How long do conference chair gas cylinders last?

Commercial conference chair gas cylinders (pneumatic lifts) typically last 5–10 years under normal use, with premium cylinders lasting 15+ years. Cylinder failure manifests as the chair slowly sinking after the height is set. Replacement cylinders are available for most commercial chair models at $20–$60.
