A sofa shelf includes a main body, a support member, a first clamping member, and a second clamping member. The main body is provided with a first surface and a second surface opposite to the first surface. The main body is further provided with a receiving groove located on the first surface. The support member is disposed on the first surface and is movably connected to the main body. The support member is provided with a placing groove arranged obliquely relative to the horizontal plane. Both the first clamping member and the second clamping member are disposed on the second surface. The first clamping member and the second clamping member are rotatably connected to the main body, respectively. Rotation directions of the first clamping member and the second clamping member are opposite.

A modular attachment system may be provided with the ability to rapidly interchange different peripherals and accessories at different points where modular receivers have been installed. One or more modular receivers may include one or more quick-connect receptacles adapted to receive corresponding one or more quick connectors of one or more peripheral adapters to quickly connect and disconnect the modular peripheral adapters to facilitate rapid reconfiguration of chairs, desks, tables, or other furniture for different applications. A variety of peripherals and accessories can be attached to one or more modular peripheral adapters to create peripheral assemblies that can be rapidly interchanged by rapid connection to or disconnection from any installed modular housings to reconfigure furniture for different applications. The modular receivers may be attached to a desk, table, or other furnishings or manufactured as a part of office, computer, or gaming chairs, desks, tables, or other furnishings.

A modular chair assembly includes a seat member and at least three support leg units. The seat unit includes a seat member which has a lower surface and an upper surface opposite to the lower surface. Each of the three support leg units is detachably mounted to the lower surface of the seat member, and includes an inner axle and a hollow tube sleeved on the inner axle. The inner axle and the hollow tube are made of different materials to permit the inner axle to have a larger anti-bending strength than the hollow tube. The inner axle includes a bottom end surface for being supported on the ground.

A stackable molded plastic chair has a removable cup holder that may be placed on the top surface of a chair arm for use or attached to the underside of the chair arm for storage. The cup holder has an inverted U-shaped body that fits over a chair arm and a cup receiver that is connected to that body. There is a post that extends from the bottom surface of the chair arm and is sized and configured to fit through the hole in the cup receiver and create a snap-fit. The cup holder may also have a cell phone pocket at either side of the inverted U-shaped body.

Powered chairs, assemblies for use in the powered chairs, and components for use in the assemblies are provided. Electrical systems for use in the powered chairs, and components for use in the electrical systems are provided. Control systems and methods for operating powered chairs are also provided. Any given chair may be locally and/or remotely controlled.

A chair and chroma key photography backdrop assembly leverages the effect of chroma key photography with a collapsible chroma key panel integrated directly into a chair on which an actor sits during broadcast or video conference. The chair has at least one accessory retention arm that forms a cavity sized and dimensioned to retain broadcast equipment, including cameras and sound systems. The chair also has a shock absorber to absorb shock impulses from the actor who is sitting on the chair. Chroma key photography software in the cameras separate the solid color of the chroma key panel from the actor sitting in the chair, and replaces the solid color background of the chroma key panel with a virtual image or video and also separates the actor from the background, such that the actor appears to be in front of a virtual image or video. By deploying the chroma key panel from the chair, stowage, mobility, and efficiency are enhanced during video production.

There is disclosed a portably suspended retractable shelf for storing furniture-side items that includes a horizontal platform having an inner portion and an outer portion. In various embodiments, the inner portion is adapted to be slidably captured between an upper cushion and a lower supporting structure. At least one of a projector insert rotationally adjustable to a plurality of orientations and the following upward-facing compartments is disposed on the outer portion of the horizontal platform and is accessible to a user on the furniture: a collapsible basin, a hanging flexible pocket, and a foldable box. A cutout hole is configured to hold the projector insert or the compartments in a suspended configuration through the shelf. A downward-facing sliding drawer compartment is mounted and/or supported underneath the outer portion of the shelf. A storage container extends from a leading surface of the portable suspended retractable shelf. Other embodiments are also disclosed.

Powered chairs, assemblies for use in the powered chairs, and components for use in the assemblies are provided.

The present invention relates to an adjustable stadium seat table. The adjustable table comprises a tray, a trey bracket, riser assembly, a horizontal assembly, a seat bracket and a 90 degree angle bracket. The horizontal assembly comprises an outer tube and an inner tube. The seat bracket is configured to hold the outer tube of the horizontal assembly underneath a seat. The tray of the adjustable table includes a slot and an opening. The slot on the tray accommodates a cell phone and the opening holds a cup comprising a drink. The tray is engaged to the inner tube tray via the tray bracket, wherein the tray bracket is bonded to the tray underneath. Further, the tray bracket enables the tray to rotate at 90. The tray and the riser assembly are stored under the seat and is retrieved by arena personnel once the event is over.
