The 15" Bliss is designed with a single goal in mind: offer a level of glorious pressure relief unparallelled in the market, while providing premium support. Made with a silk cover and seven inches of our best memory foams, no element of luxury was overlooked. Below the silk blended cover is a quilted layer of heat-dissipating bamboo memory foam, for a cooler more comfortable sleeping surface. Combine this with gel Core cool touch memory foam, our proprietary M48 high density memory foam, and a special layer of Ultra Core rebound memory foam. The result an incredibly soft yet remarkably supportive bed.
