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. 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://rowandkidu.luwebs.com/39936160/an-overview-of-coir-entrance-mats
