Seat assemblies and methods for fabricating seat assemblies are provided. In one example, a seat assembly includes a seat frame and a seat cushion that is supported by the seat frame. The seat cushion includes a modular foam arrangement including a first modular foam section having a first interlocking feature and a second modular foam section having a second interlocking feature engaged with the first interlocking feature. An outer covering at least partially covers the modular foam arrangement.

A chair back assembly includes a back frame having a front surface and a rear surface and including a laterally extending cross member having opposite end portions, a back shell including a front surface, a rear surface positioned in front of the front surface of the back frame, a pair of laterally spaced side portions defining an opening therebetween, and a top portion extending laterally between and connected to the side portions, wherein the side portions are exclusively connected to the cross member at opposite ends of the cross member, wherein the connection between the side portions of the back shell and the end portions of the cross member are the only connections between the side portions of the back shell and the back frame, and a cover extending across the opening and connected to the side portions and the top portion of the back shell.

A chair component assembly includes a support component adapted to support a portion of a seated user, and a cover including a plurality of sides that cooperate to form an interior space that receives the support component therein, the cover further including a support component receiving aperture and a flap movable between an open position where the support component may be moved from an exterior of the cover to the interior space of the cover, and a closed position where the flap covers the support component receiving aperture, and wherein the flap is secured to the support component by a quick-connect fastener.

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 seat portion includes a first layer, a second layer, and a third layer that are stacked sequentially from the surface side to the inner side of the seat portion. The second layer has a higher stiffness than the third layer, and the first layer has a lower stiffness than the third layer. A pressure sensitive part has a pressure sensitive-part body arranged between the first layer and the second layer.

An apparatus for improving sitting posture has a pair of cushion members and a belt or strap connected to the cushion members for attaching the cushion members to a seat back at spaced locations thereon. The device is attached to a seat back so that the cushion members are positioned along or proximate respective vertical edges of the seat back, are spaced from one another and are located at substantially the same height or vertical distance from a horizontal buttocks support member attached to the seat back.

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.
