Offering a medium and comfortable support, the Essentials mattress combines Silentnight body-contouring pocket springs and body moulding memory foam. The high-tech memory foam layer is temperature sensitive and designed to soften when in contact with warm surfaces, moulding itself to your contours. It features layers of Eco-Comfort fibres that are designed to keep you cool and helps to regulate your body temperature during the course of the night. The fibres have been treated with Purotex - a natural treatment that combats allergens to create a safe, hypoallergenic and dust mite-free sleeping environment. The interior of the mattress is made up of small diameter pocket springs with each one individually wrapped in its own cloth sleeve for total flexibility. Not directly attached to any surrounding springs, they are designed to push back against the sleeper39;s body weight to provide piston-like support. Not too hard and not too soft, it39;s medium support is an ideal choice for people of average build and weight.
