New technology and eco-friendly, the Nature’s Sleep 2.5” 5 lb. Biopolymer Visco Memory Topper. It conforms to your individual shape to relieve pressure points. Imagine sleeping on your side and feeling pressure on your shoulders, hips and knees, then imagine sleeping on a Nature’s Sleep 2.5” 5lb density topper that supports all parts of your body because it conforms to your body weight and temperature so pressure is evenly distributed around your curves. Place this topper on your current mattress to make it a more comfortable nights rest, or on a mattress that is too firm. Can be used on a Sofa bed mattress to stop those bars from cutting into your back, or even placed on the floor when the kids have their friends over. A 300 thread count cotton cover (included) is washable, hypoallergenic and slides over the topper to keep it in place to protect your investment. Made by using 30% Biopolymer, charcoal infused for anti-odor and mildew resistance and negative ion charged for improved sleeper circulation.
