Tojo Hochstapler is a freestanding shelving system that can be expanded horizontally and vertically without limits. The distinctly milled sides give the furniture its unique appearance and primarily serve to connect the segments to each other. By attaching the base slightly below the milling, lateral slipping is also prevented. The Hochstapler is made from melamine-coated MDF. For each vertical unit, you need a base module. The base module has a top and bottom and is always used as the top module. With the desired number of extension modules, the height can be expanded modularly. The base module can be used as a standalone piece of furniture, while the extension module cannot.
