I. Mattress Layers, Materials and Construction

Unboxing the thoughtfully packed Amerisleep AS2, I was pleased to discover it expanded to full height almost instantly with no off-putting smells. Assessing the layered construction, I focused on the quality of materials and support system. Overall, the AS2 contains four layers.

The base layer utilizes 7-inch Bio-Core® high-density polyfoam with an impressive density rating of 2.0 pounds per cubic foot (PCF). This provides exceptional reinforcement for the layers above and a sturdy, stable feel when I tested mattress firmness and support.

Next is a 3-inch transitional Affinity foam layer with Amerisleep’s proprietary Hive® technology. Featuring hundreds of hexagonal cutouts, this zoning system relieves tension at pressure points while preventing sinkage in heavier zones. Though firmer foams diminish this layer’s effects in my experience, it still allows sensitive areas to compress.

The key comfort layer uses 2 inches of Bio-Pur® open-cell memory foam. Its advanced cell structure enhances breathability and airflow versus traditional memory foam, with rapid response time to prevent “stuck” feelings. Bio-Pur® delivered noticeable contouring without heat retention or excessive sinkage. I never felt trapped in memory foam or got too hot while sleeping on the AS2.

Finally, the high-tech Refresh Cover contains a proprietary blend of minerals and infrared-emitting fibers to convert body heat into energy, boosting blood circulation for accelerated muscle recovery. Remarkably cool-to-touch, this cover complements the mattress’s advanced temperature regulation.

Based on my trial, I can say Amerisleep’s claims ring true – I woke up refreshed, even after I may have had a strenuous workout the previous day. The AS2’s thoughtful construction and advanced materials provide exceptional comfort and support.

II. Sleeping Positions

As a medium-firm mattress (7/10 on the firmness scale), the AS2 performed excellently for my back and stomach sleeping. The AS2 delivers a carefully calculated blend of comfort and support needed for spinal alignment. Being on the firmer side, with responsive support, it would also likely be ideal for anyone seeking back pain relief.

For me as a side sleeper, it felt moderately comfortable but was still quite firm. The surface did still allow areas like my shoulders and hips to sink in gently, but not quite as much as I enjoy. Thus, I’d likely opt for Amerisleep’s softer models designed specifically for side sleepers over the AS2, such as the Amerisleep AS3.

III. Response Time – Score: 9/10

A responsive mattress is crucial as it adapts to individual body contours, providing optimal support and comfort, and ensuring a restful sleep that caters to diverse sleep preferences and positions. In other words, a quick mattress responsiveness when changing positions is so important for freedom of movement and avoiding feeling “trapped” in bed.

I’m thrilled to report that the AS2 bounces back rapidly after compression. When I stretched out on the surface, there was minimal sinkage and hug typical in memory foam while still reacting quickly to changing positions.

Even repeatedly standing and lying back down, the mattress’s structure regained form instantly. Switching from my back to side also took little effort to feel realigned, earning a superb response time score in my assessment. This quick adaptation prevented feeling “stuck in the mud” which can hurt the quality of your sleep.

I also tested the mattress using my standard responsiveness test of standing by the side of the mattress, holding a 10-pound weight above my head, and dropping it onto the bed. The weight bounced gently, and the mattress was quick to cradle it as it settled, yet snapped back into shape within seconds of the weight’s removal.

IV. Motion Transfer and Edge Support

I’ve chosen to review these two traits together as they both go together hand-in-hand, primarily coming from the mattress’s support unit. Edge support in mattresses ensures a stable sleep surface, preventing sagging and allowing full utilization of the mattress.

Mattress motion isolation minimizes disturbances, ideal for undisturbed sleep when sharing the bed, enhancing overall sleep quality.

Motion Transfer Score: 10/10

For sleeping partners, excess motion transfer can severely disturb your sleep. But with the AS2, I was impressed by how isolated, subtle movements remained.

In one of my favorite tests, I plopped some weights down beside me to score motion transfer and isolate movement. Tossing and turning as normal, the weights barely budged, showcasing stellar motion isolation.

You may have seen similar tests performed with other household objects set on the mattress, such as a glass of water, while a tester bounces on the bed to see if their movements ripple enough across the surface to knock the item. However, I prefer to test the mattress in line with expected wear and tear.

Couples should have no trouble staying undisturbed by a partner’s movements. However, if you want to be certain, you can consider the split king mattress option, which gives each partner their own mattress.

