Amerisleep AS6 Mattress Review

Our Review Process: Each mattress we review undergoes a rigorous evaluation process. We assess comfort, support, cooling, and durability through both subjective experiences and objective tests.

Criteria include pressure relief, spine alignment, mattress responsiveness, motion transfer, edge support, and temperature regulation. This comprehensive approach ensures our reviews are thorough and unbiased.

I. Mattress Layers, Materials, and Construction

At the foundation of the Amerisleep AS6 lies the PrecisionCoil core, a sophisticated network of individually pocketed coils that create a responsive base. When I lay on the mattress, I can feel how these coils work in harmony, adapting to my movements while maintaining consistent support from edge to edge.

The foam encasement around these coils provides excellent edge support. I can sit comfortably on the side without that precarious feeling of sliding off.

Moving upward, there’s an affinity foam transition layer that acts as an intermediary between the coils and comfort layers. This thoughtful addition ensures I don’t feel the coils beneath while allowing the support to flow smoothly through the mattress’s layers. It’s like having a diplomatic mediator between firm support and plush comfort.

The comfort layer features BioPur® foam, a plant-based memory foam that feels distinctly different from traditional memory foams I’ve experienced. I’ve appreciated it before in other Amerisleep mattresses like the best-selling AS3, but here it really made its mark as part of a luxurious whole.

See, while conventional memory foam can sometimes feel like quicksand, this BioPur® layer responds more quickly to movement while still conforming to my body’s contours. It’s as if the foam anticipates my movements, creating a harmonious dance between support and comfort.

What truly sets this mattress apart is its sophisticated cooling system. The Arctic Wave cooling bands, strategically placed throughout the mattress, act like thermal highways, continuously channeling heat away from my body.

Above this lies the TitanAir layer, a titanium-infused memory foam that feels cool to the touch and maintains its temperature-regulating properties throughout the night.

The crown jewel is the CryoCool cover, which creates an immediately noticeable cooling sensation. When I first touch the mattress, it’s as if I’m placing my hand on a cool stream, it’s that refreshing and invigorating.

This cooling effect isn’t just a momentary sensation, either. It persists throughout the night, maintaining a comfortable sleep temperature.

The overall construction creates a 15-inch profile that looks and feels substantial. Each layer works in concert with the others, creating a sleep surface that’s both supportive and indulgent.

The mattress responds to my movements without delay, never leaving me feeling trapped or restricted. It’s like floating on a perfectly calibrated cloud that knows exactly how much support to provide at each point of contact.

What impresses me most is how these technical innovations translate into tangible comfort. The mattress has achieved that elusive balance between the plush comfort we crave and the firm support our bodies need.

Whether I’m sleeping on my back, side, or stomach, the AS6 adapts to my position while maintaining proper spinal alignment. This is a testament to the thoughtful engineering behind each layer, and I’ll discuss more of my thoughts there in the next section!

II. Sleeping Positions

How a mattress performs across different sleeping positions is necessary to know because we all have unique ways of sleeping that affect our comfort and support needs.

Like how a couch needs to be comfortable whether you’re sitting up straight, leaning back, or perched on the edge—a mattress similarly needs to accommodate various positions our bodies take throughout the night.

When testing the AS6, I evaluated its performance across all major sleep positions, paying careful attention to how the mattress’s sophisticated layering system and three firmness options adapt to each position’s distinct requirements. This comprehensive testing is essential because the wrong support in any position can lead to discomfort or even pain over time.

What makes this evaluation particularly interesting is how the AS6’s multiple firmness options and advanced materials work together differently for each position.

Just as a sophisticated suspension system in a car needs to handle both smooth highways and rough terrain, a premium mattress should adapt to various sleep positions while maintaining proper spinal alignment and pressure relief.

Let me walk you through how the AS6 performs in each position, sharing my detailed testing process and observations that led to these conclusions.

Side Sleeping

When testing a mattress for side sleeping, I pay particular attention to shoulder and hip pressure points, as these areas bear the most weight in this position. The plush version of the AS6 proved to be an exceptional choice for dedicated side sleepers.

As I lay on my side, I noticed how the comfort layers allowed my shoulder and hip to sink in appropriately while maintaining proper spinal alignment. I was particularly impressed with how the Bio-Pur foam responded to pressure points.

Unlike traditional memory foam that can create a “stuck” feeling, the AS6’s comfort layers provided immediate pressure relief while still allowing easy movement. When I checked my spinal alignment using a mirror technique, I could see that my spine maintained a neutral horizontal line from neck to tailbone. Exactly what you want to see in side sleeping.

The medium firmness option also performed well for side sleeping, though not quite as conforming as the plush. I found it particularly suitable for side sleepers who switch positions occasionally or those who prefer not to sink too deeply into their mattress.

However, I noticed that heavier individuals (over 230 pounds) might find even the plush version too firm, as they may press through the comfort layers to the firmer support core.

Back Sleeping

Testing a mattress for back sleeping requires careful attention to lumbar support and overall spinal alignment. The medium firmness version of the AS6 truly excelled here. When lying on my back, I could feel how the mattress provided ideal support under my lumbar region while allowing just enough give to maintain the natural curve of my spine.

I performed what I call the “hand test,” sliding my hand under my lower back to check for proper support. The space was just right—not too tight (which would indicate insufficient support) and not too loose (which would suggest over-arching).

The zoned support system was particularly noticeable in this position, providing firmer support where needed while allowing my shoulders and hips to sink in appropriately.

The firm version also performed exceptionally well for back sleeping, particularly for those over 180 pounds. During testing, I noticed excellent weight distribution across my back without any gaps in support.

Stomach Sleeping

Stomach sleeping requires the firmest support to prevent excessive hip sinking, which can lead to back pain. The firm version of the AS6 clearly stood out as the best option for this position.

