Best Online Mattress: Reviews and Buyer’s Guide

During my research, I prioritized mattresses that cater to different sleeping styles, and the AS3 excelled here. Its medium firmness is ideal for side, back, and combination sleepers, offering the perfect balance of softness and support. This versatility made it a clear choice for people who share a bed or simply aren’t tied to one sleep position.

I also focused on temperature regulation—a critical factor for quality sleep. The AS3 impressed me with its dual approach to cooling: the Refresh Cooling Cover and the Bio-Pur® foam. Together, they promote airflow and reduce heat retention, making the mattress a standout for hot sleepers.

I carefully evaluated how each mattress handles pressure points and spinal alignment, and the AS3’s HIVE® technology was a key reason for its inclusion. This layer provides targeted support where it’s most needed, ensuring that shoulders and hips get extra cushioning while the back and legs remain properly supported.

Another deciding factor was the AS3’s commitment to sustainability. Its plant-based Bio-Pur® foam not only reduces environmental impact but also enhances durability. I found its materials and construction to be among the most eco-conscious and long-lasting on the market.

The top Bio-Pur® foam layer hugged my body just enough to feel cradled, but not trapped—a sensation I often dread with traditional memory foam. The medium firmness was spot-on, offering a unique blend of plush comfort and steady support.

The cooling effect of the Refresh Cooling Cover? It felt cool to the touch, even after lying still for a while, which made it ideal for hot sleepers like me. It’s rare to find a memory foam mattress that stays consistently cool, and the AS3 delivered on this front impressively.

For combination sleepers, transitioning between positions felt seamless. The mattress responded quickly to movement without any sinking or “stuck” feeling, which I appreciated after testing many foam mattresses that tend to lag in this area.

Customer reviews reflect my experience, emphasizing how the AS3 supports diverse needs. One user shared their skepticism about buying a mattress online but ended up surprised by its comfort and quality. “This will always be my go-to for all my beds,” they added, highlighting its American-made, non-toxic construction as a bonus.

Another review came from a side sleeper with a herniated disc, who praised its ability to support their back, neck, and hips: “It’s like Goldilocks and the Three Bears… truly just right!” This resonated with me, as the AS3’s zoned support system excels at relieving pressure without being overly soft or firm.

As a side sleeper, I felt a noticeable difference in how my shoulders and hips were cushioned. Pressure points that usually nagged me during the night were alleviated, allowing me to relax fully into the mattress. On my back, the AS3 provided excellent lumbar support, keeping my spine aligned without an overly firm or stiff feeling. It struck that elusive sweet spot where support feels natural, not forced.

The AS3 starts with a circular-knit Refresh Cooling Cover, a soft and breathable material designed to maintain skin temperature up to 7 degrees cooler over an eight-hour sleep period. Infused with special minerals, this cover converts body heat into far-infrared energy, promoting better blood circulation and muscle recovery while keeping the surface cool and refreshing.

Directly beneath the cover is the Bio-Pur® memory foam layer, a 2-inch plant-based foam that is more breathable and responsive than traditional memory foam. Its open-cell design promotes airflow, dissipates heat effectively, and prevents the “stuck” sensation often associated with foam mattresses. This layer provides excellent contouring, easing pressure points without compromising movement or support.

The 2-inch Affinity foam transition layer incorporates HIVE® technology, a zoned support system with hexagonal cutouts. These zones provide softer cushioning at pressure points like shoulders and hips while offering firmer support under the back and legs, ensuring proper spinal alignment and targeted pressure relief. This strategic design reduces tossing and turning, keeping sleepers comfortably aligned throughout the night.

At the foundation of the AS3 is the 8-inch Bio-Core® base layer, a durable, high-density foam that prevents sagging and soft spots over time. This layer reinforces the mattress structure, ensuring long-lasting support and stability while maintaining breathability to avoid heat retention.

Pros:

• Medium firmness suits all sleep positions.
• Excellent pressure relief with HIVE® technology.
• Bio-Pur® foam is cooling, responsive, and eco-friendly.
• Refresh Cooling Cover enhances temperature regulation.
• Durable construction with a 20-year warranty.

Cons:

• May feel too soft for those who prefer firm mattresses.
• Premium pricing compared to basic foam models.
• Limited edge support for those needing a firmer perimeter.

I was drawn to the Zoma Boost for several reasons:

• First and foremost, I was impressed by its innovative construction. The combination of zoned edge coil support and graphite-infused memory foam offers a unique blend of comfort and support. The graphite infusion is particularly appealing, as it helps to regulate temperature and keep sleepers cool throughout the night.
• Secondly, the Zoma Boost’s versatility is a major plus. Whether you’re a back, side, or stomach sleeper, this mattress can accommodate your preferred sleep position. Its medium firmness provides a balanced feel, offering adequate support without sacrificing comfort.
• Finally, the Zoma Boost’s performance is exceptional. It excels in key areas like motion isolation and edge support, making it a great choice for couples. The mattress also features a quick response time, which means you won’t feel stuck or trapped in the mattress.

