Amerisleep AS3 mattress review in brief
The Amerisleep AS3 Hybrid mattress is a medium firmness mattress that's particularly suited to side sleepers, whose pressure points will be cushioned by the slightly softer foam. Like many of the best mattresses, this is a hybrid model meaning it's made from a combination of foams and coils. But the AS3 Hybrid uses Amerisleep's proprietary Bio-Pur foam, which does an excellent job of keeping sleepers cool at night. Those who sleep hot should enjoy this mattress, which remains nice and breathable throughout the night.
