Amerisleep AS1

The AS1 is our firmest mattress, and it’s best for back and stomach sleepers who like extra support. We blend our proprietary Bio-Pur and Bio-Core foam layers to provide comfortable but stable cushioning, and the Celliant cover is made with thermo-reactive yarn to safely turn body heat into infrared. 

COOLER AND MORE BREATHABLE
The surface you sleep on is incredibly important to your comfort. That’s why we developed the Refresh Cover for our mattresses. Because it’s made from a fiber with extremely high energy transfer capabilities, the Refresh Cover draws heat from your skin for a delightfully cool-to-the-touch feel. On average, your sleeping surface will stay 7 degrees cooler over an eight-hour night of rest.

EXTRA-BREATHABLE COOLING LAYER
Our Bio-Pur foam is five times more breathable than traditional memory foam, because of it’s advanced open-cell structure. It wicks away heat while you sleep and can help keep you cool and comfortable.

SAG-FREE & ECO-FRIENDLY SUPPORT
Our Bio-Core foam support layer won't sag even after decades of use. And, like our Bio-Pur foam, it’s partially made from plants instead of petroleum so it’s eco-friendly.

* In 2017 Amerisleep changed their model names, at which time the Amerisleep AS1 became the new name for the mattress that was previously called the Amerisleep Americana.
