A chair comprises a frame having legs, and a pair of uprights extending above the legs. A seat is carried by the legs of the frame, and a backrest is carried by the pair of uprights. A top bar is coupled between tops of the pair of uprights and extends above the backrest. A top cap is disposed on the top bar and covers an uppermost surface and uppermost perimeter edge of the top bar.

The present invention solves the problem of realizing a lighter cushion body that has ample cushioning properties when a person sits or lies thereon by: providing a plurality of rod-shaped or flat plate-shaped support bodies (2) comprising a synthetic resin foam that has a bending deflection amount of 20 mm or more as measured according to the method described in JIS K7221-2:2006 and a pressing force of 2-100 N at 20 mm of deflection, and legs (3) on which the support bodies (2) are placed or fixed; using the support bodies and the legs to form a space (5) that makes it possible to bend and deform the support bodies; and arranging the plurality of rod-shaped or flat plate-shaped support bodies (2) in a row so as to be deformable.

A vehicle seat comprises a seat cushion frame configuring a frame member of a seat cushion, and a seat unit that is supported by the seat cushion frame and on which an occupant sits, that has a higher seating face rigidity in a seat front-rear direction than a seating face rigidity in a seat width direction, and that has the seating face rigidity in the seat width direction set lower at a seat front-rear direction rear side than at a seat front-rear direction front side.

A shaped flexible hot-cure PU foam article, preferably mattress and/or cushion, may be obtained by reaction of at least one polyol component and at least one isocyanate component in the presence of at least one blowing agent and one or more catalysts that catalyze the isocyanate-polyol and/or isocyanate-water reactions and/or isocyanate trimerization, foam stabilizer, and further additives. The foam stabilizer may include at least one compound of formula (1)

A seating structure includes a base, a seat supported by the base, and a backrest supported by the base. The backrest includes a rear backrest section and a front backrest section coupled to the rear backrest section to define a gap therebetween. The gap extends around at least part of a perimeter of the backrest. The backrest further includes a fabric layer covering the front backrest section. A portion of the fabric layer is received in the gap.

A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is thicker and more rigid than the scrim sheet.
