The gas cylinder or gas lift is a critical component of your office chair. When the gas cylinder has lost its lifting power and does not swivel as smoothly as it used to, it is time to replace it.  A new gas cylinder will make your office chair as good as new. All gas cylinders bed in over time and can be quite difficult to remove. The innovative new ERGOtool from Ergohuman Australia is a new device that makes light work of removing a Gas Cylinder from any Office Chair. Just clamp the tool onto the shaft of your old gas cylinder and use the screws to extract it from the seat base of the Chair. It can be purchased on its own and it is included with all replacement Ergohuman Gas Cylinders.

No more messing around with duct tape and a pipe wrench.  Get the guide to removing your gas cylinder here. Shipping is free when purchased on its own.
