Coir entrance mats use fibres taken from coconut husks. The husks are processed to form a dense mat surface. The finished mat has a rough texture. The fibre texture scrapes mud and debris from shoes. They are often used in doorways and porches. They perform well in covered external spaces. https://coir-entrance-matting53948.ampblogs.com/an-overview-of-coir-entrance-mats-76228707
