Two layers of memory foam and a high-density foam base give this 14-inch mattress a medium to medium-plush feel with plenty of support. A 3-inch top layer of PureFlow™ ventilated gel memory foam conforms to curves and weight to alleviate pressure points. The PureFlow™ ventilated design allows for greater airflow and breathability while SureCool™ gel infusions help maintain a comfortable sleep temperature. Beneath that, a second layer of memory foam infused with StayFresh™ bamboo charcoal provides support and odor and temperature regulation. The thick foam base creates a supportive foundation that provides lasting comfort and relief.
