Frequently Asked Questions
How do I know whether to replace the cylinder or the base?
If the chair sinks (won’t hold height) or the lift releases, the gas cylinder is usually the problem. If the chair wobbles, tilts, or a leg is cracked or bent, the base is the likely culprit. Measure and inspect both: a leaking or stuck piston points to the cylinder; visible cracks, bent spokes, or broken caster sockets point to the base.
Are these repairs something I can do at home?
Yes — many cylinder and caster replacements are straightforward with basic tools. A rubber mallet, adjustable wrench, and penetrating oil are often enough. For stuck cylinders, a removal tool (included with some kits) or a simple wedging method usually does the trick. If you’re uncomfortable or the chair has complex mechanisms, a local repair shop can help.
Will replacing parts really extend the chair’s life?
Replacing the failed component (cylinder, casters, or base) can add years to a chair if the frame, upholstery, and mechanisms are still in good shape. Prioritize structural parts first: a solid base and reliable cylinder restore safety and daily function; new casters improve mobility and protect floors. Regular maintenance — tighten bolts, clean mechanisms, and swap worn casters — also prevents early failures.
