“The details are not the details, they make the design.” That’s how Charles Eames summed up his design philosophy. He most certainly paid attention to detail in creating the Eames aluminum chair, which turns 50 this year. You can view the classic creation at the Museum of Modern Art in New York or at the Centre Pompidou in Paris, but ifyou want to sit on one, be prepared to fork over a load of cash, or settle for a reproduction. Herman Miller Group offers the real deal. The Herman Miller Eames aluminum group side chair runs $880 (pictured), while the Group executive chair costs $1,600. If a knock-off will do, try Fast Furnishings.com, where the Eames lookalike chair is $180 with free shipping. This 100 percent leather Eames-style office chair is $250 on sale at All World Furniture and features a chrome plated steel ram with rolling base. CB2’s Surf office chair is available in red or white and includes executive features like 360-degree swivel and gas lifts for height adjustment ($200). Though no exact replicas are available at Ikea, the ultra-hip bargain store sells a variety of modern office chairs, including the Patrik visitor’s chair ($150) and the Rutger/Jules swivel chair ($60). You’ll be happy to take a seat.     Ikea, the ultra-hip bargain store sells a variety of modern office chairs  including the Patrik visitor’s chair ($150) and the Rutger/Jules swivel chair ($60).
