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

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.

The device does what I expected - basically it clamps on (in 3 separate 4 cm sections) around the gas strut to prevent it sinking. I have an office chair and (as most likely happens with others after some years of use) the gas strut leaks. I could not work out how to even dismantle the chair to get to the failing part.The device solves my problem but of course it loses the ability to adjust the height frequently (you can choose the height that it supports but it does not restore the function of the lever that allows you to raise or lower the seat).It is expensive for 3 pieces of extruded plastic but, on the other side of the coin, it saves replacing a chair.

It has slipped a little bit but seems to be holding for now but the jury is still out on this item. Three stars for now I will update later if it still holds. Here is update on this item 17/02/2020. alas the whole thing has snapped off and pieces went hither and thither and are no more. Avoid this item it is not fit for purpose, I hate giving bad reviews but I am very disappointed. If you want to fix a sagging chair buy a pack of straight couplings 40mm that's what I did and my chair is now sorted it took me five minutes just remove the swivel base slip the amount of couplings needed replace the base and your good to go. Amazon sell these packs.

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 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!

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.

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.
