Coir entrance mats use fibres taken from coconut husks. 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. Coir mats are commonly placed at entrances. They suit both indoor and sheltered outdoor areas. https://coir-entrance-mat37023.blogdal.com/39833048/what-are-coir-mats
