Need Help Deciding?
For most sleepers, we recommend the Leesa Original over the Amerisleep AS3. It delivers a better overall package. 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 Leesa Original: What Actually Differs
Both the Amerisleep AS3 and Leesa Original are memory foam mattresses, so the real differences come down to firmness tuning, performance ratings, and price rather than construction type. The Amerisleep AS3 stands 12" tall versus 11" for the Leesa Original — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. Both sit at roughly 6/10 on the firmness scale — a medium-firm feel — so neither one is the answer if you need a dramatically different support level. Queen pricing lands within $1 of each other ($999 vs $999), so price is essentially neutral — pick on feel and features rather than budget.
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: Leesa Original at 6/10).
Both fall in the medium-firm zone back sleepers prefer (6/10 vs 6/10) — either works.
Effectively the same firmness (6/10 vs 6/10). Stomach sleepers generally want 7+/10 — neither is ideal if both rate lower.
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.
Both have similar firmness and pressure-relief profile — either works.
Motion isolation rated the same on both — neither has a transfer-disturbance edge.
