What gas cylinder size does an executive chair use?

Standard executive chairs use a Class 3 or Class 4 gas cylinder. Class 3 cylinders provide approximately 4" of travel; Class 4 cylinders provide 5"–6" of travel and are found on heavy-duty or extended-range models. Cylinder diameter is typically 2" (50mm) for standard chairs. When replacing a cylinder, you need to match the class rating, diameter, and stem dimensions.
