Abstract: A chair, which has a cylinder for controlling the configuration of a chair or the seat height of a chair, is operated by a flexible cable. The flexible cable is attached to an adjustment member that is not fixedly attached to the cylinder, thereby permitting the cylinder to be replaced without replacing the adjustment member.

Abstract: A seating apparatus has a support element having an upright extending from a floor and a swing arm pivotably mounted to the upright about a generally vertical pivot axis. A work surface is secured to the upright above the swing arm, and a seat is mounted on the swing arm, the seat having a seat base upon which an occupant can be seated. The swing arm is pivotable between a stowed position wherein the seat base is tucked substantially underneath the work surface, and a deployed position wherein the seat base is substantially clear of the work surface. The seating apparatus is also provided with a flat coiled torsion spring for biasing the arm to the stowed position, the torsion spring having a first end fixed directly or indirectly to the upright and a second end fixed directly or indirectly to the swing arm.
