After completing extensive research 'The Sleeping Zone' Co. Ltd has developed a new range of memory foam mattresses that will fit perfectly into your lifestyle. The three revolutionary zoned sleep systems take advantage of the latest developments in foam technology to take sleep, comfort and support to the highest level. Each system offers different benefits but all are designed and manufactured to the highest specifications, using materials to deliver a superior product. Selected models in the ultra Zone collection contain natural latex and additional level of comfort ensuring a healthy nights sleep. The sleeping zone mattress collection makes full use of the 'comfort' properties of latex, visco-elastic and reflex foam. This advanced material distributes weight evenly to avoid pressure build-up in any sensitive areas of the body. This dispersion of pressure can be measure, so we have developed a system that offers the highest levels of support and comfort, whilst ensuring there is the minimum heat build up.
