Because he had suffered a stroke, Howard MacNear (who played the barber) had trouble standing. A special stool was built to make it appear Floyd was standing when he was in fact half-sitting or leaning. Floyd was also often seen sitting in his barber chair or sitting on a bench outside his shop. (Howard’s stroke also left his left side paralyzed. Watch Floyd closely in later episodes, you’ll notice he will never move his left hand.) Now that’s accommodation so someone can continue to work!
