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.

My new computer chair came with a pretty long cylinder so I bought this one and it works great. Exactly what I was looking for.

Short people problems... I upgraded my wheels and found my feet barely hit the ground. I did some research and found this lift cylinder. And....... I love it. so much better.... Short people should get paid more for having to deal with this problem.

Bought this for my Staples Joel chair, and I'm finally able to sit at the correct height with the chair all the way down (I'm 5' 5"). However, like a lot of other people have said, the chair is pretty wobbly. You can lean in any direction and feel the chair slightly silt, which is honestly kind of annoying, especially coming from a chair that had zero tilting problems. I'm still more thankful that I fixed my height problem, but I will be looking elsewhere for a similarly sized piston that may be made better.

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.

This lift is the same exact match for a SecretLabs or similar chairs ( MainGear in my case) that uses a short lift. It was the same exact measurements as the original lift on my chair. Lift looks like high build quality and durable . * important : Make sure to use some grease on top and bottom on the new lift so in case you need to remove the lift later, it does not get stuck. *

Bought this back in August. Seemed to work well so I bought a second one for another chair. Welp, after only a couple of months this first one has stopped working. It no longer keeps the chair up - constantly drops. I bought this because it was heavy duty and supposed to support a lot more weight than what I weigh. Too late to return it, of course. I use this chair everyday. I will try a different brand (though I think all of these are made at the same factory and sold to different companies). However, first I am going to try to get it out of the base attached to the bottom of the chair. I never could remove the original one (from either chair), no matter how many videos I watched, and how easy they said it was, and trying several different ways it was suggested to have it easily pop out of the base. I ended up having had to buy a whole new bottom piece for both chairs as well. I am now concerned the second one will fail too. I don't use that chair as much (it's in the basement with my craft area) so we'll see. If I can't get it out of the base I'm not sure what I'll do. Buying a new chair would probably be cheaper than constantly having to replace these faulty, poorly made pieces.
