Need Help Deciding?
For most sleepers, we recommend the Bear Star Hybrid over the Amerisleep AS3. It scores higher in motion isolation, pressure relief, edge support and delivers stronger overall value. The Amerisleep AS3 is the better choice only if you have a strong preference for that brand's specific feel or design.
Amerisleep AS3 vs Bear Star Hybrid: What Actually Differs
The Amerisleep AS3 is a memory foam build, while the Bear Star Hybrid is a hybrid — that single difference drives most of the cooling, motion, and feel decisions below. Profile-wise they're almost identical — the Amerisleep AS3 measures 12" and the Bear Star Hybrid measures 12", so neither will dictate your sheet depth or bed-frame compatibility. Both sit at roughly 5.5/10 on the firmness scale — a medium feel — so neither one is the answer if you need a dramatically different support level. On a Queen, the Bear Star Hybrid runs $1,043 versus $1,749 for the Amerisleep AS3 — roughly $706 (40%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.

Firmer at 5.5/10 vs 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 5/10 vs 5.5/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
