Huiguli Office Chair Cylinder Replacement - Heavy Duty Class 4 Hydraulic Pneumatic Gas Lift Cylinder(12" to 18" Adjustable, 1000 lbs Capacity) - Universal Fit for Most Executive Office Chairs

Excellent so far! Product seems as described and repaired my chair. Seems structurally better and definitely taller than my old one, also as described. Note: Cylinder arrived with a plastic cover on the top that was somewhat difficult to remove. Once it was removed it fit as expected and the height adjustment button was exposed to change the height of the cylinder.

Fit my chair correctly, not hard to install, worked , gave me a little extra height, seems solid and strong.

I weigh 300lbs and having no issues with it. Installed about a week ago. Seems solid. Much taller than I expected but that was just me not measuring properly and it still goes low enough for me.

It was fine. Served the purpose.

The Huiguli Office Chair Cylinder is better than I expected. I had to replace my home office chair's pneumatic lift cylinder as it would not stay up. The Huiguli replacement I purchased fits perfectly and actually lifts the chair higher than the original cylinder. The Huiguli cylinder was simple to replace, with the hardest part being removing the original cylinder. I recommend the Huiguli replacement cylinder to anyone who needs to replace what they currently have.

This item was an identical cylinder replacement for my gaming chair. Be aware that the difficult part of swapping cylinders is getting the old one out of your chair. It required that I beat the base and the actual seat multiple times to free each end. I would advise potential buyers to attempt the removal process before ordering. In conclusion, I'm very satisfied with this product.

This is perfect for raising my office chair in my craft room so it isn’t too low for my furniture. It brought my chair up 3-4 inches.

Update 9/25/2025: I was contacted by the seller and offered a refund on the product, which I accepted, eliminating the need for me to return this failed unit when the replacement unit from another company arrives. Had there been a direct point of contact for the product on the website (perhaps there was but I was unable to find it), I would have accepted a replacement product and given this company a second try. ----- No instructions or tools needed were provided, so I had to search YouTube for help. The 4 instruction photos in the Amazon product webpage are useless and unhelpful. I needed a BIG pipe wrench to loosen the cylinder from the top of the chair! A mechanic friend had such a tool and with his help, we were therefore able to loosen the old cylinder. Installing the new one was easy. However, the extension pole did not pop-up before I installed the top of the chair on it. I thought that once connected, it would do so but it has not. Chair does go up or down, so I am assuming that the extension tube is jammed and was like this when I took it out of the box. Of course, there isn't any support point to ask for help. I should have realized that I was going to have issues when afterwards, I noticed that there are only TWO reviews from the USA. Don't buy this product!

Purchased to give a favourite work chair a new lease of life. Fitted this which lifts a bit higher than previous. Very sturdy and no sinking. Good value for money and saved buying a new chair.

A high quality replacement gas lift cylinder for office and gaming chairs. This part allows one to extend the life of an adjustable office chair for years, rather than sending the chair to the landfill. A simple process to remove the failed cylinder from a chair and install the replacement within minutes. This particular part is heavy duty to support higher than standard weight and lifts taller than most standard cylinders and should last for years.

Has not let me down yet, literally, unless I want it to. I'm using it because I have very long legs and a desk on the taller side (80 cm / 31.5"). On it's lowest setting my chair seat is 53cm / 20.8" off the floor. It extends fully without issue and can take 100+kg of weight without significantly compressing. The only thing I find a little annoying is that sometimes I have to wiggle the chair to get the spring to move up or down. Other than that works fine as a replacement/ upgrade for my Secret labs Titan XL 2020.
