This 3" thick memory foam mattress topper will bring new life to any mattress. Open cell construction yields a longer lasting, more resilient foam that will not leave long-lasting body impressions. The soft, doughy consistency quickly conforms to weight and pressure. This mattress topper will help relieve neck, back and shoulder pain by reducing pressure points. This in turn helps to correctly align your spine by supporting the natural curves of your head, neck and shoulders. Our unique memory foam formula is naturally resistant to allergens and dust mites. The 3-Year warranty provides increased peace of mind for your purchase.
