A collapsible support frame includes a collapsible frame that extends upwardly from a ground surface and has a fixed vertical height. Such a frame includes a plurality of rectilinear rails equidistantly spaced apart and disposed at opposed corners of the frame. The frame further includes a seat support section, a plurality of rods, and a seat belt directly connected to the seat support section and projecting forwardly towards an anterior side of the frame. A mechanism for maintaining the selected rods is evenly registered along a horizontal plane when the frame is erected such that the selected rods become downwardly displaced from the horizontal plane when the maintaining mechanism is repositioned along a longitudinal length of the selected rods as the frame is collapsed.
