Gehry’s experimentation with cardboard furniture grew from his extensive use of it in architectural models. To show the strength of the laminated cardboard material, he famously photographed a Volkswagen Beetle supported on all four wheels with cardboard side chairs (see photo below – taken for the 1972 Easy Edges Brochure- shown here from the Frank O. Gehry catalog). He used a particular type of multi-layer corrugated cardboard, and stipulated its use in the production versions by Vitra. Over time cardboard technology has changed so current production uses a different cardboard, considered even stronger yet slightly lighter in color. When new, cardboard chairs exhibit a crisp, scratchy surface, due to the stiff paper edges. Over time, and with prolonged use, the paper wears to a soft sueded patina, which is both beautiful and comfortable.
