Best Price Mattress 14-inch memory foam mattress provides a great sleeping surface. In normal temperatures it is somewhat firm, but when you lay down, it starts reacting to the temperature of your body and begins to mold itself to your shape. Then, weight is evenly distributed along the surface, relieving pressure points and helping you to sleep more without tossing and turning. The breathable ventilated foam design optimizes airflow, reducing body heat and helping to keep your mattress fresh for a longer time. Our mattress is made with CertiPUR-US certified foams and wrapped in a soft fabric cover.
