses. He tested the medium-firm option, which seems better suited for stomach-dominant sleepers.

Another tester, Marcus, who sleeps hot and tends to toss and turn, commented, “I stayed cool the whole night, and I barely noticed my partner moving at all.” That’s thanks to both the breathable organic materials and the mattress’s strong motion isolation. Even when my partner got up in the middle of the night, I remained undisturbed.

In short, no matter your preferred sleeping position, the Signature Bliss adapts without losing its structural integrity. It strikes a near-perfect balance between comfort, responsiveness, and support—making it a solid choice for solo sleepers and couples alike.

What truly impressed me during the unboxing and setup process was the construction of this mattress. Unlike many of the one-piece foam beds I’ve tested in the past, this one arrived in two separate boxes, allowing me to inspect and appreciate its internal components piece by piece.

At the very top is a GOTS-certified organic cotton cover, featuring a circular knit design that isn’t just soft to the touch—it actively encourages airflow and moisture-wicking. It’s like the athletic wear of mattress covers—light, breathable, and designed for performance.

Underneath the cover is a layer of organic British wool, which serves multiple roles: natural flame retardant, moisture manager, and thermal regulator. This isn’t some thin, decorative layer—it’s substantial and functional.

Then comes the heart of the mattress: 3 inches of GOLS-certified Arpico latex. This layer is dense and highly responsive, instantly conforming to your body and bouncing back the moment you shift positions.

Finally, at the base, you’ll find a robust layer of individually wrapped coils. These provide zoned support while also boosting breathability and motion isolation. Importantly, the entire construction is glue-free, relying on a smart zip system that allows access without the use of harmful adhesives—something my testers with chemical sensitivities deeply appreciated.

Pros:

  • Exceptional material quality: Certified organic cotton, wool, and latex—free of toxins and designed for long-term durability.
  • Outstanding responsiveness and support: Adapts instantly to position changes, making it ideal for combo sleepers and couples.
  • Superior motion isolation and edge support: Perfect for light sleepers or anyone who shares their bed.

Cons:

  • Premium price point: Not budget-friendly, though justified by quality and longevity.
  • Slightly involved setup: Arrives in two boxes, requiring assembly (though manageable).
  • Medium firmness may not suit all stomach sleepers: Firmer option might be better for strict stomach sleepers.

After testing the Signature Bliss mattress in many different ways, I can tell you that this is one of the best mattresses I’ve ever tried. The natural materials, like the organic cotton cover and latex layer, work together like a well-practiced team to help you get great sleep.

Watch Our AS5 Hybrid Video Review

After years of testing dozens of mattresses across all sizes and styles, I can confidently say that the Amerisleep AS5 Hybrid stands out as a truly luxurious and thoughtfully engineered option. When my team and I first received this mattress for review, I had high expectations based on Amerisleep’s reputation—and I wasn’t disappointed.

As a certified sleep coach and a mom juggling long days and even longer nights, I need a bed that works as hard as I do. From the moment I unboxed the AS5 Hybrid and laid down for the first time, I felt an immediate sense of plush support and cooling comfort that signaled this mattress was something special.

Throughout my weeks of hands-on testing—evaluating edge support, cooling, motion isolation, and how it accommodates different sleeping positions—I discovered that this mattress excels in areas where others often fall short.

Whether you’re looking for pressure relief around the hips and shoulders, reliable edge-to-edge stability, or cooling features to combat night sweats, the AS5 Hybrid checks all the boxes. It’s particularly ideal for side sleepers or anyone who craves that “sleeping-on-a-cloud” feel without sacrificing back support.

When narrowing down my top mattress picks, especially in a spacious size like California King, I knew I needed something that offered more than just surface-level comfort. I wanted a mattress that combined high-end performance with health-forward materials and lasting durability. That’s why the AS5 Hybrid caught my attention—and ultimately earned its spot on my list.

I picked the AS5 Hybrid not only because of its plush comfort (which side sleepers will adore) but also because of its unmatched balance between softness and responsiveness. During testing, I was especially impressed by how it cradled my body without making me feel stuck.

My testers and I ran it through rigorous evaluations—using pressure maps, movement simulations, and multi-night sleep trials—and the AS5 Hybrid consistently delivered in performance. The motion isolation is top-tier, and the cooling technology genuinely kept me comfortable all night, even during hotter evenings.