During testing this mattress for stomach sleeping, I paid close attention to hip elevation and spinal alignment. The mattress kept my hips elevated and aligned with my shoulders, preventing the lower back arching that often occurs with softer mattresses.

What impressed me was how the cooling properties remained effective even with full front body contact – a common issue with many cooling mattresses. However, I found that the medium firmness could work for lightweight stomach sleepers (under 130 pounds), but allowed too much hip sinking for average and heavier weights.

Combination Sleeping

Testing a mattress for combination sleeping is particularly complex as it requires evaluating not just comfort in each position, but also the ease of transition between positions. The medium firmness version proved to be the most versatile option here.

During my testing, which involved regular position changes throughout the night, I found it provided adequate support and comfort in all positions. The responsiveness of the Bio-Pur foam made position changes remarkably easy, crucial for combination sleepers.

I never experienced that “fighting with the mattress” feeling that can occur with traditional memory foam. The cooling properties remained consistent regardless of position, which is particularly important as combination sleepers tend to generate more heat through movement.

What particularly stood out was how the mattress maintained proper spinal alignment even during position changes. The transition layers helped prevent any sudden drops or jarring movements that could disrupt sleep.

For true combination sleepers who use all positions equally, I found the medium firmness provides the best overall balance of comfort and support.

However, those who favor certain positions might prefer either the plush (for predominantly side sleeping) or firm (for mainly back and stomach sleeping) versions.

III. Mattress Responsiveness

Responsiveness matters because we move dozens of times during sleep, even if we don’t remember doing so. A responsive mattress immediately readjusts to support these position changes, preventing that frustrating “quicksand” feeling that can disrupt your sleep cycle.

Just imagine trying to dance while standing in wet sand versus on a sprung dance floor. A responsive mattress, like that sprung floor, should adapt quickly to your movements rather than leaving you feeling stuck or restricted.

This quality becomes especially important for combination sleepers who switch positions frequently, and for couples, since the mattress’s ability to respond quickly helps maintain comfort during movement while minimizing disturbance to your partner.

After thorough testing, I’m giving the AS6 a 9 out of 10 for responsiveness, and I’ll walk you through exactly how I reached this assessment.

My testing protocol for responsiveness involves several specific assessments designed to evaluate both immediate and delayed response. First, I performed what I call the “hand-press test” across different areas of the mattress.

When pressing firmly into the surface and quickly removing my hand, the Bio-Pur® foam responded remarkably fast, taking just 1-2 seconds to fully regain its shape. This is significantly quicker than traditional memory foam, which often takes 4-5 seconds or longer to recover.

I repeated this test in multiple spots to ensure consistent performance across the mattress surface.

For real-world movement testing, I conducted what I call the “sleep transition test.” This involved lying in one position for 10 minutes to allow the foam to conform, then timing how quickly and easily I could switch to another position.

The AS6 performed exceptionally well here. Unlike traditional memory foam mattresses that can create a “stuck” feeling, I could easily roll from my back to my side without feeling trapped or having to consciously exert extra effort.

To evaluate dynamic responsiveness, I performed a series of movement tests that replicate common sleep behaviors: sitting up quickly from a lying position, getting in and out of bed from different angles, and making rapid position changes like you might during a restless night.

The AS6 maintained its responsive nature throughout these tests, with the comfort layers quickly adapting to each new position without the delayed bounce-back commonly found in other premium foam mattresses.

To verify the durability of this responsiveness, I performed repeated compression tests in the same spots over several days.

The mattress maintained consistent recovery times throughout, suggesting the responsive properties should hold up well over time. This resilience is particularly impressive given the plush, conforming nature of the comfort layers.

What makes the AS6’s responsiveness particularly noteworthy is how it balances quick recovery with pressure relief.

Often, mattresses sacrifice one for the other, either responding quickly but feeling too firm, or providing excellent pressure relief but responding slowly.

The AS6 manages to achieve both, thanks to its sophisticated foam formulation and hybrid construction.

The Bio-Pur® foam plays a crucial role here. Unlike traditional memory foam that can feel sluggish, this plant-based foam has an open-cell structure that allows it to both conform to your body and spring back quickly when you move.

During testing, this translated into a sleep surface that felt both supportive and adaptable, never hindering natural movement patterns during sleep.

This level of responsiveness particularly benefits active sleepers and those who may need to change positions frequently due to joint pain or other conditions.

The mattress works with your movements rather than against them, potentially helping to reduce the effort required to adjust positions during the night.

The only reason it didn’t receive a perfect 10 is that some hybrid mattresses with latex layers offer slightly quicker response times.

However, the AS6’s responsiveness is remarkable for a mattress with memory foam components, and the slightly slower response actually helps maintain pressure relief while still allowing easy movement.

IV. Mattress Motion Isolation

The ability of a mattress to isolate motion is crucial for anyone sharing a bed, much like how a well-designed building isolates noise between apartments. When one person moves, their partner shouldn’t feel disturbed, whether it’s a midnight bathroom trip or just changing sleeping positions.

After extensive testing, I’ve awarded the AS6 a perfect 10 out of 10 for motion isolation, and let me explain exactly how I reached this conclusion.

My testing protocol for motion isolation involves several carefully designed experiments that simulate real-world scenarios. Think of it like testing a car’s suspension. You want to know how it handles both small bumps and major impacts.

First, I conducted the well-known “water glass test.” I placed a glass filled with water on one side of the mattress and performed various movements on the other side, from gentle position changes to more dramatic movements. The water in the glass remained remarkably still, showing minimal surface ripples even during my most vigorous movements.

To quantify the motion transfer more precisely, I used two 10-pound medicine balls. I dropped one ball from different heights (4, 8, and 12 inches) while observing how much the other ball, placed 12 inches away, moved in response.

