Natural coir mats are made using coarse coconut fibres. 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 perform well in covered external spaces. https://coir-entrance-matting28135.worldblogged.com/45963699/what-are-coir-mats
