A chair (1) for relieving back pain of a user, with a seat surface (2) and a backrest (3), wherein a backrest angle (4) between backrest (3) and seat surface (2) is adaptable. At least one support element (5) for supporting the upper body of the user, when the latter is in an intended sitting position, is arranged on the backrest (3), wherein the support element (5), in the intended sitting position, can preferably be arranged, or is arranged, under the armpits of the user. The support element (5) is designed in such a way, and arranged on the backrest in such a way, that it can be moved by the user in order to obtain a desired support of the upper body at a predefined backrest angle (4) while he is in the intended sitting position.

A work chair includes a chair body, a plurality of wheel sets mounted at the bottom side of the chair body, a seat cushion mounted at the top side of the peripheral wall of the chair body, two guide rails mounted at the chair body at one lateral side each defining a longitudinal sliding slot and locating notch in communication with the sliding slot, a tray, a pivot bolt pivotally connecting the tray to the sliding slots of the rail for allowing the tray to be moved along the sliding slots of the guide rails and having an engagement portion for selectively engaging in one locating notch of each guide rail to hold the tray positively at the selected elevational position for carrying tools.

A portable table assembly includes a table that may to support items. A plurality of fasteners is provided and each of the fasteners is movably coupled to the table. Each of the fasteners may be selectively coupled to a chair thereby facilitating the table to be accessible from the chair. Each of the fasteners is movably coupled to the table. Thus, the plurality of fasteners may accommodate a variety of chair sizes. A first coupler is attached to the table. The first coupler may engage an item thereby facilitating the table to be selectively coupled to the item. A leg is hingedly coupled to the table an the leg is selectively positioned in a deployed position. Thus, the leg may abut a support surface thereby facilitating the table to be horizontally oriented with respect to the support surface.

A desk (10, 10a, 10b) having a top section (14) including a central hole (12) wherein a user of the desk may sit and a gap (26) where they may enter. The top section has multiple sub-sections (20a-c) that assemble so the top section is substantially round and forms a top side whereupon objects may be placed on the desk. A central section (16) includes multiple uprights (30, 54) each having one or more wheels (46, 58) upon which the top section rotatably rests when the desk is assembled.

A method of remanufacturing a toner cartridge includes installing a modified end cap in which a portion of a drive assembly for an internal toner seal removal mechanism has been disabled. With the modified end cap installed, the toner cartridge may be post tested without removing the internal toner seal. When the post test is complete the modified end cap is removed and a non-modified end cap with a functional drive assembly is installed in its place.

A work and discussion space includes two installation blocks that are positioned opposite one another. Each installation block accommodates two people and includes a vertical partitioning structure, two seats positioned against the vertical structure and separated by at least one module for storing professional and/or personal accessories, and a work surface each associated with a seat. The worksurfaces are movable between a position that is distant from, and a position that is close to, the corresponding seat.

A set of modular classroom desks configured for outdoor use is presently described. Each classroom desk includes a bench seat; a table unit having a top surface; and first and second legs, each of which is coupled to both the bench seat and the table unit. The classroom desks of the set are configured to be releasably attached together in either a side-by-side orientation or a face-to-face orientation. In the side-by-side orientation, the top surfaces of the classroom desks form a planar tabletop surface, and the bench seats of the classroom desks form a planar seating surface. In the face-to-face orientation, the top surfaces of the classroom desks form a planar tabletop surface. In this manner, a number of classroom desks may be attached together, for instance to form a picnic table.

Mobile folding restaurant booth style benches are provided, which may be arranged in opposed pairs to form restaurant style booths. An individual bench incorporates a mechanism for shifting the weight of the bench between a mobile base, which may be supported by swivel casters, and a stationary base, which may be supported by non-slip feet, actuated by pivoting a bench seat down from a folded storage position to an unfolded seating position. The weight shifting mechanism may include an engagement member, which is initially spaced apart from an actuator at a folded angle of the seat, and which contacts and begins transmitting force and movement to the actuator at a partially unfolded angle of the seat. Preferably, the bench further includes a biasing component that biases the stationary base upward relative to the mobile base, a locking mechanism that resists a force provided by the biasing component to retain the bench seat in the unfolded seating position, contoured shells or other covers for the seat and a seat back, and a back panel extending vertically above the seat back.
