Fix Sinking Office Chair, Upgraded Chair Sinking Stop 304 Stainless Steel with Hexagon Wrench Adjustable Height Chair Saver kit with Leather Pads Support for Stop Sinking UIInosoo

I installed this clamp on my magnificent used 20 year old Steelcase Citation desk chair. Unfortunately, the clamp was not quite big enough to fit the shaft on the Citation gas cylinder, which is 1.25". Making it fit took all afternoon and a trip to the hardware store, but the end result is excellent. After fussing for an eternity trying to to do the impossible with supplied cap screws that were just a hair too short. In the struggle, I stripped the threads on one side of the clamp. Doing what I should have done an hour earlier, I retreated to Ace Hardware and bought longer screws, flat washers, and hex nuts. I had to drill out the stripped threaded holes in the clamp, put in the longer cap screws with washers and hex nuts, slipped the clamp to the right place on the shaft and tightened it down. Tight. My chair is now at perfect height and no longer sinks.You may ask why I gave a device that was difficult to make work a 5 star review. It deserves 5 stars because it would have been quick and easy if the gas cylinder shaft had been the size the clamp was intended for. The design and quality was good. If it had not been, my fix would have been impossible. If you know your way around things and tools, the product is great. If the clamp fits out of the bag, you should have no trouble even if you are not a tools and things person. If the product were a piece of crap, like so many are, I would not be sitting comfortably typing this review.

Installed it correctly, I weigh 119 pounds, chair STILL sinks when I sit in it. This device slows the sinking down at best.

I have had office chairs for many years. At some point, all the pistons fail not matter how expensive the chair. I have tried many fixes and the most effective, until today, was a short piece of PVC. But this clamp is $6, is screws together in 2 minutes, and my chair is no longer sinking. I am very pleased with this simple, effective, and inexpensive fix.

I have had my office chair for 3 years and it was beginning too not hold when I sat the height to its tallest. Instead of spending a couple of hundred dollars on a new one I bought this for 6 dollars and some change. When it arrived it took 5 minutes tops to install and it works like a charm. I have not had to adjust my chair sense. Safe yourself some money and buy this Chair Sinking Stop 304 Stainless Steel! Problem solved!!

I took a star off due to no instructions.Just installed this. It was very easy to install. Seems sturdy. Will update if I have problems with this. I wanted my chair at its highest point so it was even easier for me to install (didn’t need to mark anything). This is on sale right now for under $7, by the way. Not sure it’s worth its full price but maybe it’s always on sale.I’ve copied and edited the instructions below that another reviewer had posted because it helped me. Also see the images on the product page in the details from the manufacturer. These will also help.Instructions: Start by adjusting the chair to the ideal height & mark this place with a permanent marker. Install blue rubber gaskets to the metal plates in the middle of the plates where it will be gripping the pole your seat sits on. Then fit the 2 plates around the pole at the lowest point on the pole that the chair sits on, and start screwing both sides in, with the provided screws. Use a hexagonal wrench (one is provided) to twist the screws vigorously until they are as tight as possible, try to sit and fine-tune it (I didn’t feel the need to do this because I wanted it as high as it goes). It takes about 5 minutes but once done your chair will no longer drop down. The screws only grab onto one side so if they aren’t grabbing, put them in the holes in the opposite direction.I’m not sure why the red gasket is here and that there is only one but in the pics provided by the manufacturer has one installed on one side so that is what I did. I have no idea what its purpose is but I figured, why not.By the way, the clamps bend around the chair pole as you tighten the bolts so even if it seems like your pole may be too thick to secure it properly, when you tighten it, it will fully grip, from my experience at least.

Simple fix for a sinking chair. I liked how easy it was to install. However mine eventually failed after about 5 months. The silicone that holds the piston in place failed so the chair started sinking again. I would recommend though as it is much easier than swapping a piston out.

My office chair developed a problem where I would be sitting it in, and suddenly start sinking. Lots of fun on video calls, I would just sink down off the screen, followed by that slightly awkward jump to try to get the seat back up to where I wanted it. Was starting to be a weekly thing, and I was sure I was not hitting the release. So in an effort to extend the useful life of my chair, I got this. Laid the chair on the side, and took under 5 minutes to install. It is just a thing that grips the tube that holds up the chair to prevent it from going down. Since I wanted my chair at the "top height" it was easy to put in that position and install, but if you preferred a lower height, it should work wherever you set it.The only thing to realize is that once installed you can no longer adjust the height of your seat (perhaps, if you adjust it lower, you could still make it go up and it would only go down a bit). The seat still spins around find, reclines, does everything it is supposed to do, just no longer falls down on its own.

This product did not work. Was tightened twice and continues to slide down.
