6-inch all-foam mattress with a medium-firm feel, combining comfort, quality and value. A top layer of green tea and gel infused memory foam cushions pressure points while the gel infusion supports a cooler sleep than traditional memory foam, and a convoluted base foam increases airflow. A waterproof cover protects the foam from accidents and stains (do not remove cover). The CertiPUR-US certified foam arrives rolled and compressed in a single box. Covered by a 5-year warranty.
