The upholstsery lays like a dress on the wooden frame. The two pieces (for the seating and backrest element) are produced in an industrial processing. The upholstery material than lies between the textile sides is welded in a high frequency technique. The third dimension only emerges through folding onto the wooden frame of the chair. The pieces of fabric are fixed with a system of press-studs. Therefore it is easy to exchange them. With the different colours the expression changes remarkably.
