Fix A Sinking Office Chair - No Gas Lift Cylinder or Tools Required - Replacement Office Chair Gas Lift Cylinder Alternative - Dropper Stopper

OMG a life changer ! SO easy to fit and does the job perfectly , my chair is fit for purpose again and no need to send to land fill . It took approx 3 seconds for me a 62 year old to fit it . Would highly recommend

I have a great office chair but it is now 6+ years old and recently I noticed that it was gradually going down while sitting on it, meaning I had to constantly readjust it upwards. So, I thought I would have to either spend £100+ for a new chair, or faff around trying to find the correct replacement gas cylinder. Knowing me, I'd probably choose the wrong one and have to re-order, etc. Thankfully, while searching I found this item by accident and thought that for less than £10 I should give it a go. Arrived within 2 days and I can honestly say it is a godsend. Easy to clamp on to the gas cylinder/chair adjuster, and so far seems to be perfect for the job. I saw some reviews that said it is flimsy, but it seems a solid piece of kit to me. Once fitted to the chair, the chair no longer goes up or down, of course, but as the highest position worked for me, I am very happy to have this on the chair and save me time and money investing in a new chair! To be honest, even if it failed in a year's time (which I don't expect it to), I'd rather spend another £8.95 on one of these, than buy a new chair anyway! Very few "wonder" items like this, actually do what they say they will, but I am very confident this will keep going for a while, so thanks!

I sit on my executive chair for almost 4 hours a day each week and instead of getting a new piston (as I don't need to raise or lower my chair) I wanted something cheaper to install instead. This was an essential buy for me but alas after only 16 days of usage it broke into pieces, my chair went flying downwards and I along with it. I'm not a huge guy, I've got mass sure but its not like I'd break it by just sitting down, plus the chair may be a bit heavy but it weighs no more than a small chair would. I heard a crack about a week in when I sat down and it must have gotten worse from then on. The zip-tie included is abysmally small and weak, if you do intend on using this on a chair get some of the industrial sized zip-ties to secure it. Its great for wasting £8+ on, that's about it really.

This device certainly does what it says "on the tin". It restored my swivel chair to a renewed state of usefulness. It takes less that 5 minutes to install and the result is instantaneous. The downside is when you sit on the seat it goes down with a bump and does not have the "cushioney" effect you get with a gas fitting. However I am very pleased with the product. Delivery was fine and can recommend it to anyone subject to the caveat about the solid feeling when you sit down.

I was given a mesh chair from work for my home office, which had only been used for a month (although 3 years ago) as the back rest was too stiff for the user and the seat had started to sink. When I got it home and tried it out at my desk, I realised it had completely sunk and was far too low to use, so I decided to use my existing home office chair. Two weeks later, the seat on this chair started to sink too. After looking for a replacement gas lift piston, I was unsure whether this would be money well spent (would it fit properly? would it work?) so I decided to look for a new office chair and had placed one in my Amazon shopping basket, whilst continuing to shop when I stumbled across the Dropper Stopper. I thought it was worth trying, so I ordered one. It was delivered the next day (which is today). It was easy to install as you just clip it around the gas lift piston as per the instructions (make sure you wipe any oil off the piston before you start) and feels fairly robust. My old chair is now back up to full seat height, but this is now in a fixed position (as the height can't be adjusted with the Drop Stopper fitted). However, I was so impressed that I immediately ordered another one for the other chair! Many thanks - you have saved me the expense of buying a new chair, plus I will now have a choice of 2 chairs!! Happy and pleased to recommend.

It’s a cheaply made 3D printed part. If I’d have realised I’d have made my own. Sadly being 3D printed - the layers can delaminate from each other in some situations - something which happened to me. Similarly the clip very quickly wears down and can eventually open when under any kind of weight, so you need to secure the parts to help avoid them unexpectedly popping off. Thankfully it was only a short term fix while I waited for warranty parts to be shipped. Honestly I’d have paid maybe a fiver for this. Since it’s likely only a quids worth of filament tops plus design time and electricity. Or alternatively I’d have just have found a free or cheap STL on Thingiverse or similar. Could be wrong. But I think this was made with PLA rather than ABS - it would certainly explain the issues I had with the part weakening over time.

Have a very expensive ergonomic chair which I bought second hand (still costly even then but the retail price would make any of us actually weep) and after 6 Years of daily use it’s had a little drop vs a complete fail -!clearly the start of end of life for the lift. Delighted to find this little fix and it works brilliantly. Had found a DIY guide using plumbing parts but this is low cost and keeps my lovely chair at just the right height. 10 years plus of use here we come! Highly recommended. I think probably most effective when you first notice that sinking feeling vs a complete collapse but excellent at the job. Great to repair an investment like a really good chair - better for the environment as well as better for the wallet.

Not a permanent Solution, fixed it until i got around to just replacing the chairs piston. item appears 3d printed (not well printed) after a months use the plastic starts to flake away from chair preasure on it. If you want a quick easy but expensive solution go for it otherwise just take the lunge and buy new piston to replace How i replaced stuck piston: Items needed, WD40, Wrench, New chair piston. Apply WD40 to top of piston connecting to the chair as well as to wheel base make sure to apply to both sides. once you have left for a couple of minutes make sure chair is laying down and clamp wrench tightly and twist wrench with a lot of force to remove both sections from the chair. Once removed place in new piston, job done.
