Inspired by Martha Stewart's approach to functional, organized living, SleepComplete by Martha Stewart marries a new assortment of premium mattresses with a simple system to determine your best sleep solution. A removable cover comprised of breathable knit jacquard with moisture-wicking fabric and cooling technology is your first contact with the medium-firm king-size mattress. Cooling gel memory foam, comfort foam, and highly resilient support foam layers are CertiPUR-US Certified and provide motion isolation ideal for co-sleepers. Individually wrapped pocket springs, with 5-way zoning, ensure pressure relief and motion transfer reduction. Extra firm perimeter coils provide edge support for seated positions and help prevent sagging. This mattress is softer than our firm option, but firmer than our medium option. The dual-action cooling mattress is suitable for all sleep positions. Optimize your sleep experience and pair this mattress with one of our premium Martha Stewart beds for an exceptional look and luxurious comfort. Color: White.
