First of all. The piston itself is fantastic and sturdy. It is a little longer/taller than my old one so it makes my chair taller at the full extension. I don't mind this, I like my feet to dangle since I put my feet on a footstool. Do make sure to take off the small plastic cap at the top of the metal rod of the cylinder before installing or the mechanism to lift and lower will not work. That being said, the cons have nothing to do with the product itself. The hardest part of this whole process is getting your old cylinder out of your chair. At least, it was for me. After watching a couple videos of how to remove the old cylinder from the chair, I set down to take it apart. Mind you, I'm no small girl at 5'5" and 250+ lbs. Taking the star base of the chair and cylinder apart was easy. I just alternated pounding the bottom part of the cylinder and the star itself until I could pull it off. The casters came off during the process, making my cats scatter in pure terror. So...pro tip. Take off the casters. Next came the detachment of the cylinder from the bottom of the chair. I used the items they gave. The two collar type mechanism where one is supposed to be loose against the bottom of the chair and the second one is tight on the cylinder itself. In essence and theory, the tight collar is supposed to stay still while you thread the bolts through the threads and push the cylinder out of its snug little home. Sounds easy right? It should have been but the tight collar kept slipping for me. Threading the bolts only pushed the tight collar down the cylinder rather than pushing the cylinder out of the bottom of the chair. It was a rather ineffective way to pull the cylinder out for me. Frustrated and with the might of Thor running through me, I got a mallet and tried to lift the chair as I hammered the bottom of the chair. Much to my chagrin, the cylinder would not budge. Even after the application of penetrating oil. I even tried a regular wrench but only succeeded in scratching up the old cylinder. Fast forward two days later and I went to Lowe's and bought myself a 14" pipe wrench. Who doesn't need a pipe wrench in their tool box? I felt like a true, diy woman of distinction as I bought these heavy inches home. As I sat down and put the wrench to the old cylinder, I knew I was going to make it my new female dog. It was reluctant at first and I had to figure out the best position for leverage and I pushed and pulled with all my weight. After about a minute, the cylinder was out. As I belted my yell of victory and raised my hammer...er wrench above my head, I stood over my defeated enemy. My cats could finally live without the fear of loud pounding and they swarmed the enemy to further humiliate the old cylinder. Attaching the new one was easy, simply slipping into place so that I could finally claim my throne. So...tl;dr. Get yourself a pipe wrench, some penetrating oil and some brawn. The product itself is great but the tools provided may or may not work.

First off, this is a great deal. I paid more that twice before for essentially the same product from another vendor and it was delivered quickly. Time will tell if it lasts but there are no problems in the first two weeks. Removing the old cylinder can be really difficult. I've done this repair now on two different chairs. On the first one, the removal tool worked great to remove the cylinder from the seat; popped right off. Getting the cylinder out of the base required really smacking it with a hammer but it did come loose. Make sure you use a block of wood to keep from damaging your chair. On the second one, it was hell. I used a small sledgehammer to get the cylinder out of the base. Since I knew what to expect, a couple solid hits took care of the job. Getting the cylinder out of the seat, however, was nearly impossible. The removal tool did not work after many attempts. I tried various approaches with vises, wedges, etc and none worked. Eventually I put so much pressure on the cylinder, it broke. Still, the cylinder did not come out of the seat. I was resigned to having throw away the chair and didn't care what I did next. I removed the metal bracket under the seat and put the cylinder hanging down through a gap in my portable workbench. I drilled a hole in a piece of scrap to put between the bracket and the bench. I needed other wood scraps to steady the bracket. I put various tools against the end of the cylinder and whacked it with the sledgehammer. It wouldn't budge. The end of the cylinder was falling apart yet it didn't come free. I was sweating, swearing and pissed off and wouldn't give up. After maybe the 20th hit, the cylinder finally popped off. Five minutes later I had screwed the bracket back on the seat, inserted the new cylinder, stuck it on the base and rolled it into the den. Easy! Bottom line: the cylinder is fine and, probably in most cases, the removal tool will work easily. But, don't be surprised if getting the old cylinder off is a nightmare!

I ordered this cylinder to replace the cylinder that came with my refurbished Steelcase Leap Chair v1 that I ordered in March 2020. TL;DR The cylinder needs modification in order to work with the Leap Chair v1. You may want to look at different cylinders if that is the chair you have. The cylinder fits in the chair perfectly and seems higher quality that what came with my refurbished chair. The installation kit was excellent, the hardest part was removing the old cylinder from the base. If you don't have a rubber mallet, go to Harbor Freight and get a cheap one. It makes removal much easier and quieter than using a board and hammer. With regards to the Steelcase Leap Chair v1 issue: the plastic button at the top of the cylinder that activates moving the chair up or down is too tall for the Leap v1, the button ends up always being activated. If you take a hacksaw to that plastic button and cut it off flush with the metal cylinder housing it will work. The portion I cut through was all plastic so I don't expect any issues. I did have to put the set screw under the seat almost all the way down after cutting the cylinder activation button. Prior to that I had almost removed the set screw to attempt to get the cylinder to work. When I initially got the cylinder I contacted support and they got back to me within 24 hours and once they had a good understanding of the issue they sent me a second cylinder to try. This cylinder had the same issue when it came to my chair because the issue is not a defect but rather an aspect of the design. I was offered a refund, but at this point I decided to try cutting the button down and seeing if it worked. It did, so I declined the refund. While I wish the process had been a bit faster and it had worked with my chair out of the box, I can't complain too much since my chair works at this point.
