Product Highlights
Reach New Heights
Whether you're working at a standing desk, a drafting table, or a high counter, standard chairs just don't reach. Our Stool Cylinder bridges the gap, giving you a massive adjustment range so you can work comfortably at any elevation.
Easy Upgrade
Instead of buying a new stool, easily convert your existing Aeron chair into a tall stool. Simply use the "twist and knock" method to remove your old cylinder and drop the new one in.
Perfect Compatibility
This cylinder is tailored to fit the Herman Miller Aeron base and seat mechanism. It uses a standard 2-inch column diameter, making it compatible with most other office chairs as well.
Smooth Operation
The durable construction ensures smooth and safe chair height adjustment. Be sure the mechanism pin inside the tilt cover is horizontally level to ensure proper engagement for the best performance.

Frequently Asked Questions
Will this fit my Aeron Chair?
Yes, this cylinder is tailored to fit the Herman Miller Aeron base and seat mechanism. It uses a standard 2-inch column diameter, making it compatible with most other office chairs as well.
What if the height adjustment isn't working?
As shown in the video, you may need to adjust the mechanism. Remove the tilt cover and check the black pin (or set screw) that presses the cylinder button. Tighten or loosen it until it sits horizontally level; this ensures it engages the button properly to lift or lower the seat.
How do I remove the old cylinder?
We recommend the "twist and knock" method. Remove the seat pan (optional but easier), then use a pipe wrench to twist the cylinder loose from the mechanism. Flip the base over and use a hammer to knock the cylinder out of the spider base.
Do I need a footring?
While not strictly required for the cylinder to function, we highly recommend adding a footring if you plan to use the chair at full height. It provides essential support for your legs, preventing fatigue.
