What is the correct sitting posture while eating?

It has been established that the Messenger of Allah, peace and blessings be upon him, ate while kneeling, while squatting, and while sitting on his haunches, out of humility. He ate kneeling on his knees, and he said: "Indeed, Allah has made me a noble servant and has not made me an obstinate tyrant." He also ate while squatting, which is when one places their buttocks on the ground and raises their shins, or while sitting on his haunches, not firmly seated. Thus, any sitting posture that indicates humility is valid for eating.
