The ThermaBalance Tencel Mattress Pad ensures an ideal sleeping experience in any environment. The TENCEL® filling is an extremely absorbent natural fiber that wicks and disperses moisture better than any other natural fiber and promotes a healthy, cool and dry sleep foundation. The 100% fine cotton fabric cover is smooth and absorbent. The fitted skirt will accommodate up to an 18” mattress depth. This mattress pad suits all environments but is especially effective in warmer climates.
