Need Help Deciding?
For most sleepers, we recommend the Nectar Premier over the Amerisleep AS3. It scores higher in motion isolation, pressure relief and delivers stronger overall value. The Amerisleep AS3 is the better choice only if you sleep hot and cooling is your top priority.
Amerisleep AS3 vs Nectar Premier: What Actually Differs
Both the Amerisleep AS3 and Nectar Premier are memory foam mattresses, so the real differences come down to firmness tuning, performance ratings, and price rather than construction type. The Nectar Premier stands 13" tall versus 12" for the Amerisleep AS3 — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. Both sit at roughly 6/10 on the firmness scale — a medium-firm 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 Nectar Premier rates noticeably higher than the Amerisleep AS3, which is the deciding factor if that dimension is high on your list. Queen pricing lands within $50 of each other ($999 vs $949), so price is essentially neutral — pick on feel and features rather than budget. Trial periods aren't symmetrical either: the Nectar Premier ships with a 365-night sleep trial versus 100 nights for the Amerisleep AS3, giving you a longer in-home runway to send it back if the feel doesn't land.
Which Is Better For Your Sleep Style?
Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.
Both fall in the medium-firm zone back sleepers prefer (6/10 vs 6/10) — either works.
Effectively the same firmness (6/10 vs 6/10). Stomach sleepers generally want 7+/10 — neither is ideal if both rate lower.
Cooling rating not available for one or both mattresses — spec not available.
Durability and edge-support ratings are equivalent — either holds up.
Same firmness on both, but stronger pressure relief — lighter sleepers don't sink in as much and benefit from the more contouring of the two.
Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
