Disclosed are a collapsible supporting frame and furniture having a collapsible supporting frame. A frame includes first and second supporting units, and first and second bar units disposed between the first and second supporting units. Each of the first and second supporting units includes a first leg, a second leg, and one or more lateral connecting bars disposed between and fixedly connected with the first and second legs. Each of the first and second bar units includes first and second bars rotatably connected with each other at their proximal ends. A distal end of the first bar is rotatably connected with the first or second leg of the first supporting unit. A distal end of the second bar is rotatably connected with the first or second leg of the second supporting unit.

Proposed is a folding seat that is capable of being folding to various positions by controlling a lever and the folding seat is capable of improving utilization of space around the folding seat. According to an embodiment of the present disclosure, the folding seat includes: a seat frame; a seat back frame cross-arranged in back of the seat frame, the seat back frame having a first side rotatably coupled to the seat frame; and a locking portion coupled at a first side thereof to the seat back frame and rotatably coupled at a second side thereof to the seat frame at a position between the seat frame and the seat back frame, wherein the locking portion is configured to be inserted into a rear portion of the seat frame or to be separated from the seat frame according to an operation thereof.

A folding mechanism includes a pivot seat unit and at least three support units disposed about an axial line and pivotally connected to the pivot seat unit. Each of the support units includes a support rod.

Rotation of any one of the support rods of the support units relative to the pivot seat unit drives an adjacent one of the support rods to rotate, such that when any one of the support rods is rotated relative to the pivot seat unit, the other support rods are in turn driven to rotate relative to the pivot seat unit so as to convert the support units between a folded state and an unfolded state.
