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.*

Plus, our plant-based Bio-Pur material keeps you cool all night. Its open-cell design allows more air to circulate than traditional foam — and more airflow means cooler sleep, less sweating, and no more tossing and turning.

Along with keeping you cool, the Refresh Cover also supports improved daily performance and energy. This scientifically engineered fabric uses minerals to help convert your natural body heat into far infrared energy.

Why far infrared? This type of energy increases blood circulation to help speed up muscle recovery and improve quality of sleep. Plus, according to peer-reviewed medical studies, far infrared exposure may offer even more health benefits than we even know about yet!*
