The Kaymed memory foam topper pad has a depth of 50mm to provide additional comfort for your whole body, allowing you to be free of aches & wake each day feeling refreshed. Kaymed are at the forefront of sleep technology due to the fact that the memory foam they use is unique to them & manufactured to their own innovative specifications. It is a temperature sensitive foam layer that is specifically designed to soften when it comes into contact with warm surfaces, such as your body heat. It provides relief for your pressure points & encourages healthy blood circulation, as well as reducing the need to toss & turn during the night, meaning a deeper & more restful sleep. The topper pad has a knitted stretch fabric cover that gives it a soft, luxurious feel & is fitted with a zip around the border that allows it to be removed for cleaning. Be aware that a 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's sleep. Working in harmony with your current mattress, the Kaymed memory foam topper pad offers your body an additional comfort layer to help soothe away those aches & pains.
