An adjustable chair comprising a seat part, a seat back disposed along one side of the seat part, the seat back being configured for supporting at least a person's back or shoulders, a chair base configured for being placed on a floor, at least one adjustable chair feature including a motor capable of being selectively controlled and driven so as to adjust at least one of: the rotation or tilt of the seat part, a vertical distance between the seat back and the one side of the seat part, an angle position between the seat back and the seat part, and a distance between the chair base and the seat part.

A system and method establishing control of affordances at a workstation. The method includes the steps of storing affordance preferences in a database for a plurality of portable affordance settings that may be present at a workstation, detecting a subset of affordances present within a first zone associated with the workstation, for each detected affordance in the subset, identifying an affordance setting in the database indicating a user preference, and automatically controlling settings of at least each of the detected affordances in the subset to match the user preferences for the detected affordances.

A retractable seat assembly which can be attached to a vertical structure and which, in the upright position, presents a profile which is relatively thin and in any event poses virtually no impediment to going very close to the vertical structure. The retractable seat assembly having a rear support, a seat, a front support, and a biaser which releasably biases said seat to the generally upright position.

A mechanism for an office chair is structurally particularly simple and consequently comparatively inexpensive, but nevertheless extremely variable. Both the seat support and the backrest support are articulated by way of a common pivot axis. The seat support is connected in an articulated manner to the base support by way of at least one pivot bolt and is pivotable relative to the base support. The backrest support is connected in an articulated manner to the base support by way of the at least one pivot bolt and is pivotable relative to the base support.

A bathing chair assembly for sitting level on an uneven surface includes a chair that may be positioned in a shower thereby facilitating the chair to support a physically disabled user in the shower. A plurality of legs is provided and each of the legs is removably coupled to the chair. Thus, each of the legs may support the chair in the shower. Each of the legs is positioned at a selected height with respect to the chair. Thus, the chair may sit level on an uneven surface.

Novel sit-stand seating devices, more particularly, to sit-stand seats or stools that can tilt forward to provide balanced support for seated to near-standing postures and methods of their use are disclosed. The sit-stand devices are useful, inter alia, to provide stabilized worker positioning to carry out a task for a range of sitting through standing postures in an environment associated with a task for a worker in need thereof.

A chair footrest ring positioning structure includes a guide region tilting downward and concavely disposed on an outer surface of any one side of the lower segment of the tightening case, one or more anti-slip pads fixed inside an internal space of the tightening case, one or more grooves concavely disposed at a periphery of the tightening case, to facilitate insertion of a middle pipe of the chair, and a sleeve corresponding in shape to the middle of the footrest ring fitted around the tightening case. One or more bumps extending from an inner side of the sleeve are inserted into the grooves of the tightening case, respectively. When the middle pipe is rotated to move the tightening case by a predetermined distance, the guide region undergoes a displacement to drive insertion of the bumps, thereby pushing the tightening case inward.

The invention is directed to a base for pieces of furniture having at least one supporting column structure. The base comprises a central hub receiving the lower end of a column and a number of arms radiating from the hub. The object of the invention is to provide a furniture base which allows varying its height. This is accomplished by changing the angle between hub and arms, or by shifting the points of attachment of the arms on the hub in the vertical direction.

A structure for chair backrest is disclosed. The chair includes a first support frame, a second support frame coupled to the first support frame, a seat section arranged between the first support frame and the second support frame. The first support frame includes a backrest mounted thereon. The first support frame includes a lower frame section and an upper frame section. The lower frame section and the upper frame section include, mounted therebetween, a supine inclination assembly that upon receiving a force acting thereon takes a movement for achieving an predetermined angle of supine inclination. In this way, easy adjustment of the angular position of the backrest may be achieved for comfortableness of the user, and excessive inclination that causes potential risk can be avoided so as to improve the utilization of the backrest of the chair.
