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://entrancemats69875.spintheblog.com/40088004/understanding-coir-door-mats
