Need Help Deciding?
For most sleepers, we recommend the Amerisleep AS5 over the Nectar Premier Copper. It scores higher in cooling and delivers stronger overall value. The Nectar Premier Copper is the better choice only if you want more time to decide (365-night trial vs 100 nights).
Amerisleep AS5 vs Nectar Premier Copper: What Actually Differs
Both the Amerisleep AS5 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 Amerisleep AS5 stands 14" tall versus 13" for the Nectar Premier Copper — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Nectar Premier Copper is the firmer of the two at 6/10 (medium-firm), and the Amerisleep AS5 sits at 4/10 (medium-soft) — a meaningful enough gap that sleeper position and weight should drive the choice. The single largest performance gap is in long-term durability: the Nectar Premier Copper rates noticeably higher than the Amerisleep AS5, which is the deciding factor if that dimension is high on your list. Queen pricing lands within $1 of each other ($1,599 vs $1,599), so price is essentially neutral — pick on feel and features rather than budget. Trial periods aren't symmetrical either: the Nectar Premier Copper 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?
Both rate the same for pressure relief — choose on firmness instead (side sleepers usually prefer the softer of the two: Amerisleep AS5 at 4/10).
Firmness of 6/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 4/10).
Firmer at 6/10 vs 4/10 — 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.
better long-term durability — the two specs heavier sleepers should weight most.
Softer at 4/10 vs 6/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Motion isolation rated the same on both — neither has a transfer-disturbance edge.
