What is pneumatic seat height adjustment on an ergonomic chair?

Pneumatic seat height adjustment uses a compressed gas cylinder to smoothly raise and lower the seat with minimal effort. Standard cylinders provide 4"–5" of height travel range. Pneumatic cylinders are the most common single component to fail after 5–10 years of use but are easily replaced, often for much less than the cost of a new chair. Cylinders are available in standard, tall, and short heights to extend the chair's height range.
