This 3-inch mattress topper features 1 inches of Elate Memory Foam. Unlike traditional memory foam, this product is infused with graphite, copper, and silver to prevent the growth of microbes. It also pulls heat away from the body, ensuring a comfortable sleep temperature throughout the night. The Elate Memory Foam layer sits atop 1 inches of high-density CertiPUR foam and comes with a removable, dry-cleanable cooling cover. This upgraded version of the 3-inch Slumbercrest Elate Cooling Topper boasts more Elate Memory Foam and superior cooling. Made in the USA, this product also comes with a 3-year full warranty.