What really sealed the deal for me, though, was the level of detail and science Amerisleep poured into this mattress. From the Refresh cover that’s designed to convert body heat into infrared energy to the advanced open-cell foam layers, every component felt purposeful and innovative.

If I had to describe the feel of the AS5 Hybrid in one word, it would be “luxurious.” But let me explain what that actually means from a practical standpoint.

Lying down on this mattress, you’re immediately greeted with a plush, inviting softness—almost like sinking into a thick, pillowy cloud that gently hugs your body. There’s an instant sense of comfort that almost tricks you into thinking this might be too soft.

But then, as your body settles into the layers, you start to feel the subtle but noticeable lift from the support system underneath. That’s where the magic happens. The Active Flex foam, paired with the pocketed coils, creates this rare combination of pressure relief and buoyancy. It’s soft enough to melt tension from your joints but structured enough to keep your spine aligned.

As a side sleeper, I experienced significant relief at my shoulders and hips—those typical pressure points that often flare up on firmer or lower-quality mattresses. I tend to rotate between fetal and three-quarter side positions throughout the night, and with the AS5 Hybrid, I never once felt that “numb arm” sensation or the need to constantly readjust.

Even though this mattress falls on the softer end of the spectrum (I’d rate it around a 3 out of 10 in firmness), I never felt like I was bottoming out or that my lower back was dipping too far. This balance makes it feel soft without being sloppy, which is honestly rare in ultra-plush beds.

Another standout quality is the responsiveness. Some memory foam beds can feel like quicksand, making it hard to move or reposition. That’s not the case here. The coil layer adds a light bounce that helps you transition between sleep positions effortlessly. It gives the bed a more dynamic, “alive” feel compared to all-foam models.

That said, this plush feel may not be ideal for everyone. During the testing phase, heavier back and stomach sleepers on my team noted a bit more sinkage around the hips than ideal.

It’s not that the support failed, but the ultra-soft top layers didn’t offer the same level of pushback they were used to. For sleepers over 230 pounds, especially those who favor stomach sleeping, this could potentially lead to alignment issues over time.

But for lightweight to average-weight side sleepers—or anyone who just craves a soft, responsive surface with a touch of luxury—this bed feels phenomenal. It’s the kind of mattress you look forward to diving into after a long day. Think boutique hotel comfort, but with better materials and tailored support.

As someone who’s spent years dissecting mattress construction, I can say the AS5 Hybrid is one of the most thoughtfully built mattresses I’ve tested. Here’s a deeper look into what it’s made of:

  • Refresh Cooling Cover: The first thing you’ll notice is the cool-to-the-touch cover. Made with proprietary materials that convert body heat into far infrared energy, this layer actively helps with circulation and keeps the surface feeling cool and breathable—even after hours of lying on it.
  • Bio-Pur® Foam: This is Amerisleep’s answer to traditional memory foam, and it outperforms in nearly every category. I loved how breathable and responsive it was. Unlike dense foam that traps heat and limits movement, the Bio-Pur® foam kept air flowing while molding gently to my body’s contours.
  • Active Flex Transition Foam: This layer is what gives the AS5 Hybrid its “plush but not sluggish” character. It instantly responds when I change positions, eliminating that stuck-in-the-mud feeling and offering a buoyant, floating sensation.
  • Zoned Pocketed Coils: Beneath the foam layers, a support system of individually wrapped coils delivers bouncy, responsive support that adjusts to different pressure zones. During testing, I especially appreciated the reinforced coils along the edges—they gave the mattress superior edge support and prevented sagging.
  • Support Base Foam: Finally, at the base is a high-density foam layer that helps stabilize the entire structure. It’s what ensures this mattress can hold up for years without losing shape or support.

Pros:

  • Exceptional Pressure Relief: Ideal for side sleepers who need extra cushion around the shoulders and hips.
  • Cooling Cover & Breathable Foam: Stayed cool and comfortable throughout the night, even during heatwaves.
  • Fantastic Motion Isolation: Perfect for couples—movements on one side of the bed didn’t transfer to the other.

Cons:

  • Too Soft for Stomach Sleepers: Hips may sink too far, throwing off spinal alignment.
  • Not Ideal for Heavyweight Sleepers: Those over 230 lbs might need firmer support to avoid sagging.
  • Premium Price Point: It’s a higher-end investment, which might not suit every budget.

