Coir entrance mats use fibres taken from coconut husks. 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 suit both indoor and sheltered outdoor areas. https://johnnyuxxil.bloggerchest.com/39298402/an-overview-of-coir-entrance-mats