The results were impressive. The second ball showed virtually no movement, even with drops from the maximum height. This performance surpasses what I typically see even in other premium mattresses.

But laboratory-style tests only tell part of the story. That’s why I also conducted what I call the “sleep partner simulation test.”

While my partner slept on one side of the mattress, I performed a series of real-world movements on the other side: getting in and out of bed, changing positions, and even doing light exercises like knee raises.

My partner reported feeling no disturbance during any of these activities, a remarkable achievement for any mattress.

What makes this motion isolation particularly impressive is how it coexists with the mattress’s responsiveness. Typically, mattresses face a trade-off: better motion isolation often means less responsiveness, and vice versa.

The AS6 manages to excel at both, thanks to its sophisticated construction. The foam absorbs initial movement while the coils prevent it from traveling across the mattress.

I also tested what I playfully call the “floppy starfish test.” As you might guess, this is making large, dramatic movements while my partner had a filled water glass on their side of the bed.

Despite my exaggerated flopping around, twisting, and sudden position changes, the water glass remained remarkably stable. This test simulates those restless nights when one partner might be tossing and turning while the other tries to sleep.

The edge testing was particularly revealing. Many mattresses struggle with motion isolation near their perimeters, but the AS6 maintained its exceptional performance even when movements occurred close to the edges. This is crucial for couples sharing a smaller mattress size, where sleepers might often find themselves near the edges.

The importance of this motion isolation cannot be overstated. Poor sleep due to partner disturbance can have cascading effects on our daily lives, from reduced cognitive performance to increased stress levels. Couples with different schedules particularly benefit from this feature, as one partner can get in or out of bed without disrupting the other’s sleep.

The AS6’s perfect score in this category means that both partners can enjoy uninterrupted sleep, regardless of their partner’s movements.

This level of motion isolation also makes the AS6 an excellent choice for light sleepers or those who are particularly sensitive to movement. The mattress effectively creates what feels like an individual sleep space for each partner, despite sharing the same surface.

It’s like having the benefits of separate beds while still sleeping together, a remarkable achievement in mattress engineering.

V. Mattress Edge Support

Edge support matters for several practical reasons. Think about how often you sit on the edge of your bed—when you’re putting on shoes, checking your phone, or just easing into bed.

Without proper edge support, these everyday activities can feel unstable, like trying to sit on a cushion that’s slowly collapsing beneath you. It’s like having a sturdy frame around a picture, providing stability and usability all the way to the borders.

For couples sharing a bed, strong edge support effectively increases the usable sleep surface, allowing both partners to spread out and use the entire mattress without feeling like they might roll off when sleeping near the edges.

For those with mobility challenges, edge support becomes even more critical. Getting in and out of bed requires a stable surface that won’t suddenly compress or give way.

My testing protocol for edge support involves several specific assessments designed to replicate real-world use. First, I conducted what I call the “perimeter sitting test.” This involves sitting on various points around the edge of the mattress, simulating common activities like putting on shoes or getting ready for bed. The AS6 performed exceptionally well here. I felt stable and supported, with minimal sinking.

The reinforced perimeter coils (which are 35% stronger than the interior coils) provided a surprisingly bench-like stability that you rarely find in foam-hybrid mattresses.

Next, I performed the “progressive weight test,” where I gradually shifted more of my body weight toward the edge while sitting. This helps evaluate how the edge support responds to increasing pressure.

The AS6 maintained its structural integrity impressively well under increasing load, though there was slightly more compression than you might find in an all-latex or traditional innerspring mattress. Hence the 9 rather than a perfect 10.

For sleeping positions, I tested what I call the “edge sleeping protocol.” This involves lying in various positions (side, back, and stomach) with a portion of my body weight near the edge of the mattress.

The AS6 provided consistent support in all positions, with no sensation of roll-off even when I purposely positioned myself right at the edge. This is particularly impressive for a mattress with sophisticated comfort layers, as these can sometimes compromise edge stability.

The corner testing was particularly revealing. Mattress corners are often the weakest points in terms of support, but the AS6’s reinforced corner construction maintained similar stability to the straight edges.

When sitting on or pressing into the corners, I noticed only slightly more compression than along the straight edges. A performance that surpasses many competing luxury mattresses.

I also conducted durability testing by repeatedly compressing the edges to simulate years of use. The reinforced perimeter showed excellent resilience, returning to its original shape quickly and maintaining consistent support throughout the testing period. This suggests the edge support should maintain its performance over the mattress’s lifespan.

As I mentioned, edge support can be a necessity for those with mobility challenges. The AS6’s robust edge support provides that recommended stability, making it easier to transition from sitting to standing or vice versa. During testing, I found the edges maintained their support even under the dynamic pressures of these movements.

The only reason the AS6 didn’t receive a perfect 10 for edge support is that there was slightly more compression than you might find in some traditional innerspring mattresses with ultra-rigid perimeter systems. However, this minor give actually contributes to overall comfort while sitting, as it allows for some natural conforming to your body rather than feeling like you’re sitting on a wooden bench.

This level of edge support is particularly impressive given the mattress’s plush comfort layers and sophisticated cooling technology. Often, mattresses must sacrifice some edge stability to accommodate advanced comfort features, but the AS6 manages to provide excellent edge support while maintaining its premium feel throughout the entire surface.

VI. Cooling and Breathability

Our bodies naturally need to cool down by 2-3 degrees Fahrenheit to initiate and maintain quality sleep. And a mattress that retains heat essentially creates a personal sauna beneath you, disrupting this natural cooling process and interfering with your sleep cycles.

