I think we can think of the chair as definitely tying into Veblen’s theory of the leisure class. The following is excerpted from something I wrote some time ago, but I think is relevant to this discussion:
The idea of the chair or the throne has been equated with status from the Egyptian pharaohs to the European kings to today’s chairmen of the board. Advanced social status means you get to be the one sitting while others scurry around. … The ruler sat on his throne while the workers toiled in his fields. … The gods of ancient myth sat the most upright and in the highest thrones.
Being able to sit – and sit in a comfy chair (I inherited an aeron, which is apparently a big deal) is a show of how much leisure we can afford. At some points in history rulers are carried around in their chairs. Now we have cars with chauffeurs – servants that are great displays of wealth. To sit while others must stand is divine… - Nick
