Bar stool roots are tighten up with benches: examples of seating have been found in the Stone Age, where bench style seating was discovered in abundance. By using elevated seating, humans distinguished themselves from the animal kingdom. The evidences of today-known bar stools were found in ancient Chinese tombs as well as Egyptians. The Egyptians used both chairs and bar stools: the use of chairs was usually reserved for those with superior social status. This pattern continued, until the Renaissance, where the chair ceased to be a privilege only for the upper classes. Bar stools were used in the place of thrones in some African kingdoms such as the Golden Stool of Ashanti in Ghana.
Bar stools were originally made solely out of wood, however, the Industrial Revolution advanced the range of bar stools and increased the demand & popularity dramatically.
