Abstract: A furniture connector for connecting a first member having a longitudinal axis to a second member positioned transverse to the first member is disclosed. The second member has an interior passage in at least one end thereof and a hole communicating with the interior passage. The furniture connector includes a block, a flange, at least one first bore in the block, at least one first fastener, and at least one second bore in the block transverse to the first bore, and at least one second fastener. The block is removably received within the interior passage of the second member. The flange is secured to the block and abuts against the first member. The first bore extends through the block and the flange. The first fastener passes through the first bore and engages the first member. The first fastener removably secures the block to the first member. The second fastener passes through the hole in the second member and is received in the second bore.

Abstract: An office chair incorporates a lumbar support in the lumbar region of the back of the chair. The support includes an arcuate lumbar support element and a carrier for the element, which is pivotally coupled to the back for movement between positions in which the support element provides respectively maximum and minimum support for the lumbar region of the person using the chair. The carrier can be locked in an adjusted position. The support element is resiliently flexible so that its curvature varies between a maximum in the maximum support position and a minimum in a minimum support position of the lumbar support.

Abstract: An office chair has a back with a central portion and respective wings or bolsters on opposite sides of the central portion. The wings are coupled to the main central portion by arm structures that are designed to allow the wings to flex rearwardly from a rest position and back to the rest position in response to forces exerted by a person seated in the chair, but to resist forces tending to move the wings forwardly from the rest position.
