A lounge assembly comprising a lower wall structure including at least first and second spaced apart side walls and a rear wall that together form an assembly space, each of the side walls and rear wall including an internal surface, a seat assembly supported between the first and second side walls, a first coupler mounted to the internal surface of the first side wall, a support arm having an arm length dimension between proximal and distal ends, the proximal end mounted to the first coupler adjacent the internal surface of the first side wall for rotation about a first vertical axis and a tablet member supported at the distal end of the support arm for rotation about a second vertical axis through a second range of motion with respect to the support arm.

Personal workspace assembly

A chair assembly includes an arm assembly that includes an armrest supported by a vertically adjustable support assembly and an arm base, where the arm base extends at an acute angle with respect to a longitudinal centerline of the chair assembly, an upholstery arrangement including a ring member attached to a cover, where the ring member includes a plurality of reliefs having a width that reduces as the ring member is wrapped about a shell member of the chair assembly, and a control arrangement having a biasing member that moves through an arcuate path as the biasing member is adjusted between varying bias settings.

Chair assembly with upholstery covering

A chair assembly includes a four-bar arrangement that includes a lower end and an upper end where the upper end is adjustable between a raised position and a lowered position, and an arm rest assembly adapted to support the arm of a seated user thereon and supported on an upper end of the four-bar arrangement, wherein the lower end of the four-bar arrangement is pivotably supported from an arm support structure for pivotable movement about an arm pivot axis, such that the upper end of the four-bar arrangement is movable between a first position and second position located laterally outward from the first position, and wherein the arm pivot axis is angularly offset from a vertical axis.

Chair arm assembly

A lounge assembly comprising a lower wall assembly including first and second substantially planar wall sections, the first and second wall sections forming first and second internal surfaces, respectively, that form an angle and at least in part define an assembly space, a lounge chair assembly including a seat and a backrest, the seat including a front edge portion and the backrest including first and second side edges, the lounge chair assembly mounted at least in part within the assembly space with the seat at a first height with a front surface of the backrest facing away from the first internal surface and the first side edge spaced apart from the second internal surface and a worksurface member having a flat and substantially horizontal tabletop surface and a circumferential edge that defines a tabletop shape, the worksurface member supported within the assembly space at a second height above the first height of the seat with a rear portion thereof extending between the first side edge and an adjacent portion of the second internal surface.

A chair assembly includes a back support arrangement including a back support arrangement, a seat support arrangement and a four-bar arrangement that includes a rearward end and a forward end that is adjustable between a raised and lowered positions, and an arm rest assembly adapted to support the arm of a seated user thereon and supported on the forward end of the four-bar arrangement, wherein the rearward end of the four-bar arrangement is pivotably supported from an arm support structure for pivotable movement about a substantially vertical pivot axis such that the forward end of the four-bar arrangement is moveable between a first position and second position located laterally outward from the first position, and wherein the substantially vertical pivot axis is located forwardly of a rearmost edge of an upwardly-facing surface of the seat support arrangement.

A chair assembly includes a back support arrangement that includes a back frame member and a forwardly-facing surface configured to support a user, a four-bar linkage assembly including a first linkage member, a second linkage member, a third linkage member and a fourth linkage member each pivotably coupled to one another such that the four-bar linkage assembly includes an upper end that is adjustable between raised and lowered positions, and an arm rest assembly supported on the upper end of the four-bar linkage assembly, wherein a lower end of the four-bar linkage assembly is pivotably supported from an arm support structure for pivotable movement such that the upper end of the four-bar linkage assembly is movable between a first position and second position located laterally outward from the first position, and wherein the fifth pivot point is located forwardly of the back frame member.

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.

Table top

A chair assembly includes a four-bar linkage assembly including a first linkage member, a second linkage member, a third linkage member and a fourth linkage member each pivotably coupled to one another such that the four-bar linkage assembly includes an upper end that is adjustable between raised and lowered positions, and an arm rest assembly adapted to support the arm of a seated user thereon and supported the upper end of the four-bar linkage assembly, wherein a lower end of the four-bar linkage assembly is pivotably supported from an arm support structure for pivotable movement, such that the upper end of the four-bar linkage assembly is moveable between a first position and second position located laterally outward from the first position and wherein the arm support structure is fixed with respect to the seat support structure.

A chair assembly includes a four-bar linkage assembly including a first linkage member, a second linkage member, a third linkage member and a fourth linkage member each pivotably coupled to one another such that the four-bar linkage assembly includes an upper end that is adjustable between raised and lowered positions, and an arm rest assembly adapted to support the arm of a seated user thereon and supported the upper end of the four-bar linkage assembly, wherein a lower end of the four-bar linkage assembly is pivotably supported from an arm support structure for pivotable movement, such that the upper end of the four-bar linkage assembly is moveable between a first position and second position located laterally outward from the first position.

A chair assembly includes a base structure, a seat support structure movably coupled to the base structure, an upwardly-extending back support structure movably coupled to the base structure, wherein the back support structure is adapted to move between an upright and reclined positions, wherein the back support structure is operably coupled to the seat support structure, a flexible shell structure defining a forwardly-facing surface forming a lumbar support, wherein the flexible shell is movably coupled to the seat support structure, and a resilient member generating a variable compressive force acting on the flexible shell structure in a manner that tends to cause a curvature of the back support structure to increase, and wherein the compressive force decreases as the back support structure moves from the upright position to the reclined position.
