Mattress Construction

Materials Overview Three layer construction:
  • Bio-Pur™ foam
  • Ergonomic transition foam with Surface Modification Technology (SMT)
  • Bio-Core™ foam support layer
  • Celliant® cover.
Comfort Info Traditional memory foam is made from dense material, so it traps your body heat and can make you sweaty and uncomfortable while you're in bed - and who can sleep like that?
We developed our foam with an enhanced "open cell structure", which means there is more air space between the foam particles. That space wicks away heat while you sleep, and can keep you cooler and more comfortable.
Support Info 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.
Comfort Specs The Affinity layer has 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.
Our Bio-Pur™ foam is five times more breathable than traditional memory foam, because of its advanced open-cell structure. It wicks away heat while you sleep and can help keep you cool and comfortable.
Support Specs 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.
Fabric Specs High-Performance Celliant® Cover
Amerisleep is officially licensed to use Celliant® in our covers. This advanced fabric combines 13 minerals into thermoreactive yarn that converts body heat into infrared.
