Coir mats are produced from natural coconut fibre. The raw material is treated and shaped into firm matting. The fibres create a stiff brushing action. The fibre texture scrapes mud and debris from shoes. They are often used in doorways and porches. They suit both indoor and sheltered outdoor areas. https://elliotajobh.answerblogs.com/40218177/an-overview-of-coir-entrance-mats
