The seat structure is in tubular metal with woven elastic belts. The backrests and armrests are made from birch plywood. The external padding of the backrests and sides is in polyurethane foam and polyester wadding while the inner layer is in polyester wadding, covered with soft fabric quilting with “X” stitching produced by hand using contrasting thread. The seat cushion is in goose down and polyester wadding with stabilising polyurethane foam insert. To enrich the backrest, every GranTorino HB armchair has a precise number of loose goose down cushions. The upholstery combines leather or saddle-leather with fabric: Saddle, Saddle Extra or Pelle Frau® leather for the vertical panels of the backrest and sides and removable fabric for the base, cushions and quilting. The saddle-leather version is enriched with relief stitching and the hide with clean cut edge is finished by hand. The complementary side table has a painted steel base, coloured titanium or gunmetal grey, and a top in Canaletto Walnut or covered in Pelle Frau® leather or saddle-leather.
