What Is a Chair Rail?

http://www.chairrailzone.com/ A chair rail is a molding, that runs horizontally along the periphery of a room, at a height of 30 to 32 inches from the ground level. This molding protects the wall surfaces from getting damaged by top ends of chair backrests, when they are placed near walls.
