Need Help Deciding?
For most sleepers, we recommend the Cocoon by Sealy Chill Hybrid over the Amerisleep AS3. It scores higher in edge support, durability while both are currently $1,149 for Queen. 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 Cocoon by Sealy Chill Hybrid: What Actually Differs
The Amerisleep AS3 is a memory foam build, while the Cocoon by Sealy Chill Hybrid is a hybrid (Plant Based Memory Foam vs Foam 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 Cocoon by Sealy Chill 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. The single largest performance gap is in motion isolation: the Amerisleep AS3 rates noticeably higher than the Cocoon by Sealy Chill Hybrid, which is the deciding factor if that dimension is high on your list. Queen pricing lands within $1 of each other ($1,149 vs $1,149), so price is essentially neutral — pick on feel and features rather than budget.
