Need Help Deciding?
For most sleepers, we recommend the Birch Natural Mattress over the Amerisleep AS3. It scores higher in pressure relief, edge support, durability and delivers stronger overall value. 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 Birch Natural Mattress: What Actually Differs
The Amerisleep AS3 is a memory foam build, while the Birch Natural Mattress is a hybrid — that single difference drives most of the cooling, motion, and feel decisions below. The Amerisleep AS3 stands 12" tall versus 11" for the Birch Natural Mattress — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Birch Natural Mattress is the firmer of the two at 7/10 (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 Birch Natural Mattress runs $1,499 versus $1,749 for the Amerisleep AS3 — roughly $250 (14%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.

Firmness of 5.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 7/10).
Firmer at 7/10 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 7/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
