A mobile body unweighted sit and stand chair assembly prevents repetitive stress from sitting, standing, and lifting objects for long periods. The assembly provides a vertically, rotatably, and pivotally adjustable seat, a restrictive support padding that rotates from a support bracket to selectively support the spine or the pelvis, and a frame for structural integrity, mobility, and steering. The seat supports the buttocks and the ischium region of the pelvis, tilting forward up to 35 degrees to abut the pelvis against the support padding. This forward position maintains the spine in a straight posture and forces open posterior intervertebral disc space. The seat is supported by an adjustable rod that supports the weight of user while sitting, walking, kneeling, or lifting. A frame includes wheels that enable mobility and a brake. A first bracket enables feet to steer for hands-free maneuverability. A second bracket provides balance during kneeling and lifting.

A modular sofa assembly described herein includes a plurality of seating modules each having a seat section, a backrest section, and side edge surfaces. The backrest section includes first and second portions coupled for movement between a folded configuration and an extended configuration. An armrest module has an armrest side edge surface configured for mating engagement with a side edge surface of a seating module. The modular sofa is assembled by aligning connectors of the seating modules and armrest module, with each respective connectors slidingly engaged along an axis. After bringing the modules together, these connections are secured with the side edge surfaces in abutting engagement. The modular sofa further may include a power cradle mounted at the sofa's bottom surface. The power cradle includes a cubic power outlet near the front of the sofa, and power cable extending beyond the back of the sofa.

A foam-based seating furniture with an enclosure is provided. The foam-based seating furniture includes main body, a cutout opening formed in the main body, fitted fabric configured to encase the main body, and a removable nesting insert configured to friction fit within the cutout opening. The removable nesting insert can be inserted into the cutout opening, or removed, to provide a myriad of seating arrangements. The main body can be provided in a variety of geometries, including a square with a square removable nesting insert, a circle with a base and a circular removable nesting insert, and a hexagon having a circular nesting insert.

Joystick chair is an input device for interaction between the user and computer. It enables the movement of the user in games. The invention is used by placing feet on the platform (3) and sitting or leaning on the seat (23). Command for turning is achieved by rotating the seat (23), either to the left or to the right. Command for forward movement is issued by pulling the left or right controller (36, 41) with fingers, while the command for backward movement is issued by pushing the left or right controller (36, 41) away by palms. Control handles for lateral movement (49, 56) are separated from the forward-back controls that are located on the controllers (36, 41). Other commands are achieved with buttons on the left and right controller and they are accessible with thumbs. The software allows the modifications of all available actions of the invention.

A modular furniture assembly includes: a base member having a frame assembly, a transverse member having a frame assembly, a foot configured to contact a support surface, and a mounting platform having a plurality of apertures therethrough. The mounting platform is configured to be mounted on the base member frame assembly and the transverse member frame assembly, thereby connecting the frame assemblies. The foot is selectively mounted on the mounting platform, such that the foot is configured to contact the support surface when the modular furniture assembly is in an upright configuration. The mounting platform connects the base and transverse member frame assemblies together and also acts as a platform for receiving a variety of different types of feet.

A piece of seating and supporting furniture with or without an armrest, comprising an upright and a basic seat and supporting structure (seat and structure) arranged thereon such that it can be pivoted about at least one horizontal axis, wherein the seat and structure has a seat surface which, in a first end position of pivoting about the horizontal axis, is arranged substantially in a horizontal plane, wherein the seat surface, in a second pivoting end position, is arranged transversely to the horizontal plane, wherein the seat and structure has a supporting surface arranged on a side of the seat and structure spaced apart from the seat surface. In another embodiment, a first end of a spring is connected to the upright, a second end of the spring is connected to the seat and structure, and the spring assists pivoting of the seat and structure about the horizontal axis.
