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?

Side sleepers
Either works

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).

Back sleepers
Either works

Both fall in the medium-firm zone back sleepers prefer (6/10 vs 6/10) — either works.

Stomach sleepers
Either works

Effectively the same firmness (6/10 vs 6/10). Stomach sleepers generally want 7+/10 — neither is ideal if both rate lower.

Hot sleepers
Either works

Cooling rated the same on both — neither has a heat-management edge in our spec data.

Heavier sleepers (230+ lb)
Either works

Durability and edge-support ratings are equivalent — either holds up.

Lighter sleepers (under 150 lb)
Either works

Both have similar firmness and pressure-relief profile — either works.

Couples / light sleepers
Either works

Motion isolation rated the same on both — neither has a transfer-disturbance edge.
