From the article: LONDON: If there's one quality that defines contemporary furniture design, it's flexibility. Whether they call themselves new expressionists, techno-romanticists, neo-rationalists or whateverists, designers are striving to create furniture that people can adapt to suit their needs, and adapt again as their needs change.

One chair, launched in London last week, pulls it off. It comes as a kit of interchangeable parts that can be assembled into a chair with a high back or a low one, to swivel or not, with arms or without, and to be joined together with other chairs to create as long - or as short - a sofa as you wish. But this chair, the 620 Chair Program, isn't really new. It was designed in 1962 by the German designer Dieter Rams, and is being reissued in the United States and Britain by its manufacturer, Vitsoe, and Moss, the New York design store.
