MySit 5.5" Office Chair Gas Lift Cylinder Replacement Parts, Heavy Duty 450lbs Long Stroke Hydraulic Pneumatic Shock Piston Universal Size Fits Most Executive Chairs, Gaming Chair, Class 4

Very pleased with this, it works beautifully. Dropped my chair down far enough that my feet could be flat on the floor. Definitely recommend for short people. It was easy to install, and it came well packed. It is worth the price.

This shorter lift cylinder perfectly replaced the standard lift cylinder in my Titan XL chair from SecretLab, the gaming chair manufacturers that sell overpriced computer chairs. Seriously, these chairs are basically the Alienware of gaming chairs. They're nice and all, but they fall apart easily just like all the other ones, but you're paying for a name brand now 'cause they spent so much on advertising.Anyway, the lift cylinder replacement was pretty each, provided you have a heavy rubber mallet and a vice. I tipped my chair over, smacked on the chair portion a few times and popped it off the lift cylinder, then set the base in the my vice (upside down) and smacked the cylinder out of the base. Installing the new lift cylinder is just dropping it into the base, then setting the chair frame back on it.Note: the cylinder cover that comes with the chair will prevent the shorter cylinder from seating properly into the chair receiver, so I just tossed it in the garbage.I wrote to Secret Lab and tried to get the exact dimensions of the cylinder to ensure that I was ordering the correct one, but Lance was being all evasive and refused to answer the question. He will let you know that you might void your warranty if you modify the chair at all (good up to 5 years). I didn't mind, though 'cause my chair is over 5 years old and modern products are designed to fail in some way about two minutes after the warranty expires anyway.I upgraded the wheels on this chair, too, so it slides nice and smooth now. You can pay SecretLab $50 to send you in a couple weesk the same set you can get on Amazon for $30 in two days. That's an option, but not right now 'cause it's out of stock, but Amazon still has like ten thousand in stock from like fifteen different vendors.So, if you got gifted a SecretLab chair like I did and ended up having a frustrating experience with their customer service, you're in luck: you can upgrade it with standard office chair parts 'cause as unique as they advertise they are, they just use the same cheap garbage everyone else uses.

For any 'vertically challenged' individual out there who may be thinking about purchasing a new office chair because of backaches, neck pain or thigh pain due to your current chair....try replacing the cylinder on your chair with this one first. You will not be disappointed! This cylinder will drop your chair by a few inches. This cylinder will allow your feet to be planted firmly on the floor and your thighs will be perpendicular to the chair seat as they should be instead of the constant slight hanging/downward pointing. It took approximately three to four days for all the pain in my neck/shoulders, low back and the backs of my thighs to subside, but I could feel the change instantly! I never knew that such a thing existed! It had never occurred to me to switch out the cylinder on the chair! I have been through many office chairs over the years trying to find one that was suitable for my short legs and was actually shopping for a new one when I stumbled across an office chair review that mentioned the purchase of this cylinder. My current chair is ergonomic however it just did not go as low as I needed it to. Working from home due to COVID all day every day, the chair began to really effect my body in an extremely negative way lol...Now, with the ergonomic chair and this new cylinder, I am truly comfortable while working in my home office! Just remember to remove this cylinder if you ever do purchase a new chair!

I needed a replacement cylinder for my older chair but was having a hard time even removing it. First off the tool worked lovely and was infinitely easier then whatever I was doing. My only real complaint is the replacement cylinder it comes with is REALLY high. Like if I put it all the way up I have to actually jump to get on my chair. If I put it all the way down my chair still doesn't fit under my desk. So now I have a working cylinder put I have to sit an extra foot away from my desk, I guess you can't have it all. It was easy to install (and uninstall my old one) 5* there, if you need a cylinder this high it's probably a 5* for you there also. As far as comfort goes I have to rate it a 1* for ME PERSONALLY because I'm gonna have to replace this cylinder it's WAY TOO HIGH. If you're looking for something that goes high though this is the cylinder for you. The tool is also pretty priceless lol

Short girls keep your office chairs! This lowered my chair to the perfect height. I'm 5'2" and was dreading needing to return my new desk chair until this came across my feed. It was difficult to get the old pump out but this puppy luckily fit perfectly to replace the one my chair originally came with. Save the hassle of searching for a short leg friendly chair and use this to replace the standard height pump. It costs less than a replacement chair and works as listed. I'm very happy with this purchase!
