Natural coir mats are made using coarse coconut fibres. The husks are processed to form a dense mat surface. The fibres create a stiff brushing action. This structure helps remove dirt and moisture from footwear. Coir mats are commonly placed at entrances. They are used inside buildings and under canopies. https://coir-matting05059.thezenweb.com/what-are-coir-mats-77862931
