Need Help Deciding?
For most sleepers, we recommend the Nectar Premier over the Amerisleep AS5. It scores higher in cooling, motion isolation, pressure relief and delivers stronger overall value. The Amerisleep AS5 is the better choice only if you specifically prefer a softer, more plush feel.
Amerisleep AS5 vs Nectar Premier: What Actually Differs
Both the Amerisleep AS5 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 Amerisleep AS5 stands 14" tall versus 13" for the Nectar Premier — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Nectar Premier is the firmer of the two at 6/10 (medium-firm), and the Amerisleep AS5 sits at 3.5/10 (medium-soft) — a meaningful enough gap that sleeper position and weight should drive the choice. On a Queen, the Nectar Premier runs $549 versus $1,849 for the Amerisleep AS5 — roughly $1,300 (70%) 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 ships with a 365-night sleep trial versus 100 nights for the Amerisleep AS5, 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 3.5/10).
Firmer at 6/10 vs 3.5/10 — 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 3.5/10 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.
