A buoyant pool lounge chair frame and buoyant pool lounge chair using the same are disclosed. In one embodiment of the buoyant pool lounge chair for supporting a person while the buoyant pool chair is floating in water, frame members collectively form an open chair frame including a back frame and leg frame pivotally coupled thereto. Buoyant cushions are attached to the frame members to form a chair seat, a backrest, and a leg rest. A pair of rear pivotal coupling and clutch assemblies are coupled to the seat frame and to the back frame to adjust and fix the angle of recline of the back frame relative to the seat frame. Similarly, a pair of front pivotal coupling and clutch assemblies coupled to the leg frame and to the back frame to adjust and fix the angle of extension of the leg frame relative to the seat frame.

A seat, particularly for video games, includes a collapsible frame which carries a seat surface and a backrest. The frame includes a first part carrying the backrest and a second part configured to carry a console for a steering wheel or joystick for controlling a video game. These parts are connected pivotally to each other by a hinge. The hinge includes a first load-bearing body on which the first frame part is mounted, and a second load-bearing body on which the second frame part is mounted. The hinge has locking means for fixating the first and second frame parts in a desired position relative to each other. A hinge for application in such a seat.

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 modular wall may include one or more units. Each unit may include a telescopic member having an inner end and an outer end. The telescopic member may include a base, located at the inner end; a capital, located at the outer end; and a shaft disposed between the inner end and the outer end. The shaft may include one or more sections. Each shaft section may include an outer circumference, the outer circumference of each shaft section may decrease from the outer end to the inner end.

A chair can be configured for synchronized movement with visual content, such as a video game or movie, presented on a display. The chair can include a seat portion. A plurality of actuators can be operatively positioned to cause a movement of the seat portion. The actuators can include one or more shape memory material members. Each of the actuators being configured such that, when an activation input is provided to the one or more shape memory material members, the one or more shape memory material members change from a first configuration to a second configuration and cause the actuator to morph into an activated configuration. One or more processors operatively connected to selectively activate one or more of the actuators by causing the activation input to be provided to the one or more shape memory material members of at least one of the actuators.
