The Harmony Coolmax Memory Foam Mattress has been designed as with all our memory foam mattresses to maximize your contact with the mattress therefore reducing the pressure points on your body. The creation of less pressure points promotes better blood circulation whilst the temperature sensitive properties mould to the exact contours of your body. This provides optimum support for your neck, back, shoulders and legs and will therefore reduce the number of times you will turn in the night Covering the mattress is the Cool removable luxury Quilted coolmax cover, manufactured to be hypo allergenic, anti microbial and fungo-static. The combined attributes can significantly help to reduce dust mites.The Coolmax cover works by removing moisture away from the body by increasing the surface area. It allows greater evaporation of moisture, leading to a cooling effect of the fabric. This is an innovative fabric which 'breathes' therefore when you lie on it, the heat and moisture generated by your body will evaporate within the first hour of rest, and the fabric will keep your body cool throughout the night. This is made possible by a special new fibre developed by Du Pont, which allows air to flow freely through the fabric and through the core, ensuring that no moisture will be trapped inside the mattress. 5 YEARS MANUFACTURERS GUARANTEE.
