Beverly Hills Bed memory foam mattress overlay toppers were designed to the exact specs of the Tempur-pedic toppers at half the cost of the nationally recognized name. They work great if your mattress is firm and you would like a softer feel. They hug the natural curve of your body to create the correct sleeping posture which will improve circulation, significantly reduce snoring, high blood pressure, and morning headaches. Using your body heat mass, it conforms to the exact shape and weight of your body. These overlay toppers will not form body impressions as lower density toppers do because they are made with 3 inches of Nasa Visco elastic 5.3 density memory foam, covered in a zippered washable Jacquard Velour Cover.
