Abstract

Stackable or nestable single person seating assemblies that include a leg support defined by a plurality of legs and a crossbar that extends between the plurality of legs. The seat assembly includes a back that is rotatably coupled to the plurality of legs and a seat that is rotatably coupled to the back. A biasing element extends from the leg support to the seat and is coupled to a respective leg. Respective portions of the biasing element provide a third pivot axis and a fourth pivot axis that are activated when the back is reclined relative to the seat.
