Add character to your front door with these classic design door mats. These rubber and coir molded doormats are made with a heavy rubber backing that anchors it in place. Coir mats are one of the most durable entrance floor mats due to their bristly surface and molded rubber backing. Coir is the most popular natural fiber used in doormats and is mold and mildew resistant. Its dense rugged fibers scrape off dirt, mud, snow and debris from shoes; its extra durable rubber backing provides an anti-skid surface and long lasting in the harshest of weathers.
