A folding shelf may include a first shelving unit having first side frames, one or more shelving boards, a first retractable control unit; and a second shelving unit having second side frames, one or more second shelving boards, a second retractable control unit. The first/second retractable control unit may include a first/second main body; a first/second pole partially received in the first main body; and a first/second locking member. When the folding shelf is folded, the user can first twist a first/second locking element to untightened first/second main body and first/second pole. The user can then lift the side frames in the center portion as to collapse the shelf. More specifically, the sliding movement of the first pole and the second pole can bring two side frames toward the center portion of the folding shelf to significantly minimize the size thereof.
