Quattrifolio was born in 1964, while the wave of Italian design was in full development during those years. The intention to produce well-made objects, as well as a sophisticated design, has enabled us to contribute to the growth not only of the company but also of the entire design scene in Italy. Over the years the company maintained the original concepts of the founding members. At the same time, the current management team is popular and has been working in the lighting and design sector for decades and giving life to Quattrifolio 1964 s.r.l.

The specific experience of the working group forms the basis for production in terms of quality, technology and design. The innovations of the productive activity in each sector, indispensable elements for dialogue on an international market. Together with them, it is our intention to give our discussion partners everything that is best in service, technical assistance and service, constantly talking to them, both with men and with current technologies.