Amerisleep AS5 Hybrid

Lying down on the AS5 Hybrid mattress in different sleeping positions offers a luxurious experience, especially for side sleepers. Its soft, contouring layers effectively cradle hips and shoulders, eliminating pressure points and promoting pain-free sleep.

When I began my search for the most spacious, luxurious mattress that could handle the needs of both solo sleepers and couples alike, one name kept surfacing: the Westin Heavenly Bed. Known for its presence in upscale hotel rooms across the globe, this mattress has become almost synonymous with premium sleep. I had high expectations going into this review—and I wasn’t disappointed.

The Westin Heavenly Bed is an innerspring-style hybrid mattress that balances hotel-grade luxury with home comfort. From the moment it arrived—fully expanded via white-glove delivery—it was clear this wasn’t just another bed-in-a-box.

I dove into a rigorous testing process with my team, examining everything from edge support and motion isolation to cooling ability, spinal alignment, and durability. After weeks of real-world sleep trials and technical assessments, I found the Heavenly Bed to be a true standout for those seeking a plush, cloud-like feel that still supports healthy posture.

Whether you’re a side sleeper who needs relief at the shoulders, a couple that moves around at night, or someone looking to bring that five-star hotel experience home, this mattress delivers in nearly every category.

It’s Not Just About Comfort—It’s About Consistency, Luxury, and Real-World Use

As someone who reviews mattresses for a living, I’ve tested hundreds of beds—but few have the legacy or reputation of the Westin Heavenly Bed.

What drew me to this mattress wasn’t just its plush surface or the buzz around its hotel heritage—it was the consistency in quality that I had experienced myself during hotel stays over the years.

I remembered waking up refreshed, pain-free, and with the unmistakable “wow” of a luxury night’s sleep. That’s rare—and I wanted to find out if the at-home version could live up to that memory.

From the moment the Heavenly Bed arrived (via white-glove delivery, no less), I knew I was dealing with something different. No compressed foam, no waiting hours for expansion—this was a fully formed, hotel-standard bed, and it showed in the details.

My testing wasn’t casual either. I brought in my team of testers, used calibrated weights to test motion transfer, ran thermal imaging tests for cooling, and even analyzed responsiveness using pressure sensors and manual transition tracking.

It performed well across all metrics.

What ultimately convinced me to include the Heavenly Bed among my top recommendations was how it performed across all those metrics. It wasn’t just soft and cozy—it was structurally sound, supportive at the edges, quick to respond to movement, and impressively breathable. That kind of well-rounded excellence is rare.

Another major factor? Durability.

The commercial-grade construction Westin uses is built for hotel-level wear and tear—which means when you bring it home, it’s likely to last even longer under regular use. And because it doesn’t require a platform bed (a proper box spring is recommended), it fits more traditional bedroom setups, which is a bonus for many shoppers who aren’t ready to overhaul their entire bed frame system.

Simply put, the Westin Heavenly Bed earned its place on my list not just because of how it feels, but because of how it performs over time—and how much real-world data I was able to gather to back that up.

Testing the Westin Heavenly Bed felt like checking into a five-star hotel and never checking out. From the moment I lay down, I could feel the plush comfort layers hugging my pressure points, especially around the shoulders and hips. It was that instantly soothing sensation you’d expect from a high-end hotel bed—inviting, cocoon-like, and indulgent.

But it never crossed into overly soft territory. There’s a thoughtful balance at play here. The upper layers cradle you in a gentle embrace, but the coils underneath provide a level of firmness and responsiveness that keeps your body aligned and supported.

The support system really shines when you shift positions. For side sleepers, the contouring is outstanding—soft enough to cushion the shoulders and hips, but firm enough to prevent that “sunken-in” feeling. It eases tension in all the right areas, helping you stay comfortable through the night without the need to constantly adjust. For back sleepers like me, the lumbar area stays nicely supported. I didn’t experience any dipping or pressure around my lower back, which is usually the first red flag for me on overly plush mattresses.

And even stomach sleepers, while they might lean toward something a touch firmer overall, will still find that the robust coil system keeps the midsection lifted, helping to avoid that awkward sway in the spine.

