Original 'd70' daybed sofa, designed by osvaldo borsani and manufactured by tecno, italy, in 1954. This mid-century classic serves as both a sculptural sofa and a fully adjustable daybed. Its clever mechanism — operated by brass knobs and a stepped metal plate — allows the backrest and seat to move independently into 18 different positions. With a simple turn, the piece transforms into a comfortable daybed. The sofa features a black lacquered tubular steel frame and is upholstered in anthracite grey fabric. A matching loose cushion is included. The brass fittings and exposed hinges highlight the technical refinement and italian modernist aesthetic of the 1950s. The fabric is in good vintage condition with minor fading from age and use; the foam remains firm and supportive. A distinctive piece that beautifully balances sophisticated design with practical versatility. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
