This 1934 design is an expression of the #8220;De Stijl#8221; movement. Its deceptively simple Z-form arose from Rietveld´s desire to create a chair from a single piece of material. When this proved impossible in various materials, he resorted to the unorthodox method of bolting together planks of hardwood to give the impression of a continuous form. This was far from traditional furniture construction. From Cassina, “I Maestri” Collection. Cassina is the exclusive licensed and authorized manufacturer of Gerrit T. Rietveld designs world-wide.
