Hannes & Fritz is a design collaboration between German-Swiss design duo Johannes Breuer and Fritz Gräber. They met at ECAL in Lausanne, Switzerland. and what started as a friendship developed into a spontaneous design collaboration with the construction of a bench at a dinner party. The result was a very successful partnership and since then they have created designs for a number of international furniture companies, often starting their projects by exploring existing archetypal forms, before defining them in a more contemporary context. For HAY their most successful design is the Weekday Collection which includes the  Weekday Table and Weekday Bench.
