MATERIALS: Made out of 100% Polyester with TPR backing. Non slip backing ensures your bath mats stay in place! SIZE: First Bath mat measures 21" x 34" inches. Second Bath mat measures 17 x 24" inches. Our microfiber bath rug is much more absorbent than cotton bath rugs. High-pile helps save your floors from dripping water while you're stepping out of the bath, shower, spa, or getting ready by the sink. Moisture is trapped in the mat's deep pile, allowing the rug to dry quickly and cleanly. Machine wash in cold water with mild detergent. Tumble dry on low heat or lay to air dry, the color will not fade with continual uses.
