Everything is in great shape and functions as expected with the exception of the piston in the gas cylinder as it only rises with the chair on its side and the piston can also detach when the chair is lifted. It also appears to have the incorrect retaining clip on the bottom. There are several options available online for a replacement gas cylinder kit from OEM to aftermaket. Please see pics for closer detail as they should be considered part of the condition description and feel free to message us with any questions and/or requests for additional pics. Thank you for looking!!
