Next to his "Red-Blue" chair, the "Zig Zag" chair is Rietveld's best known furniture design. The idea of making a chair out of a single, continuous surface had preoccupied Rietveld since 1927. He wanted to create a functional form that would not displace space, that would be perceived as a continuum of space. Initially, he tried to produce the chair from one single piece, experimenting with various materials. His solution was four apparently freestanding surfaces with hidden bolted wooden panels, though this required some ingenious construction. Rietveld continued to add further stabilizing elements through the years.
