Coir entrance mats use fibres taken from coconut husks. 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 perform well in covered external spaces. https://coir-mat42841.ltfblog.com/38038269/what-are-coir-mats
