Coir entrance mats use fibres taken from coconut husks. These fibres are cleaned, dried, and pressed into matting. The fibres create a stiff brushing action. 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://coirmat42947.thezenweb.com/what-are-coir-mats-77896599
