What is the gas cylinder in a swivel conference chair and can it be replaced?

The gas cylinder is the adjustable-height mechanism inside the chair base — it uses compressed nitrogen gas and a valve triggered by the lever under the seat to raise and lower the chair. When the cylinder fails (the chair slowly sinks when you sit), replacement cylinders are available and typically take 5–10 minutes to swap.