After carefully considering these factors, I believe the Zoma Boost is a top-tier mattress that offers excellent value for the price.

Testing Experience

• I was first struck by the Zoma Boost’s smooth, cloud-like texture when I initially lay down on it. My shoulders and hips experience great pressure alleviation as the memory foam molds to my body. This is essential for a good night’s sleep as a side sleeper.
• The memory foam with graphite infusion is revolutionary. Even in the warmest summer months, it keeps me cozy and cool all night long. I no longer feel agitated or sweaty when I wake up.
• The motion isolation of the Zoma Boost is superb. I hardly notice my companion tossing and turning all night long. Their motions are absorbed by the mattress, keeping me undisturbed.
• The mattress’s edge support is also impressive. I can sit on the edge of the bed without feeling like I’m going to fall off. This is a significant advantage, especially for those who get in and out of bed frequently.

A Closer Look at Customer Feedback

• I’ve been amazed by the positive feedback from Zoma Boost customers. Russ from Jefferson City, MO, perfectly captured the mattress’s ability to promote a restful night’s sleep. As a fellow sleep enthusiast, I can wholeheartedly agree with his sentiments.
• Jess B. from Seattle, WA, highlighted the mattress’s impact on physical recovery. As an active individual, I understand the importance of a good night’s sleep for optimal performance. The Zoma Boost’s ability to alleviate muscle soreness and promote relaxation is a significant benefit.
• Phillip L. from Gonzales, Texas, succinctly summarized the Zoma Boost’s appeal: “Excellent bed. I highly recommend. Best night’s sleep in a long time.” I couldn’t have said it better myself.
• While most customers have had positive experiences, it’s important to note that Kathleen D. from El Cerrito, CA, found the mattress to be too warm. However, I did not encounter this issue.
• Gene J. from Madison, WI, praised the Zoma Boost’s edge support, pressure relief, and heat regulation. As someone who has tested numerous mattresses, I can confirm that the Zoma Boost is a top-tier product that offers exceptional value for its price.

To fully understand the Zoma Boost’s performance, it’s essential to delve into its construction.

Coil Support Layer: The foundation of the Zoma Boost is its Zoned Edge Coil Support System. This innovative system utilizes individually wrapped coils that offer targeted support to different body zones. These coils work independently, providing excellent motion isolation and preventing sagging over time.

Transition Layer: Above the coil support, you’ll find a layer of Reactiv™ Foam. This unique foam is designed to provide a balance of comfort and support. It quickly responds to pressure, providing a buoyant feel that helps to relieve pressure points and promote proper spinal alignment.

Comfort Layers: The top comfort layers of the Zoma Boost consist of dual layers of graphite-infused memory foam. Graphite is a highly conductive material that helps to dissipate heat, keeping you cool and comfortable throughout the night. The memory foam conforms to your body’s contours, providing customized support and pressure relief.

Cover: The mattress is encased in a soft, breathable cover that further enhances the cooling properties of the mattress. The cover is designed to wick away moisture and regulate temperature, ensuring a dry and comfortable sleep environment.

A Harmonious Blend The combination of these layers creates a mattress that is both supportive and comfortable. The coil support system provides a sturdy foundation, while the foam layers offer a luxurious and pressure-relieving sleep surface. The graphite-infused memory foam and cooling cover work together to keep you cool and comfortable, ensuring a restful night’s sleep.

Pros:

• Excellent Comfort and Support: The combination of memory foam and coil support provides a balance of softness and firmness.
• Superior Cooling Technology: Graphite-infused memory foam and a breathable cover keep you cool all night.
• Outstanding Motion Isolation: Minimal disturbance from a sleeping partner.
• Durable Construction: High-quality materials and robust design ensure long-lasting performance.
• Excellent Edge Support: Allows you to sit comfortably on the edge of the bed.

Cons:

• May Be Too Soft for Some: The medium-firm feel might not be suitable for those who prefer a firmer mattress.
• Initial Off-Gassing: Like many new mattresses, it may have a slight odor when first unboxed.

Simplicity Done Right

When I analyzed mattresses for this guide, I noticed many brands overcomplicate their designs with unnecessary layers and gimmicks. The Vaya Mattress, on the other hand, keeps it simple—just two well-engineered foam layers that deliver results. This approach isn’t just refreshing; it’s practical. Its focus on core performance makes it a standout option for anyone seeking comfort without overwhelming options.

Balanced Support for All Sleepers

One of the key reasons I included this mattress is its versatility. During my research, I found that the Vaya Mattress accommodates side, back, and stomach sleepers equally well. Its ability to align the spine and cushion pressure points ensures broad appeal, especially for households with different sleep styles.

Cooling That Works

Many mattresses promise cooling features but don’t always deliver. The Vaya Mattress impressed me because it integrates an open-cell foam design and a breathable cover to genuinely prevent overheating. My team of testers confirmed that it maintains a cool sleeping surface, even for those who tend to sleep warm.

Safety and Assurance

I also prioritized mattresses that are safe and reliable. The Vaya Mattress is CertiPUR-US® certified, which means it meets strict standards for material safety. Plus, its 10-year warranty and 100-night trial make it a risk-free investment, offering buyers the confidence they need when shopping online.