Edge Support Score: 8/10

As for edge support, the perimeter allowed me to sit comfortably without sliding off the side. To test this, I sat on the side of the bed and noted how the edge underneath me withstands my weight. I should note this can be somewhat subjective and also that I’m of an average build for a woman. Heavier sleepers may put more strain on the mattress than I do.

Many all-foam mattresses struggle with offering reinforced edges, yet Amerisleep combats this typical downfall with edges that remain supportive enough for me to spend a few minutes just sitting on the side of the bed.

However, my weight did compress the edges more substantially compared to the middle area. Still, for an all-foam construction, the AS2 holds up better than average in this category.

V. Cooling and Breathability – Score: 10/10

Between the breathable foam layers and cooling cover, Amerisleep’s AS2 mattress excels in temperature regulation. I never woke up overheated or sweaty, even in the summer. The cover pleasantly reduces surface heat while you sleep, its cutting-edge materials excellently wicking away warmth and increasing airflow keeping the sleeper fresh all night.

The Refresh Cover, made from a specialized fabric designed to draw heat away from the body. Through enhanced energy transfer capabilities, this cover can keep the sleeping surface up to 7 degrees cooler over an 8-hour sleep period compared to a traditional polyester cover.

The infused minerals in the cover have properties that can absorb and dissipate heat more effectively. When these cooling minerals come in contact with body heat, they work to draw heat away from the body, keeping the surface of the fabric cooler. Essentially, it’s a natural way to help regulate temperature and make the sleeping surface feel cooler and more comfortable.

Underneath the cover lies the Bio-Pur® comfort layer foam. Constructed with an open-cell design, the structure allows increased airflow and breathability compared to traditional memory foam. The open cells allow heat to dissipate instead of building up within the material. These natural ingredients also tend to have better breathability and can dissipate heat more efficiently than an all-synthetic design.

As I discuss below, reviewers consistently praise the cooling properties of Bio-Pur®, with many hot sleepers finding relief from overheating.

The combination of the moisture-wicking abilities of the Refresh Cover and the airflow permitted by the Bio-Pur® layer proves highly effective at temperature regulation. By drawing heat away from the body and allowing it to dissipate, Amerisleep has engineered an exceptionally cool sleeping surface that caters to those wanting to stay cool while they sleep.

Truly, Amerisleep pulls out all stops to prevent heat retention. I never awoke drenched in sweat or needing to adjust to cool down, ensuring I stayed pleasantly cool even in a warm bedroom.

VI. Durability and Longevity

All Amerisleep mattresses, including the AS2, are handcrafted in the USA using quality, eco-friendly materials. Having mattresses made in the US is important for various reasons, including supporting local industries, ensuring adherence to rigorous safety and quality standards, and minimizing environmental impact through reduced transportation distances.

After personally testing this bed, I saw no immediate signs of poor durability. This mattress seems designed to last thanks to its sturdy construction. All foams felt dense and returned to form without hesitation while the cover and stitching appeared taut and reinforced.

A 20-year warranty on the AS2 protects against defects and impressions greater than an inch deep. The standard length of a mattress warranty is typically ten years, but Amerisleep goes above and beyond industry norms by offering a remarkably long warranty.

This extended coverage not only demonstrates the brand’s confidence in the durability of their mattresses but also provides customers with an extra layer of assurance. Amerisleep’s commitment to a two-decade warranty underscores their dedication to long-term customer satisfaction, assuring buyers that their investment is well-protected.

And when I looked through reviews, it seems I’m not the only one impressed by its structural integrity. Jaymi provided a positive review, describing the mattress as solid and how impressed they were by its durability and quality. David echoed this as well, calling the mattress a “good firm bed” and that it “seems durable.”

With the quality construction inside the mattress and its stellar protection policies, this bed should easily last over a decade.

VII. Potential Drawbacks

While Amerisleep’s AS2 impressed me in many areas during testing, it may not satisfy all preferences. As I mentioned, the medium-firm feel could be too rigid for petite people or those wanting extra pressure relief.

While many stomach, back, and combo sleepers will appreciate the AS2’s firmness, it could be unsuitable if you desire more plush softness and contouring sink-in. Side sleepers and anyone under 130 pounds might be happier with the softer AS3 model instead.

This model also stays at a typical 12” thickness, so couples wanting to reduce partner disturbance with a thicker design may need to consider Amerisleep’s 14” options instead, such as the Amerisleep AS5 Hybrid. Those searching for adequate back support with impressive cooling will love this Amerisleep AS2, however.

Lastly, as an all-foam mattress, there are no internal coils, thus hybrid mattress shoppers should check out alternative picks. If you prefer springier coils over dense foam, Amerisleep also offers the AS3 Hybrid to better match your priorities.

