Onda means “wave,” and this one’s best caught in your living room. Dreamed up in 1985 by De Pas, D’Urbino, and Lomazzi for Zanotta, it captures the bold spirit of Italian postmodern design without ever feeling overworked. A tubular steel frame props up its sweeping seat, navy upholstery keeps it cool, and that arched back makes sure it looks good from every angle. Made in Italy, of course — where casual seating still knows how to steal the spotlight.
