5.5 inch Office Chair Cylinder Replacement,Heavy Duty Gas Lift Cylinder for Office Desk Chairs/Gaming Chair,Gas Lift Hydraulic/Pneumatic Piston, Universal Size (Silver)

Installed same day. Fit perfectly on my N-Gen chair. So far So good will update if any issues arrive but it's working. Worth the price.

It fits perfect to the chair and saved replacement cost. Working as new

Do not attempt this replacement if you are without at the very least average mechanical skills. You will need a hammer and a steel punch to extract the cylinder by punching it on both ends. It has tapered ends top and bottom. Don’t drop it on your foot and also, don’t forget the plastic dust covers . They are installed from the top . At my first use it does appear to be heavy duty .

Original bought the chair from biglots at local store, chair from day one has these issue where moment i sat in drop bought half inch and popped up when i got up it also creep down slowly at random whiling sitting in it, i ignored it cause was not bad and the chair was comfortable in last month starting 5-01-2023 it start sinking 1-2 inchs just from me sitting in it and sinking while sitting in it alot to point i would have pull the lever just to make go back up which wasn't making it go up ( had to pull up) On 6-10-2023 the lift was lost on cylinder. So I bought it next day it was sale go figure. New cylinder works great for now ( and i hope permanently), I only way 110lbs this rated for 1000lbs so this should have zero issue any time soon i hope. Seeing I spent 30 minutes the other day just removing the old cylinder, This was easy to install, put one end into wheel side and other in to chair ( dont forget to remove cap on top cylinder so will go up when pulling the lever). Now the chairs max height was bout 1" higher then the old cylinder, but I adjusted it to height needed, I now have zero drop in height when I sit in it. and staying at height i need. Was not really happy that box that cylinder was in was open cylinder fell out box as grab box out brown bag it was in and plastic bag the cylinder was in was open too the rest of plastic bag in it where sealed. And seeing as I need cylinder I just use it as it didnt look damaged If it goes bad I will update

Fast shipping. Very good fit and works good.

I had an office chair from OfficeMax that was slowly bleeding down. This part fixed it. I did have to resort to some tools many homeowners won’t have. I had to use a big pipe wrench to get the top loose from the seat mount and a big hammer to drive the cylinder out of the base. Price is great! High quality! Has a huge lift, like feet off the floor height! Immediate shipping!

My office chair was sinking and I was dreading replacing this cylinder as it looked kind of daunting. The YouTube videos I watched seemed pretty easy. If you follow them, it is actually pretty easy. This cylinder was higher than my original, but I actually like it.

I had an office chair whose cylinder was failing. It was much cheaper and less time consuming to get this replacement cylinder instead of trying to find a new chair to buy. Getting the old cylinder out was a bit difficult but installing this replacement cylinder was very easy.

Followed the instructions provided under the product specifications and easily replaced the component. Works perfectly fine and better than the existing one i had in the chair. Highly recommend if you are looking to buy.

Hola, he comprado este cilindro para una silla que compre y me llego sin cilindro, ya puse este cilindro y no se si no le quedo o lo estoy instalando mal pero no hace la elevacion. Le mando fotos para que me indique si estoy haciendo algo mal o es que no es de la medida para la silla. (Creo que debo quitarle ese como tapon verde pero no quiero hacerlo sin estar segura).

Ajusta sin mayor problema, totalmente estándar

Exactly the item we needed to repair our old office chair. All good.

Arrived with no instructions - I googled it to find out how to remove old cylinder and installed this new one....ended up with a chair that does not adjust in height or bounces a bit for a soft landing. At least it does not shrink down when I'm working on it. I bought a more expensive version so I was hoping for better. At least it swivels and is set a height I can use - and the white trim matches the chair. Disappointed with Staples for selling me a chair that had a hydraulic that wore out within a year and not impressed with the replacement I purchased here for more money.
