Tojo High Stacker Shelving System. This high stacker by Dirk Frömchen for Tojo Möbel lives up to its unassuming name, as it is a brilliantly simple (almost) infinitely expandable system for storing books, files, and display items. And it does so without screws, drilling, or other bothersome DIY tasks. For vertical stacking, primarily extension elements are used – two side panels with a shelf. The top is capped with a cuboid base element featuring a bottom and a smoothly finished lid. The distinctly milled sides give the shelf a unique appearance, but they primarily serve to stabilize the loosely stacked individual elements. The bottom of an element is secured in such a way that it prevents lateral shifting of the element placed on top. Base element with doors. For those who prefer to stack a shelf or freestanding room divider with a closed front, thus avoiding the sight of too many items, this elegant variant is the way to go, featuring two doors that can be opened using milled handles.
