How long does the pneumatic cylinder last on an executive chair?

A quality pneumatic cylinder on a commercial executive chair should last 5–10 years of daily use. Signs of cylinder wear include: the seat slowly sinking during use (the most common symptom), difficulty raising or lowering the height, or a cylinder that bounces rather than adjusts smoothly. Replacement cylinders are available for most commercial chair models for $20–$50 and are easy to install (usually just a pop-off at the bottom of the chair mechanism). This is one of the most cost-effective repairs in office furniture. At FindOfficeFurniture.com, buying a quality commercial chair with a solid cylinder from the start is the best long-term value — call 888-719-4960 for options.