Cooling mattresses are important overall, but especially for certain groups of sleepers:

• For couples sharing a bed, the combined body heat can make temperature regulation even more challenging. The AS6’s cooling system effectively manages the increased thermal load from two bodies.
• Those experiencing night sweats or hormonal changes often find their sleep disrupted by temperature fluctuations. The consistent cooling properties of the AS6 help maintain a stable sleep environment throughout the night.
• People living in warmer climates particularly benefit from a mattress that actively works to maintain optimal sleep temperature, rather than just trying to avoid heat retention.

The AS6 earns its perfect 10/10 score through what I found to be an exceptionally well-engineered approach to temperature regulation. Where many cooling mattresses rely on a single solution, like gel-infused foam or a cooling cover, the AS6 implements a sophisticated triple-cooling system that works in harmony to maintain optimal sleep temperature.

Starting at the surface, the CryoCool cover provides an immediate sensation that’s notably different from other cooling mattresses I’ve tested. When I placed my hand on the surface, I could feel the cooling effect within seconds. It’s not just marketing language, but a tangible effect.

The second layer of cooling technology, the TitanAir layer, works in concert with the cover. This titanium-infused memory foam helps dissipate heat efficiently while still providing the pressure relief you’d expect from premium memory foam.

During my time testing the mattress, I noticed that even after lying in one position for an extended period (something I specifically test for), the surface maintained its cool feel rather than developing hot spots like many memory foam mattresses do.

Perhaps most impressively, the ArcticWave cooling bands provide a third layer of temperature regulation that maintains cooling performance for over 12 hours. Noteworthy, because many cooling mattresses tend to lose their effectiveness after a few hours.

These bands are strategically placed throughout the mattress to create channels for heat dissipation, working like a network of thermal highways to move heat away from your body.

What sets the AS6 apart from other cooling mattresses I’ve tested, even others that have earned perfect scores, is its ability to maintain consistent temperature regulation without sacrificing comfort or support.

Many cooling mattresses achieve their temperature control through firmer surfaces or gel-infused foams that lose effectiveness over time. The AS6’s approach is more sophisticated and sustainable, even compared to many that I’ve given top scores to:

• Amerisleep AS5 Hybrid
• Zoma Boost
• Nolah Evolution 15
• Brooklyn Bedding Aurora Luxe
• GhostBed Flex

During my testing, I evaluated the cooling performance under various conditions. With different types of bedding, in different room temperatures, and with varying levels of physical activity before sleep.

The mattress maintained its cooling properties consistently across these scenarios. Even when using a moderately thick comforter or duvet, the sleep surface remained noticeably cool, though I would recommend using breathable bedding to maximize the cooling benefits.

It’s worth noting that while the AS6 earns a perfect score for cooling capabilities, personal experiences may vary based on factors such as room temperature, bedding choices, and individual temperature sensitivity.

However, the comprehensive approach to cooling technology and consistent performance make it one of the most effective temperature-regulating mattresses currently available in the market.

VII. Durability and Longevity

Based on my extensive testing and analysis, I expect the AS6 to maintain its key performance characteristics for 8-12 years under normal use conditions.

However, I want to be transparent about why predicting exact mattress longevity is more complex than it might seem. Having tested hundreds of mattresses over the years, I’ve learned that durability involves multiple interacting factors that can significantly impact a mattress’s lifespan.

The foundation of my confidence in the AS6’s durability starts with its materials. The mattress uses high-density Bio-Pur® foam (3.5 PCF) and titanium-infused memory foam (4.0 PCF), which I’ve found typically outlast standard memory foams.

From my experience testing mattresses over extended periods, these higher density foams tend to maintain their shape and support characteristics better than the 1.8-2.5 PCF foams commonly found in mid-range mattresses.

The 15-inch profile also contributes to my confidence in how long the mattress will last. Having tested mattresses of varying heights over the years, I’ve consistently found that thicker mattresses tend to show less compression over time. Simply because they have more material to distribute weight and pressure.

So yes, the AS6’s substantial height provides more room for the comfort layers to recover between uses.

Yet, I’ve also seen how individual usage patterns can dramatically affect longevity. A mattress that might last 12 years for a 140-pound side sleeper could show significant wear after just 6-7 years when used by a 230-pound back sleeper. This variability is one reason I’m careful about making absolute predictions about durability.

Looking further at the structural elements, though, I’m particularly encouraged by the PrecisionCoil support system. In my experience testing hybrid mattresses, individually wrapped coils tend to maintain their supportive properties longer than traditional innerspring systems.

The reinforced perimeter coils in the AS6 should also help maintain edge support over time, though I typically advise users to avoid overusing this part where they can. Don’t get lost scrolling through your phone in the morning like I have!

The AS6’s sophisticated cooling technology presents another interesting wrinkle for longevity. While I’m impressed by the immediate cooling effects of the CryoCool cover and TitanAir layer, we have limited long-term performance data for these newer technologies.

See, in my testing of older cooling mattresses, I’ve noticed that some cooling properties can diminish over time, though the AS6’s triple-cooling system seems more robust than most I’ve encountered.

Amerisleep’s 20-year warranty offers another interesting perspective on durability. While I never take warranty periods at face value (having seen many mattresses deteriorate well within their warranty period), the fact that they offer full replacement for the first decade suggests confidence in their construction.

From my experience, this aligns with what I’ve observed in their materials and build quality, having tested several Amerisleep mattresses.

However, I should note that even a durable mattress may not remain comfortable for its entire physical lifespan. I’ve seen cases where mattresses maintain their structural integrity but lose their initial comfort characteristics. The cooling properties, pressure relief, and response time might gradually change even if the mattress hasn’t technically “failed.”

Environmental factors also play a crucial role in longevity. Through years of mattress testing, I’ve observed how factors like room temperature, humidity, and direct sunlight can affect foam performance over time.

The AS6’s sophisticated materials might be particularly sensitive to these conditions, which is why I emphasize proper maintenance and placement.