Amerisleep’s review section helpfully begins with a curated list of pros and cons, based upon recurring words in customer’s reviews. For the Amerisleep AS2, I saw that the most commonly cited drawbacks were “too hard” followed by the much less common “too soft,” “develops cavity,” and “squeaks.”

VIII. Trial Period, Warranty, Pricing and Sizes

I’m pleased Amerisleep offers customers a 100-night risk-free trial to truly evaluate if the AS2 works for you. In my experience reviewing and testing mattresses, this is in line with the standard industry norm of three or more months to test a mattress.

Being able to test a mattress is crucial because it allows individuals to assess firsthand how well the mattress aligns with their comfort preferences and sleeping needs, particularly when purchasing online mattresses. Testing provides a tangible experience, helping customers evaluate factors like firmness, support, and overall comfort.

If the Amerisleep AS2 is not the perfect match, they’ll arrange a full refund. Their customer service team has been highly reputable for handling the process promptly and hassle-free.

Amerisleep’s exceptional 20-year warranty also safeguards against defects like sagging greater than an inch. A mattress warranty is essential as it serves as a safeguard against potential defects or premature wear, providing consumers with confidence in their investment.

A warranty reflects the manufacturer’s commitment to the durability and quality of their product. A comprehensive warranty not only protects the buyer from unexpected issues but also offers peace of mind, ensuring that the mattress will maintain its performance over an extended period.

Amerisleep demonstrates their full confidence in the AS2 model by offering a warranty that’s ten years longer than the industry standard mattress warranty of 10 years.

Available in all standard mattress sizes from twin to split king, this range of options ensures a proper fit and ideal comfort no matter your sleep space size and personal needs. Carefully assessing your requirements helps select the ideal dimensions for your new AS2.

The AS2 is very reasonably priced compared to similar premium memory foam options. For example, it’s less than Saatva’s Loom & Leaf mattress, another high-quality medium-firm memory foam mattress, and only a little bit more expensive than the thinner Bear Original mattress.

While costing more than basic foam mattress options, such as the Vaya Mattress and other budget mattresses, I found the innovative construction and comforting night’s sleep worth the investment. Reviewers seem to agree with me, as most indicated they were “mid-range shoppers” followed by “budget shoppers,” according to the review section’s filter options.

Overall, the price tag seems to be in line with the average price point of a memory foam mattress in a box, and its innovative four-layer memory foam design with advanced cooling justifies the investment for many shoppers. Affordable payment plans can be arranged through Amerisleep’s financing partner if needed.

IX. Customer Reviews

I always survey reviews from verified customers to corroborate my own assessments. Scouring through customer experiences, the overwhelming majority of AS2 reviews are glowing 5-star appraisals. Many share stories of this mattress eliminating persistent back aches or chronic neck pain and finally getting restful sleep without discomfort.

As I mentioned earlier, the review section of Amerisleep starts by presenting a thoughtfully curated list of advantages and disadvantages, according to consumer feedback expressed through reviews. For the Amerisleep AS2, the top benefits were “good support,” “comfortable,” “holds shape,” “durable,” and “soft feel.”

One customer in particular claims the mattress “worked miracles” on their sciatica while several others report no more tossing and turning while being properly aligned.

Here are what more satisfied reviewers had to say:

  • Lesleybian highlights the unique comfort of the mattress, emphasizing how it’s only one she can sleep on without experiencing pain. A side sleeper dealing with serious back pain, Lesleybian notes she is “a big woman” who shares the bed with her 14-pound service dog. While her side of the mattress does have a slight impression from her body, she notes she still experiences 5-out-of-5 comfort.
  • Marcos praises the AS2 mattress as one of the best he has used, emphasizing its value. As a 65-year-old, he specifically appreciates the firmer feel of the mattress and appreciates that it maintains its shape well, distinguishing it from other mattresses he has owned in the past.

However, a minority of reviewers report issues from excessive firmness. One customer felt it insufficiently cushioned pressure points as a side sleeper.

Another noted that they woke up with lower back pain regularly, and this was particularly unwelcome because of their demanding job. “I am an operating room nurse and to have to wake up to excruciating pain every morning is out of the question.”

Yet another customer, Begie, expressed that the mattress was excellent for alleviating arthritis in the hips but lacked sufficient support for the back. Notably, though, Begie highlighted the excellent customer service received when exchanging for a higher-numbered and softer Amerisleep model.

