Reclaim the streets! Zuko is a free rental service for mobile street furniture that transforms unused public spaces into places to relax and socialize. Until now, conventional folding chairs have been used for this purpose – together with ante up, the design studio of Hauke Unterburg and Benedikt Stonawski, seating objects are now being designed according to ecological principles. In addition to the idea behind Zuko, first prototypes and the open design process will be presented.
