Carpet base is a type of wall base made of carpet. In some hospitality applications and some contract flooring projects, we cut and bind carpet base using the same material as we install on the floor to create a perfect match. We bind the top edge for cosmetic and structional benefits. Carpet base can be fabricated to any width so that, once attached to the wall, the base is as tall as desired. The average customer will prefer 4-inch base. As with vinyl base and rubber base, carpet base easily contours to curved walls.
