It is tough to tell who invented the chair because the early designs of working chairs are found in Egyptian civilization, which artisans used while working. The modern-day classic working chairs were invented two centuries ago when Charles Darwin designed his work chair by attaching wheels to the wooden legs so he could maneuver around easily. The American inventor Thomas E. Warren designed the Centripetal Spring Armchair in 1849. His design had a swivel mechanism and castors, which allowed office workers to sit and work for hours comfortably.
