How do I replace the gas cylinder on an office chair?

Gas cylinder replacement is a standard maintenance item at OfficeFurniture2go.com. We maintain a cylinder inventory for most commercial chair models we sell. The replacement is a 10-minute DIY repair requiring a pipe wrench and a rubber mallet. We provide cylinder dimensions (OD, stroke length, and thread type) for every chair we sell, making specification of a replacement cylinder straightforward. Replacement is far more economical than full chair replacement when the structure and foam are still serviceable. Call 1-800-460-0858 for cylinder sourcing assistance.