Immediate Comfort and Balanced Support

The first thing I noticed while lying down on the Vaya Mattress was the instant comfort of its medium firmness. It’s soft enough to cradle sensitive areas like the hips and shoulders, yet firm enough to maintain proper spinal alignment. As I shifted into my side-sleeping position, the foam contoured gently without excessive sinkage, offering a delicate balance between cushioning and support.

A reviewer described their experience as, “Perfect for relieving pressure on my side without making me feel stuck.” I found this sentiment to be spot-on, especially during extended periods of side sleeping.

Versatility Across Sleep Styles

Switching to my back and stomach, I appreciated how the mattress adapted seamlessly. It kept my spine aligned while evenly distributing my weight—a critical factor for avoiding stiffness. Combination sleepers will find the Vaya Mattress accommodating, as its responsiveness ensures smooth transitions between positions without feeling trapped.

One customer noted, “I’m a restless sleeper, and this mattress moves with me—it’s like it knows where I need support.” This aligns with my findings, as the Vaya Comfort Foam’s quick recovery time made it easy to shift without disrupting comfort.

Cooling and Breathability

I’m someone who tends to overheat during the night, but the Vaya Mattress excelled in keeping me cool. Its open-cell foam construction and breathable cover worked together to dissipate heat effectively. Even on warmer nights, the surface felt refreshingly cool to the touch.

As one user commented, “I used to wake up sweating, but now I sleep cooler and wake up refreshed.” This feedback mirrored my own experience with its excellent temperature regulation.

Edge Support and Motion Isolation

Testing edge support, I found minimal compression when sitting or lying near the edges, a rare feature for all-foam mattresses. The sturdy base foam provided consistent support even at the perimeter, making the mattress feel larger and more usable.

Regarding motion isolation, the Vaya performed impressively. Movements on one side of the bed barely registered on the other, ensuring a disturbance-free sleep environment.

This was echoed by a reviewer who said, “My partner tosses and turns, but I barely notice it anymore.”

The Vaya Mattress follows a minimalist design philosophy with a two-layer construction that prioritizes functionality over complexity.

1. Comfort Layer: Open-Cell Vaya Foam

The top layer consists of Vaya’s proprietary open-cell foam, engineered to balance comfort, cooling, and responsiveness.

• Adaptive Contouring: The foam adjusts to individual body shapes, providing tailored support and cushioning without excessive sinkage.
• Bounciness: Unlike traditional memory foam, this layer offers a responsive feel, ensuring smooth movement when changing sleeping positions.

2. Support Layer: Vaya Base Foam

Beneath the comfort layer lies a dense slab of Vaya Base Foam, designed for structural stability and targeted support.

3. Breathable Cover

The entire mattress is wrapped in a durable, breathable fabric cover.

• Cooling Touch: The cover enhances the open-cell foam’s cooling properties, wicking away heat and moisture.
• Long-Lasting Construction: The woven material is soft yet sturdy, complementing the mattress’s overall durability.

I analyzed numerous innerspring mattresses, and the Saatva Classic’s hybrid construction immediately caught my attention. 

1. Its dual-coil system, paired with a plush comfort layer, offers a balance of support and cushioning that caters to a wide range of sleeping positions. This thoughtful combination makes it versatile enough for couples or anyone with changing sleep preferences.

I found the incorporation of Lumbar Zone® Technology to be very noteworthy during my study. 

1. Among innerspring mattresses, this feature is uncommon as it offers focused lower-back support. This feature makes the Saatva Classic a clear candidate, given the significance of spinal alignment for general health.

Eco-friendly practices are becoming increasingly important in the mattress industry, and Saatva’s commitment to sustainability was a key factor in my decision. 

1. The use of organic cotton and other environmentally responsible materials impressed me. It’s not just about comfort but also creating a healthier and more sustainable sleep environment.

Another reason I included this mattress is Saatva’s customer-first approach. 

1. The 365-night sleep trial, lifetime warranty, and white glove delivery reflect confidence in the product that few other brands match. These policies offer peace of mind to buyers, which is essential for an online purchase.

For me, the Saatva Classic was a clear choice because it combines thoughtful design, eco-conscious materials, and user-friendly policies, making it a standout in the crowded market of online mattresses.

The immediate sensation was a perfect blend of softness and support:

1. The Euro pillow top greeted me with a plush, welcoming feel that cradled my pressure points—most noticeably around the shoulders and hips.
2. Yet, as I shifted positions, the underlying dual-coil system made its presence known, providing a steady, buoyant support that felt remarkably stable.

I appreciated how effortlessly the mattress adapted to my movements:

1. The Luxury Firm model, which I tested, struck a harmonious balance. It had just enough contouring to relieve pressure without feeling like I was sinking too deeply.
2. Even when lying flat on my stomach—a position that can sometimes strain the back—the mattress kept my spine well-aligned, thanks to its Lumbar Zone® support.

Movement across the surface felt smooth, almost effortless. 

