The Coir Mat is made from coconut fibers which are extracted from dry coconut shells. Since coconut fiber is an 100% natural material that is soft and durable, the coir mats made from coconut fiber can stand the test of time. They are made from the long, brown fibers of the coconut husk. Thus, they are far safer for the environment than doormats made from synthetics that are non-biodegradable and might even trigger allergic reactions in those with sensitivities to these materials. The fibers are removed from the husk and processed into yarn, or coir. The offered Coir Mat is very effective.
