8-inch all-foam mattress with a medium 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 stretch knit cover is soft and comfortable. The CertiPUR-US certified foam arrives rolled and compressed in a single box. Covered by a 5-year warranty.
