Need Help Deciding?
For most sleepers, we recommend the Amerisleep AS2 over the Amerisleep AS1. It has a verified current Queen price, while the other mattress was marked unavailable in Queen at the latest check. The Amerisleep AS1 is the better choice only if you have a strong preference for that brand's specific feel or design.
Amerisleep AS1 vs Amerisleep AS2: What Actually Differs
The Amerisleep AS1 is a foam build, while the Amerisleep AS2 is a memory foam — that construction 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. Their firmness is close but not identical: the Amerisleep AS1 is 7/10 and the Amerisleep AS2 is 6.5/10. Both land near a medium-firm feel, so the half-point difference is less decisive than their construction and pressure response. The single largest performance gap is in cooling: the Amerisleep AS2 rates noticeably higher than the Amerisleep AS1, which is the deciding factor if that dimension is high on your list.
Which Is Better For Your Sleep Style?
Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.
Medium-Firm includes the option closest to a balanced medium feel for back sleepers (vs Firm).
Firm includes the firmer published option (vs Medium-Firm), which may better suit shoppers who prefer more surface support.
Stronger cooling rating, which matters most for sleepers who run hot or live in warm climates.
better long-term durability — the two specs heavier sleepers should weigh most.
Medium-Firm includes the softer published option (vs Firm), which can make contouring easier for lighter sleepers.
Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
Amerisleep AS1
Strengths
- ✓The simple 2-inch comfort layer over an 8-inch support core creates a flatter, lower-sink choice for back and stomach sleepers
- ✓At the checked prices, AS1 is Amerisleep's least expensive current mattress and costs $200 less than AS2 in matching listed sizes
- ✓The all-foam build should limit partner disturbance better than a springier hybrid, although SleepRanked has not measured motion transfer
- ✓Twin XL, Cal King, and Split King were immediately purchasable in the current first-party variant data
Considerations
- —Amerisleep does not recommend this Firm model for side sleepers because the surface may not cushion the shoulder and hip enough
- —There is no HIVE targeted-support layer, no dedicated reinforced edge, and no AS1 hybrid version
- —Twin, Full, Queen, and King were temporarily sold out when the current exact product was verified
Amerisleep AS2
Strengths
- ✓The five-zone HIVE transition changes the response beneath different body areas; Amerisleep describes added support under the head, back, and legs with extra cushion under the shoulders and hips
- ✓Two inches of open-cell Bio-Pur memory foam provide a thinner, firmer comfort layer than AS3 while responding faster than conventional slow-sink memory foam according to Amerisleep
- ✓AS2 and AS3 share a 12-inch three-layer material family, but AS2 uses a 2/3/7-inch medium-firm stack while AS3 shifts to a 3/2/7-inch medium stack for more surface contour
- ✓The all-foam build avoids connected coil movement, a construction advantage for couples who prioritize motion isolation over spring response
Considerations
- —Most strict side sleepers should compare Medium AS3 or Soft AS5 because Amerisleep chiefly positions Medium-Firm AS2 for back sleepers and petite stomach sleepers
- —The all-foam support core lacks the perimeter reinforcement and through-bed airflow of a pocket-coil hybrid
- —Amerisleep's seven-degree cover comparison, cooling language, pressure-relief claims, and back-pain positioning are manufacturer or endorsement evidence; SleepRanked has not independently reproduced those outcomes
