Coir entrance mats use fibres taken from coconut husks. These fibres are cleaned, dried, and pressed into matting. The fibres create a stiff brushing action. The fibre texture scrapes mud and debris from shoes. They are often used in doorways and porches. They suit both indoor and sheltered outdoor areas. https://entrancemats49357.blogadvize.com/47725506/understanding-coir-door-mats
