Compressed air is the mechanism that makes the chair work. Compressed air (gas) is the way all pneumatics work, even power tools, like nail guns and staple guns. Compressed gases (air is a gas) are used to assist mechanical motion or processes. Air in the atmosphere is sometimes captured for this purpose especially in industrial (factory) applications. Pneumatic chairs, on the other hand, use compressed air to move the seat up and down. Pneumatic Chair Components The base of the chair, usually a three, four or five star metal base, is used to insert a gas cylinder into. The gas cylinder, also called a gas lift or spring, is then shrouded with a telescoping cover to create a column. Placed on top of this column is the seat.
