When it comes to furniture design, the names of certain top European designers keep cropping up. Patricia Urquiola, Marcel Wanders, Jasper Morrison, Tom Dixon and Ron Arad are on everyone's lips. At last month's furniture fair in Milan, the list of products or installations with Spanish designer Urquiola's name on them numbered more than 35. Her geometric, structured and architectural-style chairs for companies such as B&B Italia, Driade and Moroso have become celebrated iconic designs around the world. She also designs bathroom fixtures for Axor, a division of Hansgrohe. Dixon first cemented his position as an established designer with a stackable, four-pronged lighting piece called Jack, which he has described as a 'sitting, stacking lighting thing'. It won him international acclaim and four years later in 1998, he was appointed head of design at Habitat and later became their consultant, prompting comparisons to founder Sir Terence Conran, who is famed for bringing contemporary design to the masses. Dixon is perhaps most recognised for his innovative lighting fixtures that have become much-copied. His Beat collection is a series of lights inspired by the sculptural simplicity of brass cooking pots and traditional water vessels on the Indian subcontinent. The New York Times called Wanders the 'Lady Gaga of the design world' - you name it, he's done it. He was one of the first Droog designers, a Dutch group, creating the Knotted chair made of macrame rope and epoxy resin, which is now part of the collection at New York's Museum of Modern Art. Wanders' own furnishing brand is called Moooi. He has designed lighting for Flos, tableware for Alessi and also for KLM's Business Class, an example of which was acquired by the Art Institute of Chicago for inclusion in their permanent collection. Morrison says he believes in democratising design. It is easy to understand why. The English product and furniture designer has designed everything from a tray-table to a tram system. At first glance, his work often looks simple and familiar, but closer inspection reveals his refinements and oft-use of new technology, such as his Air Chair, a relatively inexpensive moulded dining chair made from a single piece of plastic using Magis' new gas-injection technology. Israeli designer Arad became head of design at London's Royal College of Art after designing the Bookworm bookshelf that curves along the wall and is still produced by Kartell. Arad's work is one of the most sculptural - often crafted from steel and shaped into distinctive biomorphic shapes. He has also collaborated with Swarovski, creating chandeliers that can display text messages via light-emitting diodes.
