Fit my Steelcase Amia, seems to be great quality and works perfectly!

Exceptional fits my GTPlayer Racing chair like a chair, slightly higher by lick and in or 2 but its easliy adjustable! Removing my old on was a pain but installion of this was a breeze. It lloks and feels strong, if there is no update, that means its still working great!

So far, it's working fine. The only issue is that the lowest setting is almost too high. But that's my fault for not paying attention to the specifications. Luckily, I have an adjustable height desk.

Excellent quality, easy install

Our Quill Hazen office chair had a base recall, they sent a replacement for it and the chair began to lower on its own while sitting in it. We're not sure if we accidentally hit the center of the original cylinder or if we had exceeded the weight allowance, as I'm around 220lbs and our toddler will sit on our lap at times and he's around 40lbs. Due to the cylinder not remaining at our desired height, I began searching for a replacement cylinder that would hopefully last for at least the duration of the chair, with us having a growing child. This cylinder caught my eye, due to the weight allowance and 5 year guarantee, and placed the order. This gas lift cylinder included the gloves pictured and a business card that says to search for instructions online on how to replace the cylinder. The included gloves are of decent quality and have been added as a keeper in the toolbox, which have already been used for projects since changing the cylinder. Removing the current cylinder is easy enough using a rubber mallet or hammer and a wrench or a pair of vice-grips. This is a slow and steady project and should not be rushed, otherwise you might break something in the process and will need to replace even more. 1. Raise the chair to the maximum height (this makes step 4 easier). 2. Lay the chair on the floor. 3. Using a rubber mallet or hammer, hit the outer ring of the current cylinder, not the inside, while holding the wheel base until the 2 become separated. 4. Using a wrench or vice-grips, rotate the cylinder where it connects to the chair until it disconnects. You will more than likely need to go different directions to fully get the cylinder to release from the base of the chair. If using vice-grips, its easiest if they're applied at a horizontal direction and you're able to push from the top downwards. 5. Place the base of the chair, where the wheels are located, in the upright position (the direction that it will be once the chair is fully assembled). 6. Insert the large end, non-red cap, into the center of the wheel base. 7. Remove the red cap from your ToolKee gas lift cylinder replacement. 8. Place the chair on top of the gas lift cylinder and wheel base. This took approximately 10 minutes to install, due to getting everything ready to take the old cylinder out, doing the removal, installation and cleanup. We've had this for almost a month and have not had any issues, even though we have a little director of operations that likes to periodically give himself a raise, while sitting in the chair. I would definitely recommend this gas lift cylinder as a replacement to any office chair, as it was easy to install and can support quite a bit of weight.

A perfect replacement...More workable/durable than the OEM unit which came with my office chair. Pricing is right on. Just follow the simple instructions for replacing the your cylinder. I needed a larger pipe wrench that initially anticipated to remove the old cylinder.

Little harder to adjust up and down because of the pressure of the cylinder, but, so far so good. Much cheaper than buying a new chair and took all but 10 minutes to install with a couple clothes and a small hammer to nudge the old one out of the chair seat. Ill update if it goes out within a year.

It's ok,but I have returned this , quality ok, fit , stability not good assembly very nice stability ok, functionality ok

Seems like a universal fitment. Worked perfectly for me. Measure your old gas cylinder and ensure its the same height. I removed the black case because my chair had a different design however the silver part was standard size and fits well. There's small parts inside the black cylinder so be careful not to loose anything

Fits well, make sure to measure the travel of old one as majority on here were actually shorter. Need hammer/mallet and a pipe wrench to remove old one. Simply mallet hit bottom to loosen from cylinder and years of sitting in chair, top chamber pipe wrench needed to spin about to loosen from chair. Then simply remove the new cap on the new cylinder and place in the feet and then top chair and sit on chair and move up and down a few times and then it’s like new

I can't say enough about how incredible this product is. I bought a very expensive showroom demo office chair for $100. I then realized that it is possible to use this product to revive the chair to 'like new'! I suggest you don't throw out your beloved office chair and just put in a new lift. It takes some elbow grease getting the old one out, but you'll feel accomplished and pleased with this product. Give your chair some surgery and don't kick it to the curb😿

So far so good n satisfied with the item
