A seating structure includes a base, a seat, a backrest connected to the seat, and an electronic circuit supported by the base. The seat or the backrest includes a carrier and a suspension material secured to the carrier and spanning across an opening formed by the carrier. The suspension material includes a plurality of electrostatic discharge fibers. The electronic circuit is coupled to the electrostatic discharge fibers. The electronic circuit includes an electronic processor and a sensor. The sensor is configured to generate an output signal indicative of an electrical parameter of one of the electrostatic discharge fibers. The electronic processor is configured to apply a drive signal to one of the plurality of electrostatic discharge fibers, receive the output signal from the sensor, and determine a state of the seating structure based on the output signal from the sensor.

A seating structure includes a shell having a central portion, opposite outer peripheral edges laterally spaced from opposite sides of the central portion, and at least one biasing array disposed between each of the opposite sides of the central portion and a respective outer peripheral edge. Each of the biasing arrays includes a plurality of spaced apart support members and at least one connector connecting adjacent support members within each array. The biasing array may include a plurality of biasing arrays, with at least one connector connecting adjacent biasing arrays. A second shell may be connected to the outer peripheral edges of the first shell, with an open space defined there between. Each of the opposite outer peripheral edges is independently deflectable in response to a load being applied to the second shell.

The invention relates to a seat for supporting a bottom of a seated user, which seat includes a first seat part for supporting a first part of the bottom of the user and a second seat part for supporting a second part of the bottom of the user. The first seat part is elastically deformable and has a first modulus of elasticity. The second seat part has a second modulus of elasticity which is at least 10 times greater than the first modulus of elasticity.

A seating structure includes a body support member having laterally spaced opposite sides and longitudinally spaced ends. The body support member has a curvature in least one of the lateral and longitudinal directions, wherein the curvature is changeable between at least first and second configurations. The body support member includes a shape memory material extending in at least one of the lateral and longitudinal directions, wherein the shape memory material is attached to the body support member at two spaced apart locations. The shape memory material is contractible between at least a non-energized state and an energized state in response to an application of energy. The shape memory material biases the flexible body support member between the first and second configurations when the shape memory material is contracted to the energized state. Other office systems incorporating shape memory materials are also provided.

A chair component assembly includes a support component adapted to support a portion of a seated user and including a shell member having an outer peripheral edge, the support component further including at least one coupler having an interior and an opening facing the outer peripheral edge of the shell member, and at least one tab member located substantially proximate the opening of the at least one coupler, and an upholstery cover assembly wrapped about at least a portion of the support component and including an edge that is retained within the interior of the at least one cupler by the at least one tab member.
