Tommy Bahama luxury combined with three separate levels of protection sounds like a dream. Stain resistant fabric offers protection against usage. Silver infused antimicrobial treated polyester blocks odor issues. Whisper quiet waterproof lamination on the bottom of the pad protects your mattress. This machine washable mattress pad has deep pockets designed to fit mattresses up to 18 inches in height. With 12 ounces per square yard it is considered a thick mattress pad (versus a typical 6-8 oz. sq./yd. model).
