I am Dr. Colleen Ehrnstrom, a clinical psychologist holding a license for more than two decades, with a focus on acceptance and commitment therapy (ACT) and cognitive behavioral therapy (CBT). This detailed assessment of the Amerisleep AS3 mattress is a collaborative effort with Dr. Burns, an esteemed sleep specialist known for his profound knowledge in sleep disorders and therapeutic approaches.

With my background in sleep psychology and as a medium-weight individual who predominantly sleeps on my back and side, I have personally evaluated the Amerisleep AS3 mattress for a period of two months.

Dr. Burns, who is also a part of eachnight.com’s panel of expert reviewers, brings his credentials as a licensed chiropractor and certified sleep coach, accredited by the Spencer Institute, to our joint analysis.

Our goal is to deliver a thorough, expert-driven analysis of the AS3’s performance for various types of sleepers.

Unboxing, Setup and First Impressions

I ordered a queen size AS3 online which arrived vacuum-sealed in a compact box. Unboxing took just a few minutes – I cut open the packaging, watched the rolled mattress quickly expand to its full 12-inch thickness, then placed it on my bed frame. 

There was a very faint new mattress smell at first which dissipated by the next day. I noticed no off-gassing or other odors during setup or testing earning it a commendable rating of 5 out of 5 (with 5 being no smell and 1 being a strong smell). Its sleek design and plush yet supportive surface immediately caught my attention, creating a positive first impression.

Thoughtful Construction for Durability and Support

Examining the layers, I could see high-quality foams and thoughtful construction designed to provide comfort and support exactly where needed. That’s one of the reasons, AS3 has made it to our list of the best mattresses.

The AS3 has a soft, breathable cover made from a fiber blend, similar to Celliant, with high energy transfer capabilities. Below that is 3 inches of Bio-Pur memory foam that cushioned my body’s pressure points while staying resilient. Amerisleep says they have revolutionized traditional memory foam

The 2-inch Affinity transition layer is zoned with softer foam under the shoulders and firmer foam under the hips, which helped keep my spine aligned.

“The HIVE transition layer […] gives your body targeted support to ease tension and help you sleep in perfect alignment,” says Dr. Jordan Burns. This transition layer is crucial for maintaining spinal alignment and distributing body weight evenly, relying on specialized support zones created by careful cutouts in the foams for greater flexibility.

Finally, the thick 7-inch base foam reinforced the entire mattress so it stayed sturdy night after night.

Despite my above-average weight, the mattress showed no signs of sagging or impressions during my 2 months of testing. The quality and durability exceeded my expectations. I was thoroughly impressed and couldn’t help but give it a perfect rating of 5 out of 5 for its material and construction.

Balanced Medium Firmness for Comfort and Support

I would rate the AS3 around a 6 on the 10 point firmness scale. Lying down, I experienced noticeable contouring and cushioning comfort while still feeling properly supported.

The foams adapted to my body shape for pressure relief while keeping my spine on an even plane. Changing positions and getting in/out of bed was easy thanks to the responsive materials. I would say that the support and comfort offered by the AS3 mattress are among its key benefits

“As a chiropractor, I noticed the great support this mattress provides and definitely can confirm the claims on this layer are warranted,” Dr. Jordan Burns observes. This professional endorsement reinforces the mattress’s capability to provide optimal spinal support.

However, I did notice that the edge support fell slightly short, garnering a rating of 2 out of 5. That said, I’ve found this to be typical of foam mattresses. As I discussed in my Amerisleep AS3 Hybrid review, I found that model had more supportive edges due to its pocketed spring core.

Overall, its medium firmness struck the perfect balance between cozy comfort and sturdy support.

Consistent Support and Comfort in All Sleeping Positions

I tested the AS3 in my preferred back and side sleeping positions. My spine stayed properly aligned with no sinking around the hips. There was great edge support and sturdy stability across the entire mattress.

Despite my weight, I did not sink excessively into the mattress or feel like I was “in” rather than “on” it. The support and comfort remained consistent over 60 nights and in all sleeping positions. However, I did notice that the edge support fell slightly short, garnering a rating of 2 out of 5. That said, I’ve found this to be typical of foam mattresses.

Stayed Cool Through Warm Summer Nights

I tend to sleep hot, especially on all-foam beds, but this wasn’t an issue on the AS3. The open-cell Bio-Pur foam allowed constant airflow and moisture wicking to help me sleep cool, even on hot 95-degree summer nights.

I stayed comfortably cool without needing extra blankets or waking up in sweats like I did on my previous mattress. The AS3 exceeded my expectations for temperature regulation.

One of the standout features of the AS3 mattress is its cooling technology, as my colleague Dr. Jordan Burns agreed.

“The Refresh Cooling cover […] uses minerals to help convert your natural body heat into far-infrared energy, increasing blood circulation to help speed up muscle recovery and improve quality of sleep,” explains Dr. Burns. This innovative approach not only keeps the surface cool but also aids in better sleep health.

With a well-designed airflow system, this mattress earned a perfect rating of 5 out of 5 for its ability to maintain a comfortably cool sleep environment.

Minimal Motion Transfer

The AS3 isolated motion extremely well. I barely noticed movements when my partner changed positions or got in/out of bed at night. This helps prevent sleep disruptions for couples.

The responsive foams also rebounded quickly when I changed positions, so I never felt “stuck” in an imprint.

Recommendations for Shoppers After 2 Months of Testing

After sleeping on the Amerisleep AS3 for over 60 nights, I recommend it for average weight and heavy sleepers, plus back and stomach sleepers looking for a responsive, cooling memory foam mattress.

Side sleepers under 130 pounds may prefer something softer, but I encourage lighter folks to still try it, since the zoned construction provides support exactly where needed.

Value for Money

Now, let’s talk about value for money. The AS3 mattress offers exceptional bang for your buck. With different price ranges and sizes available, it caters to various budgets and preferences. Comparing it to other mattresses in the market, I wholeheartedly believe the AS3 is a worthwhile investment. It provides a high-quality, restorative sleep experience that simply cannot be overlooked.
