Natural coir mats are made using coarse coconut fibres. These fibres are cleaned, dried, and pressed into matting. The fibres create a stiff brushing action. The design supports effective dirt control at the door. They are often used in doorways and porches. They are used inside buildings and under canopies. https://coir-mats29493.spintheblog.com/40102029/understanding-coir-door-mats
