A patented sofa bed, D70 is the design manifesto for the wishes of Osvaldo Borsani: an item of furniture which is original, autonomous and elegant in form, but technical and industrial in production.

The mechanism allows the sofa to be opened out until it completely reverses - an iconic design solution which allows the backrest to open to any angle, even to make a bed. When the sofa was first presented as a “patented divan-bed” at the Exhibition of individual furniture items in the 10th Triennale Exhibition in 1954, it emblemised the fresh direction taken by the newly formed Tecno.

The D70 has two pivoting wings, a metal frame, polyurethane foam filling, and fabric or leather upholstery. The opening mechanism consists of a lever with a securing pin that engages with holes in a graduated plate. The mechanism is operated effortlessly by a practical knob and allows the backrest and seat to assume any angle and to fold down to form a bed.

Thanks to the way the soft parts adapt to the shape of the body and to its functionality, It become strikingly harmonious in form and extremely comfortable too, perfect for home, office and reception areas.
