Coir mats are produced from natural coconut fibre. The husks are processed to form a dense mat surface. The fibres create a stiff brushing action. This structure helps remove dirt and moisture from footwear. They are often used in doorways and porches. They are used inside buildings and under canopies. https://jaidensvsjz.dailyblogzz.com/40305822/understanding-coir-door-mats
