At 2.5cm deep, the Coolmax Comfort Memory Foam Mattress Topper simply slots neatly between your mattress and your bottom sheet to provide an additional layer of comfort to your current mattress. Memory foam also offers relief for your pressure points, which encourages healthy blood circulation, as well as reducing the need to toss and turn during the night, meaning a deeper and more restful sleep. The Coolmax® cover is made up from fibres which allow air to permeate and reduce heat and moisture build up, meaning your body stays cool and dry throughout the night. Please note that unlike our other mattress toppers the cover on our Coolmax Comfort Memory Foam Mattress Topper cannot be removed. Manufactured in the UK with quality raw materials and detailed finishing, you can purchase your mattress topper with the confidence of a 12 month manufacturer's warranty from one of the UK's leading memory foam mattress and topper manufacturers. Please be aware that a memory foam mattress topper cannot solve the problem of a dipped or damaged mattress, but offers additional comfort and pressure relief to a firm or tired mattress. If your mattress is in bad condition and has any lumps or dips, then we recommend that you consider a new mattress for a better night's sleep.
