Supreme comfort meets advanced support with the Gelcare Discovery. A two inch layer of cool Gelcare memory foam works with a one inch layer of ventilated memory foam to gently conform and contour your body. Gel memory foam provides a more comfortable and cooler sleeping surface. Gelcare memory foam is the next step in memory foam technology. All Gelcare mattresses are made of high quality memory foam and gel material. They are constructed with heavier and denser materials.
