Natural coir mats are made using coarse coconut fibres. These fibres are cleaned, dried, and pressed into matting. The finished mat has a rough texture. This structure helps remove dirt and moisture from footwear. They are often used in doorways and porches. They are used inside buildings and under canopies. https://anti-slip-matting95261.wizzardsblog.com/39771168/an-overview-of-coir-entrance-mats
