Emilio Nanni has practised as an architect and designer since 1984 and has taught furnishing design at the Faculty of Architecture of the University of Florence since 1990. He is also a painter whose work has been shown in public and private galleries. His collaboration with Billiani began with Doll in 2010, a wooden chair that has grown into one of the company's most extensive families, later joined by a steel bar stool. Spy (2015) makes the relationship between soft body and hard frame explicit: a thin seat leaves the cross bracing in view, and the rear legs rise behind a curved back. Marimba pairs wood with leather. Drum, Croissant, Babà and Babà Soft carry his vocabulary across chairs, stools, lounge seating and tables, giving Billiani one of its broadest bodies of work by a single designer.
