Angelo Mangiarotti Set of Four Dining Chairs, “Programma S11” Sorgente del Mobile, Italy, circa 1960 Walnut, Skai upholstery This refined group of four dining chairs from Angelo Mangiarotti’s Programma S11 captures the designer’s disciplined approach to structure and proportion during the formative years of Italian post-war design. Produced by Sorgente del Mobile, the model is distinguished by its attenuated vertical back supports, gently splayed legs, and a calibrated dialogue between mass and void. The walnut frames are executed with notable precision, their slender silhouettes revealing Mangiarotti’s architectural sensibility — a pursuit of purity where load-bearing elements are expressed with quiet clarity. The seats and back pads, upholstered in cognac-coloured Skai, introduce a warm counterpoint to the walnut’s deep tonality, softening the geometric rigor while preserving the ensemble’s overall restraint. The visual rhythm of the four chairs — upright, poised, and elegantly minimal — underscores Mangiarotti’s ability to endow functional furniture with a sculptural presence. Models from the S11 programme remain comparatively scarce, and sets surviving in this cohesive state are particularly sought after. A compelling early expression of Mangiarotti’s design language, merging structural exactitude with an understated, architectural elegance.
