360 adjustment ring - "dead" spot?


Inside the adjustment system, the bolt that presses the button to release the cylinder isn't out far enough.

This can be adjusted by popping off top and adjusting the bolt just a bit. Not too much because it will then trigger the adjustment when one sits on it.

The fit of the cylinder to the rest of the chair is a pressure fit. To remove the cylinder from the seat:

• Lower seat all the way to its lowest height.


• Flip chair/stool upside down.


• Pick the chair/stool up by the cylinder and tap/hit the seat down using a rubber mallet. Be careful not to damage the seat or adjustment mechanism. It should fall away.

Inside the hole where the cylinder was inserted, there is a 10mm bolt.

• Turn the bolt counterclockwise with a 10mm socket (about a half turn at first) so that it comes further out of the seat.


• Replace the seat.
