According to Newton's third law of motion, every action has an equal and opposite reaction. Therefore, the force exerted by the chair on me will be equal and opposite to the force I exert on the chair. In this case, since the chair doesn't move and I push lightly, it means that the force I exert on the chair is equal to the force the chair exerts on me.
