This is pure luxury at a price that makes sense. The 10" thick mattress features 2.5" of 3.0 lb plush memory foam and a 7.5" polyurethane supportive foam base. The open cell technology allows air flow, keeping you cool and comfortable while you sleep. 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 will help reliive 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. The memory foam is naturally antimicrobial and resistant to allergens, mold, bacteria and dust mites. The soft velour zip-off cover is antimicrobial and anti-dust mite and can easily be removed and laundered. The 20-Year warranty provides increased peace of mind for your purchase.