The overall feel is best described as cloud-like with structure. It’s plush without being floppy, and responsive without being bouncy. You get that luxurious initial sink that melts away surface tension, followed by a balanced, contouring support that holds you gently but firmly.

There’s a clear sense of quality in how the layers transition—you don’t feel any abrupt shifts or hard spots, just a consistent, elevated comfort that really does live up to the “Heavenly” name.

Whether you’re a restless sleeper or someone who stays in one position all night, the Westin Heavenly Bed adapts in a way that feels effortless. It delivers that rare combination of hotel luxury and ergonomic support—something that not many mattresses manage to get just right.

I always start my mattress evaluations by peeling back the layers—literally and figuratively—and with the Westin Heavenly Bed, I discovered a thoughtful construction built for long-lasting comfort. This isn’t a bed that just feels good at first touch—it’s engineered to maintain that comfort night after night.

Here’s a breakdown of what’s inside:

  • Support Core: Individually Wrapped Coils
    The foundation of the Heavenly Bed is a commercial-grade innerspring unit with individually wrapped coils. During testing, I was struck by how well these coils performed not just in support, but in motion isolation and airflow. Each coil moves independently, which helps prevent motion transfer between sleep partners—one of the reasons it scored so highly in my motion tests. These coils also allow for natural ventilation, which plays a big part in the mattress’s excellent cooling performance.
  • Comfort Layers: Gel-Infused Foam & Transition Foam
    Above the coils sit several layers of high-density foam, including a gel-infused comfort layer. I found this combo particularly effective at relieving pressure while avoiding that “stuck in the mud” feeling you sometimes get with memory foam beds. During side-sleeping tests, the foam cradled my shoulders and hips just enough to ease pressure points without throwing my spine out of alignment. And thanks to the gel infusion, the surface stayed noticeably cooler—even after several hours of use.
  • Top Layer: Deeply Tufted Pillow Top with Fenice Plush Fabric
    The top of the mattress is what most people fall in love with first. It’s a plush, pillow-top surface with tufting designed to lock layers in place and provide instant softness. I’ve tested a lot of pillow tops, and many lose their loft or shift over time. That wasn’t the case here. Even after repeated use, the surface maintained its shape and cushioning power. I also appreciated that the tufting wasn’t just decorative—it actually helped prevent the dreaded bunching or ridge effect you sometimes see with lesser-quality pillow tops.
  • Silver Fiber Infusion: Clean Sleep Technology
    Perhaps one of the most interesting materials used in this mattress is the invisible silver fiber technology. These fibers are infused throughout the surface layers to help resist bacterial buildup and maintain freshness. This isn’t just a gimmick—it’s a practical addition that aligns with the demands of hotel use, where hygiene is a top priority. Bringing that feature into the home space makes a lot of sense, especially for those who want long-term cleanliness without frequent deep cleans.

At 13.25 inches tall, the Westin Heavenly Bed strikes a nice balance between luxury and practicality. It’s thick enough to include meaningful comfort layers but still fits standard fitted sheets. When I made the bed after testing, even deep-pocket sheets fit snugly and stayed in place—no slipping, no bunching.

Pros

  • Hotel-Level Comfort at Home: Feels just like sleeping in a luxury suite.
  • Outstanding Edge Support: Great for couples and people who sit on the edge of the bed.
  • Cool and Clean Sleep: Gel-infused foam and silver fibers help with temperature and hygiene.

Cons

  • No Sleep Trial: You’ll need to visit a Westin Hotel to test it out before buying.
  • Firmness Options Are Limited: Currently offered only in a medium feel.
  • Box Spring Requirement: You’ll need a proper foundation to maintain warranty coverage.

After extensive testing and careful evaluation of every aspect of this mattress, I can understand why the Westin Heavenly Bed has maintained its reputation for over two decades as one of the most sought-after hotel mattresses.

After spending weeks researching and testing numerous mattresses alongside my team of testers, I discovered a standout choice that checked every major box for comfort, support, and performance. What caught my attention was not just the affordability, but the comprehensive design that caters to diverse sleep needs.

The mattress I selected arrived compressed in a manageable box and expanded beautifully with little to no off-gassing—a big plus right from the start. As a sleep coach and someone who genuinely values restorative rest, I know how essential the right mattress is to holistic health.

