The present application relates to a shop chair with a seat cushion supported by a strong, light-weight base assembly with an elevated central hub that threadably receives a central column to adjust the height of the seat cushion. The base includes several vertically oriented thin plate legs that extend radially outward and downward from a central hub. The outer ends of the legs are joined by a stabilizing ring with a diameter larger than the seat cushion. Oversized caster wheels and the large footprint of the base provide a stable work platform. The seat cushion can be selectively lowered until the bottom of the central post is proximal to or contacts the ground. The chair and its base are particularly suited for work done closer to the ground.

The invention relates generally to a lightweight, collapsible, and portable wheeled seat, e.g., a wheeled office chair or stool, for travel, storage, and mobility. The seat includes a seat base member and a seat surface member collapsible between an open, extended position, which is configured to provide a seating surface, and a collapsed, closed position. The seat surface member includes a central seating surface member fixed to the seat base member that has an outer perimeter, and a pair of oppositely disposed and generally u-shaped seating surface members pivotally secured to the seat base member. Each of the generally u-shaped seating surface members include a pair of leg portions that extend from a base portion thereof, or an inward directed perimeter and a portion of each inward directed perimeter has a shape that substantially complementarily corresponds to a shape of a portion of the outer perimeter of the central seating surface member.

An electrically controlled chassis includes: a chassis body; an electrical control box, internally provided with an accommodation space; a drive motor, configured to control lift adjustment of the chassis of the chair and pitch adjustment of a backrest of the chair; a winding mechanism, connected to an output shaft of the drive motor; a first pull cord, reversely wound on the winding mechanism; a second pull cord, normally wound on the winding mechanism; a backrest adjustment mechanism, disposed on the chassis body, and fixedly connected to the other end of the first pull cord; and a chassis lift mechanism, disposed on the chassis body, and fixedly connected to the other end of the second pull cord.

Disclosed are a chair device and a star-shaped base (3) thereof, in particular capable of being used for office chairs, work chairs, stools or standing auxiliary devices, the star-shaped base comprising a center seat (4) and a plurality of extending arms (5) mounted on the center seat (4), wherein the extending arms (5) are used for the star-shaped base (3) to be placed on the ground, and at least one of the extending arms (5) is hinged to the center seat (4) and can rotate relative to the center seat (4). A chair seat of the chair device can rotate or swing, while parts mounted at an upper end of a chair column do not need to be modified, and particularly, a supporting structure, a chair support for the chair seat to be placed, and the chair seat itself do not need to be modified.

The invention is directed to a base for chairs or tables having at least one centrally located column structure. Specifically, the invention is directed to a base composed of several parts, comprising a hub and load-carrying arms radiating therefrom. According to the invention, each arm is separately manufactured and provided with a cavity at least at its proximal end and is individually joined to protrusions on the hub which are inserted into said cavities, and the joint between arms and protrusions is glued.

A stepstool includes a stool body and a stability extension. The stool body includes a top step and a support structure that supports the top step. The stability extension projects distally from a base portion of the support structure and extends distally beyond a distal edge of the top step. The stability extension is configured to be received in a toe-space at the base of floor-standing furniture, and the stool body is configured so that the distal edge of the top step can be positioned immediately adjacent to the floor-standing furniture, to provide mechanical interference and thus prevent tipping of the stool body when a user on the top step leans out of balance. Also, the sides of the support structure can be angled outwardly to provide a wider base portion for improved stability of the stool body.

Exemplary aspects of the present invention are directed to a reconfigurable dolly that may include a base, one or more base plates, that may be removable from the base and nest within the base, and one or more caster wheels connected to the base to allow for movement of the reconfigurable dolly relative to the surface on which the reconfigurable dolly may be positioned. The base of the reconfigurable dolly may be configured to be coupled to a base receiving tube. The base receiving tube may be configured for telescoping receipt of a seat receiving tube. The seat receiving tube may be telescopically positionable within the base receiving tube. The seat receiving tube may be configured for receipt and retention of an adjustable seat.

A connecting mechanism of a detachable chair foot, an assembling method thereof and a chair foot assembly are provided. The connecting mechanism is connected between the central chassis and a detachable chair foot, and includes a one-foot connecting arm connected to the central chassis and extends radially outward, a connecting groove including a transversal groove opening, and a longitudinal groove opening and operatively engaged with the one-foot connecting arm, two inner-convex locking portions respectively arranged on two opposite side groove walls of the connecting groove, two longitudinal locking groove bodies respectively arranged on the one-foot connecting arm; a concave-convex matching structure arranged on the one-foot connecting arm and in the connecting groove of the detachable chair foot. The chair foot assembly with the connecting mechanism not only can save transportation space and improve transportation efficiency, but also reduce the amount of assembly work.

A sidekick stool is provided, including a frame body, including at least two support portions which are spacingly arranged; a seat body, being disposed on the at least two support portions; and a rail assembly, fixed to the seat body for a receiving unit to slide therein.

A recliner furniture piece wherein the pair of oppositely disposed side arm sections or frameworks of the furniture piece have their forward end portions extended forwardly beyond the location at which the footrest is disposed when the footrest is located at its fully retracted position, and wherein the pair of oppositely disposed side arm sections or frameworks of the furniture piece have their rearward end portions extended rearwardly beyond the location at which the backrest is attached to the underlying actuator and linkage system. In this manner, the moment arms of the furniture piece are effectively increased while the moment arms of the fully extended footrest and fully reclined backrest are reduced such that the recliner furniture piece can withstand, accommodate, or tolerate increased weights or loads impressed upon the fully extended footrest and/or the fully reclined backrest.
