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

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.

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.

Recently brought a chair and found that it sinks from time to time but it has been happening more lately. This was simple to clip on and has stopped this frustrating issue. Whilst I'm grateful it exists, it is a little pricey for what it is. You can clearly seen it has been 3D printed cheaply as the texture of plastic is rough and flakes of filament kept falling off. Had it not been for covid, I would have been able to 3D print this much cheaper from work.

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.

It gets the job done. You can customise roughly the perfect spot for yourself to stop the chair sinking and finally the chair you once bought is now great again. I don't know what else there is to say, although, I did order this product once for myself and another as a gift for someone and the designs as well as pieces were different, the gifted one even had an extra piece I never got but regardless of that, in both cases, they did the work that was needed to be done. My 4/5 comfort rating is purely down to the suspension. No more smoothly and comfortably sitting down. However, you spend more time sitting rather than in the action of sitting down and I would rather hours of high sitting than slowly sinking. Not only that, I'm pretty sure you can re-use them, if that is the case, that is a nice little bonus for getting this already useful product.

While cheap and sufficient for a temporary fix, the plastic itself is brittle as all hell (as all layered 3d-printed shapes are under stress) and *will* shatter after a few days. Unless you want to buy a few at once, invest in either a pack of hose clamps or or cable-ties sufficient enough to tightly surround every inch of the block, and cover the whole ensemble in two-part epoxy adhesive. It's still cheaper than buying a new chair, and while I'd prefer it to be a solid chunk of hard plastic it's still perfectly adequate for the task. The three stars is for the fact that I have to purchase extra stuff to make up for the product's shortfalls.

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!
