Natural coir mats are made using coarse coconut fibres. The husks are processed to form a dense mat surface. The fibres create a stiff brushing action. 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://entrance-hall-matting-sup93791.onesmablog.com/an-overview-of-coir-entrance-mats-80611354
