Achille and Pier Giacomo Castiglioni
Achille and Pier Giacomo Castiglioni, drawing on the “ready-made” school of thought, worked from the viewpoint that design must restructure an object's function, form, and production process. After 1960, Achille and Pier Giacomo mainly focused on industrial design and shop displays. Some of their most well-known collaborations are best characterized by ironic humor, such as in the case of the Mezzadro (1955) stool formed of a metal tractor seat, or the Sella (1957), a pivoting stool featuring a leather bicycle seat. Other highly recognizable works include the Arco and Toio lamps (both 1962). Their designs link technological innovation, occasionally defamiliarization, and Minimalism, in objects that are as aesthetically pleasing as they are functional.
