Judd also worked with furniture, design, and architecture. He was careful to distinguish his design practice from his artwork, writing in 1993: The configuration and the scale of art cannot be transposed into furniture and architecture. The intent of art is different from that of the latter, which must be functional. If a chair or a building is not functional, if it appears to be only art, it is ridiculous. The art of a chair is not its resemblance to art, but is partly its reasonableness, usefulness and scale as a chair... A work of art exists as itself; a chair exists as a chair itself.
