Abstract: A seating unit for use in a space including a floor surface, the seating unit comprising a base including a bottom ring adapted to be supported above the floor surface, a pan attached to the bottom ring and adapted to support articles above the floor surface, a central hub positioned above the pan and legs extending from the central hub to the bottom ring and a seat structure comprising a one-piece seat shell rotatably attached to and positioned above the central hub.

Abstract: A seating unit having a seat structure, a base, and optionally a tablet assembly is provided. The seat can turn freely through 360 degrees of rotation. One base includes three or more legs and offset casters. Alternatively, the base includes a pedestal having a tapered gas cylinder. The tablet assembly includes a support arm, a pivot assembly attached to one end of the support arm tablet, and a tablet attached to the pivot assembly. The tablet can rotate horizontally on the support arm. The tablet assembly also includes a mounting assembly attached to the other end of the support arm. The support arm can rotate relative to the seat structure. Rotation of the tablet relative to the support arm and rotation of the support arm relative to the seat structure is constrained by stops in the pivot assembly and tablet mounting assembly, respectively.
