Natural coir mats are made using coarse coconut fibres. The husks are processed to form a dense mat surface. The finished mat has a rough texture. 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://entrance-mats82468.ampblogs.com/an-overview-of-coir-entrance-mats-76525008
