Abstract
A seating unit comprising a base configured to be positioned on a floor, a torsional energy unit connected to the base, a back connected to the torsional energy unit and a seat rotatably connected to the torsional energy unit. The torsional energy unit biases the back to a forward position. The torsional energy unit further limits angular rotation of the seat between a substantially horizontal seating position and a substantially vertical seating position.
