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. They are often used in doorways and porches. They perform well in covered external spaces. https://coir-entrance-matting74702.bloggerchest.com/39909050/an-overview-of-coir-entrance-mats
