This bench in steel with a glazed finish is to be found in a niche in the foyer of the ENEL headquarters in Rome. This mono-block volume is made of only one stainless steel sheet, 5 mm thick, calendered by a 3D CNC program. It was properly bent, so there was no need for a substructure. At its extremes, the volume is capped by two surfaces welded to the seat, shaped exactly like the section of the bench.