Based on all these factors, while I’m confident in projecting 8-12 years of quality performance for the AS6, I always advise users to monitor their sleep quality and comfort rather than focusing solely on age. A mattress that’s physically intact but no longer providing optimal sleep isn’t serving its primary purpose, regardless of its expected lifespan.

I also suggest owners rotate their mattress regularly to ensure even wear. This deters the sagging and body impressions that can build up from using one spot over and over.

So while the AS6 shows all the markers of a durable, long-lasting mattress, its actual lifespan will ultimately depend on a complex interplay of usage patterns, care practices, and environmental conditions.

VIII. Potential Drawbacks

When investing in a premium mattress like the AS6, which represents a significant financial commitment and will impact your sleep for years to come, it’s crucial to have a complete picture. Not just the highlights, but also the practical limitations and considerations that might affect your experience.

Just as a high-performance vehicle might require premium fuel and specialized maintenance, a sophisticated mattress like the AS6 comes with its own set of considerations that might not be immediately apparent. These limitations don’t necessarily make the AS6 a poor choice. In fact, it remains an excellent mattress for many sleepers.

However, understanding these potential drawbacks helps set realistic expectations and ensures you can make an informed decision about whether this mattress aligns with your specific needs and circumstances. While the generous sleep trial gives you the space and time to see if a mattress is right for you, I always like to save shoppers the trouble where I can.

Let’s examine each of these potential drawbacks in detail, from the most immediate concerns like price and physical characteristics to more nuanced considerations like maintenance requirements and comfort limitations.

This way, you can weigh these factors against the mattress’s benefits and determine if it’s the right choice for your situation.

Price Considerations

The most immediate hurdle for many potential buyers is the AS6’s premium pricing. There’s no way to sugarcoat it, this mattress represents a substantial investment.

While Amerisleep often offers promotional discounts (like their current $1,000 off deal), the price point remains in the luxury category. This cost becomes particularly significant when we consider that many quality mattresses are available in the $1,000-$1,500 range.

The advanced cooling technology and premium materials justify the price, but not everyone’s budget can accommodate such an investment.

Height and Physical Characteristics

The 15-inch profile of the AS6 creates several practical challenges. First, you’ll need to purchase deep-pocket sheets, which typically cost more than standard sheets and may be harder to find. This extra expense should be factored into your total investment.

The height can also make the mattress challenging to get in and out of, particularly for shorter individuals or those with mobility issues.

Additionally, the mattress’s substantial weight (110 pounds for a queen size, 140 pounds for a king) makes it difficult to move the mattress or rotate it. This becomes particularly problematic during the recommended quarterly rotation for maintenance.

While the mattress includes handles, you’ll still need assistance to move it properly, which could be inconvenient for those living alone.

Maintenance Requirements

The sophisticated cooling technology and premium materials require specific care to maintain their effectiveness. The CryoCool cover, while innovative, needs careful attention when cleaning the mattress. Only spot cleaning is recommended, and using the wrong cleaning products could potentially damage the cooling properties.

The requirement for specific care might be more maintenance than some users want to manage with their mattress.

Breaking-In Period

Like many premium mattresses, the AS6 requires a break-in period. Taking 30-45 days to fully adjust to the mattress’s feel isn’t uncommon, particularly if they’re transitioning from a different type of sleep surface.

During this period, you might experience temporary discomfort or slight body aches as your body adapts to the new support system. While this is normal and temporary, it can be frustrating for those expecting immediate comfort.

Firmness Limitations

Despite offering three firmness options, some sleepers might still find themselves between comfort levels. Very lightweight individuals (under 130 pounds) might find even the soft version too firm, as they don’t have enough body weight to fully engage the comfort layers.

Conversely, heavier individuals (over 230 pounds) might experience too much sinking with the plush version, even though it’s designed to be supportive.

Temperature Regulation Trade-offs

While the Triple-Cooling System is highly effective, it can actually feel too cool for some sleepers, particularly in colder climates or during winter months. There’s no way to “turn off” or reduce the cooling features. Additionally, the cooling technology works best with breathable, lightweight bedding – using heavy comforters or mattress pads can diminish its effectiveness, limiting your bedding choices.

Off-Gassing Period

When first unboxed, the AS6 typically releases a noticeable “new mattress” smell, known as off-gassing. While this is temporary and harmless (the materials are CertiPUR-US certified), it can be bothersome for those sensitive to odors.

The smell usually dissipates within a few days to a week, but some users might need to let the mattress air out in a well-ventilated room before using it.

Delivery and Setup Challenges

The mattress’s size and weight can make delivery and setup complicated. While Amerisleep offers free shipping, the package is quite heavy and bulky.

You’ll need ample space to unbox and set up the mattress, and likely assistance to move it into place. This could be particularly challenging in apartments, homes with narrow staircases, or situations where professional setup service isn’t available.

Edge Support Variability

While the AS6 generally provides good edge support, the effectiveness can vary depending on the chosen firmness level. The plush version, in particular, might not offer sufficient edge support for those who regularly sit on the bed’s edge or sleep near the perimeter.

This could effectively reduce the usable sleep surface, particularly for couples sharing a smaller size.

IX. Trial Period, Warranty, Pricing, and Sizes

When considering a luxury mattress like the AS6, understanding the complete investment picture (from trial periods to warranty coverage to pricing) becomes crucial for making an informed decision. Think of it as similar to purchasing a car: while the sticker price is important, factors like warranty coverage, return policies, and long-term value all play vital roles in the true cost of ownership.

The AS6’s pricing and policies reflect its positioning in the luxury mattress market, but with some interesting distinctions from its competitors. Where some premium mattress brands rely heavily on name recognition to command higher prices, Amerisleep has taken a different approach, offering comparable or superior features at more accessible price points.

