A coir mat is a type of doormat made from the husks of coconuts. The fibres are woven together to create a durable, long-lasting, water-absorbent mat that's great at getting dirt and moisture off your shoes.
The number 1 problem with coir door mats is the mess their fibres make when they shed. Being an entirely natural product, coir does lose some fibres over time. These are annoying to clear up and require vacuuming about once a week.
