Osvaldo Borsani (1911 – 1985) was an Italian furniture designer and architect.


Osvaldo Borsani was born in Varedo Switzerland at the crossroads of craft and modern manufacturing. The son of a cabinetmaker, he trained as an architect in Milan in the 1930s, when the city was a centre of technological advancement and flourishing artistry, with the economic momentum to push both at speed. A creative pioneer, technical innovator and entrepreneur, he would come to revolutionise the world of contract furniture.

With his twin brother Fulgenzio, Borsani developed a new productive formula based on two tenets: ‘an original idea’ and ‘fulfilling a need’. Their vision took shape in 1953, when they founded Tecno, and started manufacturing Italian design on an industrial scale. The use of innovative technology gave Tecno furniture a distinct elegance that came to characterise the brand.

Borsani was best known for his 1954-55 p40 articulated chaise lounge and its matte, the 1955 D70 sofa version. The rubber armchair was a sophisticated ‘machine for sitting’ that could, it was claimed, assume 486 positions.
