Need Help Deciding?
For most sleepers, we recommend the Nectar Classic over the Amerisleep AS3. It scores higher in motion isolation, price-to-value 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 Classic: What Actually Differs
Both the Amerisleep AS3 and Nectar Classic are memory foam mattresses, so the real differences come down to firmness tuning, performance ratings, and price rather than construction type. Profile-wise they're almost identical — the Amerisleep AS3 measures 12" and the Nectar Classic measures 12", so neither will dictate your sheet depth or bed-frame compatibility. 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 Classic rates noticeably higher than the Amerisleep AS3, which is the deciding factor if that dimension is high on your list. On a Queen, the Nectar Classic runs $649 versus $999 for the Amerisleep AS3 — roughly $350 (35%) 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 Classic 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?
Both rate the same for pressure relief — choose on firmness instead (side sleepers usually prefer the softer of the two: Amerisleep AS3 at 6/10).
Firmness of 6/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 6.5/10).
Firmer at 6.5/10 vs 6/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.
Cooling rated the same on both — neither has a heat-management edge in our spec data.
Durability and edge-support ratings are equivalent — either holds up.
Softer at 6/10 vs 6.5/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
