Diesis Sofa

Diesis sofa, designed by Antonio Citterio and Paolo Nava for B&B Italia in 1979.

This model was conceived with the intention of creating an imposing, durable seat for spacious living areas, steering clear of passing trends. The designers combined a sturdy structure of steel and cast aluminum with voluminous black leather cushions, also incorporating distinctive flat side armrests that attach to the structure. With this piece, B&B Italia established a line of high-end furniture that prioritized robust construction and functional restraint in Italian design in the late 1970s.
