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. The fibre texture scrapes mud and debris from shoes. Coir mats are commonly placed at entrances. They suit both indoor and sheltered outdoor areas. https://rowanjijmj.blogmazing.com/38358062/an-overview-of-coir-entrance-mats
