An adjustable chair, belonging to the field of office furniture, comprising a base frame. A chair back is disposed at the rear end of the base frame. A lifting assembly is disposed on the base frame and provided with a seat, and comprises a bottom frame and a top frame formed with sliding slots. The seat is disposed on the top frame and the seat angle can be adjusted. By adjusting the height of the chair through the lifting assembly and adjusting the rotation angle of the seat, users not only can stand and lean against the chair, but also can normally sit on the chair.

A deployable chair and desk assembly allowing for facile repositioning to different locations includes a chair and a desk. A pair of posts is engaged to and extends upwardly from a back of the chair. A canopy engaged to the posts shades the chair. A beam is engaged to and extends between the back of the chair and the desk so that the desk is positioned proximate to a front edge of the chair and provides a work surface for a user seated in the chair. Each of a set of ports is engaged to one of the chair and the desk and can operationally engage an electronic device. A solar panel is engaged to an upper surface of the canopy and is operationally engaged to the ports. The solar panel converts light into an electrical current to power an electronic device engaged to a respective port.

Here is described a piece of furniture, and particularly a sofa, that comprises a base and a seat cushion. The base comprises longitudinal structures; a pair of transversal structures mounted to the longitudinal structures; arms rotatively mounted to the transversal structures; and poles mounted to the arms. The seat cushion is adapted to be laid over the base. The poles are movable between positions providing therethrough one of: an adjustable support for the seat cushion; and an adjustable slope for the seat cushion. The sofa may further comprise mounting brackets mounted inwardly to the frame, each one comprising a mounting rod. Cushions of the sofa comprise a cushion body; and a pair of mounting braces extending from the cushion body and comprising a slit in which the rod is positioned as the cushion is rotated around the rod until the cushion stands in place.

The disclosure provides a telescopic structure, including a plurality of connecting pieces connected end to end; two adjacent connecting pieces are movable with respect to each other, and each of the plurality of connecting pieces includes a plurality of fixation mechanisms configured to keep the plurality of connecting pieces in an unfolded state. Also provided is a telescopic stool including a stool surface, a base, and the telescopic structure; the stool surface and the base are connected by the telescopic structure.

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.

A volumetrically efficient mechanism for raising and lowering sitting assemblies to provide ready access below them. A scissors assembly is selectively moved from a collapsible to an extended (raised) configuration by an electric motor with a telescopic arm that acts on hingedly mounted U-shape frames. The distal ends of the frames include wheels that ride over a lower support assembly. The telescopic arm is mounted to one of the distal upper member of the frames and the motor is rigidly mounted to the upper end of the other U-shape frame or to the lower support assembly causing them to selectively move between the two extreme configurations.
