The rubber membrane is placed onto the stool. Most of the air in between the rubber and the stool is evacuated, creating a vacuum seal. Since the pressure between the rubber membrane and the stool is close to a complete vacuum, the atmospheric pressure acting on the outside faces of the stool and rubber is large enough to pick up the stool with just the rubber and hook system.