Before diving into the specific details of trials, warranties, and pricing, it’s helpful to understand how these elements work together. A generous trial period allows you to truly experience the mattress in your home environment, while a robust warranty protects your investment over time.

The pricing structure, when viewed alongside these policies and the mattress’s features, provides a complete picture of the value proposition. Let’s examine each of these components in detail to understand what you’re really getting for your investment.

Sleep Trial

Amerisleep offers a 100-night sleep trial, which means you can try their mattress in your home for 100 nights to make sure it’s right for you. This trial period doesn’t start until your mattress arrives at your home, giving you plenty of time to really test it out. If you also order an adjustable bed base, the trial won’t start until both pieces arrive, ensuring you can try the complete sleep setup.

The sleep trial matters for several important reasons. First, when you buy a mattress in a store, you typically only get to lie on it for a few minutes. This isn’t enough time to know if a mattress will truly work for you.

Think about it like trying on new shoes. Walking around the store for five minutes feels very different from wearing them all day. Similarly, a quick test in a store can’t tell you how well you’ll sleep on a mattress night after night.

Another reason the trial period is valuable is that your body needs time to adjust to a new mattress. When you switch to a mattress with proper support, your body might need up to 30 nights to get used to the new sleeping surface.

This is completely normal. Just like how your muscles might feel sore when you start a new exercise routine. During this adjustment period, you might experience some minor aches or stiffness, but these usually go away as your body adapts to the better support.

The sleep trial also takes away the risk of making such a big purchase. Mattresses are expensive, and without a trial period, you’d be stuck with your choice even if it turns out to be uncomfortable.

With Amerisleep’s trial, if you decide the mattress isn’t right for you after trying it for at least 30 nights (but before the 100 nights are up), you can contact them to start a return.

They’ll help coordinate picking up the mattress for free and give you a full refund, no restocking or shipping fees.

Understanding the process is important too. If you need to return the mattress, Amerisleep has made it straightforward. You’ll work with their Arizona-based support team who will arrange the mattress pickup and handle your refund.

This hassle-free approach means you can focus on finding the right mattress without worrying about a complicated return process.

Remember though, that this trial only applies to mattresses. Other items like pillows, sheets, and bedding accessories are final sale and can’t be returned unless they arrive with defects. This is why it’s especially important to take advantage of the mattress trial period and make sure you’ve found the perfect fit for your sleep needs.

Mattress Warranty

When you buy a new Amerisleep mattress, it comes with a 20-year warranty that protects you if something goes wrong with the mattress. This warranty is split into two parts of 10 years each.

During the first 10 years, Amerisleep will completely replace your mattress if it has certain problems. For example, if the foam starts cracking, or if your mattress gets a deep dip in the middle that’s bigger than 1.5 inches, Amerisleep will give you a new mattress for free. However, you might need to pay for shipping the new mattress to your home.

The second 10 years work a bit differently. During this time, if your mattress has problems, you’ll need to pay half the original price of the mattress to get a replacement. You’ll also need to pay for shipping and any other costs involved in getting the new mattress.

It’s important to know what can cancel your mattress warranty. If you spill something on the mattress and it gets stained, the warranty won’t work anymore. That’s why Amerisleep suggests using a mattress protector to keep it clean.

Also, you need to put your mattress on the right kind of base. You can use a platform bed, an adjustable base, or a special foundation, but you can’t just put it on an old box spring unless you add a thick piece of plywood on top.

The warranty only works for the person who first bought the mattress. If you give the mattress to someone else or sell it, the warranty doesn’t transfer to the new owner. Also, this warranty only works if you live in the United States or Canada. If you live in Alaska, Hawaii, or Canada, you’ll need to pay extra shipping costs if you ever need a replacement mattress.

To get help with a warranty problem, you’ll need to show Amerisleep your receipt from when you bought the mattress. They might also ask you to send pictures of your mattress and the base it’s sitting on. If you ever have problems, you can call Amerisleep’s customer service at 1-800-500-4233 or send them an email.

Prices and Sizes

The AS6 Black Series is positioned in the luxury mattress segment, covering all standard mattress sizes and dimensions. The 15-inch height is particularly noteworthy as it requires deep-pocket sheets, which should be factored into the overall cost.

When we compare the AS6 to other premium cooling mattresses, we find some interesting price positioning. For instance, the Tempur-Pedic ProBreeze, a direct competitor in the cooling mattress category, typically costs about 40% more than the AS6 for comparable sizes.

Similarly, the Purple RestorePlus Hybrid with their proprietary Grid technology starts at around $2,549, and is only available in two firmnesses to the AS6’s three. This positions the AS6 as a more affordable and versatile option in the premium cooling mattress space.

It’s worth noting that Amerisleep frequently offers promotional discounts, including their current $1,000 off promotion. Even competitors’ sale prices often don’t match the AS6’s discounted rates while offering fewer features.

And while some basic mattresses might cost less initially, they often lack the durability and advanced features that can make the AS6 a more cost-effective long-term investment. When we consider the per-night cost over its expected lifespan (8-12 years), the value becomes clearer.

X. Environmental Impact

Understanding a mattress’s environmental footprint helps us make informed decisions about our purchases, especially for products we’ll use for many years.

The AS6 represents a middle ground in environmental responsibility. Better than traditional memory foam mattresses but not as eco-friendly as fully natural options.

Its combination of partial plant-based materials, efficient shipping, clean manufacturing, and long-term durability makes it a more environmentally conscious choice than many traditional mattresses.

Though there’s still room for improvement as an eco-friendly mattress in areas like end-of-life recyclability and transparency about material sourcing.

