Need Help Deciding?
For most sleepers, we recommend the Amerisleep AS5 over the Serta iComfort Aveda 12". It scores higher in pressure relief and delivers stronger overall value. The Serta iComfort Aveda 12" is the better choice only if you have a strong preference for that brand's specific feel or design.
Amerisleep AS5 vs Serta iComfort Aveda 12": What Actually Differs
Both the Amerisleep AS5 and Serta iComfort Aveda 12" 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 12" for the Serta iComfort Aveda 12" — a 2.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Serta iComfort Aveda 12" is the firmer of the two at 5.5/10 (medium), 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 pressure relief: the Amerisleep AS5 rates noticeably higher than the Serta iComfort Aveda 12", which is the deciding factor if that dimension is high on your list. On a Queen, the Serta iComfort Aveda 12" runs $1,499 versus $1,599 for the Amerisleep AS5 — roughly $100 (6%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.
Which Is Better For Your Sleep Style?
Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.
Firmness of 5.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 4/10).
Firmer at 5.5/10 vs 4/10 — 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 4/10 vs 5.5/10 — 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.
