what events led up to the invention or the innovation of the chairwho is the inventor or innovator of the chairif you answer, get some sources. THANKS
Chairs have been around longer than ANYONE can ever remember. The Ancient Egyptians had chairs. We have no idea who invented the chair. And chairs haven't developed that much more since the dawn of time. They all have legs, even way back when they were very decorative, some had backs, some didn't, even in Ancient Egypt.
Not only did they have chairs since well before recorded time, they also had folding chairs since well before the start of the Roman empire.