1. While the pocketed coils did a great job of minimizing motion transfer, I noticed a faint, pleasant springiness—a subtle reminder of the mattress’s innerspring roots.

The top layer features a plush Euro pillow top, offering 3 inches of cushioning for immediate pressure relief.

1. Wrapped in a luxurious, organic cotton cover, it provides breathability and is treated with Guardin®, a botanical antimicrobial solution that keeps the surface fresh and hygienic.
2. Additionally, the cover incorporates Lumbar Zone® Quilting for enhanced lower-back support.
3. Saatva uses a natural plant-based thistle pulp as a flame retardant, avoiding fiberglass or chemical treatments, ensuring a safe and healthy sleep environment.

Beneath the pillow top lies a layer of CertiPUR-US® certified high-density memory foam, which adapts to the sleeper’s body for targeted pressure relief.

1. This eco-friendly foam is free from harmful chemicals and has low VOC emissions.
2. An innovative Lumbar Zone® Active Spinal Wire is embedded within this layer, offering additional support to maintain proper spinal alignment, especially in the lower back.

The core of the Saatva Classic features a sophisticated dual-coil construction:

1. Pocketed Coils:

884 individually wrapped coils (queen size), strategically firmer in the center to support weight distribution.

These 14.5-gauge recycled steel coils enhance contouring and reduce motion transfer, making the mattress ideal for couples.

1. Steel Open Coils:

416 tempered coils (queen size) form the durable base layer, preventing sagging over time.

The entire perimeter is reinforced with high-density foam rails, providing excellent edge stability. This design ensures the mattress remains supportive across its surface and makes getting in and out of bed easier—especially valuable for those with mobility challenges.

Many users praised its cooling properties, comfort, and motion isolation, which reinforced my decision to include it in this guide.

I noticed how the plush comfort layers in the soft and medium options cradled my hips and shoulders. The pressure relief was remarkable, making it ideal for side sleepers who often struggle with discomfort in these areas. The foam layers balanced softness without creating a sinking feeling, which can sometimes make it hard to move around.

Switching to my back, the medium and firm options shone. The zoned coil system provided support where I needed it most, particularly in the lumbar area. I felt my spine align naturally, and the added buoyancy from the coils prevented me from feeling stuck in one place.

For stomach sleeping, the firm option was the clear winner. It kept my midsection elevated, preventing that dreaded lower back strain that often plagues stomach sleepers. The firmer feel ensured my spine stayed neutral, and I didn’t wake up with any tension or aches.

The medium hardness choice was the ideal compromise for me as a combo sleeper. Changes between positions were smooth thanks to the supporting coils and responsive foam. I had no change in alignment or comfort whether I turned over on my side or rolled onto my back throughout the night.

Customer feedback often mirrors my observations, highlighting both the mattress’s strengths and areas where improvements might be made.

• Praise for Quality and Comfort:
  Linda M., a verified buyer, shares, “I’m loving my new mattress. I’m very happy with the quality. This is the second mattress I have bought from Brooklyn Bedding. The first one is in my aunt’s room and it still is great.” This echoes the durability and consistent performance I felt while testing the Aurora Luxe.
• Temperature Regulation Appreciated:
  Christa S. notes, “Super comfortable, soft, and not too warm to sleep in.” I couldn’t agree more; the cooling technology is undoubtedly one of the standout features here.
• Acknowledging Minor Issues:
  Robyn K., while mostly satisfied, highlights some minor drawbacks: “There are a couple of threads coming unstitched, one along the side and one along the top. And the top layer of cooling fabric is very slippery! But overall I’m very pleased with this mattress! Exceeding my expectations re: comfort!” These comments align with my own testing experience—while the cooling cover is effective, its slipperiness may take some getting used to.

The GlacioTexTM Cooling Cover, the uppermost layer, creates the ideal environment for a cool and cozy night’s sleep. This cover’s cutting-edge cooling fibers are intended to dissipate extra body heat and keep the temperature cool all night long. For people who sleep overheated or in warmer areas, the cover provides an immediate cool-to-the-touch sensation.

The initial comfort layer, composed of CopperFlexTM foam, is located beneath the cooling cover. In addition to giving your body responsive sculpting, this foam has a cooling infusion to stop heat accumulation. Because of its well-known antibacterial qualities, CopperFlexTM improves pressure relief while guaranteeing a hygienic and safe sleeping surface.

Together with the CopperFlexTM layer, the second comfort layer’s Supreme Response Comfort Foam creates a more flexible and supple feel. For people who like a medium-firm mattress or who sleep on their sides, this layer offers an additional degree of softness and pressure point alleviation.

A layer of gel swirl memory foam is included in the mattress to facilitate the transition from gentle comfort to stronger support. This layer lessens strain on delicate regions like the shoulders and hips and distributes weight evenly. You won’t overheat at night thanks to the gel infusion’s additional cooling benefits.

An 8-inch layer of individually encased Ascension® coils forms the mattress’s core. To promote appropriate spine alignment and lessen aches and pains, these coils are zoned to give specific support to certain body parts. You can sleep soundly even if your companion walks around since the enclosed construction also reduces motion transmission.

