Natural coir mats are made using coarse coconut fibres. The raw material is treated and shaped into firm 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 perform well in covered external spaces. https://entrance-mats17035.suomiblog.com/an-overview-of-coir-entrance-mats-55117227
