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.

Five minutes to fit, enough to do my job twice over and free screwdriver. Works ok, see how long it lasts.

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.

Why did you choose this product over others?:Worked perfectly, Just what I needed. Saved me money on buying another chair.

I nearly wrote this off as a bad choice. Still not sure whether these tubes will be strong enough. I had mistakenly thought that the steel clamp ends had to be pushed through by hand. Didn't really understand how it worked.Put them back in the box thinking they were faulty then took them out of the box and tried again. Instructions not really clear. In end worked it out. The steel clamps work like a rachet whereby the screw draws in the end of the steel clamp to tighten around the rubber tube.I hope this does not break as I've read the 1 star comments and a little uncertain this will hold the chair height in place. Only time will tell.

Does what it say on the tin... And better price than the plastic clip ones, I'm heavy and they hold my weight perfectly, with spares and a free screwdriver too, bar has.

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

From believing I'd have to change the gas piston, watching a couple of Youtube videos and not relishing either the price or the work involved, to this. Took about 5 minutes, most of which was actually finding my hacksaw and cutting one of the three plastic tube bits to fit. It's only been a half hour or so, but it seems strong enough to take my 215 pounds okay and stopped the annoying dropping of seat level. That's another of life's little irritations out of way.
