Each handmade Vitra miniature is a classic in the history of furniture design reduced in size at a scale of 1:6. True to the original pieces in structure and materials, the miniatures are precision-crafted, making them a thoughtful gift for a furniture lover or design professional. On the occasion of the XIth Milan Triennial in 1957, Achille and Pier Giacomo Castiglioni presented their first prototype for the Mezzadro. The stool went on show in its current form that same year in an interior setting displayed at the Colori e forme nella casa dâ€™oggi exhibition in the Villa Olmo in Como. The designers used a common tractor seat for the springy metal seat, fastening it with a wing nut to the spring-based arched steel strip utilized in tractors to absorb the shock of uneven ground. They enhanced the stability of the cantilever structure by a wooden cross-strut that resembled the rungs of a wooden ladder. Each of these parts clearly embodies its task as a part of a functional whole. And what strikes the eye is the recourse to an artistic method exemplified by Marcel Duchamp's found objects or Pablo Picasso's assemblages. The Castiglionis considered a design successful only once they had managed to eliminate all the unnecessary components and an optimal formal expression had been found for this concentration on the essential. Each miniature comes handsomely packaged in a wood box with an informational booklet. Red Achille Castiglioni: Vitra Miniatures Collection: Castiglioni Mezzadro.
