A power shop stool that is battery powered and is a personal lifting device. The combination of components leads to a small compact device and allows a worker to adjust the seat height from 6″ to 24″ from floor lever in a vertical up and down fashion and it has the capability of stopping anywhere in between 6 inches and 24 inches.

A spring mechanism for a chair or a stool includes a base mount connected to a base and a seat mount connected to a seat. Two swing arms are arranged above one another. The two swing arms include a lower swing arm and an upper swing arm. Each of the two swing arms is pivotally connected to the seat mount and pivotally connected to the base mount. A spring is provided and arranged to generate an upwardly directed force onto the seat.

A collapsible and portable seating apparatus may include a seating assembly and a media mast with at least one image generation device. The seating assembly may be collapsible via at least one linkage assembly or pivot assembly, and portable via at least one wheel assembly. The media mast may be couplable to the seat assembly and removable to be set on a ground surface. The media mast may be portable when coupled to the seating assembly and/or separately portable in a hand-truck configuration when removed from the seating assembly. The media mast and/or the seating assembly may include components to provide increased stability and resistance against external and internal forces, where the components are deployed when the media mast is on the ground surface or the seating assembly is unfolded. A canopy may be couplable to the seating assembly.

A height adjusting mechanism for a dentistry stool comprises a support member, a movable height adjusting assembly and a pushbutton actuator. The support member is coupleable to the stool adjacent a seat of the stool. The movable height adjusting assembly is selectively movable up and down relative to the support member. The pushbutton actuator is positionable on a side of the movable height adjusting assembly adjacent a seated user, and is manually actuatable by the seated user to release the movable height adjusting assembly from a locked position at a current height to allow the movable height adjusting assembly to be moved to a new height. The height adjusting mechanism can be implemented to provide a height-adjustable seat back and/or a height-adjustable torso bar.

A packable chair is provided that is transformable between multiple configurations, including a storage configuration and a chair configuration. In the storage configuration, the portions of the packable chair are arranged and fastened to define an enclosed volume in which containers and other items can be stored. A user can wear the packable chair like a backpack in this storage configuration to transport the contents from, for example, a car to a location on a beach. Then, the contents can be removed from the enclosed volume, and the portions can be rearranged to form the chair configuration where a user can lounge and access the contents of the containers. The chair is also capable of achieving a travel configuration in which the chair can be worn as a backpack for convenient transportation without stowing a user's items.

An extendable seating interconnected mechanism and a seating supporting frame, including an interconnected assembly, a seating frame, and a backrest mount, wherein the backrest mount is rotatably connected to the interconnected assembly and the seating frame, respectively; the interconnected assembly includes a mounting plate and a driving link, wherein the mounting plate includes a lateral-plate part and a supporting part; the driving link is rotatably connected between the seating frame and the lateral-plate part; an end of the supporting part is connected to the lateral-plate part; and an opposite end of the supporting part is rotatably connected to the backrest mount. The interconnected mechanism and the seating supporting frame optimize and simplify the structure, leading to a compression of the height of the seating supporting frame; different seating positions may be adjusted smoother by connecting the extendable and retractable footrest mechanism and interconnected assembly, which improves the seating comfort.

A stool includes a base with a post extending therefrom. A seat is connected to a distal end of the post. In some configurations, the seat may be configured to act as a deployable back rest. A deployable anti-fatigue mat is connected to the base. In some configurations, the deployable anti-fatigue mat is attached to the base via a hinged connection. In some configurations, the deployable anti-fatigue mat is attached to the base with a sliding connection that allows the deployable anti-fatigue mat to slide out from the base.

Shock and vibration mitigation baseplates and related manufacturing methods. A shock and vibration mitigation baseplate includes a mounting frame configured for placement between a console operator chair and a rigid floor surface, and one or more viscoelastic polymer shock absorption and vibration dampening pads. The mounting frame houses the one or more viscoelastic polymer shock absorption and vibration dampening pads therein.

An adjustable and angled seat assembly having a base supportable on a ground surface, a wedge support member with a wedge length separating the front and rear ends thereon and a wedge height separating upper and lower ends thereon, with the lower end directly coupled to a support plate and tapering in the wedge height spanning along the wedge length to define a wedge angle θ defined by the upper and lower ends of the wedge support member. The assembly also includes a seat cushion having a seat-support surface disposed above the base and a seat-support angle relative to the base support plane and a lower surface directly coupled to the upper 704 of the wedge support member and a chest cushion having a chest-support surface disposed above the seat-support surface, coupled to the support plate, and disposed at an at an acute angle with respect to the seat-support surface.

An apparatus for mounting an attachment to a seat assembly including a seat mounted on a base includes a substantially planar, substantially rigid mounting plate configured to mount between the seat and the base, a first portion of the mounting plate engaging a plurality of threaded fasteners between the seat and the base, a second portion of the mounting plate extending beyond a perimeter of the seat, and an attachment attached to the second portion of the mounting plate such that the attachment does not interfere with a movement of the seat.
