The idea of forming a seat from a single sheet, conveniently cut and folded, struck several architects in the last century. I recall some attempts by Rietveld, Breuer, and especially a prototype that Alvar Aalto developed in the 1930s, taking advantage of the new technology of preformed plywood.

Demonstrating my deep admiration for the Finnish master, I myself created some pieces from methacrylate sheets in 1970, at the beginning of my activeness as a designer. Thirty years later, I studied the “Sinuosa” by cutting and folding sheets of paper and plastic.

During the development of the project, I realized the convenience of giving up on folding a sheet and opting for an injection process, which offers greater economy and much more freedom in the geometry of the piece. However, I approached this freedom with great caution, because as I found that the further I strayed from the shape developed in the initial prototypes, the more clarity and coherence it lost.

Orthodox might argue that the form does not reveal the production process, and I can only answer that what it expresses is the process of its design.
