Abstract: A method of assembling a chair component includes providing a first chair member, providing a second chair member moveable between a first position, wherein the second chair member is coplanar with the first chair member, and a second position, wherein the second chair member is parallel with the first chair member, and wrapping a cover member about the first and second chair members. The method further includes providing a drawstring operably coupled with the cover member, drawing the cover member about the first and second chair members when the second chair member is in the first position, fixing an effective length of the drawstring while the second chair member is in the first position, moving the second chair member from the first position to the second position, and securing the second chair member in the second position.

Abstract: A chair back assembly includes a back shell member including laterally extending top, bottom and side portions cooperating to define an open space therebetween, where a portion of the back shell member is located in a lumbar region, a cover having a first surface and a second surface opposite the first surface, wherein the cover covers at least a portion of the open space, and a back frame assembly operably supporting the back shell member and movable between upright and reclined positions, wherein the back frame assembly causes the back shell to flex in a fore-to-aft direction as the back frame assembly is moved between the upright and reclined positions independent of an external force being exerted on the back shell member, and where the lumbar portion of the back shell member remains spaced from the back frame as the back frame is moved between the upright and reclined positions.
