Gio Ponti designed the first Montecatini building at Largo Donegani in Milan in 1935. He designed everything, architecture and furnishings: desks, chairs, lamps and wardrobes.
With the approval of the Ponti heirs, in 2014 Molteni is reworking the Montecatini chair, with a seat and seatback covered in hide leather, following the all-aluminium version.
