Spidfee Fix Sinking Office Chair Saver, Adjustable Height Chair Repair, Stainless Steel, Silver

This product should be furnished with every 'pneumatic' chair sold. I have fought with my 'pneumatic' chair from the first day I brought it home. Because the mechanism of the chair is chrome plated it was not something that could be welded easily to a fixed height. Turns out you can't buy a chair with a locking mechanism to force the chair to stay at a fixed height any more - at least none of the stores I checked had even one. I love the chair now that it is at a fixed height. No more jerking as the chair slowly lost air from a leaky seal. Incidentally, my chair doesn't have a manufacturers label on it nor an instruction on it to help use theadjustment mechanism. That shows me that the manufacturer was really really proud of their prodcuct.

The product is very easy to install, and comes complete with the necessary Allen key. It certainly does the job it's intended for.

The hydraulic cylinder on my office chair began to give out months ago and I literally had stand up, raise the chair back up several times an hour.I was literally about to spend hundreds on a new chair and came across this.I literally just got it and installed it in just a couple minutes. No sinking whatsoever. Looks way better than a cheesy hose clamp. It looks like it is just part of the chair.$10 bucks just saved me hundreds!

Sadly this piece of hardware probably could have been picked up at a Home Depot type of store for a few dollars. After a couple of weeks it didn’t keep my office chair from sinking. Probably will need constant tightening to do what it’s supposed to do.

It has been a year and this saved me the cost of a new gaming chair - my preference for a work chair. Very happy and would recommend.
