2-Pack Fix Sinking Office Chair, 304 Stainless Steel Office Chair Saver for Stop Sinking, Height-Lock Bracket for Failed Gas Cylinder, Adjustable Chair Height Without Cylinder Replacement

I am particularly glad that I bought the TWO Pack, just in case they do slip! As in the photo, I mounted them atop each other with about an inch above them, so even if that inch disappears, I still have a much better situation than without! I installed these four days ago and SO FAR, GREAT! I am NOT a light person (around 205 pounds) and these appear to be holding. I LIKE that they: 1) fit my 1+ inch chair tube as the ad says 2) come with some sort of plastic liner that is non-slip 3) have sturdy screws for severe tightening. I only gave them 4 stars for ease of assembly because I think they would be MURDER to install using the included 6mm hand held hex wrenches. Fortunately, I have metric wrenches for a socket driver. It takes TORQUE to fully tighten these that I doubt can be achieved with your fingers holding the wrenches, but they DO tighten with a good ratchet socket wrench! UPDATED February 4, 2024 - STILL HOLDING and I am NOT LIGHT! AWESOME! To those who still have slippage, MAYBE you need more torque when tightening. I used a high quality socket wrench!

This product worked great. Only suggestion is that before you install . Use a degreaser or cleaner to thoroughly clean any oil residue on the chrome hydraulic piston sleeve where the rings will be attached. This will ensure no slippage once you adjust and sit on the chair. Also , use both, one immediately over the other to ensure a solid adjustment for your desired height.

Easy to install on the chair and so far it is working great. The chair has not slipped down.

Affordable & so, so easy! While the stool may no longer be adjustable, it's at a functioning height. Great quality ~ works well.

worked like advertised.

If you are thinking about buying this because your hydraulic is going out in your chair and this could be the fix all. Lemme stop you there. It's not and it won't. This thing has been installed for about an hour now and I've fixed the chair 4 times. I have have the thing on as tight as plyers could get it and nope still goes down.

Honestly wish I would have purchased these sooner. I've been fighting a sagging drafting chair for several months while hoping the manufacture would respond to a warranty claim. The chair would suddenly begin to drop treating video callers to seeing my head quickly drop out of frame. Then have to stand up and adjust the chair only for it to rinse and repeat all day long. The brackets installed in less than a minute, the allen key is easy to use. They fit perfectly the first time and was incredibly easy to get at just the right height. It feels like there's nothing on the chair. 10/10 would absolutely recommend.

Okay. Put one on, after a day, chair sank. Put two on, and it is holding after 2 weeks.

works as advertised, cheaper quicker and easier to use highly recommended

Installing was easy. Works great, holds the seat up.

Easy to install, good quality. Only issue is the Allen keys provided were too small and had to use my own tools. Otherwise, would’ve been 5 stars.

The funny part is that for a while, lately, I was trying to find a cheap solution to my 'sinking chair' without having to scoop hundreds of dollars. I managed to come up with some methods to prop my chair up permanently and I was in process to do it when I came accross these brackets on Amazon. What a relief! These brackets did it for me in a clean, cheap and perfect manner. If you struggle with this sinking chair problem, I would highly recommend the brackets.

It worked!!
