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.
