Industry-Standard Size

This pneumatic piston cylinder fits almost every office chair on the market, including Herman Miller Aeron. It has a 1-1/8" (28mm) diameter piston shaft and a 2" (50mm) diameter column. If it doesn’t fit your specific chair, no problem—we will take care of you.

Extra Heavy-Duty

Our desk chair cylinders are all Class 4, making them the most durable, long-lasting, and highest quality hydraulic gas lift cylinders available. Cheaper options can start sinking within the first few months, but ours don’t. They can even support up to 1000 lbs without fail.

Lifetime Warranty

Our goal is to provide you with the highest quality office chair parts to extend the life of your chair. If for any reason our cylinder fails, leaks, or starts sinking, contact us, and we will send you a brand new one. Our warranty has no expiration date.
