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.

A seat assembly includes a fabric component having a seat surface and a frame including an interior segment directly attached to the fabric component. The interior segment extends from an exterior segment that has a greater flexural resistance than the interior segment.

A blow-molded plastic structure has a hollow interior portion formed during a blow-molding process, and includes first and second outer portions that are spaced apart from each other, with the hollow interior portion disposed there between. The structure includes a pattern of structural stiffening features that are integrally formed in the second outer portion. The pattern of structural stiffening features includes a plurality of tripodal depressions disposed in rows and columns and a plurality of convex regions disposed in rows and columns between the plurality of tripodal depressions. Each convex region has a maximum height between the first and second outer portions. Each of the tripodal depressions extends into the hollow interior portion, includes three indentations disposed adjacent the first outer portion, and includes an island spaced away from the first outer portion. The island has three sides, each of which is disposed adjacent one of the three indentations.

Provided is a chair including a support member that is at least a seat body and a backrest to support an occupant. The support member includes a composite portion at least a part of an outer periphery of the support member. The composite portion includes a first outer periphery that is a part of the first member and a second outer periphery that is a part of the second member. The first outer periphery and the second outer periphery are arranged to overlap each other in a thickness direction of the support member. In the composite portion, at least a part of the first outer periphery is formed into a thin portion thinner in the thickness direction than a part located on an outside of at least the part of the first outer periphery in the first member.

A chair support shell has an integral back portion, seat portion, and joining portion between the back portion and the seat portion. At least a major portion of the support shell comprises a compliant structure, the compliant structure having a plurality of cells interconnected by a plurality of resilient members. The compliant structure provides compliance in the seat portion, compliance in the back portion, and compliance in the joining portion. The compliant structure enables recline of the back portion relative to the seat portion.
