normal force

A force exactly equal to the weight of your posterior against the chair. You know positively that the forces there must exactly cancel and add to zero, otherwise a net, non-zero force would be present, and your butt would accelerate.
If your feet are off of the floor, then the chair exerts your total weight against you.
When you sit in a chair, the action force is the downward force you exert on the chair due to your weight. The reaction force is the upward force exerted by the chair on you, supporting your weight and keeping you from falling to the ground.
normal force
It exerts normal force to you.
This is an example of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When you sit on a chair, your body exerts a downward force on the chair, and in response, the chair exerts an upward force on your body to support your weight and keep you from falling.
When you sit in a chair it exerts against you
A normal force.
because the floor exerts the same amount of force which means the net force is balanced causing it not to move
The pressure caused is created when the normal force of the chair (the chair pushing back against you, as opposed to breaking down) acts against your weight.
