Coir entrance mats use fibres taken from coconut husks. 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://throw-down-entrance-mats50368.arwebo.com/62028522/understanding-coir-door-mats
