Amerisleep AS3

The AS3 is our most versatile mattress. It evenly blends support and softness, so it’s great for people who change positions as they sleep and couples with different sleep styles. It’s also our most popular mattress overall. We combine our proprietary Bio-Pur and Affinity with SMT comfort layers to create a soft but responsive feel that relieves pressure points and makes you feel like you’re floating, and with the heat-wicking Refresh Cover you'll sleep up to 7 degrees cooler throughout the night.

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.

"FEELS-LIKE-YOU'RE-FLOATING" LAYER
The affinity transition layer is soft and responsive. It reacts to your body position to evenly support your weight and can help relieve pressure points, so it feels as if you’re weightlessly resting on a cloud.

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 AS3 became the new name for the mattress that was previously called the Amerisleep Liberty.
