This mat combines the shoe-cleaning power of coir bristles with the stability of durable natural rubber, in a classic, quick-drying design. Made from sustainable natural materials, the mat is an eco-friendly choice. Classic design features a double border of molded black rubber. Border serves as a heavyweight base and anchors the mat firmly in place. Two drain holes in base let water through, so the mat dries efficiently. Both the rubber and coir surfaces are mildew- and fade-resistant. 100% biodegradable; may be composted after its usable life. For monogramming, specify up to 3 initials. For personalization (maximum 1 line): Medium and Semicircular, up to 8 characters; Large, up to 10 characters; Double Door, up to 11 characters. (Character counts include spaces.) A Williams-Sonoma exclusive.
