Need Help Deciding?
For most sleepers, we recommend the Nectar Premier Copper over the Amerisleep AS3. It scores higher in motion isolation, pressure relief, durability 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 Nectar Premier Copper: What Actually Differs
Both the Amerisleep AS3 and Nectar Premier Copper are memory foam mattresses, so the real differences come down to firmness tuning, performance ratings, and price rather than construction type. The Nectar Premier Copper 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 5.5/10 on the firmness scale — a medium-firm feel — so neither one is the answer if you need a dramatically different support level. On a Queen, the Nectar Premier Copper runs $1,599 versus $1,749 for the Amerisleep AS3 — roughly $150 (9%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about. Trial periods aren't symmetrical either: the Nectar Premier Copper 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?
Pressure-relief data not available for one or both mattresses — spec not available.
Firmness of 6/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 5.5/10).
Firmer at 6/10 vs 5.5/10 — 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 5.5/10 vs 6/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Motion-isolation data not available for one or both mattresses — spec not available.
