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 chair assembly includes a back support arrangement including a back support arrangement, a seat support arrangement and a four-bar arrangement that includes a rearward end and a forward end that is adjustable between a raised and lowered positions, and an arm rest assembly adapted to support the arm of a seated user thereon and supported on the forward end of the four-bar arrangement, wherein the rearward end of the four-bar arrangement is pivotably supported from an arm support structure for pivotable movement about a substantially vertical pivot axis such that the forward end of the four-bar arrangement is moveable between a first position and second position located laterally outward from the first position, and wherein the substantially vertical pivot axis is located forwardly of a rearmost edge of an upwardly-facing surface of the seat support arrangement.

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 salon treatment assembly (10) for use by a user during a salon treatment, comprises a foot bath (16), a salon chair (14), and an adjuster assembly (20). The salon chair (14) supports the user during the salon treatment and is coupled to the foot bath (16). The salon chair (14) can have a chair body (31) including a seat support (28), and an arm rest (32A) that is movably coupled to the seat support (28). The adjuster assembly (20) selectively moves the arm rest (32A) relative to the seat support (28) such that the salon chair (14) is alternatively positioned in a closed configuration, wherein the arm rest (32A) is positioned directly adjacent to a forward portion (28A) of the seat support (28), and an open configuration, wherein the arm rest (32A) is not positioned directly adjacent to the forward portion (28A) of the seat support (28).

A seating unit component assembly comprises a support component that includes a first surface adapted to abut a seated user, a second surface opposite the first surface, a first end surface, a second end surface opposite the first end surface, and a pair of side surfaces extending between the first and second end surfaces, and a cover having a plurality of sides that cooperate to form an interior space that receives the support component therein, wherein the cover includes a first portion comprising a non-fabric substantially flexible thermoplastic material covering at least a portion of at least one of the side surfaces of the support component, a second portion comprising a fabric covering at least a portion of the first surface and at least a portion of the first end surface of the support component, and a third portion comprising a substantially rigid overlay covering at least a portion of the second end surface and at least a portion of the second surface.

An armrest, in particular for an office chair, achieves improved handling and adjustability in an individual and in a particularly variable manner by providing a preferably height-adjustable armrest column, an arm support carrier which is mounted on the armrest column and which is rotatable about a first rotational axis, and an arm support which is mounted on the arm support carrier. The arm support is rotatable about a second rotational axis and is displaceable in a linear manner relative to the arm support carrier. The two rotational axes are spaced apart from one another.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a chair for assembly by a user. The chair for assembly by a user may include a bracket configured to releasably couple an arm rest assembly to a chair seat and facilitate adjusting a width for the arm rest assembly relative to the chair seat.

A chair seat is provided for combining with two armrests. Each armrest includes a crossbar. The chair seat includes a base and two clamping devices. The base includes at least one armrest slot and two mounting holes. The armrest slot is adapted for inserting the crossbar, and the mounting hole is in communication with the armrest slot. The two clamping devices are separately installed within the two mounting holes. Each clamping device includes a mounting base, a clamping element, an operating element, and a transmission element. The mounting base is affixed within the mounting hole and features an installation slot on one side. The clamping element is installed within the installation slot, facing the crossbar. The operating element is situated on the opposite side of the installation slot relative to the mounting base. The transmission element connects the clamping element and the operating element. The operating element is suitable for driving the transmission element, which in turn moves the clamping element toward the crossbar, thereby securing it.

A chair equipped with shoulder supporter is provided. The chair equipped with shoulder supporter can obtain an effect of attitude remedy by reducing the pressure applied to the spine and by inducing an upright attitude of erecting the waist vertically through a shoulder supporter which is connected to a hip supporter through a base. The shoulder supporter comprises an armpit supporter provided above a vertical supporter. The chair equipped with shoulder supporter can maximize convenience and enable the multi-purpose use by selecting the use and non-use of the arm supporter or the shoulder supporter with the direction change through up-down or forward-rearward direction rotation of the arm supporter or with the folding of the armpit supporter through a rotation shaft.
