On an article of furniture, a bearing assembly is disposed between an elongate central structure and a seat, which permits rotation between the seat and the base. A tablet is provided, which is connected to a tablet arm with a first cylindrical member, and the tablet arm is connected to the elongate central structure of the base with a second cylindrical member. The second cylindrical member is disposed around the elongate central structure with a flange at the upper end thereof. The bottom of the seat has a lobed friction bushing disposed such that the flange of the second cylindrical member contacts the lobed friction bushing and frictionally resists rotation of the tablet arm as the seat rotates 360 degrees relative to the base, leading the tablet to follow the seat as it rotates. A lobed friction bushing is also provided.

An adjustable chair frame with a back and seating surfaces that flex to conform to the shape, weight and movement of an occupant is disclosed. The chair form and proportions provide for a recumbent position that disperses the weight of the occupant more evenly, thereby reducing external and internal physiological point loading. The form also provides ergonomic articulation to minimize internal physiological stresses such as neck/back vertebral compression. Eccentric connections driven by a motor assembly allow positioning adjustment of the components of the chair. Additionally, an air pump assembly may be included to automatically adjust one or more air bladders provided on the interior of the chair frame.

The movable tablet includes a shaft fixed to an armrest and having a radial pin hole. A connecting seat has a first connecting portion toward the shaft and a second connecting portion. The first connecting portion is axially rotatably connected to the shaft. The second connecting portion has a through hole axially corresponding to the pin hole. A pin passes through the through hole and the pin hole to prevent the first connecting portion from rotating relative to the shaft. A tablet is rotatably connected to the second connecting portion. A releaser is disposed on the tablet to make the pin escape from the pin hole when the tablet is horizontally rotating so that the tablet can be turned vertically.

Collapsible holder for folding chair is set in a chair arm and the 3-D chair arm plane. The holder holds a cup or a cell phone (shape dependent, round or rectangular). The holder has a moveable member and a stationary member. The moveable member has a bottom plate, two or more upstanding legs and the legs have tabs. The stationary member has an upper lip, side wall(s) and retainers for the legs. The legs slidably move in the stationary member retainers such that in a collapsed mode, the bottom plate is closest to the lip and the holder is encased in the 3-D chair arm plane and, in the expanded mode when the tab acts as a stop against the retainer and the bottom plate is farthest away from the top surface of the chair arm and the lip, thereby enabled to hold a cup or cell phone.

Provided is a storage mechanism for a seat table enabling improved handleability at the time of storage with a relatively simple configuration. One aspect of the present disclosure is a storage mechanism for a seat table used by combination with a seat. The storage mechanism for the seat table includes a held portion provided to the seat table, and a holding portion provided to a storage portion where the seat table is stored. The held portion includes at least one attracted magnet. The holding portion includes at least one attracting magnet attracting the at least one attracted magnet, and at least one repelling magnet repelling the at least one attracted magnet.

Described are support surfaces (such as passenger seat tray tables) that have a pivot about which the support surface is rotatable. The pivot can be coupled with a track and movable relative to the track to adjust a deployed height of the tray table, such as among a stowed position along the seat back in which the pivot is retained at a first height; a first deployed position in which the pivot is retained at a first height and the support surface is oriented for receiving and supporting items; and a second deployed position in which the pivot is retained at the second height and the support surface is oriented for receiving and supporting items.

A cup holder comprises a body configured to receive a cup, and a generally planar support extending from the body, the generally planar support insertable between a seat and an underlying structure supporting the seat such that the cup holder is removably secured between the seat and the underlying structure supporting the seat by friction and at least one of a weight of the seat and a weight of a user sitting in the seat
