Review: Wow -- amazing product; easy install & works perfectly. Highly recommended - Every now and then a product just works exactly the way it is supposed to without any unexpected hassles. This $43 purchase is even better than the old cylinder and saved me from having to buy a new $500+ chair! The video and printed instructions were crystal clear and the whole process of removing and installing took a seamless 15 minutes. The gloves were an unused bonus that I will save for future tasks. Plus the package came 2 days early. I can't be any more appreciative of this company.
Review: Good replacement for Herman Miller Aeron cylinder - My 2002 Aeron cylinder blew (not bad since I sit in it every day and weigh 220, working from home for the past 2 years) so I was looking for a good replacement that didn't require ordering one through the local HM dealer. After evaluating many options I selected the Oasis kit - I looked at some two stage cylinders closer to the OEM but due to either shipment times or functional need (I don't need to go lower) this seemed like a good and affordable option. And the removal kit bits seemed like a good option after watching the numerous videos and reading plenty of forum posts about the difficulty removing old cylinders. Mine has been installed for 20 years, the past two with relatively hard use so I anticipated a challenge and it did not disappoint in terms of difficulty. I'll comment on the cylinder itself, and removal of the old cylinder as separate (but related) issues. The cylinder itself has worked great - as others have noted it does not sit in the base of the Aeron as deeply as the OEM cylinder, thus it does raise the maximum chair height by an inch or two. If this matters depends on the user - for me I wished for maybe another inch with the OEM fully extended - worked fine but the perfect height for my "desk" (a repurposed drop leaf table) would have been a bit higher. So this replacement works well - I have it lowered just a hair as the highest setting is a bit high for my situation but the flexibility is nice. Do note the instructions online for adjusting the lever screw that presses against the cylinder button - I did have to tweak mine a bit as the prior setting for the OEM cylinder was too long and resulted in the replacement not holding the height when seated but it's a quick and easy adjustment - works perfectly now. The button on the OEM part is shorter than the replacement so this was expected - but for anyone wondering the taller button on the Oasis does work with the Aeron! Removal of the old cylinder... I don't have a 12 or 14" pipe wrench and while I have a good assortment of tools wasn't that driven to get one for this project alone (since I've never needed one otherwise in 20 years of home maintenance). Prior to receiving this new cylinder I'd given removal of the old one a go using 10" slip joint pliers, vise grips, with no success. Soaked the joint with liquid wrench penetrating oil and was getting no result whatsoever. Not a budge. Again my old cylinder was well and truly lodged. So I was anxious to try the removal tool included with this kit and using it I was able to dislodge the seat from the post! So it does work - here are some tips for use: first my cylinder had spewed grease/oil when it blew so I found that just wiping the post with a dry paper towel/cloth did not get the post clean enough for the removal tool part that you clamp down to gain a solid grip. I used some simple green degreaser, then a run of rubbing alcohol to insure the post was really clean. Once I did that I was able to clamp down the collar (and do clamp it down tight!) and it held. At that point it was just a matter of slowly turning the "pressure" screws through the collar - 1/4 to 1/2 turn on one, then the other. I did find steady pressure on both sides worked well. If you go in smaller turns alternating each side you'll not need to apply a ton of torque to the allen wrench to achieve a result. I heard a fairly distinct pop when it first started to loosen and then it went pretty quickly - a few more turns and the seat detached from the post. So the removal tool does work with some patience and materials preparation. I've saved it for future use if needed. I do think it was easier than trying to torque it off with a wrench unless you already own a pretty long and heavy duty pipe wrench. Even then the screw pressure requires less oomph overall than even a pipe wrench I would think. Note that the removal tool gets the seat off but does not remove the old cylinder from the wheel base. Given the ability to use a mallet or dead weight hammer on the base (unlike the seat) it probably isn't needed but do expect to spend some effort getting the base removed as well. I used penetrating oil and a rubber mallet with little success. Here are my tips on that part of the job if yours is stuck. First expect to take some whacks at it - like maybe not 2 or 3 ;) I used the edge of my lower deck (around 2 feet off the ground) with some padding to make sure when it released it hit the ground and didn't take off a toe. You'll need a stable surface for sure. I decided to leave mine outside for an hour or two in 40s temps to shrink the metal and that seemed to help. I also alternated hitting the bottom of the cylinder with sitting the cylinder bottom on the deck and alternating hitting the base with a rubber mallet on opposing legs (which gets the benefit of the longer leg leverage, as well as some offset pressure to eventually break the seating). It did eventually release but it does take some time. Have patience! New cylinder install is super easy - I did put some "no seize" lubricant on each end of the cylinder to give some minor aid if I ever need to replace this again - whether it will help I don't know but can't hurt anything.

## Questions & Answers

**Q: 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?**
A: 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!

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

**Q: will this work with a dx racer chair????**
A: Yes, our office chair cylinder is compatible with dx racer chairs.

**Q: 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?**
A: 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.

### ⭐⭐⭐⭐⭐ Excellent replacement kit
*by B***H on December 21, 2025*

If I ever have to buy another office chair I will be sure to just order this cylinder replacement and install it, not waiting for the one that comes with the chair to fail, which it inevitably will and therefore save myself the hassle of going through the replacement process. Overall, it was easy enough, instructions were great and simple to follow, tool works well, and the cylinder is solid. What I most appreciate is it has added more than an inch of raisable height which for a tall guy (6’ 5”), I’ve never found a chair to go high enough for me. With this cylinder at its highest I’m on my tiptoes while seated. I was so impressed I ended up ordering another cylinder by itself for another of our sinking chairs and the roller blade wheels. All excellent and at a great value.
