Best Gel Memory Foam: Our memory foam mattress provides a good sleeping surface. This medium hardness mattress will respond to your body's temperature and begin to shape you as you lie down. Then, the weight is evenly distributed along the surface, relieving stress points and helping you sleep more without tossing and turning. Green tea brewing can have a calming effect, allowing you to spend a completely relaxed night. Our mattresses are made of CertiPUR US certified foam and are wrapped in a soft fabric covering.
