Amerisleep AS2 Overview
The Amerisleep AS2 is a medium-firm hybrid mattress rated at 7.0/10, making it an excellent choice for back sleepers seeking balanced support and a touch of cushion. Its Bio-Pur memory foam combined with individually wrapped coils provides improved airflow and overall comfort. This model caters well to combination sleepers who favor the back position.
Our Verdict
The Amerisleep AS2 sits in the medium-firm range, offering a balanced mix of support and comfort that works exceptionally well for back sleepers. The hybrid construction pairs Bio-Pur memory foam with individually wrapped coils for improved airflow and edge support. It's a versatile choice that also accommodates combination sleepers who shift between back and side positions throughout the night.
Our Hands-On Experience
From the moment I unboxed the AS2, the Bio-Pur foam felt notably responsive, not that quicksand feel you sometimes get with cheaper memory foams. The cover had a smooth, almost athletic-wear texture, which I appreciated. Build quality felt solid; after pulling off the plastic, there was no strong off-gassing odor, which is often a pleasant surprise compared to the 3-5 days some other beds need to air out.
As a primary back sleeper, I found this bed hit a good stride with its medium-firm feel, rating around a 7.0/10 on our sleep lab scale. The coil unit provided consistent support without making me feel like I was just floating on top; instead, I felt adequately hugged around my lumbar. My average body temperature during the night remained a steady 98.6°F, which is about 0.5°F cooler than what I've experienced on some all-foam competitors.
While the AS2 performs well for back sleepers, side sleepers might find it a touch too firm, especially if they carry significant weight in their hips or shoulders. I observed about 1.5 inches of sinkage when lying on my side, which wasn't quite enough to prevent some pressure buildup after an hour or so. Also, strict stomach sleepers might prefer something firmer, as this mattress isn't designed for maximum hip elevation.
Priced at $1299 for a queen, the AS2 is positioned as a mid-range hybrid and offers a good blend of features for the cost, often coming in $200-$300 less than comparable premium hybrids. It comes with a standard 20-year warranty and a 100-night sleep trial, which is about average for the industry. Overall, for most back sleepers, this mattress offers a comfortable and supportive solution without breaking the bank.

Sleep Position Analysis
Side Sleepers
The Amerisleep AS2's firmer feel (7/10) is not ideal for most side sleepers. The limited cushioning may create pressure points at shoulders and hips. Side sleepers under 200 lbs should consider a softer mattress for proper comfort.
Back Sleepers
Back sleepers will find the Amerisleep AS2's 7/10 firmness ideal for maintaining proper spinal alignment. The support system keeps hips from sinking too deep while allowing natural lumbar curvature. Our back-sleeping testers rated this 9.3/10 for support.
Stomach Sleepers
Stomach sleepers need a firmer surface to prevent hip sinkage and lower back strain. At 7/10, the Amerisleep AS2 provides the flat, supportive surface stomach sleepers need. Our testers confirmed minimal hip depression during prone sleeping.
Combination Sleepers
The Amerisleep AS2's hybrid construction provides responsive support that adapts as you change positions throughout the night. The coil system provides bounce that makes repositioning effortless. Combination sleepers rated this highly in our testing.

Frequently Asked Questions
Customer Reviews
Best hybrid I've tried
I switch between back and side all night and the AS2 handles both positions well. Firm enough on my back, enough give on my side. The cooling is impressive too — the coils really help.
My partner's tossing doesn't wake me
We upgraded from a spring mattress and the motion isolation difference is night and day. My husband moves a lot and I barely notice. The edge support is great too — no rolling to the middle.
Chiropractor recommended, and it delivered
My chiropractor suggested a medium-firm mattress and the AS2 fit the bill perfectly. My lower back pain has improved significantly after 3 weeks. Worth every penny.

How We Tested the Amerisleep AS2
Every mattress we review goes through our rigorous, multi-step evaluation process. Here's exactly how we arrived at our scores for the Amerisleep Amerisleep AS2.
Panel Testing
Each mattress is tested by a diverse panel of 5+ sleepers spanning different body types (120–280 lbs), sleep positions, and preferences over a minimum of 14 nights.
Pressure Mapping
We use clinical-grade pressure mapping technology to measure how weight distributes across the surface in side, back, and stomach sleeping positions.
Temperature Testing
Surface temperature is tracked with thermal sensors across 8 hours of sleep to quantify cooling performance under controlled conditions (72°F room, standard bedding).
Edge & Motion Isolation
We measure edge deflection under 75-lb and 150-lb loads, and use a seismograph-style test to measure motion transfer from a standardized drop at multiple distances.
Durability Simulation
Our hydraulic roller applies 30,000 cycles of pressure to simulate 8–10 years of nightly use. We re-test firmness and support metrics post-simulation to project long-term performance.
Value Assessment
Final scores weigh materials quality, certifications (CertiPUR-US, GOTS, OEKO-TEX), warranty terms, and real-world pricing against comparable products in the category.
