The Sleep Science™ Black Diamond bamboo charcoal visco memory foam is based on a specialized product developed after researching the 1,000-year-old practice of utilizing bamboo charcoal fibres for its unique properties. The Comfort Artisans at Sleep Science blended bamboo charcoal fibres into its proprietary visco memory foam to neutralize moisture in localized areas and dissipate odours. This mattress is perfect for back and stomach sleepers seeking a firm, hybrid mattress with the comforts of specialty memory foam, the lofty support of latex and a temperature-neutral environment.
