The base (10) has a rectangular shaped rotating base frame (11) comprising a top base element and a foot side. The foot side comprises a foot-side aperture (13) that is formed in diagonally directed wall surfaces (14-17). Side walls are formed from longitudinal sections (18-21) to a rectangular contour, and the corner regions are provided with the longitudinal sections by corner connectors (40, 42) in the wall surfaces. The corner regions are arranged against the corner connectors. The base frame is formed by plug connections from the longitudinal sections and the corner connectors.
