The flat surface of a table, exclusive of the cushions. The bed is covered with billiard cloth like the cushions. The playing area of the table consists of the bed except where the cushion overhangs the bed , i.e. it is all of the bed between the cushion noses. Quality beds are made of smooth-ground slate , though very cheap tables may use particle board or plywood. The earliest beds were simply the surfaces of the wooden tables on which the game was played.
