This invention relates to a height adjustable pedal-ring mechanism for bar stool. This mechanism comprises a main shaft, a taper sleeve, a cross-shaped support frame with a central tube, a pedal ring, and a base frame. The pedal ring is connected to the cross-shaped support frame. The taper sleeve has an outer spiral line on the upper part of the taper sleeve and an outer gradient slope on the lower part of the taper sleeve. The cross-shaped support frame is equipped with a central tube at the central part of the cross-shaped support frame. The central tube has an inner spiral line matching with the outer spiral line of the taper sleeve and an inner gradient slope matching with the outer gradient slope of the taper sleeve. This mechanism employs the outer gradient slope of the taper sleeve and the inner gradient slope of the central tube to fix the vertical position of the pedal ring.

An ergonomic pedestal seat that interacts with the sitter's musculoskeletal system in a way that optimizes their use of gravitational forces is provided. This seat orients a sitter toward an alignment that encourages a balance between gravity's descending force and its ascending counterforce, the ground reaction force. The seat comprises a four-tier seat base, a non-vertical central supporting column and a contoured seat pan. The base has a surface that allows the sitter to sustain a stable alignment and to rock forward or sideward or both, as well as a Lazy Susan mechanism that permits turning. This seat supports the sitter through a range of seated activities, including quiet activities such as meditation and complex tasks requiring reaching, bending and turning. When on this seat sitting becomes a source of pleasure rather than an activity of drudgery.

A high-seat folding chair includes two pairs of front legs and rear legs pivotally connected with each other so as to be operable to unfold or fold the folding chair. When unfolded, each of the front legs and the rear legs form an angle relative to a horizontal plane. A footrest is mounted between the two front legs. Two opposite portions of the footrest bend symmetrically in a horizontal direction to form horizontal portions, respectively. The two horizontal portions further bend upward to form inclined extensions, and a portion of each inclined extensions forms a flat portion. An angle defined between the inclined extension and the horizontal portion is equal to an angle defined between the front leg and the horizontal plane. The inclined extensions of the footrest are respectively affixed with the two front legs, such that the footrest is mounted in horizontal.