Materials

The AS6’s environmental story begins with its signature Bio-Pur® foam, which represents Amerisleep’s effort to reduce reliance on petroleum-based materials. By incorporating plant-based oils (specifically castor oil derivatives) into their foam production, they’ve taken a step toward more sustainable materials.

However, we should understand this with some nuance. While better than traditional all-petroleum-based foams, Amerisleep doesn’t disclose the exact percentage of plant-based materials used, making it difficult to quantify the environmental benefit.

It’s like occasionally taking public transport. It’s better than driving everywhere, but not quite the same as going completely car-free.

The AS6’s foams are CertiPUR-US® certified, ensuring they’re made without ozone depleters, certain harmful flame retardants, and heavy metals. While this certification provides some environmental assurance, it’s also worth noting that this has become more of an industry standard rather than a distinguishing feature.

The mattress also meets GREENGUARD Gold standards for low chemical emissions, which is particularly relevant for indoor air quality.

Manufacturing Process

The AS6’s American manufacturing location plays a crucial role in its environmental impact. U.S. factories operate under stricter environmental regulations than many overseas facilities, ensuring better pollution control and waste management.

Amerisleep employs what they call a “zero-air emissions” manufacturing process, which notably reduced off-gassing during my testing. A stark contrast to traditional memory foam mattresses that often require days of ventilation.

The domestic manufacturing also significantly reduces transportation distances compared to mattresses made overseas.

Consider that a single container ship can produce as much pollution as millions of cars, by manufacturing in the United States, the AS6 avoids this substantial environmental cost of ocean freight shipping.

Transportation and Shipping Efficiency

Amerisleep’s compression technology allows them to fit three mattresses in the space traditionally required for one uncompressed mattress, reducing shipping-related fuel consumption by up to 80%.

While this compressed shipping method has become increasingly common in the industry, it still represents an important environmental benefit. The shorter transportation distances from American factories to customers also mean fewer emissions compared to mattresses shipped from overseas.

Durability and Longevity

The AS6’s durability factors significantly into its environmental impact. Throughout my testing and research, I found evidence suggesting the mattress maintains its performance characteristics longer than many competitors.

A more durable mattress means less frequent replacement and, consequently, less environmental impact over time. The 15-inch profile and high-density foams contribute to this longevity, potentially reducing the number of mattresses that end up in landfills over time.

End-of-Life Considerations

Perhaps the biggest environmental challenge with the AS6 lies in its end-of-life disposal. Despite its partial use of plant-based materials, the synthetic foams aren’t biodegradable.

Unless you have access to specialized mattress recycling facilities, the AS6 will likely end up in a landfill where it will persist for hundreds of years. This remains a significant environmental concern.

Ways to Minimize Environmental Impact

If you choose the AS6, there are several ways to reduce its environmental footprint:

• Maximize the mattress’s lifespan through proper care and maintenance
• Use a high-quality mattress protector to prevent premature replacement
• Research local mattress recycling options for eventual disposal
• Follow the rotation schedule to ensure even wear and extended life
• Maintain proper support and foundation to prevent premature deterioration

For those prioritizing environmental impact above all else, it’s worth noting that Amerisleep’s Organica line offers more sustainable alternatives with natural latex, organic cotton, and wool.

However, if the AS6’s specific features and cooling technology meet your needs better, understanding its environmental impact can help you make an informed decision and take steps to minimize its footprint.

XI. Maintenance and Care

A premium mattress like the AS6 represents a significant investment in your sleep quality and overall wellbeing, and like any valuable investment, it requires thoughtful care to maintain its performance over time.

Through my experience with various mattresses over the years, I’ve learned that proper maintenance isn’t just about preserving the physical structure. It’s about ensuring the sophisticated technologies, from the CryoCool cover to the specialized foam layers, continue functioning as intended.

After all, each layer has been carefully designed to work in harmony with the others, and maintaining this harmony requires a systematic approach to care.

Don’t start worrying about needing to do a list of chores daily, though. The good news is that while the AS6 incorporates advanced materials and cooling technologies, its care requirements aren’t overly complex. They just need to be consistent and thorough.

Small, regular maintenance efforts can prevent larger issues from developing. What might seem like minor details (the spacing between slats in your bed frame, the type of cleaning products you use, even the amount of direct sunlight your mattress receives) can have significant long-term impacts on your mattress’s performance and longevity.

Have Good Protection

The first and most crucial step is using a high-quality mattress protector. This isn’t just a suggestion, it’s an absolute necessity.

Having previously dealt with a mattress stained by a spilled cup of tea, I can attest that liquid damage can be impossible to fully reverse. The AS6’s CryoCool cover is sophisticated technology, and while it’s durable, it needs protection from spills, sweat, and skin oils.

I recommend using a breathable, waterproof protector that won’t interfere with the mattress’s cooling properties. The mattress protector should be regularly washed according to its care instructions, typically every few months or immediately after any spills.

As you change the bedding (which I recommend doing weekly) take a few seconds to check the mattress protector for any threadbare spots.

Rotation Schedule

From my experience with previous premium mattresses, regular rotation is crucial for even wear. With the AS6, I recommend rotating the mattress 180 degrees (head to foot) every three months. I’ve found setting calendar reminders helps maintain this schedule.

This practice prevents body impressions from becoming too pronounced in any one area. Unlike some older mattresses I’ve owned, the AS6 should never be flipped. Its layers are designed in a specific sequence with the CryoCool cover always facing up.

This is top-to-bottom design has become the standard of mattresses in boxes, but I still want to emphasize that flipping

Cleaning and Spot Treatment

The cover of the AS6 should only be spot cleaned, never machine washed or dry cleaned. This isn’t an uncommon rule in my experience with mattresses, but it still always bears repeating.

