A chair having a chair back with an enlarged and curved seating surface is described. The raised seating surface has a front to back dimension (depth) substantially similar to its left to right dimension (width) approximately 0.80 meters. The seating surface is further curved upwardly on the left and right sides relative to the front to back center of the seating surface. In one variation, the radius of curvature pertaining to the curve is approximately 1.0 meters.

A portable seat and back cushion for posture correction. The device includes a seat member with an inflatable bladder or a foam insert and a back member that is foldably connected to the seat member. A customizable support member is disposed within the back member.

A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.

A folding chair includes front and rear supports that fold and/or retract into central beams to reduce the space occupied by the chair in a folded configuration. A backrest is coupled to the central beams with a hub that allows an angle of the backrest relative to the central beams to be selected and for the backrest to be folded flat relative to the central beams. One or more actuators and pin actuators may control the relative movements of the backrest, front support, rear support, and central beams.

An improved chair seat design is disclosed comprising a foam cushioning unit having top, middle, and bottom layers of foam secured together into a single unit. The bottom layer of foam includes a recess or slot sized to accommodate a void cell cushioning layer. The void cell cushioning layer is inserted into the recess: slot of the foam cushioning unit. Preferably, the void cell cushioning layer comprises an upper layer having an array of smaller cells with peaks pointing downwardly and pockets facing upwardly into the foam cushioning unit, and a lower layer having larger cells with peaks pointing upwardly and pockets facing downwardly relative to the foam cushioning unit. The foam cushioning unit with void cell cushioning layer inserted is then preferably attached to a contoured seat pan to form an improved office chair seat.

The present floor seat apparatus includes a base, a seat removably seatable in the base, and a tray engagable to the base. The base may be used as a seat by itself, with or without the seat and with or without the tray. The base includes a post. The seat includes a post through opening that engages the post and positions the seat in the seat receptacle of the base.

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.

An orthopedic device; the orthopedic device includes a cushion having a left side and a right side having different heights to level and correct a lateral pelvic tilt in a seated user. In one embodiment, the left side and the right side may each include pads for supporting respective buttocks of the seated user seated with lateral pelvic tilt. In another embodiment, the cushion may be used for supporting just one buttock of the seated user seated with lateral pelvic tilt. A method for diagnosing lateral pelvic tilt and for using the orthopedic device to correct the lateral pelvic tilt is also disclosed herein. The orthopedic device is useful for relieving, or at least substantially relieving, back pain and pressure associated with lateral pelvic tilt.

A folding chair includes front and rear supports that fold and/or retract into central beams to reduce the space occupied by the chair in a folded configuration. A backrest is coupled to the central beams with a hub that allows an angle of the backrest relative to the central beams to be selected and for the backrest to be folded flat relative to the central beams. One or more actuators and pin actuators may control the relative movements of the backrest, front support, rear support, and central beams.