I approached this review with the same curiosity and scrutiny I would for my own home. Through hands-on testing, pressure mapping, temperature regulation checks, and edge stability evaluations, I assessed every angle of this mattress.

The result? A model that truly delivers—especially in the California King size—for individuals, couples, and budget-conscious shoppers seeking luxurious comfort without compromise.

When I first began analyzing options, I focused on a few key factors: affordability, quality materials, pressure relief, and motion isolation.

  • What made this mattress stand out wasn’t just its reputation or price—it was how it performed across all the objective tests and subjective experiences.
  • I picked it because it consistently excelled in categories that matter most to people like me who juggle busy lives, care about sleep health, and want long-term comfort.
  • My team and I were especially impressed by the responsiveness of the Reactiv™ foam, which helped us shift positions effortlessly during sleep.
  • For couples, it proved to be a reliable choice with excellent motion isolation.
  • And as someone who overheats easily, I paid close attention to breathability.
  • The gel-infused memory foam and ventilated cover actively worked to keep my body temperature cool throughout the night.
  • All in all, I chose this mattress because it represents a rare balance of performance, value, and thoughtful construction that fits a wide range of sleepers.

Right from my first night, the mattress delivered a supportive yet cushioned feel that seemed to adapt naturally to my body. I’m a combination sleeper—rotating between my back, side, and occasionally stomach—and I was surprised by how well the mattress accommodated each position.

On my side, I felt the memory foam gently contour around my shoulders and hips, easing tension in those high-pressure areas. When I rolled onto my back, the support remained consistent, keeping my spine aligned and my lower back relaxed.

What stood out most was how balanced the firmness felt—it hit that sweet spot between soft and supportive, right around a 6 out of 10 on the firmness scale. Even my team of testers, with a variety of sleep styles and body types, echoed similar sentiments.

I appreciated the subtle bounce from the Reactiv™ layer, which made movement feel effortless. It’s the kind of mattress that meets you where you are—soft where you want it, firm where you need it.

From the base up, this mattress is crafted with a meticulous combination of performance foams designed for lasting support and luxurious comfort. When I unwrapped it, I took time to inspect each layer and pay attention to how they interacted.

  • The bottom foundation is a dense Support+ foam layer that provides the structure and prevents sagging over time.
  • Above that lies the Reactiv™ transition foam—a springy, responsive material that ensures you never feel trapped in the bed. I could feel the difference immediately during the motion tests; it bounced back quickly and made repositioning feel seamless.
  • The comfort layer features gel-infused memory foam, which cradles your pressure points while promoting airflow. That’s where most of the “ahh” feeling comes from when you lie down.
  • Topping it all is the breathable AirCloth cover—stretchy, cool to the touch, and effective at wicking away heat. Each component has a purpose, and together, they make the mattress greater than the sum of its parts.

Pros:

  • Impressive Cooling Features: The gel-infused memory foam and breathable cover helped me stay cool all night—perfect for hot sleepers like myself.
  • Great for All Sleep Positions: My team and I agreed this mattress adapts well to side, back, and stomach sleeping without causing pressure buildup.
  • Exceptional Motion Isolation: Even with my partner tossing beside me, I barely felt a thing thanks to the absorbent all-foam design.

Cons:

  • Not Ideal for Heavier Sleepers Over 250 lbs: While I found it supportive, heavier individuals might need a thicker or hybrid model for better reinforcement.
  • Lower Profile at 10 Inches: Some people may prefer the feel or look of a taller mattress, especially in larger room settings like with a California King.
  • No Advanced Cooling Tech: While the gel and breathable cover do a good job, it lacks some of the high-end cooling innovations seen in premium models.

Why Choose a California King Mattress?

A California king size mattress is 72 inches wide by 84 inches long. Compared to a standard king size, a California king is longer and narrower, but it’s really not all that much of a size difference. California king beds don’t provide as much personal space as a king, but they make up for it with the four inches of extra length, especially if you or your sleep partner are over 6 feet tall.

If you are looking for a bed to accommodate two tall sleepers, you’ll enjoy the sleeping space a Cal king provides. These mattresses allow for 36 inches of room on either side of the bed, so you and your partner can enjoy your sleep area without feeling crowded. That said, if you aren’t taller and don’t need the extra legroom, you’ll probably prefer standard kings because they’re a hair wider.

How to Find the Best California King Mattress?

