Natural coir mats are made using coarse coconut fibres. The raw material is treated and shaped into firm matting. The finished mat has a rough texture. 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://alexisrutqm.ageeksblog.com/38084018/an-overview-of-coir-entrance-mats
