At 5cm deep this mattress topper offers a medium layer of additional comfort & luxury for your mattress. The 5cm 60kg Small Double Memory Foam Mattress Topper is available with a choice of covers including Essentials poly-knit, Cool Max®, Outlast®, or as foam only (no cover). Outlast® Cover: The unique fabric draws heat away when your temperature rises, the heat energy is stored, & then released when you begin to cool down, keeping your body not too hot, not too cold, but just right during the night. This regulation of body temperature means you're less likely to wake during the night, which ensures the deepest sleep possible. Cool Max® Cover: The Cool Max® fabric is made from unique fibres which allow air to permeate & reduce heat & moisture build up, meaning your body stays cool & dry throughout the night. A memory foam topper provides comfort for your whole body during the night, meaning you can wake up feeling refreshed & free of any minor aches & pains. Memory foam also provides relief for your pressure points, which encourages healthy blood circulation, as well as reducing the need to toss & turn during the night, meaning a deeper & more restful sleep. Manufactured in the UK with quality raw materials & detailed finishing, you can purchase your mattress topper with the confidence of a 12 month manufacturer&39s warranty from one of the UK&39s leading memory foam mattress & 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 & pressure relief to a firm or tired mattress. If your mattress is in bad condition & has any lumps or dips, then we recommend that you consider a new mattress for a better night&39s sleep.
