The Chair One by Konstantin Grcic, is a beautiful structure inspired chair that is both simple and complex. Its simplicity is seen in its defined lines and its complexity is highlighted in the engineering ingenuity that is behind it. It was inspired by a football, which is created by assembling a number of flat surfaces @ different angles, hence creating a three dimensional form. This structural logic was reached after many sketches, cardboard models, and  prototypes. The final chair design was composed of  treated aluminum and a polyester powder coating.
