The Sareer Diamond Memory Foam small single mattress is the perfect size for a child's bed, and has a multitude of healthy, orthopaedic features to allow your little one to rest at ease. Internally, the mattress is spring-free, being comprised of six inches of reflex foam and two inches of memory foam. These foams work together to provide a medium-tension, flexible surface which adjusts quickly and easily under your child's weight to mould and meet their individual sleeping posture. Added benefits of this mattress include a removable cover, anti-dust-mite treatment, and a stretch cover.
