Abstract: 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.

Abstract: A tablet assembly for use in a space partially defined by a wall structure having a substantially planar wall surface, the assembly comprising a first coupler supported by the wall structure, a tablet support arm assembly having a support arm length dimension between proximal and distal ends, the proximal end mounted to the first coupler adjacent the planar wall surface for rotation about a first vertical axis through a first range of motion between first and second first-axis limit positions, the arm assembly extending from the planar wall surface to form acute angles with the planar wall surface in each of the first and second first-axis limit positions and a tablet member forming top and bottom surfaces and having a side edge, the tablet member supported at the distal end of the arm for rotation about a second vertical axis through a second range of motion between first and second second-axis limit positions, wherein the limit positions limit the tablet member to positions in which the side edge of the tablet member is constrained from contacting the planar wall surface.
