Highlights The mattress padding is made from cold gel memory foam, which utilizes a special process to regulate temperature and keep the body optimally cool all night long. The medium firmness of the foam provides adaptive comfort and support, as well as allowing perspiration to evaporate easily and keep you dry.Using cooling fibers made from soft, breathable rayon, you can wake up each night feeling refreshed by a cool mattress. Memory foam mattresses help evenly distribute weight and protect the spine, providing customized comfort and pressure relief by adapting to different body shapes.The base fabric is made of a non-slip fabric that increases friction and stays in place, plus there are extra straps on the corners of the mattress to keep it snug. With the non-slip design, you won't have to adjust the mattress as often the next day when you lie in bed. The cover and zipper are machine washable, which means you can keep your mattress clean, extending its life to some extent and avoiding the hassle of throwing it away too often.The memory foam mattress is CertiPUR and the rayon of the cool mattress cover is OEKO-TEX . Temperature setting is 40℃/100℉, tumble dry low, do not iron, do not dry clean.
