At the start of his work, he focused on light fixtures, co-operating with Lucis. Besides lighting, René Šulc has worked with furniture – his Chaise-longue sofa, for instance, was nominated for the project Czech 100 – A Hundred Icons of Czech Design. In 2006, René Šulc set up his own studio Inveno which follows up and develops his experience with industrial design. The studio is mostly devoted to the design of light fixtures, furniture, product design but also to the design of medical instruments. René Šulc’s work is inspired by everything around him - events, perceptions, natural shapes and even growth.
For TON, he designed the Era chair, the Symposio bench and the Santiago series.
