Coconut Coir: This light brown door mat is made of 100% pure coconut coir, which is one of the strongest natural fibers in the world. The material easily captures moisture, dirt, and other particles. Due to the way our coir mats are cut, sizing may show slight variations. In addition, light shedding may naturally occur. Indoor and Outdoor: The rug is designed specifically for both indoor and outdoor use, making it ideal for any room or entryway in your home. It's low-maintenance and built to last.
