QOOSIKICC 19 Pcs Fixing a Sinking Office Chair Cylinder Alternatives Gas Lift Tools Kits, Office Chair Saver for Stop Sinking, with Hose Clamps, Dual-Purpose Screwdriver

After reading other reviews I just quite jubious about this product. Im quite a heavy guy and thought that these would break in an instant, but bought them as the price was fair, they came with the screwdriver needed (so I didnt have to go and buy a seperate one) and as stated the reviews were mixed. So I gave them a shot... and im glad I did. They are brilliant! They hold my weight, and Ive had them for over a month and they're still holding strong. They are easy to install, took all of 5 mins.Dont get my wrong they are a bit ugly when they catch your eye from the next desk, so it would have been nice if the tightening strips were black or if they black shaft sleeves were chrome to match. But regardless they do they job intended, I would highly recommend.

Excellent item. Was going to buy another chair until I stumbled across this! Does exactly what it says on the tin. They hold my chair rock steady!

Having bought a used office chair from a local charity shop I quickly discovered that it gradually sank under my greater than average weight. As my desk is also higher than average, this was problem.For under six pounds, this kit seemed worth a try since failure would not hurt the budget. It consists of a set of split black plastic collars held in place by jubilee clips. The collars are split so they can be pushed onto the chair shaft without dismantling the chair. They are then tightened with the jubilee clips, two per collar. A cross-head screwdriver is included with the kit. I needed two collars and the installation took five minutes. My chair doesn't sink now.I have withheld one star. The collars do look flimsy, although they will be working under compression; we'll see if they last and I will update the review if they break. Another point; not sure how many collars should be in the box. There were three in mine and I only needed two but the illustration implies you get more than that. On the other hand there were 12 jubilee clips in two sizes, as illustrated.It does occur to me that this simple fix could be home made but, at the price, hardly worth the effort.

One of the best purchases I did in my life, it worth every penny and my office chairs are like new, so that saves me a lot of money!!! Highly recommend

The hydraulic of my chair kept failing and slowly sinking... so if you had this same issue then this product will do what you need it to, but you're really just covering up the issue with a short term fix. These are easy to install and look sturdy but over time (a few weeks) they'll start to bend, and break and you'll be back with the issue again.They are just bits of plastic after all, and if you use your chair a lot like I do, then you'll soon find have the issue again.Not a bad product, but not a great one either. Fulfils a certain purpose.

The screwdriver is a nice touch. Why I say it's a little tricky to install is that I had to trim down one of the spacers to get a precise fit. Ultimately it works, I'm over 23 stone (330lb/150Kg), and it's holding my weight and no more sinking!

it was either this or throw away my chair 😭I took 2 and sawed the other one in half and it worked great!! I am so happy :D

This product does exactly what it says it will, it was super easy to install on my chair and it has meant that I don't need to pay to replace the gas lift which is great. Nice touch that it comes with a screwdriver too so you don't even have to get the tool kit out to install it. Thanks, great product!
