Abstract: A modular furniture system for open-plan offices includes a cable tower unit, a plurality of panel screens which are attachable to and detachable from the cable tower unit and a workstation surface. Adjacent panel screens define a workstation area when they are attached to the cable tower unit into which the workstation surface is moveable. The workstation surface is free-standing from the cable tower unit and the panel screens. In a further embodiment, two cable tower units may be attached together through their respective rear faces to form a single cable tower unit having four workstation areas.
