Office Chair Gas Lift Cylinder Replacement, Hydraulic Pneumatic Shock Piston Heavy Duty (330 LBS), Highest END Class 4, (Chrome)

I always felt my office chair was too low for my desk, but put up with it since I only spent some time in the office. Given the COVID-19 lockdown and working from home, I felt it was time to upgrade to a new chair. As I was researching, I came across some information regarding the gas cylinder. There was nothing wrong with my cylinder and it worked fine, it just was not high enough for my oversized desk. I did some research and rather spend $300 on a new chair, I thought I would give the cylinder a try for $20. The description is exactly correct and while I struggled a little removing the existing cylinder (check out YouTube on how to), the replacement was simple. Best of all, I just gained what feels like an additional 4" in height!! I liked this so much, I ended up buying another one for a different office chair. VERY pleased with the outcome. Best of all, I was expecting the product to arrive on 4/22 and it came on 4/18 - four days early! Overall, very pleased with the product and seller.

I'm 6'2" and just got a new office chair. The new chair is great, but I found out it had very little height adjustment. It was too low at the highest setting! I took a risk and bought this replacement chair lift. After some pounding with a rubber mallet to get the other one out, this one is great because: 1. Fit chair perfectly 2. Worked with existing hardware for seat adjustment. 3. Not only gave me the few inches higher that I needed, but about 2-3 more. My guess is with a standard chair, that it would work for someone up to about 6'4" - 6'5". 4. Price was very reasonable 5. It shipped Prime, so I had it in 2 days. One of my best Amazon purchases this year. Very happy. Threw old lift in the trash.

It is the same size as the one that came with my chair ( thr one on the left is the one I'm reviewing) so I was immediately upset but now that I have installed it I am pleased with the results. I wanted more height even though I'm short. I don't like how short thr gas lifts that come its the chair are. Neightwr does my daughter. We both like to put our feet up anyhow and do not like brushing them off the floor. So maybe I'll get her one too. So yes it was easy to install took a few minutes cause thr top part of my chair is heavy and the wheel part was rolling away.

Works exactly as described. Used a hammer top pop out the old base, used a pipe wrench to spin the post loose from the seat. From start to finish, less than 5 minute project

It is defiantly as stated, chrome, long and holds a lot, but that's what I wanted !. The hard part was getting the old one out of the chair base.....I put a pipe wrench on the shaft of the old one and was able to remove it from the chair, then took the base with lift attached to it out to the garage and set in my bench vise ( nice big Wilton ) and with a 3lbs. sledge hammer and 8" long chunk of wood I was able too smack it with a couple of good blows and POP !!! there she goes hitting to floor like a bullet.....keep your feet clear mates !!, The pipe wrench left deep gouges in the old shaft so if you are planning on reusing the existing gas lift you are trying to remove.... you might want to rethink the method in which it was removed by Me ? , so the old one went it the garbage, I installed the New Office Factor Chair gas Lift and all is Golden !!

The part was easy to install, removing the old part was the most difficult. I used wd 40, a hair dryer, and a Mallett to remove the old part. A few rounds of spraying, warming, and banging it over a utility blanket. Previously my lift didn't go high enough for but this one raised my chair high enough for me to sit comfortably using a standing desk converter. I also like that the height increase/decrease smoothly in small increments. Definitely perfect for someone 5'6 to over 6ft tall.

I am 5’6”, this piece is perfect height for me! My chair still adjusts very nicely and smoothly with this replacement piece. Would buy again!

Very easy to put on a chair, goes up and down as it should. Makes my chair go super high which is great since I'm 6'1" and my desk I built sits higher then most desks as well. All stock gaming chair lifts don't go high enough this solves it.