The final layer is a high-density foam base that provides a stable foundation for the mattress. This layer enhances the durability of the hybrid design, ensuring that the mattress maintains its shape and support over time.

For an added layer of softness and contouring, you can opt for the Cloud Pillow Top. This dual-layer addition enhances the plushness of the GlacioTex™ Cooling Cover and provides superior pressure relief, giving you the ultimate “sleeping on a cloud” experience.

Pros

• Responsive support for back and stomach sleepers.
• Durable build with a zoned coil system for better alignment.
• Exceptional cooling thanks to GlacioTex™ Cooling Cover.
• Available in three firmness levels for personalized comfort.
• Excellent pressure relief for side sleepers.

Cons

• Cooling cover can feel slippery for some.
• Minor quality control issues reported (e.g., stitching).
• May not suit those preferring an ultra-plush feel.

Focus on Comfort and Support

I knew it was essential to find a mattress that provided both softness and support. The AS5 Hybrid excels in this area. I found the Bio-Pur® memory foam to be especially effective at relieving pressure on the hips and shoulders, which are common pain points for side sleepers. The combination of this foam with the Active Flex foam offers just the right amount of support, without being too firm or too soft. This was a big factor in choosing it for the list.

Cooling Features

I also wanted to ensure the mattress had cooling technology, as many soft mattresses can feel too warm. After evaluating the Refresh cooling cover and breathable foam layers, I felt confident that this mattress would keep sleepers cool throughout the night. This cooling technology addresses a common concern, especially for people who tend to sleep hot.

Durability

Lastly, I took durability seriously. The AS5 Hybrid is built to last, and I was impressed by its 20-year warranty and the quality of its materials. I believe durability is crucial for long-term value, and this mattress checks that box without compromising on comfort.

These factors made it an easy pick for the list.

The Dreamy, Pressure-Free Experience

I could feel the Bio-Pur® foam layer gently cradling my pressure points—especially around my shoulders and hips. This made a huge difference when compared to firmer mattresses, which can often cause discomfort and wake me up in the middle of the night.

• What I felt: Cradling comfort, zero pressure on hips or shoulders, excellent spinal alignment.
• What others say: “It’s like sleeping on a pillow. My hips and shoulders are finally relieved from the pain they’d always experience on firmer mattresses,” shared Otterman, who also noted that the AS5 Hybrid was the most comfortable mattress they owned across multiple homes.

Comfort, but Not Ideal for Deep Sinkage

Back sleeping on the AS5 Hybrid was a bit different. I did feel a soft, plush embrace as I lay on my back, but my hips did sink in a bit more than I’d prefer for optimal spinal alignment. The Active Flex foam layer did provide some support, but for my taste, I could have used a touch more firmness to keep my spine in a neutral position.

• What I felt: Softness, slight sinkage, not quite enough support for the lower back.
• Customer feedback: Lefty, who has physical challenges including deformed hips and shoulders, found relief in the AS5 Hybrid, stating, “It’s the holy grail of mattresses for back support and comfort—finally no more hip pain.”

Not Quite Firm Enough

For stomach sleepers, the AS5 Hybrid didn’t quite meet the mark. As I lay on my stomach, my hips sank lower than I expected, which could easily cause strain on my lower back if I stayed in that position for too long.

• What I felt: Excessive sinkage around the hips, and discomfort in the lower back.
• Other opinions: Pablo, another reviewer, described the mattress as “great and soft,” but noted that he found it could be “a little firmer,” especially when sleeping on his stomach. His observation about softness echoed my sentiments when it comes to stomach sleeping.

A Balancing Act

For combination sleepers, the AS5 Hybrid delivers a mix of comfort and support. The mattress responded quickly as I shifted between positions, whether moving from my side to my back or back to my side. The foam layers adjusted rapidly, preventing that “stuck” feeling that sometimes happens on softer mattresses.

• What I felt: Quick adjustment to movement, but occasional misalignment when switching from side to stomach.
• Customer feedback: Lefty mentioned that the mattress was perfect for side sleeping and gave good relief for back pain, though like me, they noted the mattress might not be firm enough for constant stomach sleeping.

1. Ultra-Breathable Comfort Cover

The AS5 Hybrid starts with a soft, ultra-breathable cover designed to help regulate temperature. This cover allows air to flow freely, which helps prevent overheating during the night and keeps the sleep surface cool, ensuring you remain comfortable all night long.

2. Bio-Pur® Memory Foam

The next layer is Amerisleep’s Bio-Pur® foam, which is open-celled and highly breathable. This foam is more cooling than traditional memory foam, thanks to its structure that promotes airflow. Not only does it help with temperature regulation, but it also contours to your body to relieve pressure points. Unlike some other soft foams, it doesn’t make you feel “stuck,” as it bounces back quickly when you shift positions.

3. Active Flex Foam

Adding to the comfort is the Active Flex foam, which provides extra softness while maintaining support. This layer immediately cradles your body when you lie down, offering a plush feel. Importantly, it rebounds quickly, so you can shift positions easily without feeling like you’re sinking too deeply into the mattress.

