Abstract: Devices, systems, and methods for supporting the body of user are described. Devices, systems, and methods can employ a plurality of cells where each of the cells within the plurality of cells can comprise a bladder containing air or another compressible fluid supported by a base that forms a fluid-tight seal with the bladder The base and bladder can be constructed and arranged so that the bladder forms a rolling diaphragm portion with the base. The height and/or applied pressure in response to an applied load of such bladder may be adjustable substantially independent of the crosssectional shape and dimensions of the bladder. Each of the cells within the plurality of cells which may be a subset or all of the cells of a given support, can also comprise, or otherwise be operatively associated with its own: pressure sensor, height sensor, or both, and/or controllable inlet/outlet valve(s).

Abstract: An electric plug system includes a stabilizing base constructed to stand on a horizontal floor surface, a vertical support element supported by and extending from the base and defining a vertical axis, and an electrical socket block coupled to a top portion of the vertical support element and supported thereby. The electrical socket block has a plurality of electrical sockets constructed to receive the plugs of the devices. Also, the system includes an electrical wire extending from the horizontal electrical socket block, down the vertical support element, and along or through the base and there-beyond, the electrical wire terminating in an electrical plug constructed to plug into the wall or floor electrical outlet. The system can include a device holder removably attached to the vertical support element. The base can include a first base portion and a second base portion removably attached to one another.
