Swivel chairs have been around since 1800 when Thomas Jefferson invented one to allow the poorly treated office workers of the time a bit more comfort whilst multitasking.
Up until then the office chair was just a hard wooden affair, not dissimilar to a dining chair. The swivel feature allowed the worker to easily access different areas of the desk, in order to undertake different tasks.
These chairs, however, still looked like dining or captains chairs, just mounted on an early version of a 5 star base.
Soon after the arrival of swivel chairs, some bright spark fitted furniture castors to the bottom of these bases, and the office swivel chair was born.
