I just installed this and my chair sinks when i sit in it and then rises when i get up. did i install it wrong or this doa?

Is there an adjustment screw someone above the gas cylinder on the chair that is connected to the lever that you pull to make the chair go up and down? I installed this on a 2003 Herman Miller Aeron and had to turn this screw out a few turns so it wasn't hitting the cylinder all the time. The button at the top of this new gas cylinder was 3/8" or so taller than the old one. I thought mine was DOA too, but then discovered this. Hope this helps!

Will this cylinder replacement work with a workpro quantum 9000 chair? Originally purchased from OfficeDepot.

No. I purchased this cylinder to replace the original cylinder of my new WorkPro Quantum 90000 chair, which sits too low for me, only to find out the height adjustment lever does not reach the button on top of the cylinder that unlocks it, which makes it impossible to adjust the height.

will this work with a dx racer chair????

Yes, our office chair cylinder is compatible with dx racer chairs.

I bought this and replaced it in my chair, now my chair is so tall I can't touch the ground even when it is lowered all the way. What did I do wrong?

Hi CatKenSyd, I'm so sorry to hear that the cylinder made your chair too high even if it's lowered all the way. I understand that this may not be a comfortable sitting position for you. Unfortunately, we do not have other sizes available for our chair cylinder. Given the circumstance, please allow me to fully refund your order. Kindly reach out to us at support@theofficeoasis.com and I'll help you.
