Flos Toio LED Red by Achilles And Piergiacomo Castiglioni Floor Lamp

The idea of the readymade didn’t just upend the art world, it also provoked a wave of invention in design. This provocative spirit is alive and well in the Toio floor lamp, which sees an integration of automotive parts as well as everyday recreational gear.

Along with their eldest brother, Livio, Pier Giacomo (1913–68) and Achille (1918–2002) Castiglioni were born in Milan and for a time, the three worked together in their own firm as architects and designers. While Livio departed the practice in 1952, Pier Giacomo and Achille would continue to collaborate on a wealth of projects in the ensuing years. The pair shared an experimental nature and injected personality and wit into the wide range of their celebrated mid-century modern designs, such as the Arco lamp, the Snoopy lamp and lots more.

Inspired by Marcel Duchamp, the brothers often used found objects in their designs, notably in the Mezzadro Tractor stool, the Super Sella stool and the Toio floor lamp. Produced by FLOS in 1962, the Toio (“toy”) incorporates a car headlamp and elements of a fishing pole. The height of the headlamp, which always faces up to provide indirect light, is adjustable, while fishing-rod rings at intervals along the stem help guide the electrical cord. At the base, a mechanism similar to the cleats on a boat keeps the cord neatly coiled and tucked away from view. These inventive utilitarian touches earned the fixture a coveted spot in MoMA’s permanent collection. Unusual and delightful in equal amounts, the Toio floor lamp is still manufactured by FLOS and reminds us that humor is a potent element of design.

Milanese industrial designer-architects Achille and Pier Giacomo Castiglioni (1918–2002; 1913-68) created some of the most iconic furniture designs in the world, particularly those that originated in the realm of mid-century modern lighting. 

In the late 1930s, after graduating from the acclaimed Polytechnic University of Milan, Pier Giacomo opened a design studio with his brother Livio and likeminded architect Luigi Caccia Dominioni. Achille, also a graduate of Milan Polytechnic, joined the group after completing his studies in 1944. The era’s architects were encountering difficulty in their attempts to secure building commissions, so the group focused on designing practical everyday objects such as the Model 547, a tabletop radio for Phonola that was encased in Bakelite. 

The Castiglioni brothers produced wildly popular and innovative designs throughout the 20th century. While Livio departed the practice in 1952 to pursue lighting design and sound technology on his own, Pier Giacomo and Achille would continue to collaborate on a wealth of projects in the ensuing years. 

Vintage furniture collectors may be familiar with Livio and Italian designer Gianfranco Frattini’s serpent-like Boalum lamp, while Achille’s Taraxacum hanging lamp — created for FLOS with sprayed plastic polymers originally intended for military use — as well as the Arco, Snoopy and Toio lamps, which were the result of the collaboration between Pier Giacomo and Achille, are milestones in modernist lighting design. 

Also for FLOS, Pier Giacomo and Achille created a series of metal frames that, wrapped in the polymer, became floor lamps (Gatto) or pendant lights (Viscontea and Taraxacum), all released in 1960. The Gatto floor lamp takes its name from the Italian word for “cat” and the inspiration for its aesthetic from lighting that George Nelson developed for legendary American furniture manufacturer Howard Miller during the 1940s. Around the same time, the designer Tobia Scarpa (son of the famed Italian architect Carlo Scarpa and one-half of the widely revered postmodern husband-and-wife design duo Afra and Tobia Scarpa) created a floor lamp called Fantasma (1961) using the polymers technique. FLOS continues to make the Castiglionis’ innovative pieces today.

In addition to their provocative lighting works, Pier Giacomo and Achille also created stereo systems, decorative objects, seating, tables and other items for the likes of Brionvega, Alessi, Zanotta, Kartell and more.
