First launched in 1958, architect Jørgen Rasmussen's revolutionary swivel chair sparked this 50th Anniversary Edition with its seat and backrest fully upholstered in welted full-grain leather. Though his Kevi gets a luxurious upgrade, it's still a masterpiece of function and hews to Jørgen's original credo that comfortable, supportive seating enhances the ability to get work done. Available in 4 different heights, each equipped with the characteristic aluminum base complete with automatic height adjustment and the double-wheel castor introduced by Jørgen in 1965—that is still seen today on everything from office chairs to rolling suitcases.