4. Zoned Support System

A zoned support system is incorporated to target pressure relief. This patented design reduces pain-causing pressure points and improves spinal alignment by providing more support in areas like the hips while offering extra softness around your shoulders. This ensures that side sleepers, in particular, benefit from proper support and comfort throughout the night.

5. Pocketed Coils for Boosted Support

At the core of the AS5 Hybrid lies the pocketed coil system, which delivers responsive, bouncy support from head to toe. These coils compress individually to relieve pressure while keeping the body properly aligned. The coils are also double-dense around the edges to improve edge support, making it easier to get in and out of bed.

6. Transition Foam

A thin layer of transition foam lies beneath the pocketed coils, adding a touch of comfort while providing structural integrity to the mattress. This foam layer contributes to the mattress’s overall durability and ensures that the coils work efficiently, maintaining the mattress’s resilience over time.

7. Firm Edge Support

Finally, the AS5 Hybrid features firm edge support that reinforces the perimeter of the mattress. This not only enhances durability but also provides a more stable surface, making it easier to get in and out of bed. The extra firmness around the edges helps prevent sagging, ensuring that the mattress maintains its shape over the long term.

Pros:

• Good motion isolation for couples
• Quality construction with eco-friendly materials
• Excellent pressure relief for side sleepers
• Soft, plush feel ideal for comfort
• 100-night sleep trial and 20-year warranty

Cons:

• Not firm enough for back or stomach sleepers
• Can feel too soft for those who need more support
• Expensive compared to other options

A Budget-Friendly Pick with Performance in Mind

I chose the Zoma Start Mattress for a few key reasons:

• Cooling Comfort: I was impressed by the AirCloth cover and gel-infused memory foam. These features work together to keep you cool and comfortable throughout the night, especially for those who tend to sleep hot.
• Targeted Support: TI found the three-layer construction, including the responsive Reactiv™ layer, offers a good balance of comfort and support. It’s designed to alleviate pressure points and promote proper spinal alignment, which can be especially beneficial for side sleepers.
• Durability and Warranty: I noticed that Zoma backs their mattresses with a 10-year warranty, which shows their confidence in the product’s durability. This long warranty period provides peace of mind knowing that your investment is protected.
• Value for Money: The Zoma Start offers great value for the price. It provides many features in more expensive mattresses, such as cooling technology and pressure relief, without the premium price tag.

A Solid Choice for a Restful Night’s Sleep

After careful consideration, I believe the Zoma Start Mattress is a solid choice for anyone seeking a comfortable, supportive, and affordable mattress. Its combination of cooling technology, pressure relief, and responsive support make it a great option for a wide range of sleepers.

Responsive and Supportive

I’ve always been a bit of a restless sleeper, tossing and turning throughout the night. But with the Zoma Start, I’ve found that I can easily shift positions without feeling stuck. The Reactiv™ layer provides just the right amount of bounce, making it easy to move around and find my perfect sleep position. I also appreciate the edge support, which keeps me from feeling like I’m going to roll off the bed.

Cool and Comfortable

As a hot sleeper, I’ve struggled to find a mattress that keeps me cool all night long. The Zoma Start’s cooling gel memory foam and breathable AirCloth cover have been a game-changer for me. I no longer wake up drenched in sweat, and I can finally sleep through the night without tossing and turning.

A Dream Come True

I’ve never felt more comfortable and supported on a mattress. The Zoma Start has truly transformed my sleep experience. I wake up feeling refreshed and ready to take on the day. Let’s see the experience of others.

• Side Sleepers Rejoice: “I’ve struggled with shoulder pain for years. This mattress has been a game-changer. It provides the perfect balance of softness and support, relieving pressure and allowing me to sleep soundly through the night.”
• Back Sleepers Find Their Sweet Spot: “As a back sleeper, I need a mattress that supports my lower back without being too firm. The Zoma Start strikes the perfect balance, keeping my spine aligned and relieving any tension.”
• A Cooler Night’s Sleep: “I’m a hot sleeper, and this mattress has been a lifesaver. The cooling gel memory foam and breathable cover keep me cool and comfortable all night long.”

Cover:

• Made from breathable AirCloth fabric to wick away moisture and keep you cool throughout the night.
• The fabric is also ultra-stretchy and soft for enhanced comfort.

Comfort Layer:

• A 1-inch layer of gel-infused memory foam provides a soft, conforming surface that contours to your body shape, relieving pressure points.
• The cooling gel beads embedded in the foam help to regulate body temperature, keeping you cool and comfortable throughout the night.

Support Layer:

• A 1-inch layer of Reactiv™ foam offers a responsive bounce and added support.
• This layer prevents you from sinking too deeply into the mattress, helping to maintain proper spinal alignment and minimizing the risk of morning aches and pains.

Base Layer:

• An 8-inch layer of high-density support foam provides a firm and durable foundation for the mattress.
• This base layer helps to prevent sagging and maintain the mattress’s shape over time, ensuring long-lasting comfort and support.

