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://coir-mat-cut-to-size93579.bloguerosa.com/38586380/understanding-coir-door-mats
