Need Help Deciding?
For most sleepers, we recommend the Nolah Evolution over the Amerisleep AS5. It scores higher in cooling, pressure relief, edge support and offers strong overall value at $1,480 (vs $1,849). The Amerisleep AS5 is the better choice only if you specifically prefer a softer, more plush feel.
Amerisleep AS5 vs Nolah Evolution: What Actually Differs
The Amerisleep AS5 is a memory foam build, while the Nolah Evolution is a hybrid (plant-based_memory_foam vs foam-hybrid) — that single difference drives most of the cooling, motion, and feel decisions below. Profile-wise they're almost identical — the Amerisleep AS5 measures 14" and the Nolah Evolution measures 14", so neither will dictate your sheet depth or bed-frame compatibility. The Nolah Evolution is the firmer of the two at 6.5/10 (medium-firm), and the Amerisleep AS5 sits at 3.5/10 (medium-soft) — a meaningful enough gap that sleeper position and weight should drive the choice. On a Queen, the Nolah Evolution runs $1,480 versus $1,849 for the Amerisleep AS5 — roughly $369 (20%) 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?
Pressure-relief data not available for one or both mattresses — spec not available.
Firmness of 6.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 3.5/10).
Firmer at 6.5/10 vs 3.5/10 — 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 3.5/10 vs 6.5/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Motion-isolation data not available for one or both mattresses — spec not available.