Thus, it’s extremely important to remember that sleep position and preferred softness levels are key considerations before purchasing.

Some may also feel the mattress isn’t cool enough. For example, Bill switched from an older spring mattress to the AS2 and found it to be a “perfectly good mattress.” Despite his initial discomfort in the hips, which resolved after a few nights, the AS2 effectively alleviated middle back pain.

However, Bill mentioned that the AS2’s heat dissipation is worse than a spring bed, particularly noticeable during a heatwave in 2023. He did note this was possibly exacerbated by high humidity.

After analyzing customer experiences across various sites, I concluded most back and stomach sleepers should achieve restful slumber but those wanting ample cradling may need an alternative model tailored to their sleeping habits and body types.

X. Environmental Impact

From their substantiated materials to their streamlined production, Amerisleep makes ethical and sustainable choices to maintain ecological integrity. Amerisleep’s 360 environmental statement details how they are committed to developing sustainable plant-based foams, a zero-air emissions manufacturing process, and efficient consumer delivery.

As I mentioned earlier, their mattresses are made in the U.S., which keeps the environmental impact lower and in greater compliance with regulations and sustainability standards than a mattress made overseas.

I love that Amerisleep pursues eco-friendly mattresses and sustainability, like their plant-based foam production methods that partially substitute petroleum typically used in bedding with renewable castor oil. They also developed a highly efficient direct-to-consumer shipping model to reduce their carbon footprint.

With their packing and delivery system of boxed mattresses instead of mattresses laid falt in a truck, Amerisleep states they can ship 300 percent more mattresses per delivery. Using an eco-shipping method saves an average of 80% on fuel consumption.

As a bonus, you never have to worry about hazardous materials within their mattresses. All foams used meet CertiPUR-US® standards for minimal emissions and Amerisleep mattresses are fiberglass-free.

The certification ensures that the mattress is made without harmful chemicals, reducing the environmental impact. Additionally, CertiPUR®-certified foams are low in volatile organic compounds (VOCs), contributing to better indoor air quality and promoting a healthier environment

XI. Maintenance and Care

Amerisleep recommends safeguarding your investment using a breathable waterproof mattress protector. While optional, using a mattress protector can further maintain the AS2’s pristine condition. This optional protective layer shields against spills, stains, and other damage-causing accidents. Periodically vacuuming the mattress surface using a soft brush attachment also helps lift away dust and allergens.

A key advantage of the AS2 is it never requires flipping or rotating, preventing excess wear. However, be sure to pair it with a suitable foundation like Amerisleep’s adjustable base or a supportive frame with rigid center support and slats no more than 3 inches apart. Proper support maintains the AS2’s structure, comfort, and 20-year durability.

If you are planning to transport the mattress, carefully lift and carry it vertically to prevent potential tears or damage – preferably with a helper to distribute weight. And should indentation or materials issues arise despite normal use, Amerisleep’s customer service team can guide you through the warranty claim process to address defects.

By adding a mattress protector, using a solid frame, and moving the mattress with care, you can keep your AS2 looking and feeling pristine. Following these simple tips ensures it retains those straight A’s for support, pain relief, and peaceful slumber for the full 20 years.

Final Verdict – Score: 9/10

I rate the Amerisleep AS2 mattress a 9 out of 10 based on its commendable performance across my evaluation criteria. This high-quality cooling mattress delivers on comfort, support, durability, and beyond to earn my wholehearted recommendation.

Starting from the cover through the four ergonomic layers below, Amerisleep designed their AS2 model for cooling relief. I confirmed their claims, as innovative construction technology like the Bio-Pur® foam and breathable cover provide exceptional temperature regulation all night.

A perfect example of “hybrid” construction that successfully blends conforming memory foam with responsive transition layers for freedom of movement, the AS2 adapts rapidly to sleep position changes. Edge support and motion isolation also garner top scores, ensuring undisturbed rest.

Available at a fair price point for a premium mattress with 20-year coverage, Amerisleep offers tremendous value to buyers wanting long-lasting comfort. Supportive yet cushioning at a medium-firm feel, back and stomach sleepers should find ideal pressure relief and support for spinal alignment with excellent cooling. Side sleepers, however, may prefer a plusher option.

Earning stellar marks for cooling, responsiveness, quality materials, absence of motion transfer, extensive warranty, eco-conscious production, and rave customer feedback, the exceptional Amerisleep AS2 is worthy of a 9 out of 10 rating. I confidently recommend this mattress for hot or fidgety sleepers wanting pressure relief, a cooler night’s sleep, and lasting comfort night after night.
