Firm Feel to Relieve Sleeping Pains
This mattress has a firm feel. The thicker comfort layer makes this mattress feel softer than the 6" or 8" mattresses.

Open Cell Memory Foam
We pride ourselves on staying at the front of sleep technology, which is why we make all of our foam using open cell construction. The unique manufacturing process makes a softer, doughier foam that will quickly conform to your body weight and position. The open-cell construction also optimizes air flow to keep you cool and comfortable while you sleep.

Safe for You and the Environment
Our foam is CertiPUR-US® certified, which means this product has been independently tested for content of materials used, physical performance, and environmental stewardship. Careful construction guarantees no prohibited phthalates, no ozone depleters, no CFCs, no mercury, lead or heavy metals, no formaldehyde, no PBDEs, and low emission (VOCs) for indoor air quality.

25 Year Warranty
Rest easy with this 25-year warranty that protects the mattress and cover against manufacturer's defects.
