Need Help Deciding?
For most sleepers, we recommend the Cocoon by Sealy Chill Hybrid over the Amerisleep AS3. Our catalog rates it higher for edge support, durability; check current linked-seller prices and terms before deciding on 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 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 — that construction 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. Their firmness is close but not identical: the Amerisleep AS3 is 5/10 and the Cocoon by Sealy Chill Hybrid is 5.5/10. Both land near a medium feel, so the half-point difference is less decisive than their construction and pressure response. 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.
Which Is Better For Your Sleep Style?
Both rate the same for pressure relief — choose on firmness instead (side sleepers usually prefer the softer of the two: Amerisleep AS3 at 5/10).
Medium includes the option closest to a balanced medium feel for back sleepers (vs Medium).
Medium includes the firmer published option (vs Medium), which may better suit shoppers who prefer more surface support.
Cooling rated the same on both — neither has a heat-management edge in our spec data.
better long-term durability and stronger perimeter / edge support — the two specs heavier sleepers should weigh most.
Medium includes the softer published option (vs Medium), 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 AS3
Strengths
- ✓Three inches of Bio-Pur and two inches of HIVE reverse AS2's 2/3-inch comfort-to-transition ratio, giving AS3 more surface contour while keeping the same 12-inch height and seven-inch Bio-Core base
- ✓The five-zone HIVE cuts provide firmer response beneath the head, back, and legs and more give beneath the shoulders and hips according to Amerisleep's current construction description
- ✓Choose AS3 Foam over AS3 Hybrid for quieter, steadier all-foam contour and the lower current catalog price; choose Hybrid for spring response, support-core airflow, and a stronger perimeter
- ✓The solid-foam support core avoids connected coil movement, a practical construction advantage for couples who prioritize motion isolation over bounce
Considerations
- —Strict stomach sleepers and many sleepers over 230 pounds should compare the medium-firm AS2 or coil-supported AS3 Hybrid before choosing this medium foam design
- —All-foam AS3 has less perimeter reinforcement and through-bed airflow than AS3 Hybrid's eight-inch zoned pocketed-coil core
- —Amerisleep's seven-degree Refresh comparison, cooling, recovery, circulation, alignment, pressure, pain, motion, edge, and durability statements are manufacturer or construction evidence rather than SleepRanked lab results
Cocoon by Sealy Chill Hybrid
Strengths
- ✓Coils add easier movement and more bounce than the memory-foam model
- ✓Reinforced perimeter for edge support
- ✓Bolsa coils add airflow beneath the same cool-to-touch cover
- ✓Medium feel with pressure-relieving Perfect Fit Memory Foam
Considerations
- —Costs more than the all-foam Chill at every sold size
- —Motion isolation is naturally less absolute than the all-foam model
- —Country of manufacture is not disclosed
