Need Help Deciding?
For most sleepers, we recommend the Amerisleep AS1 over the Amerisleep AS2. It scores higher in cooling, motion isolation, pressure relief and delivers stronger overall value. The Amerisleep AS2 is the better choice only if you specifically prefer a softer, more plush feel.
Amerisleep AS1 vs Amerisleep AS2: What Actually Differs
The Amerisleep AS1 is a foam build, while the Amerisleep AS2 is a memory foam (memory-foam vs plant-based_memory_foam) — that single difference drives most of the cooling, motion, and feel decisions below. The Amerisleep AS2 stands 12" tall versus 10" for the Amerisleep AS1 — a 2.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Amerisleep AS1 is the firmer of the two at 8.5/10 (firm), and the Amerisleep AS2 sits at 6.5/10 (medium-firm) — a meaningful enough gap that sleeper position and weight should drive the choice. On a Queen, the Amerisleep AS1 runs $749 versus $1,049 for the Amerisleep AS2 — roughly $300 (29%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.
Which Is Better For Your Sleep Style?
Pressure-relief data not available for one or both mattresses — spec not available.
Firmness of 6.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 8.5/10).
Firmer at 8.5/10 vs 6.5/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.
Cooling rating not available for one or both mattresses — spec not available.
Durability and edge-support ratings not available — spec not available.
Softer at 6.5/10 vs 8.5/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Motion-isolation data not available for one or both mattresses — spec not available.
