Is it narrated from the Prophet, may God's prayers and peace be upon him, that he sat on a chair?

The Prophet, peace and blessings be upon him, was humble. He would sit and eat on the ground, accept the invitation of a slave, and chose to be a messenger-servant rather than a king-prophet. However, he would sometimes sit on a chair to teach people and make his words audible to them, which is a desirable action when needed. His companions also sat on chairs and beds.