Additional Features:

• Zoma Start mattresses are CertiPUR-US certified, meaning they are made without harmful chemicals like formaldehyde, phthalates, and ozone depleters.
• They are also free of heavy metals and known carcinogens.
• Zoma offers a 100-night risk-free trial and a 10-year warranty on their mattresses.

Pros:

• Gel-infused memory foam and breathable AirCloth cover for cooler sleep.
• Contours to your body to alleviate pressure points.
• Reactiv™ layer provides bounce and prevents sinking.
• High-density support foam for long-lasting comfort.
• Offers great value for the price.

Cons:

• May not be ideal for couples.
• Might not provide enough support for heavier individuals.

• Pressure Relief: A mattress needs to provide proper support without sacrificing comfort, especially for side sleepers. I analyzed how the Sparrow Hybrid relieved pressure on the hips and shoulders, and it performed well. The combination of coils and memory foam gave a great level of cushioning without feeling too plush.

• Spinal Alignment: For back sleepers, spinal alignment is crucial. The hybrid construction of the Sparrow Hybrid offers just the right amount of support, helping to maintain proper posture throughout the night, which is essential for a restful sleep.
• Thermic Phase Change Cooling: Heat retention is a common complaint with memory foam mattresses. To address this, the Sparrow Hybrid integrates cooling technology designed to maintain a neutral temperature. After testing, I found that the cooling layer works well, keeping the mattress comfortable even during warm nights.
• Gel Memory Foam: In addition to the cooling fabric, the gel-infused memory foam also contributes to better temperature regulation. My team and I noticed that the mattress didn’t trap heat as many others do, which allowed for more restful sleep throughout the night.

• Low Motion Transfer: One of the most important factors for couples is motion isolation. The Sparrow Hybrid has a strong coil system that absorbs motion, so one person’s movements are less likely to disturb the other. My team of testers confirmed that the mattress minimizes motion transfer, ensuring a more peaceful night’s sleep.
• Long-Term Durability: I also focused on the durability of the mattress. The Sparrow Hybrid’s construction feels robust, and after several weeks of testing, it showed no signs of wear or sagging. The coils provide excellent long-term support, and the memory foam holds up well, making it a solid choice for a lasting investment.

The Nest Bedding Sparrow Hybrid’s ability to adjust to various sleeping positions caught my attention the moment I laid down on it.

1. The medium hardness choice felt ideal for me as a side sleeper since it maintained proper spinal alignment while allowing my hips and shoulders to softly sink in.
2. I discovered that both the medium and hard selections provided great lumbar support for back sleepers, with just the right amount of contouring to guarantee good posture.
3. For stomach sleepers, the premium firm choice would probably be ideal because it offers more support to help correct the hips and spine.
4. I liked that the medium hardness let me easily switch between positions without feeling trapped because I’m a combo sleeper.
5. Couples will greatly benefit from the mattress’s responsiveness to movement and the pocketed coils’ ability to isolate motion.

Customer reviews align with my experience. Spencer D., a combination sleeper, mentioned that it took time to adjust to the medium side, but his wife liked the softer side. Dana B., a side sleeper, loved the balance of comfort and firmness, saying she sleeps more deeply now.

Both reviewers highlight how the mattress accommodates various preferences, making it a versatile choice for couples and individual sleepers alike.

1. Mattress Base (1-inch Support Foam Layer)

The bottom layer is a 1-inch base support foam made with 3 lb. density foam. This structural foam acts as a buffer between the foundation and the coil system. It ensures that the mattress stays sturdy and resilient, providing a solid foundation for the rest of the layers.

2. Coil Support (6-inch Pocketed Coil Layer)

At the core of the Sparrow Hybrid is a 6-inch pocketed coil layer. The individually wrapped coils are made in the USA at Nest Bedding’s factory and provide excellent support, with reinforced edges for enhanced edge support and responsiveness. The pocketed coils help with motion isolation, so you won’t be disturbed by a partner’s movements during the night. The coil count varies by mattress size, with the following numbers:

• Twin: 390 coils
• Twin XL: 420 coils
• Full: 494 coils
• Queen: 644 coils
• King: 840 coils
• California King: 812 coils

3. Transition Foam Layer (1-inch SmartFlow Support Foam)

Above the coils is a 1-inch SmartFlow support foam layer, which is made with 1.5 lb. density foam. This layer offers high-density airflow and is designed to transition smoothly from the comfort layer to the pocketed coils. Its ILD (Indentation Load Deflection) rating of 30 ensures the right balance of firmness and comfort.

4. Comfort Foam Layer (3-inch Energex Foam)

Next comes the 3-inch Energex foam layer, a temperature-responsive foam designed to provide pressure relief while maintaining durability. Energex foam offers the benefits of memory foam without the slow recovery time. It has a medium response that makes it more springy and breathable compared to traditional memory foam, while still offering excellent pressure relief. The foam density and firmness vary depending on the selected model:

• Plush: 3 lb. density with a 10 ILD
• Medium: 3.5 lb. density with a 20 ILD
• Firm: 4 lb. density with a 28 ILD

5. Pillow Top Cover (2-inch Quilted THERMIC® Phase Change Cover)

The top layer is a 2-inch quilted THERMIC® phase change cover, which uses 4 lb. memory foam for added comfort and cooling. This patented THERMIC® phase change technology helps regulate temperature by absorbing heat when the body or environment warms up, and releasing it as the temperature cools. This keeps the mattress from overheating, providing a more comfortable sleep surface.

