Thanks for the demo. I know that 1 inch pipe is a simple tool but is that something that you can buy from a hardware store like Home Depot or Lowe's? Thanks for any advice.

Although the video title is "Replace gas cylinder" the actual page title is: Office chair repair Steelcase gas cylinder. To me these are not one and the same. I am interested in how to repair a chair (cylinder) first without needing to replace the cylinder. If then this doesn't work out then and only then would I need this video.
