This plush, 16 inch thick mattress comes with four layers that work together to bring you optimal comfort in your sleep. The first layer is a 1 inch bamboo charcoal memory foam layer sewn into the soft outer cover. Bamboo charcoal is especially good for sensitive skin and has better thermal regulation. This layer can be removed by taking off the mattress cover. Directly beneath that is a 3 inch layer featuring our softer and lighter memory foam, ventilated for breathability and comfort. Beneath that is a 2 inch comfort layer of natural latex. Resilient latex pairs well with memory foam because its instantaneous give will better support to your body. The combination of latex and memory foam provides optimal orthopedic support and pressure relief to help alleviate neck, back and shoulder pain. We used open-cell memory foam construction to create a longer lasting, more resilient foam that will not leave long-lasting body impressions. Made of a cozy TENCEL blend fabric (10 percent TENCEL lyocell, 90 percent polyester), the soft cover creates a breathable air layer at the top of the mattress. LUCID memory foam and latex is naturally resistant to allergens and dust mites. The foam in this product is CertiPUR-US certified which means it has been independently tested for safety of materials used, physical performance, and environmental stewardship. Careful construction guarantees no prohibited phthalates, no ozone depleters, no CFCs, no mercury, no formaldehyde, no PBDEs, and low emission (VOCs) for indoor air quality. This mattress will come vacuum packed. After your mattress arrives, simply take the package into the right room, remove it from the box and protective wrap, and then watch as it expands to its original shape.
