Omyoffice 5.5” Office Chair Gas Lift Cylinder Replacement, Class 4 Piston

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!

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.

I've had two of these chairs in the past and both had the same issue. This chair was given to me by the company to promote and it's one of their more expensive lines. Sadly it's in generic red and not purple loke my last one that was their base line. But the both has the same problem the lift went out. So the chair it's self is very comfortable and this one has the Bluetooth speakers in it so I be damned if I was gonna throw out a FREE BLUETOOTH ENABLED CHAIR. If I get another chair by then I am definitely going to be buying this along side it to use instead of the stock cylinder give. The old one was a pain to get out but easy to install the new one once it was out in. I can definitely tell a difference because this one is def more study than the original one.

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

Bought replacement to fix favorite realspace desney chair I had bought to work from home during pandemic. I am a big guy 6'3 375, and the cylinder for the chair gave out, it had been out a while. Decided to take a look at replacement cylinder to fix rather than replace favorite chair. First of all the hardest part about replacing cylinder was removal of cylinder. The following is soe advise to do so. You will need a rubber mallet or hammer. WD-40 and a pipe wrench. 1. Spray wd-40 around base of chair where cylinder connects to base. let sit overnight if possible. 2. To remove cylinder from bottom of chair use pipe wrench grip firmly a couple of twists later top part of cylinder is removed from chair. 3. turn base over use square wooden block over the base part of the cylinder sticking out the bottom of base. And hammer out. 4. After old cylinder is out line up new cylinder remove cover at top before sliding into the bottom of seat Just some advice to help anyone out there, Like i said I am a buy guy pretty sure the old cylinder was pretty in there. New cylinder appears to be sturdier and higher for sure. Chair is comfortably at typing height on kitchen table. Would definitely buy again.

Before attempting to replace this cylinder search YouTube for "chair replacement cylinder or height adjustment cylinder" and watch these videos. This will make the job a bit easier. I have to replace the cylinder on a Bayside office chair and it was on "hard and tight". I had to use a black smith hammer and heavy duty pipe wrench to get it off. But it did come off nice neatly after some arm wrestling. Just follow the videos and use leverage and common sense.

This was a chair saver. My office chair had sunk to the bottom and was about to be tossed when I found this repair kit . It saved me from having to buy a new chair and was very easy to install. It has great stability and is very easy to adjust.

It works great... I think. Its lowest setting though is higher than my old chairs highest setting. Its the tiniest bit too tall for me but not egregious. Fore reference I am using a normal office chair and I'm 6'.

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).

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