Crandall Office Furniture’s Herman Miller Ergon 3 aftermarket stool gas cylinders have been constructed to meet original OEM chair specifications and are built to last.
A office chair gas cylinder is the height adjustment mechanism on the chair. The typical life span of a office chair gas cylinder is 4-7 years, depending on use and abuse. If failed, your chair will be left with limited or no height adjustment, however you can quickly and easily replace your broken Herman Miller Ergon 3 stool gas cylinder today.
Our Herman Miller Ergon 3 gas cylinders are made to fit all Herman Miller Ergon 3 chairs.
This cylinder can successfully be used on a standard Herman Miller Ergon 3 chair, to convert it to stool height, standing desk, sit-to-stand desk, or bar height. Also available is our full stool conversion kit (including foot ring) for the Herman Miller Ergon 3 chair.
If looking for a standard stool height, please consider the 8″ stool cylinder, the 10″ cylinder provides a significant increase in sitting height of the chair, and should only be considered if the 8″ stool cylinder does not reach high enough.
- Overall Length / Maximum Extension: 28.25″
- Overall Length / Minimum Extension: 18.50″
- Amount of adjustment: 9.75″
We have included installation instructions to help you install your aftermarket replacement stool gas cylinder (same procedure as a standard gas cylinder), but please feel free to contact us with any issues or questions.
