The Dutch architect and furniture designer stated this wasn’t a chair but “a little partition in space that leaves the space untouched. It is not a chair but a structural joke. I always called it the little zig-zag” [1].

Rietveld produced countless sketches to try to create a chair that could be mechanically produced by folding a single piece of material. This proved more difficult than expected and eventually resolved this issue by using four pinewood cupboard shelves produced by kitchen manufacturer Bruynzeel connected with dovetail joints and brass screws.

This example has been verified by Archives team at Cassina as an 1973-75 version produced by them in cherry wood. It bears the manufacturers mark and No. 2 stamp on it’s base.
