Irma Design Chairs by Achille Castiglioni for Zanotta, 1970s, Set of 4

Milanese designer and architect Achille Castiglioni sought to inject personality into all of his work, and found deep inspiration in everyday objects. A legend of Italian mid-century modernism, he created iconic, universally loved table lamps, chairs and other lighting and furniture with his likeminded brothers during the postwar years. 

There was the Snoopy lamp, which brings to mind the unmistakable Peanuts character, while the shape of a common street lamp inspired the design behind the Arco floor lamp. Elsewhere, the Toio floor lamp — a provocative fixture in any living room — was made with automotive parts as well as run-of-the-mill recreational gear. 

Castiglioni studied the classics at Liceo Classico Giuseppe Parini, art at the Accademia di Belle Arti di Brera and finally architecture and design at the Polytechnic University of Milan. After graduating in 1944, Castiglioni began working with his brothers Pier Giacomo and Livio at the studio they cofounded with classmate Luigi Caccia Dominioni.

Livio left to pursue lighting design and sound technology, leaving Achille and Pier Giacomo to continue to collaborate on various projects. One such design was the iconic Taraxacum hanging lamp for FLOS which featured a resin “cocoon” created with sprayed plastic polymers that protects its steel core and allows for the diffusion of light.

Castiglioni won Italy’s highest award for industrial design — the Compasso d’Oro — seven times, and the Museum of Modern Art was home to his first individual retrospective in the United States. Castiglioni later taught at the Polytechnic University of Turin and at Polytechnic in Milan.

Castiglioni’s designs remain timeless. Some of them can be found in Tokyo’s Living Design Center Ozone, the Triennale di Milano and the Hangaram Art Museum at the Seoul Arts Center.

Entrepreneur Aurelio Zanotta founded Zanotta in 1954 in Nova Milanese, Italy. Originally called Zanotta Poltrona, it specialized in traditional furniture. By the early 1960s, however, Zanotta had established a reputation for edgy mid-century modern design. Today’s vintage furniture collectors know the brand well for its innovative and wholly sculptural chairs, coffee tables and more.

One of Zanotta’s earliest successes was the Mezzadro stool — better known as the Tractor stool — designed by Pier Giacomo Castiglioni and his brother Achille in the late 1950s. In 1965, Zanotta was among the first furniture companies to work with expanded polyurethane foam and frameless construction, such as for the Throw-Away sofas and armchairs designed by Willie Landels. Another popular design was the Blow chair — designed by Jonathan De Pas, Donato D’Urbino, Paolo Lomazzi and Carla Scolari — viewed by many as a physical expression of late '60s carefree culture.

In 1969, amid the provocative movement we now call Italian Radical Design, Zanotta’s Sacco chair garnered major attention. The boundary-pushing beanbag chair was the brainchild of designers Piero Gatti, Cesare Paolini and Franco Teodoro who presented it to Aurelio Zanotta as a transparent vinyl sack loosely filled with small polystyrene balls. He suggested its signature brightly colored leather.

The Sacco chair won the 1970 ADI Design Museum’s Compasso d’Oro award. In 1972, the Museum of Modern Art in New York included it in the landmark exhibition “Italy: The New Domestic Landscape” curated by designer Emilio Ambasz. In 2020, it received a Compasso d’Oro ADI Lifetime Achievement Award for 50 years of enduring popularity. It is now in museum collections around the world including the Triennale Design Museum of Milan, the Musée des Arts Décoratifs in Paris, and London’s Victoria Albert Museum.

After Aurelio Zanotta died in 1991, the company remained in his family and has been run by his three children since 2002. Zanotta continues to set the bar high for furniture design with trend-setting pieces.
