Need Help Deciding?
For most sleepers, we recommend the Purple The Purple Mattress over the Amerisleep AS3. It scores higher in price-to-value and offers strong overall value at $1,399 (vs $1,749). 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 Purple The Purple Mattress: What Actually Differs
The Amerisleep AS3 is a memory foam build, while the Purple The Purple Mattress is a gel grid (plant-based_memory_foam vs gel-grid-foam) — that single difference drives most of the cooling, motion, and feel decisions below. The Amerisleep AS3 stands 12" tall versus 9.25" for the Purple The Purple Mattress — a 2.8" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Purple The Purple Mattress is the firmer of the two at 6.5/10 (medium-firm), and the Amerisleep AS3 sits at 5.5/10 (medium) — a meaningful enough gap that sleeper position and weight should drive the choice. On a Queen, the Purple The Purple Mattress runs $1,399 versus $1,749 for the Amerisleep AS3 — roughly $350 (20%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.

Both fall in the medium-firm zone back sleepers prefer (5.5/10 vs 6.5/10) — either works.
Firmer at 6.5/10 vs 5.5/10 — 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 5.5/10 vs 6.5/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
