Designed in late 1953, the DU30 is, without doubt, Gastone Rinaldi's most famous design. In fact, in 1954 it was the recipient of the Compasso d’Oro award, known as the Compasso d’Oro-Rinascente at the time, in what was the first year the prize was awarded. The jury that year included, among others, Gio Ponti, Marco Zanuso and Alberto Rosselli. The DU30 was immediately patented and appeared on the cover of the first edition of Stile Industria magazine in June 1954. The unitary nature of the seat and backrest results in a central cutting and stitching effect that brings to mind the contemporary works of Lucio Fontana.
