A chair having a separately configured seating assembly and backrest that move together upon reclining movement of a user. The seat assembly can be pivoted between a lowered, seating position and a raised, nesting position. The backrest can be pivoted between an upright position and a reclined position. The seat assembly includes a seat that is movable along seat frame sub-assembly that includes a pair of glide tracks upon the reclining movement of the backrest. A bias member of the seat assembly urges the seat into a retracted position and the backrest into an upright position. The seat assembly is pivotally mounted to the support frame of the chair such that the entire seat assembly can be pivoted to a raised, nesting position. The seat assembly can also be pivoted to a lowered, seating position to allow multiple chairs to be stacked.

An article of furniture has retractable and extendable wheels secured beneath each leg. The mechanism for retraction and extension is accomplished by an activation means in mechanical communication with each wheel.

A wobble base provides a curved floor-contacting surface with one or more alignment posts that align the wobble base to the bottom of a seating platform and one or more holes separate from the alignment posts through which one or more fasteners may be placed to attach the wobble base to the seating platform, thereby providing a wobble stool. The wobble base can be configured to convert an existing stool into a wobble stool by replacing one or more floor-contacting members with the wobble base. In a second embodiment, a seating platform, such as a stool, is provided with both traditional floor-contacting members, such as feet or casters, and with a wobble base that allows the traditional floor-contacting members to be removed and replaced with the wobble base, and allows the wobble base to be removed and replaced with the traditional floor-contacting members.

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.

Furniture pieces which incorporate load-bearing or non-load bearing structures in which water or other material may be stored. By incorporating such storage capacity within furniture, a user may take advantage of space that would otherwise be unused or unusable to unobtrusively and conveniently store an emergency water supply or other desired material.

The embodiments relate to a geometric under structure, central and outer hub for a GFN plastic chair base. The geometric shape and dimensions are critical components to the overall strength of the chair base hub and arms when either vertical or rotational forces are applied at the central hub. The central hub is of sufficient thickness to maintain dimensional stability when the forces are applied. The overall geometry and material composition enable the hub area to be constructed with minimal plastic wall thickness while optimizing the physical strength of the article and facilitating high production rate.

Convertible chairs that can be converted to and from an open chair configuration to a box or table configuration for storage and protection of the interior portions is provided. The convertible chairs can have include one or more of a sunshade, adjustable foot rest, legs, wheels, and can in some embodiments be a reclining chair. In some aspects, a cover portion can be used to cover a portion of the interior portions of the chair when the convertible chair is in a box configuration, and be folded and retracted into a pocket of the convertible chair when in an open chair configuration.

A patient support apparatus includes a frame, a stationary member mounted relative to the frame, a movable member having a pivot member rotatably mounting the movable member about the stationary member, and a fastener securing the pivot member to the stationary member. The patient support apparatus also includes a joint between the pivot member and the stationary member, which is configured to apply a tension force on the fastener.

An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. A method for using a stool can involve rotating armrests of the apparatus from a stowed position to a deployed position. The armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool.
