The Double Egg Box Memory Foam Mattress Topper features 60kg/m⊃3 high density memory foam. This high density memory foam ensures longevity for your mattress topper, and also offers a high level of pressure relief. A memory foam topper provides comfort for your whole body during the night, meaning you can wake up feeling refreshed and free of any minor aches and pains. Memory foam also provides 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. 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.
