Representing the next generation in mattress toppers, Sleep Better visco-elastic memory foam reduces nighttime tossing and turning to provide a better night sleep. The innovative, hypo-allergenic material takes its cues from the bodys shape--adjusting and contouring to any form. The resulting customized fit distributes weight more evenly and relieves pressure points. It allows for better blood flow so the body makes fewer adjustments in search of a more comfortable position. And to top it off, the temperature-smart, open-cell foam breathes freely to facilitate air circulation and keep things cool. The pad measures 58 by 77 by 3 inches and covers the entire surface of a queen mattress. It carries a density of 2-1/2 pounds per cubic foot. Thanks to its therapeutic features, it benefits the bed-confined and is frequently used in hospitals. It is also great for pregnant women, the elderly, and anyone who needs a good night rest. Spot cleaning with warm water and a little soap removes most stains. This product is made in the USA and comes backed by a 5-year warranty.