Before committing to a potential mattress, consider mattress type and firmness level. Mattress type looks at how a mattress responds to your weight, whether it feels bouncy, like an innerspring, or conforming, like memory foam. Firmness level refers to how the mattress surface feels—soft, medium, or firm.

These factors can help you find the best California king size mattress. Also, look at the price tag. You don’t want to go over your budget for a bed that may not have the long-lasting quality you need.

1. Mattress Type

Mattress type refers to the materials that make up a mattress. The four common mattress types include memory foam, latex, hybrid, and innerspring. If you like a bed with more bounce, an innerspring or hybrid are options you may enjoy. Memory foam and latex are excellent options if you’d rather have a mattress that didn’t bounce.

a. Memory Foam

Memory foam mattresses soften under heat and pressure, causing the foam to conform to your body’s natural curves and relieve pressure points. Unlike other mattress materials, memory foam provides superior comfort by soothing aching muscles. You’re less likely to wake up feeling sore because memory foam reduces pressure in heavier sections of your body, like the shoulders and hips.

Another benefit of choosing a memory foam mattress is motion isolation. Memory foam restricts motion from sleep movement. If you or your partner toss and turn at night, you’re less likely to wake up from their movements. Not only will you not feel your shifting sleep partner, but you won’t hear them either because memory foam produces little to no noise.

Traditional memory foam may feel too soft and cause the body to sink too deeply, trapping heat. You might wake up at night from overheating. To fix this, mattress manufacturers add cooling materials, like plant oils, gel, copper, and graphite. These materials better regulate temperature by pulling heat away and may prevent night sweats.

b. Latex

Latex shares similar properties with memory foam—both conform to your body for pressure relief and isolate motion. Unlike memory foam, latex doesn’t conform as closely, meaning latex conforms around your body. This rounded contouring doesn’t trap heat, but also cushions the body. Latex also has a responsive bounce because it’s more elastic than memory foam. You may find it easier to switch sleeping positions on a latex mattress because latex is firmer and more responsive than memory foam.

Latex is a natural material extracted from rubber trees. It’s resistant to dust mites, bacteria, and other allergens. If you or your partner experiences allergies, a latex mattress is an excellent choice.

c. Hybrid

If you and your partner are looking for a California king mattress with both the contour of memory foam and the bounce of an innerspring, a hybrid mattress could be the perfect option.

Hybrids contain 2 inches of memory foam or latex in the comfort layer and a coiled base. The foam layer conforms to your body for pressure relief, while the innerspring coils give a responsive bounce. You can enjoy pressure relief and a responsive surface with a hybrid.

Keep in mind, hybrids are more expensive than other types of mattresses because they contain so many materials. Using more materials also adds weight to the mattress. As a result, hybrids can be bulky and difficult to move.

d. Innerspring

Innerspring mattresses are bouncier than other mattress types. They contain steel coils in the support layer, topped with a thin foam or fiberfill comfort layer. Innersprings are naturally cool because the open structure inside the mattress allows more airflow. Their responsive surface makes it easier to climb in and out of bed.

However, innerspring mattresses have little to no motion isolation, meaning you’ll be able to feel your sleep partner’s movements (and vice versa). Also, innersprings provide the least amount of pressure relief because they have a thin comforter layer—not a good choice for side sleepers who need the most cushioning in the shoulders and hips. Memory foam or latex mattresses are better options if you’re looking for a bed with optimal pressure relief, and a hybrid is a great option if you want both pressure relief and bounce.

2. Firmness Level

When looking for a California king size mattress, it’s important to choose a bed based on firmness level, or how comfortable the mattress feels. Your ideal firmness level is based on your body type and preferred sleeping position.

a. Body Type

Lightweight sleepers who weigh less than 130 pounds will enjoy a soft to medium-soft mattress. This firmness can establish the most comfortable mattress for a lightweight sleeper because it allows their body to slightly sink for pressure relief. Firmer beds may feel too hard and create more pressure points.

In contrast, a plus-size sleeper who weighs more than 230 pounds won’t find a softer surface comfortable. Softer beds won’t provide enough support to a plus-size sleeper and may end up sagging. Instead, a comfortable mattress for plus-size sleepers is medium-firm to firm. This type of mattress offers plenty of comfort and support without sagging.

