Coir entrance mats use fibres taken from coconut husks. The raw material is treated and shaped into firm matting. The fibres create a stiff brushing action. This structure helps remove dirt and moisture from footwear. Coir mats are commonly placed at entrances. They suit both indoor and sheltered outdoor areas. https://codyamsym.aioblogs.com/92403499/understanding-coir-door-mats
