Fix Sinking Office Chair, Avoid Sinking of Office Chair Height-Adjustable Cylinder Replacement No Tools Needed

It work fie just as advertised. To add assurance I added a small strip of thin rubber to grab the column better. It works great. I do not claim this is necessary.

Works! It has completely stopped my chair from slowing sinking! I'm a big guy 350 lbs and it had no issues stopping the chair post from sinking. Easy to assemble and put on the post, but you MUST get is as tight as possible!!!

Gotta use the thumb screw because my piston is so small.

I was able to fix two desk chairs and make them look normal. Very Sturdy

Added this to another kind of clamp to my office chair. This clamp doesn't tighten up enough to hold.

It fits the cylinder but after a while the chair will go down by itself. Does not work. Found other that works

The kit i received had the new handle accessory but unfortunately the thread was not machined properly and it stops a quarter of the way down and won't go any further. It diminishes the quality of the item because these need to be adjusted every so often and now requires additional tools. I chose this kit specifically for the new handle and they highlight it in their advertising. Feel a bit let down.

Does not grip a standard chair seat pillar. It still slips, and you sink lower anyway. Not as bad, but you have to continuously readjust the device on the chair to keep the seat at the proper level. Not recommended.
