Not 1000lbs (greatly exaggerated / false). Ignore that fake spec.Cylinder says Class 4 SGS BIFMA X5.1, so I assume it will probably tolerate a few hundred pounds.Getting your old cylinder out is the hard part. You hit the larger exposed side with a hammer until it pops out. The smaller side you need a HELL of a pipe wrench or big vice grip and rotate/smack it out, ideally after applying penetrating lubricant.Install is easy provided you get the old one out.I made sure to shake the cyclinder well before install and apply a small amount of lithium grease to the head where the shaft slides. These steps can prevent immediate failure.

This cartridge was a perfect fit for my Staples brand office chair. When you are preparing to remove the old one, prepare for some muscle work! I used a vise grip, pipe wrench, and a hammer. The big pipe wrench gave me the grip and leverage I needed to twist the cartridge out of the base. The wrench was too big to grab the chrome tip near the seat, so I used a vise grip and beat it with a hammer to remove it. Very satisfying! The new cartridge just drops in place. When you place the seat on top and sit down, the installation is done! My chair is like new again.

The Omyoffice Office Chair Cylinder Replacement was exactly what I needed to fix my sinking chair. The heavy-duty Class 4 hydraulic piston feels solid and reliable, and it works like a charm. Installation was straightforward, even for someone who isn’t super handy. Now my chair is as good as new and adjusts smoothly without any issues. If your office chair is sinking or not holding its height, this replacement is a lifesaver. Great quality and worth every penny!

The product didn't work. When I put the replacement into my chair base, the hydraulic components did not work so I could not adjust the chair. It also prevents the chair from not leaning back. It also immediately became stuck in both the chair wheel base, and the hydraulic chamber so I have to replace both, which is 3 times the value of the cylinder in the first place. Spoke to customer service about it and they refused to do anything but send a replacement cylinder, as if I would use it in the first place. Horrible product.

I came across a Herman Miller Aeron at a used furniture store for less than $100, and since I had been considering getting one, and a good refurbished one still costs $400-$600, I figured it was worth a show fixing it up. The cylinder in the air didn't work, and would slowly settle down to the bottom with any weight on it, so I bought the chair, this cylinder, and a new set of casters all in for less than $150.The hardest part about the whole thing was getting the old cylinder off of the chair (I ended up using a hammer to loosen it after getting nowhere with a pipe wrench). From there, it just took a minute to get the new cylinder in and then get the height adjustment lever properly adjusted.I can't speak to the long term use of this cylinder yet, but so far, about 2 months in, I haven't had any issues.

I used this particular cylinder to replace the leaking one on my 6 year old Serta "Big & Tall' office chair. Removing the old cylinder from the chair base was the hardest part, but after reinstallation it worked perfectly... almost!The only downside is that the chair sits almost as tall as it did on the new lowest setting as it did on the medium/high setting on the original. That being said, i cannot lower it to push it under my desk anymore, and fully extended, my feet are easily off the ground (im 6'2")Not a huge downfall, but be sure to measure your original cylinder size before ordering a new one if you want to retain the original height and settings.That being said, it really is a good, high quality piece that fit the base of my chair perfectly. I just wish it sat a little lower, but i can live with it versus replacing my chair completely.

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.

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.

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).
