Features

  • Upgraded office chair saver for stop sinking can control the height of the seat, prevent repeated sinking, and can rotate the seat normally after improvement (the old plastic model cannot). Universal size fits most office chairs, within the cylinder diameter of 25-28mm(0.98-1.1 inches). After fixing, the chair can rotate smoothly and prolong the service life of the chair.
  • 304 stainless steel material, strong weighing capacity, not easy to break and more durable than plastic models. With blue rubber leather pads, the friction is greater, and it fits closely with the cylinder to prevent the seat from sinking. Also prevents unsightly marks from damaging the chair.
  • Easy installation. Start by adjusting the chair to the ideal height you want and mark it. Install the metal plate and rubber gasket, and clamp them to the lowest and fix it with screws. Use a hexagonal wrench to twist the screw vigorously and fix it, try to sit and fine-tune it. It takes about 5 minutes but once done your chair will no longer drop down.
  • Come with an office chair sink stop and a hex wrench. Easily solve your chair sinking problem without spending more money on a new chair.
  • We offer worry-free warranty and friendly customer service within 12 months for your confident purchase. If you are not satisfied with any product, please dont hesitate to contact us, we will serve you our best.

    • Works great, if it fits
Size: 1 Pack
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. ... show more

Review Image by Gisela Coronado Gisela Coronado
Only reason this got 4 stars is because there was no manual to put this together but looking at the pictures I was able to eventually get it on the chair without breaking anything. So far it has been on for a couple days on my office chair and has kept me at the height I want to sit at. Before the chair would gradually drop till it can’t and doesn’t help when I want to be leveled with the desk. I did like that it did come with a tool to put it together as I was not sure what tool I would have needed. For sure worth it for the price! ... show more

    • Good concept
Size: 1 Pack
This product is a good concept, but the two small pieces of rubber just can't keep the grip it needs. I fixed this by adding a piece of 1 1/2 inch PVC pipe spit down the middle to snap around the shock and then added the clamp. No more drop ever. Like I said good concept but needed a little more.

Review Image by Robert's reviews Robert's reviews
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. ... show more

This thing has officially worked as intended longer than the hydraulic doodad it's fastened to. Very happy with this purchase.

    • Cheap fix for a sagging office chair
Size: 1 Pack
I thought I was going to have to drop a few hundred on a new office chair since mine kept slowly lowering through the day. This thing took me five minutes to install and no more sinking. I love it.
