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.

Conforming memory foam envelops your body and it gives you cradling comfort for a better night sleep. The open-celled structure of our foams are self-ventilating. Air is able to travel throughout the material and actually dissipate body heat.

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.
The HIVE® layer features hundreds of foam hexagons grouped into five comfort zones. Each zone is designed to provide extra cushion where you want it and support where you need it. That way your body gets the support it needs to stay properly aligned, so you can sleep your best.

The High Density Support Core (HD) gives your body the right support so you awaken refreshed. By eliminating counter pressure, blood flows freely throughout your body without harmful capillary compression and restriction caused by pressure points.

The HIVE® transition 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.
Amerisleep's Bio-Pur® material features an advanced-open cell design. This makes Bio-Pur® more breathable and responsive than memory foam, which will keep you cool and comfortable all night. Plus we make Bio-Pur® from partially plant-based sources using a zero-emission process. That means it's the most eco-friendly material of its kind.

Gel Infused Memory Foam
1" Gel Infused Cool Memory Foam for added pressure relief conformance and cooling
Total Body Support Core
8.5 Inches HD (High Density) Performance Core Support Base.

Bio-Pur® contours to your body to relieve pressure points and bounces back fast, so you won't feel "stuck" during the night.
Our HIVE® transition layer provides targeted support and pressure relief so you can sleep in perfect alignment. It gives your head, back, and legs more support, and your shoulders and hips more cushion.

Responsive Memory Foam
12 Inch thick design with 2.5" Premium Memory Foam layer for a relaxing hug and pressure point relief.

Refresh Cooling Cover
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 compared to a traditional 100% polyester cover. This scientifically engineered fabric uses minerals to help convert your natural body heat into far infrared energy. This type of energy increases blood circulation to help speed up muscle recovery and improve quality of sleep.

Luxurious Soft Breathable Cover
We selected our soothing fabric by hand to ensure its welcoming soft touch, flexibility and also perfectly contours to your body's shape. The removable and washable cover is designed to complement the conforming memory foam.