When spot cleaning is necessary, I use a mild detergent mixed with cold water, applying it gently with a clean white cloth. It’s crucial to avoid saturating the mattress. Understand that less liquid is more, otherwise you risk giving mattress mold what it needs to flourish and make you sick.

I’ve learned to blot rather than rub, as rubbing can damage the fabric and potentially affect the cooling properties of the cover. Always allow the spot to dry completely before replacing the bedding.

Support and Foundation

Having previously dealt with a voided warranty due to improper support (the slats of my bed were spaced just a smidge too far apart), I’m particularly attentive to this aspect.

The AS6 needs proper support to maintain its structure and prevent sagging. If using a slatted base, ensure the slats are no more than 3 inches apart and at least 0.5 inches thick.

When using a foundation, it should be solid, flat, and capable of supporting both the mattress and its occupants. I regularly check the support system for any signs of wear or damage, as a compromised foundation can lead to mattress deterioration.

Environmental Considerations

From seeing numerous mattresses that have deteriorated due to environmental factors, I would be careful about the AS6’s placement. Direct sunlight should be avoided as it can degrade the materials over time. I use light-blocking curtains during peak sunlight hours in my bedroom, and make sure my frame is well out of the way of any window.

The room should maintain reasonable temperature and humidity levels, as extreme conditions can affect the mattress’s materials. I’ve also learned to avoid placing the mattress near heating vents or air conditioners, as dramatic temperature fluctuations can impact the cooling technology’s effectiveness.

Frequent Maintenance Checks

Every three months, when rotating the mattress, I perform a thorough inspection. I check for any unusual sagging (anything beyond 1.5 inches should be addressed under warranty), inspect the seams for any separation, and examine the cover for any signs of wear.

This regular assessment helps catch any issues before they become serious problems. Something I wish I’d done with previous mattresses.

Regular Bedding Care

Fresh, clean bedding isn’t just about hygiene. It’s about protecting your mattress investment. I wash sheets weekly in cool or warm water (never hot, as I’ve learned this can break down elastic fibers over time), and I always ensure bedding is completely dry before making the bed.

Moisture trapped between the mattress and bedding can lead to mold and mildew, something I unfortunately discovered with a previous mattress.

XII. Conclusion

After putting the AS6 through its paces like a drill sergeant at boot camp, I’m giving this luxury mattress a stellar 9 out of 10. It’s not perfect, though nothing in life is, except maybe chocolate chip cookies fresh from the oven. But it comes impressively close. Think of it as that straight-A student who got one B+ and still made honor roll.

The AS6 shines brightest in its cooling technology (no pun intended), which feels like having your own personal arctic breeze without the polar bears. The three firmness options mean there’s something for everyone, whether you sleep like a log, a pretzel, or somewhere in between.

And while the price tag might make your wallet wince, remember: you’re spending a third of your life on this thing. You might as well make it count!

Sure, it has a few quirks. The 15-inch height means you might need a stepladder if you’re vertically challenged, and moving it is like trying to wrestle a very sleepy elephant. But these are small prices to pay for what could be the best sleep of your life.

XIII. FAQs

Is the AS6 the best Amerisleep mattress?

The concept of “best” mattress is highly individual, as it depends on your specific sleep needs, preferences, and body type. The AS6 represents Amerisleep’s most advanced cooling technology and premium construction, featuring their triple-cooling system with CryoCool cover, TitanAir layer, and ArcticWave cooling bands.

While it’s their most technologically sophisticated mattress, other Amerisleep models like the AS3 or AS5 might be better choices depending on your specific needs. For instance, the AS3 is better suited for average-weight combination sleepers, while the AS6 excels for those who prioritize cooling technology and luxury features.

Meanwhile, the Amerisleep Organica Plush is the model with the highest concentration of natural materials, an area the AS6 is much weaker in. It all comes down to what’s important in a mattress for you and how much money you’re willing to spend.

Does the Amerisleep AS6 use fiberglass?

The AS6 uses a sophisticated fire barrier system that entirely avoids fiberglass, instead using an OEKO-TEX Standard 100 certified firesock made with specially treated flame-retardant textiles.

This certification ensures that all materials used in the mattress, including the fire barrier, are free from harmful substances and meet strict safety standards.

The fire protection system demonstrates Amerisleep’s commitment to both safety and health, as they’ve found a way to meet fire safety requirements without resorting to potentially harmful materials like fiberglass.

Will the Amerisleep AS6 wear out?

The AS6 is built for longevity, with Amerisleep backing this claim through their 20-year warranty, one of the longest in the industry. The mattress uses high-density foams and premium materials, including their Bio-Pur memory foam which is more durable than traditional memory foam due to its advanced open-cell structure.

Regular rotation of the mattress every three months, along with proper care and maintenance, should help the AS6 maintain its performance characteristics for many years of use.

Should I choose the soft, medium, or firm version of the AS6?

Your ideal firmness level depends primarily on your sleeping position, body weight, and personal comfort preferences. The luxury firm (medium) version offers the most versatility, working well for couples with different preferences and combination sleepers who change positions throughout the night.

Side sleepers and those who prefer a plusher feel might benefit more from the soft version, while back and stomach sleepers typically find better support with the firm option. Though, I’d encourage you to consider your body weight as well, as heavier individuals often need firmer support while lighter individuals may prefer softer surfaces.

Why would I want a luxury mattress like the AS6?

A luxury mattress like the AS6 represents an investment in your health and well-being, given that we spend approximately one-third of our lives sleeping.

The AS6’s advanced cooling technology, premium materials, and sophisticated construction work together to provide superior pressure relief, temperature regulation, and support that can contribute to better quality sleep and reduced pain or discomfort.

Furthermore, the durability of premium materials and construction means that while the initial investment is higher, the cost over time may actually be lower than replacing a less expensive mattress more frequently. Especially considering the 20-year warranty that backs the AS6.
