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 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://beauivgmq.eedblog.com/39450488/what-are-coir-mats
