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. 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://hectorhjhhf.pointblog.net/what-are-coir-mats-88318264
