You may have probably seen how some furniture pieces can be somewhat used for other purposes. This includes chairs used temporarily as tables or maybe even shelves if they can be stacked (assuming they are of the same design and make).
Hence, the Onenesss Furniture System should provide that said solution, pieces made from lightweight birch plywood, something which allows it to be easy to lift and stack while providing the necessary functionalities that people would be needing.
Once stacked, they can be used as reliable storage systems. Holes and hardware are likewise present to easily snap the said pieces, a system credited to Hironori Tsukue and Kyuhyung Cho.
