A lumbar support assembly for an office chair is presented herein. The lumbar support assembly includes at least one extension pad assembly which may be mounted to an existing lumbar support structure of an office chair. The extension pad assembly includes a base and a pad, wherein the base includes a recessed mounting structure disposed one side thereof. The recessed mounting structure is defined by a recessed surface at least partially surrounded by a retention wall, with the pad mounted to the opposite side of the base. One or more mounting clips extend from the retaining wall allowing the existing lumbar support structure to be snapped and engaged therein. With the extension pad assembly mounted in this manner, additional pressure and support can be added to the lumbar region of an individual seated in the chair.

The present invention relates to a cantilever seat cushion for reducing lower back strain, including: an inner pre-cut foam; an air tight shell that surrounds the inner pre-cut foam; an outer fabric cover that surrounds the air tight shell; an air valve that adjusts an incline angle of the cantilever seat cushion by deflating or inflating the seat in which the incline angle of the cantilever seat cushion is in a range from 10 to 25 degrees.

A cushion (10) device comprising: a planar support member (20) formed from a resilient material which defines a front (22), rear (24, 64) and two side portions (26) of the support member (20), wherein a recess (40) is provided at the rear (24, 64) portion of the support member (20) at a mid-position between the two side portions (26), and wherein the support member (20) includes two opposing wing members (42) extending laterally into the recess (40) towards the mid-position.

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 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 seat pad (10) of the present invention includes a placement surface (11). A lateral slit portion (15) which extends from an outer side of the seat pad (10) toward an inner side thereof is formed in a first lateral direction (B1) along the placement surface (11), and the lateral slit portion (15) is curved and thereby protrudes in a thickness direction (H) orthogonal to the placement surface (11).
