Amerisleep Mattresses, Ranked

Amerisleep's line runs AS1 (firmest) through AS5 (softest); the AS3 we track is the balanced middle child and the brand's best seller. Its Bio-Pur foam is partially plant-based and more open-celled than conventional memory foam, which makes it quicker to respond and noticeably cooler.

A 20-year warranty doubles the category standard and signals real confidence in the foam's durability. The AS3's full Value Score breakdown is below.