Best California King Size Mattress

Average sleepers weigh between 130 to 230 pounds and find the best comfort in medium to medium-firm mattresses. The medium feel is the perfect balance between comfort and support.

b. Sleeping Position

How you sleep can determine the right firmness level. For example, you probably won’t want to purchase a firm mattress if you sleep on your side. The surface may feel too hard, and you could experience pain or numbness in your shoulders.

  • Side Sleeping

Side sleepers place most of their weight on their shoulders and hips from lying on their side, causing pressure buildup in these areas—a softer surface relieves that pressure. A soft to medium mattress provides the soft, cushioning comfort side sleepers need for better sleep.

  • Stomach Sleeping

Stomach sleepers, on the other hand, need a firmer surface. Softer mattresses can increase the already-intense pressure placed on the spine when lying on the stomach. When stomach sleepers sink too deeply into the bed, they may experience back pain from excessive pressure. Instead, choose a medium-firm to firm mattress. This firmness lifts the chest and reduces pressure on the spine.

  • Back Sleeping

Back sleepers may feel less pressure because their bodies are resting in a neutral position. Medium to firm beds cradle their hips and give support to the lower back.

Firmer mattresses will also prevent the hips from sinking too deeply, which could misalign the spine.

  • Combination Sleeping

Medium to medium-firm mattresses are the best mattresses for combination sleepers. This surface supports your body, no matter which sleeping position you’re in, for consistent spinal alignment. Also, a Californian king is an excellent choice for combination sleepers because the large size gives you and your sleep partner more personal space. On a Cal king, you and your partner can comfortably switch sleeping positions without worrying about bumping into each other.

3. Price Tag

The cost for a California king size mattress ranges between $700 to $6,000. California king beds are one of the largest standard mattress sizes available and are more expensive than smaller mattress sizes. The price will also depend on the materials the mattress contains. For instance, natural materials, like latex, will cost more than memory foam. Latex foam is more durable than other materials.

Other Things to Consider

Before buying a California king mattress, you may want to consider your floor space and a potential mattress option’s warranty and sleep trial. You want to make sure you have room for a Cal king mattress, and ensure your new bed is covered at least ten years. Plus, it doesn’t hurt to have time to try out a mattress brand and determine it’s right for you.

1. Floor Space

The standard bedroom size is 11 feet by 12 feet, but if you want a California king size bed, you’re going to need a larger room. Master bedrooms at least 13 feet by 13 feet are best for a California king. This floor space gives plenty of room for a California king bed frame and extra room for lamps and nightstands.

A cramped bedroom can cause undue stress that could affect sleep quality. Avoid this by measuring your bedroom first to see if a California king will fit. If the bedroom is smaller than the recommended room size, a queen mattress might be a better fit. See our California king vs queen mattress guide.

2. Warranty and Sleep Trial

Mattresses are an investment; that’s why new mattresses come with some type of warranty. Warranties protect the customer from having to replace a new bed because of defects or sagging. Most mattress companies offer a standard 10-year warranty, though other brands may offer longer warranties, up to 20 years.

If you’re not sure if a particular mattress is right, see what kind of sleep trial is included with the mattress. At most, you may only get a few minutes to try out a new bed in a showroom, which isn’t enough time to find out if a potential mattress is right for you. However, many mattress companies offer sleep trials—a set amount of days to try out a new bed.

Online mattress companies offer longer sleep trials than in-store brands, about 90 to 120 nights. When you shop online, you’re unable to try the mattress before buying, so companies will give you more time to test the bed at home. In-store brands only offer 30-day return policies, which may not seem like much; but keep in mind, it may take the body a few weeks to adjust to a new sleep surface.

FAQs

Is there a bigger bed than a California king?

If a California king feels too small, then the Alaskan king might be the mattress for you. This giant mattress measures 108 inches by 108 inches—that’s a 9-foot by 9-foot bed! An Alaskan king size is an excellent option if you have a large family and regularly co-sleep with your children.

It’s not a standard size, so you may not see an Alaskan king in a showroom, but you can find this mattress size online. Be aware that you’ll have to have a bed frame and mattress foundation custom-made if you want an Alaskan king mattress.

Which size is better for couples? King or California king?

Both king and California king mattresses are excellent options for couples. Both provide lots of room to spread out without disturbing your sleep partner.
