Coir entrance mats use fibres taken from coconut husks. The raw material is treated and shaped into firm matting. The fibres create a stiff brushing action. The design supports effective dirt control at the door. Coir mats are commonly placed at entrances. They are used inside buildings and under canopies. https://throw-down-entrance-mats36776.onesmablog.com/an-overview-of-coir-entrance-mats-80381069
