Sleep Science Black Diamond 11" King Memory Foam Mattress with Foundation
The Sleep Science Black Diamond Memory Foam Mattress layers proprietary bamboo charcoal visco memory foam and supportive latex. The Sleep Science black diamond visco memory foam is the latest advancement in the Sleep Science Memory Foam line.
Black diamond visco memory foam was developed after researching the 1000 year old practice of utilizing bamboo charcoal fibers for its unique properties. Sleep Science blends bamboo charcoal fibers into its proprietary visco memory foam to create the black diamond visco memory foam. Bamboo charcoal fibers neutralize moisture in localized areas; eliminates odors and increases the antibacterial properties of the foam.
The top layer of this mattress consists of 5 lb density, black diamond visco memory foam. It is the perfect top layer to absorb moisture and dissipate odor. The second layer is made of Sleep Science 5 lb density premium visco memory foam to provide an added layer of comfort. The latex layer provides exceptional support for the visco memory foam. The mattress features the Sleep Science patented Wedge, edge to edge support system. The Wedge is an angled piece of firm polyurethane foam that runs along the outside edge of the mattress. It provides a stable sitting edge, 20% more sleeping surface than the competition and extends the life of the mattress by preventing the foam from spreading after prolonged use. The base features the Sleep Science air channel base which is made of high resilient polyurethane foam, that is scored horizontally and vertically in 1" grooves to promote air circulation in the center of the mattress, creating a temperature neutral environment.
