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.

A lounge having a matrix mat and a plurality of modules capable of being inserted into the matrix mat. The lounge may include a frame configured as a rigid frame, a modular frame, and combinations thereof. The modular frame may further include a tri-cable suspension. The tri-cable suspension may be attached to a dilator retractor mechanism. The modules may be a mushroom cap module, a spider spring module, a web module, a lighting module, an electronics module, and combinations thereof.

A foam seating article includes a layer of molded foam surrounding a hollow shell made of hard plastic. A fabric covering encloses the shell and molded foam. The foam seating article can take the form of a chair, stool, sofa, chaise lounge, bench or Ottoman. The hollow shell can be formed using blow molding, injection molding or by capping both ends of a tube with disks. Air pressure inside the airtight hollow shell prevents the shell from collapsing inwards under the weight of an occupant. Alternatively, the hollow shell of the seating article can be accessed through a removable lid. The seating article includes no wood or metal. The layer of molded foam includes sections of different foam types, such as high density (HD) foam, memory foam and latex foam. Molding foam around a hard plastic shell is simpler and less costly than making conventional metal or wood framed furniture.

A chair back assembly includes a substantially rigid back frame assembly, a back shell member operably supported by the back frame assembly and including a laterally extending top portion, a laterally extending bottom portion and a pair of longitudinally extending side portion extending between the top portion and the bottom portion and cooperating therewith to define an open space therebetween, wherein the pair of side portions are substantially rigid in a lateral direction, and wherein the back shell member is substantially rigid in a lateral direction and substantially flexibly resilient in a fore-to-aft direction, and a cover having a first surface adapted to support a seated user and a second surface opposite the first surface, wherein the cover is positioned over the back shell member to cover at least a portion of the open space.

Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies (145), with each spring assembly including at least one spring (134) and a spring cap (144, 150, 161, 164, 171, 184, 194, 204). Each spring cap has at least one first attachment fitting (168, 178, 174, 186, 196) and at least one second attachment fitting (169, 180, 176, 187) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.

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 control assembly includes a base structure having first and second pivot points spaced from one another, a seat support structure coupled to the first pivot point, a back support structure coupled to the second pivot point and adapted to move between first and second positions, wherein the base structure does not move as the back support structure moves between the first and second positions, and a control link pivotably coupled to the seat support structure for rotation about a third pivot point and pivotably coupled to the back support structure for rotation about a fourth pivot point, wherein the third pivot point is rearward of the fourth pivot point when the back support structure is in the upright position, and the third pivot point moves forward relative to the fourth pivot point as the back support structure moves from the upright to reclined positions.

A support surface, comprising a first, substantially planar rigid surface connected to a second substantially hemispherical, substantially non-rigid portion, wherein the support surface is arranged to be positionable in at least two orientations, wherein at least one orientation provides a substantially planar support surface, and at least one other orientation provides a seating surface.

A seat core member of a seat portion provided with the seat core member made of a hard synthetic resin foam and a cushion layer made of a soft synthetic resin foam and covering the seat core member is provided, and the seat core member includes a plurality of ridges extending in a rising direction of the seat core member in a rising portion of the seat core member being in contact with the cushion layer and opposing to calves of a body is formed.

A seating unit component assembly comprises a support component that includes a first surface adapted to abut a seated user, a second surface opposite the first surface, a first end surface, a second end surface opposite the first end surface, and a pair of side surfaces extending between the first and second end surfaces, and a cover having a plurality of sides that cooperate to form an interior space that receives the support component therein, wherein the cover includes a first portion comprising a non-fabric substantially flexible thermoplastic material covering at least a portion of at least one of the side surfaces of the support component, a second portion comprising a fabric covering at least a portion of the first surface and at least a portion of the first end surface of the support component, and a third portion comprising a substantially rigid overlay covering at least a portion of the second end surface and at least a portion of the second surface.
