Rob Fissmer works at the only Vitsoe (pronounced Vit-soo) showroom in the US, located on Bond Street in New York’s SoHo shopping district. Essentially, any American purchase order goes through him. Dieter Rams designed Vitsoe’s 606 Universal Shelving System in 1960, and it’s been in continuous production ever since. Rob talked to us about how a product survives 50 years, evolving and adapting while remaining fundamentally unchanged.
