Buy Amerisleep
The Amerisleep AS3 mattress is a versatile combination foam mattress known for its comfort, support, and pressure relief. It features three layers of foam, including a breathable Bio-Pur foam top layer, a transition poly foam layer, and a high-density poly foam base. The mattress offers good edge support, excellent motion isolation, and cooling properties. It is ideal for combination sleepers and those seeking a balanced feel of springs and foam. The AS3 comes with a 20-year warranty and a 100-night trial period. While it has received positive feedback for comfort and support, some users have reported issues with firmness and premature sagging.
