Need Help Deciding?
For most sleepers, we recommend the Amerisleep AS5 over the Purple Mattress. It scores higher in cooling, motion isolation and delivers stronger overall value. The Purple Mattress is the better choice only if you specifically prefer a firmer, more supportive feel.
Amerisleep AS5 vs Purple Mattress: What Actually Differs
The Amerisleep AS5 is a memory foam build, while the Purple Mattress is a gel grid — that single difference drives most of the cooling, motion, and feel decisions below. The Amerisleep AS5 stands 14" tall versus 9.5" for the Purple Mattress — a 4.5" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Purple Mattress is the firmer of the two at 6.5/10 (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 motion isolation: the Amerisleep AS5 rates noticeably higher than the Purple Mattress, which is the deciding factor if that dimension is high on your list. On a Queen, the Purple Mattress runs $1,399 versus $1,599 for the Amerisleep AS5 — roughly $200 (13%) 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?
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 6.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 4/10).
Firmer at 6.5/10 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.
Durability and edge-support ratings are equivalent — either holds up.
Softer at 4/10 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.