The cover features two 1-inch layers of quilted gel memory foam, which give the surface a soft, comfortable feel without sacrificing the underlying support.

Pros

• Great for couples due to motion isolation
• Adjustable comfort layers for different sleeping preferences
• Offers multiple firmness options (plush, medium, firm)
• High-quality pocketed coil support system
• Good pressure relief for side sleepers
• Cooling quilted cover for added comfort
• Minimal off-gassing odor when unboxed

Cons

• May take some time to break in, especially the medium firmness
• The soft side may not provide enough support for heavier individuals
• Slightly heavy for solo setup, may require help

The Plank Mattress’s flippable design is one of the primary reasons I included it on my list. 

Sleepers who are unsure of the stiffness setting that suits them best may find this function extremely helpful. While the medium-firm side provides a little gentler sensation, the extra-firm side provides superior support. I discovered that, unlike many other mattresses, this dual firmness enables users to genuinely personalize their comfort.

I also appreciated the high-density foam used in the Plank Mattress. 

The dense foam layers provide strong support, ensuring proper spinal alignment, which is especially beneficial for back sleepers or those experiencing back pain. The firm support helps alleviate pressure points and promotes a restful sleep experience. My team of testers noted how well the foam layers distribute body weight, offering comfort without compromising on firmness.

Another reason I picked the Plank Mattress is its breathable design. 

The mattress incorporates open-cell foam technology that helps regulate body temperature, which is important for those who tend to sleep hot. The optional GlacioTex™ Cooling Cover adds an extra layer of temperature control, making it ideal for anyone looking for a firm mattress with cooling benefits.

This mattress is unquestionably firmer—nearer a 10 on a scale of 8 to 10. I was genuinely quite pleased with how nicely it supported my spine because I slept on my back. I woke up feeling supported and pain-free since the hardness maintained everything in its proper position. The thick support foam was working to keep my back from dipping, which I appreciated. A lot of customers seem to agree with me, too. Samantha said, “I’ve never woken up with less back pain, so this mattress is a win for me.”

However, as a side sleeper, I quickly realized that firmness wasn’t ideal for me. My shoulders and hips felt a bit too much pressure without enough cushioning to contour. Some side sleepers, like David, shared similar thoughts: “It’s way too firm for my side sleeping, but I think it’s perfect if you’re used to a very firm mattress.”

For stomach sleepers, this mattress delivers a solid, supportive feel. I noticed that it kept my body flat, preventing any sinking in my lower back. Even combination sleepers will enjoy how responsive it is, allowing me to shift positions without feeling stuck. Mark, a frequent position-changer, mentioned, “I love how I never feel trapped by the mattress, even when I flip from side to side.”

So, if you’re a back or stomach sleeper, you’ll probably love the support. But for side sleepers who need a little more give, it might not be the best match.

Optional: GlacioTex™ Cooling Cover (Extra Firm Side): This cooling cover is designed to provide cooling on contact, ensuring that the mattress stays comfortable, never too hot or too cold. It’s a great addition for those who need a cooler sleeping surface, particularly on the extra firm side.

0.75” Quilted Top: The quilted top layer adds a subtle softness to the mattress without compromising the firm support. It helps create a more comfortable surface for sleeping, safeguarding your extra-firm experience by providing just a touch of cushion.

6” High-Density Support Foam: This thick foam layer offers deep compression support, making sure you stay supported throughout the night. It’s essential for delivering the firmness that defines the Plank Mattress, ensuring that your spine is aligned and your back gets the necessary support.

2” Supreme Response Comfort Foam: The supreme response foam adds just enough contouring to the mattress, giving you firm support while preventing pressure build-up on your body. It’s crafted to balance comfort and firmness for a restful sleep experience.

0.75” Quilted Bottom: The quilted bottom layer features track-and-jump stitching to ensure minimal loft, contributing to the mattress’s traditionally firm feel. This layer adds durability and enhances the mattress’s overall sturdiness.

Optional: GlacioTex™ Cooling Cover (Firm Side): Like the extra-firm side, the cooling cover on the firm side provides cooling on contact. This ensures a balanced sleep experience for sleepers who need firm support without feeling overheated, offering a consistent cool feel throughout the night.

Pros:

• Extremely firm support, ideal for back and stomach sleepers
• Quick responsiveness for easy position changes
• High-density support foam offers deep compression support
• Cooling options available with GlacioTex™ cover for temperature control
• Minimal sinkage and great spinal alignment for back sleepers

Cons:

• Too firm for side sleepers, may cause pressure points
• Lacks sufficient cushioning for those who prefer a softer feel
• Not suitable for those looking for plush comfort
