ABSTRACT:
A foldable bookcase includes a frame with two sidewalls pivotably connected to two vertical sides of the frame and a top board and a bottom board are pivotably connected to the top side and the bottom side of the frame. The top board, the bottom board and the two sidewalls are pivotable relative to the frame. The top board includes bosses which are engaged with holes in the sidewalls. A rear board are fixed to the top board by a bolt and stops extend from an inside of the rear board so as to be in contact with L-shaped bent edge defined in the rear side of each of the sidewalls. By this arrangement, the bookcase is easily assembled and the pivotable top board, bottom board and two sidewalls allow the bookcase to be folded into a compact size.
