The AS2 is our medium-firm mattress, and it’s our most popular with back and stomach sleepers. It’s thicker than the AS1 and contains a transition foam layer, giving it slightly more cushion. We blend our proprietary Bio-Pur™, Affinity with SMT, and Bio-Core™ foam layers to provide comfortable but stable support. Plus the Celliant® cover is made with thermoreactive yarn to safely turn body heat into infrared. You'll love it, guaranteed.

We've got it all covered
And put just as much thought into what's inside.
Your mattress will be wrapped in a Celliant-infused cover. Celliant® is a thermo-reactive thread that has been clinically proven to help people fall asleep 15 minutes faster on average. It does this by using your natural body heat and recycling it into infrared light. This healing energy will help you wake up with more energy and less aches and pains.
Our large, open-cell memory foam will conform to your body while keeping you cool as you sleep. Since Bio-Pur™ is made with plant-based materials, we have lessened our reliance on petroleum. Bio-Pur™ excels at keeping you relaxed as you fall asleep.
The Bio-Core™ base layer provides solid support designed to preserve natural alignment without contributing to pressure points. Amerisleep's Bio-Core™ is composed of high-density material for comfort that lasts.
Sleep that's got your back.
And side. And stomach.
