Most seating for waiting areas begins with a frame: pieces of timber or steel joined together, then covered until the joints disappear. Sella begins with a mould. The back is a single shell of rigid Baydur® CSP polyurethane, formed in one operation, and the seat is a steel tube frame webbed with elastic polypropylene and natural latex belts. Nothing is hidden by the upholstery, because the shape already exists before the upholstery arrives – which is why the profile stays that thin along the arm and still holds its line after a few thousand visitors.
What sits on top of the shell is soft: contoured sheets of CFC-free foam, polyester wadding, bonded plush, and leather or fabric over all of it. The collection runs from the lounge armchair, 87 × 74 cm (34″ × 29″), to the two-seater at 147 cm (57″), and continues into swivel office versions – the executive chair, the conference chair and the tub – plus three low tables. Ludovica+Roberto Palomba signed it in 2024. La Mercanti quotes the whole set from one drawing and delivers it assembled.
