Uncover the secret to continuous comfort. This sleep luxury mattress is 5-1/2" of durable, high-density polyurethane foam that conforms to your body and doesn't lose its shape. Additionally, when your spouse gets into bed, you won't roll off or bounce around, because the mattress has independent support and contains no springs. The jacquard cover is Teflon treated to repel moisture, creating the perfect sleeping climate. The mattress has a summer side (made of breathable fibers that keep you cool) and a winter side (made of insulating fibers that keep you warm) to ensure year-round comfort. They're also hypo-allergenic as certified by Oeko-Tex 100, a test that recognizes 100 of the most sensitive substances to humans. If a mattress cover has any one of them, it does not pass the test.
