This replacement lift cylinder is the standard size that fits most all office chairs. 2 inches at the base and 1 inch at the seat plate. It is 10.5 inches when retracted and 15.5 inches at full length. That is 5 inches of lift, which more than enough for most situations. Replacing it is easy peasy and if you have trouble, feel free to call us and we will walk you through it (our number is included with the instructions).
