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.

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.

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.

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

Wish I had done this sooner! Fixed the dropping cylinder on my office chair.

Newly installed, so I may update this review upon further use. I want to give installation advice while my experience is very recent. The installation, as many here have stated, is very easy, just drop it in the base, place the seat, and done. To UNINSTALL THE ORIGINAL, however, use a hammer and a crowbar or demo driver (large, very strong flathead screwdriver) to remove the base, using repeated blows with the hammer, WITH THE CROWBAR/DRIVER POSITIONED ON THE BASE AT THE STEM. To remove the stem from the seat bottom, use the same tools, placing the crowbar/driver in a position that applies the force to the solid, larger part of the stem. It will more than likely take several very strong blows to loosen each end. I didn't see this procedure explained anywhere else, and I wanted to share while it's fresh.

So my Real Space DRG gaming chair was sinking. I read the reviews and checked that my chair was compatible with this Cylinder replacement. Google told me that my chair had the most common cylinder with a 2" (50mm) base. I ordered this Huiguli cylinder to replace my old one. Taking the old cylinder off was a little tough, as mentioned in many other reviews. I tried to hammer the swivel base with casters off the chair, but had no room to work and no luck. So, I unscrewed the baseplate from the chair. I turned the base upside down in my workbench and proceeded to knock out the old cylinder with a hammer. I destroyed it, because I had to hit it so hard and directly in the center to dislodge it from the base. But that did the trick. I then used vice grips to grab hold of the old cylinder and turned & "unscrewed" it from the base. The new cylinder was simple to put on. After screwing the baseplate back onto the chair, I then replaced the old plastic cylinder protector onto the new cylinder, then slid the cylinder into the baseplate. I then replaced the old base with the casters. The new base is fantastic. I have no evidence of durability because it is brand new. But, it works great and goes "extremely" high if needed. It is a little higher than the old base at it's bottom position, but that is fine, as the old one was very short at it's bottom position. I am extremely happy with my purchase, that came within 6 hrs of ordering. It sure beats having to buy a new $400+ big and tall chair.
