What part of the human body controls posture and balance when sitting?

If sitting still on a chair which part of the body is responsible for controlling posture and balance? I know the main part is the cerebellum but how does it work?

    Posture and balance (aka proprioception) are coordinated by input from the inner ear,eyes and joints of the body. Conscious proprioception is relayed mostly by the dorsal column and in part by the spinocervical tract. Finally, the organ of perception for position sense is the sensory cortex of the brain. So data from your joints, eyes and ears all feed into your sensory cortex and then the brain sends signals via the spinal cord to the various muscles to tell them how to contract so that you maintain balance and posture.
