Product description from Amerisleep:

The AS4 is our medium-soft mattress. It’s great for side sleepers, and anyone who likes more cushioning while they’re in bed. We combine our proprietary, cooling Bio-Pur foam and Affinity with SMT comfort foam layers to create a soft but responsive feel that relieves pressure points and makes you feel like you’re floating. Plus the high-performance Celliant cover is made with thermo-reactive yarn to safely turn body heat into infrared.

HIGH-PERFORMANCE CELLIANT COVER
Celliant® is an advanced fabric made with 13 thermo-reactive minerals that helps improve the performance of the mattress.

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.

ENHANCED "FEELS-LIKE-YOU'RE-FLOATING" LAYER
The Affinity layer with Surface Modification Technology (SMT) is our ergonomic transition foam. It has “zones” that provide extra pressure relief in key areas like the shoulders and lower back, along with precision-cut channels that carry away even more heat and moisture. It’s enough to make you feel like 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 AS4 became the new name for the mattress that was previously called the Amerisleep Colonial.
