The Konstantin chair for chef Konstantin Filippou's five-toque restaurant in Vienna is made of sustainable material. The armchair was made from local materials that come from a radius of around 100 kilometers (of Vienna).
The conceptual idea comes from the special details that have to do with grips and handles, such as pans and knives. These ideas found their place in the leather patches of the armrest, the foot details, and the covers to protect these areas.
The main focus was also on sitting comfort and special details like the integrated padding in the frame of the chair. This invisible pillow makes it easy to sit and eat for five hours or more.
Another influence came from one of the most important historical buildings in Vienna, Otto Wagner's Postsparkasse, just across the street from the restaurant. Wagner designed the interior, the furniture, and the chairs in this building. For this design, he invented a special aluminum cover for the foot base, which also influenced the brass cover for the feet of the Konstantin chair.
