All of these chairs are identical in size and shape, but there's one important difference between them. Each chair is made from a different material. One's marble. Another's redwood. The others are in concrete, acrylic, wickerwork, attaché-case metal, polyurethane foam, felt and even hay.

The result is intriguing. Each material transforms the appearance of the chair, creating what seems like an optical illusion. The transparent acrylic chair seems to melt away to nothingness. The marble one looks chunkier, and the redwood chair chunkier still. That's exactly what their designer, Naoto Fukasawa, wanted to happen when he hit upon the idea of creating a series of chairs to illustrate the impact of a single design decision - the choice of material.

Fukasawa's nine chairs are part of Vitra Editions which are exhibited at Vitra's production complex in Weil-am-Rhein on the border of Germany and Switzerland.
