DOZYANT Gas Lift Cylinder, Office Chair Gas Lift Cylinder Replacement,Hydraulic Pneumatic Shock Piston Heavy Duty (450 lbs) Universal Size Fits Most Executive Chairs, Highest End Class 4

Seems like a universal fitment. Worked perfectly for me. Measure your old gas cylinder and ensure its the same height. I removed the black case because my chair had a different design however the silver part was standard size and fits well. There's small parts inside the black cylinder so be careful not to loose anything

Product good but installation guyes faild to attach this to my chair

It's ok,but I have returned this , quality ok, fit , stability not good assembly very nice stability ok, functionality ok

Fits well, make sure to measure the travel of old one as majority on here were actually shorter. Need hammer/mallet and a pipe wrench to remove old one. Simply mallet hit bottom to loosen from cylinder and years of sitting in chair, top chamber pipe wrench needed to spin about to loosen from chair. Then simply remove the new cap on the new cylinder and place in the feet and then top chair and sit on chair and move up and down a few times and then it’s like new

Worked like a charm

Little harder to adjust up and down because of the pressure of the cylinder, but, so far so good. Much cheaper than buying a new chair and took all but 10 minutes to install with a couple clothes and a small hammer to nudge the old one out of the chair seat. Ill update if it goes out within a year.
