Designed by VALENTINA VOLPE - Powered by DESALL Valentina Volpe was born in Pisa in 1984, in 2007 she graduated in Furniture and Interior Architecture and in 2013 she graduated in U.E.

In addition to architectural research, he combines artistic research with his personal path in the field of photography and ceramic sculpture. Polygon was born in 2019: a radiator with a decisive and contemporary design. A plastic movement connotes the object of a double aesthetic and functional value: the radiator is enriched with a new functionality, also becoming a lighting body; the fold of the external surface in fact houses a LED luminous blade that enhances its profile and creates a storage space in the horizontal version
