What can I do if my chair wobbles when I am seated in it?

A wobble in a chair can be caused by a faulty control mechanism or chair base. To fix the wobble it is important to verify which of these is causing the wobble.

•    Control Mechanism: With the base of the chair set on the floor, pivot the seat from side to side by alternately putting pressure on the right, then the left the side of the seat. If the seat “wobbles” where the pneumatic cylinder and control mechanism join, the control mechanism is faulty and may need to be replaced.

•    Chair Base: Turn the chair upside down so the casters and base of the chair are not touching the floor. Pivot the base from side to side by alternately putting pressure on the right, then left the side of the 5-star base. If the base “wobbles” where the base and pneumatic cylinder join, the hub liner in the base has failed and the base may need to be replaced.

What does it mean if there is leaking oil or grease under my chair?

This issue could be caused by one of the following:

•    The seal on the cylinder has broken.

•    The chair's hub liner has come loose causing the cylinder to become misaligned.

•    If the chair is new, there has been too much grease applied to the hub liner in the base.
