  • It Works
Color: Black
Original bought the chair from biglots at local store, chair from day one has these issue where moment i sat in drop bought half inch and popped up when i got up it also creep down slowly at random whiling sitting in it, i ignored it cause was not bad and the chair was comfortable in last month starting 5-01-2023 it start sinking 1-2 inchs just from me sitting in it and sinking while sitting in it alot to point i would have pull the lever just to make go back up which wasn't making it go up ( had to pull up) On 6-10-2023 the lift was lost on cylinder. So I bought it next day it was sale go figure. New cylinder works great for now ( and i hope permanently), I only way 110lbs this rated for 1000lbs so this should have zero issue any time soon i hope. Seeing I spent 30 minutes the other day just removing the old cylinder, This was easy to install, put one end into wheel side and other in to chair ( dont forget to remove cap on top cylinder so will go up when pulling the lever). Now the chairs max height was bout 1" higher then the old cylinder, but I adjusted it to height needed, I now have zero drop in height when I sit in it. and staying at height i need. Was not really happy that box that cylinder was in was open cylinder fell out box as grab box out brown bag it was in and plastic bag the cylinder was in was open too the rest of plastic bag in it where sealed. And seeing as I need cylinder I just use it as it didnt look damaged If it goes bad I will update ... show more

  • It fits well and it is comfortable. The quality of this watch band is worth the price.
Color: Black
Once I got the old cylinder off, the rest was easy. But I had to push down pretty hard to get the cylinder to work with the lever that enables the chair to go up and down. This issue was more about my chair than the cylinder. It is working well and is sturdy as well.

  • Like a rock!
Color: Black
This baby is solid! I bought a new chair and less than a month later it was doing the creep down every time I sat in it. I'm a big guy (300 lb) so I needed a heavy-duty replacement, and this guy is it. I switched it out on my chair, and what a difference. Set it at any height you want, and it is rock solid-not a bit of creep at all. I'm super happy with it and hope it lasts for the life of the chair! ... show more

  • Fix my $400 chair
Color: Silver
I like the unit as a came, installation was straightforward, but difficult to get the chair apart. I would definitely buy again if I have any more office chairs the break I will I will definitely use it again.

  • It finally gave out after 15 months
Color: Silver
The cylinder that came with my chair was awful. This one was great, until just recently and it finally pooped out on me. I do NOT work from home and I weight 200 lbs, so the fact is, it just didn't last as long as expected. Sadly, I have to use the one that came with my chair again, as I am almost on the floor now..lol Good while it lasted, and I suppose I got my $22 worth out it. ... show more

  • Perfect fit
Color: Black
I had to replace my old cylinder as it would just sink as soon as you sit on the office chair. Fast one day shipping and fit perfectly. The hardest part was getting the old one out. It took a little persuasion with a few hard smacks with a deadblow hammer. I would highly recommend.
