This Memory Foam Sprung cool touch grey tufted mattress has 8 individual comfort layers providing the sleeper with extra comfort and support, carefully hand-tufted tufts keep the layers tightly held together so the sleeper can enjoy an endless night's sleep. With an 8 inches deep base of approximately 23cm, the mattress has a 13.5gauge open coil spring unit, the steel wire provides a firmer and much more supportive feel with less spring feel which distributes the sleeper pressure and weight evenly across the mattress surface for extra comfort and support. The mattress has been carefully designed with a super-soft cooling top cover which is gentle on the sleeper's skin for a cool sleeping sensation. It has a quilted breathable border which allows airflow to pass through the tiny air holes ventilating the mattress keeping it odor-free and maintaining the sleeper at room temperature. Designed single-sided, simply rotate every so often to keep it in pristine condition, with hypoallergenic and anti-dust mite features. Delivered vacuum packed, rolled, and boxed for the convenience. - eXtreme Comfort Ltd Cool Touch Hand-Tufted with Memory Foam & Spring with White Border Mattress - Size: King
