An adjustable center post assembly extends vertically from the center of the support base and along a central vertical axis. A seat is secured to a frame connected at a top end of the center post. The seat has a rear buttocks support section and a central narrow frontal projecting section merging therewith through opposed side thigh cavities. An abdominal support pad is secured to an adjustable support arm connected to the saddle frame. The support arm has an upper securing end section adapted for securement of the abdominal support pad and to position same inclined forwardly. The adjustable support arm extends forwardly of the frontal projecting section and aligned therewith and has an adjustable connecting mechanism to position the abdominal support pad for the comfort of a user person above the frontal projecting section.

Abstract: An adjustable and transportable scaffolding (10) is described. It comprises an adjustable leg support mechanism (20) for a scaffolding having vertical corner frame members (11) connected to horizontal frame members (12) and cross-braces (13). The mechanism (20) comprises an open-ended sleeve (21) adapted to receive a support rod (22) therethrough and wherein the support rod has at least a horizontal toothed edge section (23) adapted to secure to a bottom support foot (24). A tooth engaging member (25) is pivotally secured to the sleeve (21) and has a tooth engaging head (26) biased against the toothed edge (23) inside the sleeve (21) for supporting the sleeve about the support rod (22) while permitting upward displacement of the sleeve about the rod. The tooth engaging member (25) can be unbiased from the toothed edge (23) of the support rod (22) to permit downward displacement of the sleeve (21) about the rod (22).
