Barber chairs are often raised and lowered using gas or hydraulic struts. These struts work by using strong springs or pressurized gas. Some of these devices can be recharged, or have replaceable seals, but others are disposable items that are replaced as a unit.
There are two chambers an upper and a lower. If the chair is all the way down the fluid is in the upper chamber. When the barber selects the chair to go up the fluid from the top is forced through a metering valve to the lower chamber. As the lower chamber fills the chair moves up into the space that is vacated in the upper chamber.
