9 Inches to 13 Inches Office Chair Cylinder Replacement, 4'' Stroke, Heavy Duty 1000 lbs, Hydraulic Pneumatic Shock Piston, Universal Gas Cylinder Fit for Most Office Chairs, Class 4 (Black)

Bought this to replace the piston in my aging Vertagear gaming chair. Perfect replacement. Gives the same lowest level with an extra 1inch/2.5cm of height. Easy to fit, well packaged and seems to work really well. Only time will tell on its longevity. TOP TIP: Be aware that there are varying low and height differences so be sure to measure your existing pistons lowest, highest, overall length and travel length. It's also a good idea to check the taper at the bottom of your existing pistons as not all pistons are equal in this area. This one sticks through the bottom quite a bit so if your wheel base is low to the ground it will probably hit the floor before the wheels. In that case go for one with less of a taper so not so much of the piston sticks out the bottom of your wheel base.

The item arrived by the promised delivery date. It was relatively easy to fit and works well. The whole transaction was a breeze. Recommended.

MASTERY MART 9 Inches to 13 Inches Gas Lift Cylinder for Most Office Chair, Fitted a Corsair T3 rush gaming chair which the cylinder failed. I believe the Corsair chair has had two replacements cylinders with the last one lasting around 6 months before failing spectacularly. This fitted the gaming chair perfectly and is a good replacement. I'm hoping this last far more than 6 months so will update the review if anything happens. Installing the cylinder was easy enough i couldn't salvage the base plate due to the damage so i also had to replace the tilt plate and base with the wheel. Overall This so far is good and fitted perfectly well, good value comparing to the original which in my opinion fails fairly quickly and the person isn't at all heavy.

Was a good fit, functionally works, but has an issue of lifting it's self to full height over night from time to time, not that much of a big deal.

good product

Works very well looks stronger than the original one

Great replcement, nice to sit properly again! Easy to fit is you follow the giudes on youtube abd have a big hammer!

My 5 year old (but still very comfy) office chair had developed a tendency to lower itself at random, often in the middle of Zoom meetings. Having measured my existing cylinder, I ordered the required length and grith. This one seems to be a common size. It arrived next day, so I set aside a spare 15 minutes to fit it. It's just a tight push fit, but I had to get the old one off, so with my feet firmly on the base, and my hands clamped to the underside of the seat, I lay on my decking on my back, under the chair attempting to pull the two pieces apart. Lots of grunting ensued, but to no avail, although my neighbour wondered why I has having relations with a chair. Next came the lump hammer. A block of wood under the seat, and a well aimed clout with the hammer, and I had a sore thumb. My car jack was next, carefully placed on a block of wood. This separated the cylinder from the base! All I had to do now was pull it out from under the seat. Much more grunting and cursing later, and most of a can of WD40, I resorted to watching a YouTube video, which suggested using a pipe wrench. The young lady that was demonstrating it had no problem twisting the cylinder out, but I must be a bit weaker, as I had no luck, and had to hit the pipe wrench with a hammer. This worked! The new cylinder was a perfect fit, took seconds to put in place, and works perfectly. It stays up all night now and I have no worries about my nose and mouth slowly disapearing from sight in the middle of an important zoom call with my MD. Money well spent in my opinion. In short, if you can get the old one out, this one does the job perfectly!
