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 gelCore cool touch memory foam, our proprietary M48 high density memory foam, and a special layer of UltraCore rebound memory foam. The result an incredibly soft yet remarkably supportive bed. Every foam mattress by MLILY is built with CertiPur-US tested and certified foams, and fabrics that meet or exceed the Oeko Tex Standard 100 for Confidence in Textiles. MLILY is proud to utilize components which lessen our environmental impact without sacrificing the quality and luxury our customers deserve.
