Natural coir mats are made using coarse coconut fibres. The raw material is treated and shaped into firm matting. The fibres create a stiff brushing action. The fibre texture scrapes mud and debris from shoes. Coir mats are commonly placed at entrances. They are used inside buildings and under canopies. https://caidennfnys.rimmablog.com/38289009/what-are-coir-mats
