Storage of chairs when not in use, for instance in halls used by various groups, is a common problem which has been addressed by providing chairs that are stackable upon one another. Usually, this requires the chair to be composed of sloping legs and a sloping backrest, such that the seat of a lower chair can fit between the legs of an upper chair, and the backrest of the upper chair can rest on the backrest of the lower chair. It is desirable to be able to stack chairs with as small a vertical displacement as possible, usually limited by the depth of the seat, which is typically substantially horizontal. For instance, the base of an upper seat may sit (when stacked) on the upper portion of a lower seat. However, these chairs are usually mass produced and so designed to fit the average shape, which is not accommodating for a lot of people. The present invention provides a chair where seat 13 height, back 3 angle, seat 13 tilt and seat 13 roll are adjustable.

The present disclosure provides a multifunctional collapsible stool including a collapsible stool body. An upper end and a lower end of the collapsible stool body include an upper seat and a lower seat respectively, the collapsible stool body includes a cavity, and an upper cover capable of opening and closing the cavity is mounted on the upper seat. A rear end of the upper seat is rotatably connected to a backup ring located between the upper seat and the upper cover. A rear end of the upper cover is rotatably connected to the rear end of the upper seat. The multifunctional collapsible stool designed this way can be utilized as a closestool or a garbage bin with the upper cover opened in addition to being utilized as a stool. Further, the multifunctional collapsible stool may also be utilized for storage. With these functions, the use requirements of more consumers can be satisfied.

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.
