Brought new life to an old chair

    • A perfect replacement for an office chair that was too low
Color: Black
A perfect replacement for an office chair cylinder that was too short. This cylinder gives a wide range of height and has turned my home office space into a more ergonomic environment. Installation is easy once the old cylinder is removed. WD40 (or similar spray lubricant) plus a pipe wrench or vice grip was key for getting the old cylinder off. Here’s how I went about removing the old cylinder: 1. Lubricate both ends of the cylinder attached to the chair (that’s the base attached to the wheel spokes and the top attached to the chair’s lifting/lowering mechanism). 2. Put the chair sideways on the ground, or on a protected work surface. 3. Tighten a pipe wrench or vice grip around the top of the cylinder, as close to the chair as you can. Leverage the wrench downwards to twist the cylinder around. This took some elbow grease for me, but I was eventually able to twist the cylinder in one direction enough for it to come loose and come out. 4. Now you have just the old cylinder attached to the wheel spokes. Give the cylinder a few sharp taps from underneath the wheel spokes with a hammer or rubber mallet. It should pop out eventually. 5. Drop the new cylinder into the wheels and place the chair on top of the cylinder. Done! This cylinder is an inexpensive option to change the height of an existing office chair! ... show more

    • Took some finagling but I got it!

As you will see in my video, I do recommend this product, it was probably overall easy to install for someone who works with tools on the daily but that is not me. That alone is not their fault but detailed instructions would have been helpful. Especially the part about removing a little red tip on the new peace. I just about returned it because I could not figure it out. Once I got it after about 30 minutes of frustration, it did work exactly as described. And my chair seems to be working terrific. Four stars because of the lack of instruction. Not because of the quality of the product. It shipped very quickly and I've actually had it for a couple of weeks but didn't get to it. It's very quiet so far, and adjusts just as it states it does. As far as stability, I'm not a huge person but it seems to be a very nice item. ... show more

    • Great,used it on a Humanscale Liberty Chair
Color: Silver
I used it on a Humanscale Liberty Chair, it runs a bit taller than the original cylinder, but fits right in, and has a bouncy feeling also like the original. I loved the silver finish to mix it up on my black chair.

I sat down in my gaming chair and noticed I was lower than normal. When I tried to raise the chair up it was obvious my chair gas lift cylinder was shot. After pricing out a new chair I decided to instead take a chance on this cylinder thinking worst case I would return it if it didn't work. Well, it did and the install was easy to boot! Very happy my chair doesnt need replaced and that I saved a boat load of money! Very happy with my purchase! ... show more

    • Perfect fit
Color: Black
Our air lift broke on our expensive game chair. I looked into just replacing the lift chamber and found this one as a replacement because of the weight it can hold. When it arrived I opened it up, took the red cap off the top, and slipped it right in where the old one was. Got everything back together and it has been working great! Saved me so much money replacing this instead of buying a whole new chair. ... show more

    • Worked for repairing a Costco Bayside Mesh Office Chair - FOR REPAIR HELP ON THIS CHAIR READ HERE!
Color: Black
Totally worked, but was a bit confusing as the Costco Bayside mesh office chair has a cylinder housing built into the base. You WILL need a pipe wrench to repair the chair. - Instead of using the entire product, you're just going to remove the silver colored cylinder from the black metal housing the new cylinder comes in. Careful with the metal tab, washer and bushing! Don't lose it! There are YouTube videos on removing this clip from office chairs and sliding it back on. - First remove the clip on the bottom of the Bayside chair base. - Slide the base off of the old cylinder (suggest you do this outside- mine was leaking black fluid all over the place!). The old bushing, clip, and washer will fall off- you can discard (or save if you want) these but you won't need them as the new cylinder comes with new ones already on the cylinder. - Use a pipe wrench to twist the former cylinder out of the main part of the chair (youtube videos on this out there as well). It requires some effort- doesn't matter which direction- it's not screwed in, just tight. - Clean up the chair now if fluid is everywhere! - Rest is the reverse of what you just did, but inserting the new silver cylinder into the chair base, then securing it with the washer and clip (included with the new cylinder). - Remove the red protective cap on the new cylinder - Put the main part of the chair on top of the cylinder which is now already attached to the base. - Push down on it, sit on it and you should be good to go! Hope this helps. It's pretty simple but the main issue to think around is the base of this chair having the black cylinder housing built into it. Other than that, easy repair. Hope this helps! ... show more

    • Way too high!
Color: Silver
Unfortunately, this sat unopened for four months before I installed it. It ended up not being the right size. You measure and hope you get it right, but sometimes it doesn't work out. This ended up being too high of a pump for me - and I'm tall! The lowest setting isn't low enough for an office chair. My feet don't touch the floor. ... show more
