Designed in 1958 by architect Jørgen Rasmussen. It was originally designed for the company KEVI, but after the addition of the double-wheel caster, the chair quickly went on to become an international success.
In 1965, Jørgen invented the double-wheel caster. The KEVI casters are considered to be a reinvention of the wheel and were a true innovation and improvement to all existing furniture wheels. The double-wheel caster made KEVI more manoeuvrable with less wear on floor surfaces. The wheels became an instant success, and are now used on furniture across the world.
