Natural coir mats are made using coarse coconut fibres. 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. Coir mats are commonly placed at entrances. They suit both indoor and sheltered outdoor areas. https://coir-matting05059.thezenweb.com/what-are-coir-mats-77862931
