More than 60 years after the original idea, the iconic armchair Round (D.154.5) was reborn thanks to the Heritage Collection reissue project by Molteni&C, in collaboration with the Gio Ponti Archives. As with all the projects in the collection, the careful study of drawings, photos and period materials has made it possible to faithfully reproduce the armchair in every detail, bringing a forgotten master-piece back to life. Designed in 1954, full production began in 1956-1957 and it was officially presented at the 11th Milan Triennale in 1957 (Feal Pavilion), along with other innovative Ponti furnishings, in a limited number of examples which are now highly sought after by collectors. Gio Ponti was very fond of this chair and has often used it to furnish his architectural projects, such as Italian Cultural Institut Stockholm (1957); the Parco dei Principi Hotel in Sorrento (1960); the villas Planchart (1955) and Arreaza/Diamantina(1956), the latter now demolished, both in Caracas; the Alitalia offices in Manhattan(1958); the Alitalia passenger terminal (1960), in the Centrale station area in Milan, where a modified version was used, with the curved plywood replacing by a chromed metal tube, for long lines of waiting seats and two or three seater sofas designed ad hoc. Proposed with Vipla upholstery, strictly two-tone, white and blue or white and yellow, it is also produced in fabric, for the Villa Planchart study, and for the Parco dei Principi Hotel in Sorrento, in dark blue.
