Oslo is characterized by the contrast of its side profile, where the backrest’s incline meets the rectilinear profile of the armrests. To enhance ergonomics, the design features a gentle indentation where the back rests, facilitating head support. The upholstery is fully removable. The seat cushion is also removable and available in leather.
The frame is made of wood covered with foam and fiber. Suspension is provided by interwoven elastic webbing of varying tensions.
The seat, backrest, and armrests are made of different densities of polyurethane foam, with a fiber-padded surface. The swivel base is metal, available in flat or cross-shaped metals with a manganese-finish polyester powder coating.
