How to FIx a Sinking Office Chair | Easy Simple Fast Free Cheap | Modify Faulty Gas Cylinder Lift 

I did the extra work to provide understanding and multiple options (I apologize if I made it look complicated or confusing). All you need is a one dollar pipe nipple of the correct length from the hardware store, and a flat head screwdriver. It literally takes about five minutes to install and complete. Example: www.homedepot.com/p/Southland-3-8-in-x-3-in-Black-Steel-Nipple-582-030HN/100192847 Or if you already own some existing pipe, you can cut something and make it work at no cost!

Dude, that's perfect! I am making this repair myself right away! Thanks!

My wifes chair has been collapsing for at least seven or more years now. I had a 1/2" nipple a little too short. So I added a coupler screwed tight and cut to proper length. Fixed in about 30 minutes. This is about one of the easiest solutions to a problem I have seen on RU-vid yet. Just never though of a so simple fix. Thank a Lot

You are my hero, I have this same chair and am in the same situation, I managed to use some 3/4 pvc pipe cut to length and filed down the plastic washer to fit inside the pipe like you showed and the chair is so firm and sturdy again, I have been dealing with this chair sinking for months now and finally have sweet sweet relief, thank you very much

I love you. No joke. i have been sitting on the same exact chair for the past 9 months without a proper fix and no money to buy a new one. I am 2meters and 2 cm's tall, and my chair wont raise anymore. Needless to say my backpain has been terrible and unbearable. So thank you, for the extra effort you put into this video. You have saved the spine of a 24 year old

AMAZING VIDEO... precise, clearly spoken, to the point, with options available, and a conclusion. What more can a person ask for, really not much. Thanks 🙏 I am ready to fix my chair.

This worked great for me. Thanks for being so clear and not wasting a lot of time at the start with irrelevancies.

I like how you said this isn't a cylinder replacement video but it actually gave me the knowledge to change out a brat of a cylinder that wouldn't just pop out of the base with a few rubber mallet strikes. Thank you!

I bought a high end chair from a second hand store for $15 but the problem was as indicated in this video, it didn't go up or down. I solved the problem using the exact process outlined here. Amazing, and thank you.

Thanks so much for this. Like you, I prefer my chair all the way up. Not only did you save me the cost of a replacement gas cylinder, but while adding the pipe nipple I discovered why my chair was a bit wobbly. One of the washers inside was disintegrating. So that got fixed as well. Thanks again!

This was an Awesome fix!!! It was exactly what I was looking for! Easy to follow directions and the multiple options and diagram really helped. Thank you and keep up the good work! I'm subscribed and alerted 😁

This is perfect! Took me 7 minutes to fix my chair as you suggested including time to find some old pipe in the basement and cut it to size. I also saw other videos about replacing the whole gas cylinder which costs around $23 for a replacement on Amazon. I'll keep that in mind if I decide I miss the chair being adjustable.

Thank you! I fixed mine in a few minutes. I didn't have any of the tools and materials in the video, and thank God I had the idea to improvise with the hollow rubber part that comes with sewing threads. Sitting comfortably on it while I type this. Mucho thanks!!!

This has been the best chair fix I’ve seen, I had all this stuff laying around my apartment ☺️ thanks again

Thank you so much, no more sudden sinking jump scares, it took me less than 5 minutes to apply your fix. nearly tossed my chair for this exact problem. you're a life saver (and money) ♥

This fix was awesome. Saved me many bucks in some minutes. Very well explained and alternatives suggested in the video. Have your like and comment good sir!

Hey, you’re the best. I was going to throw my chair away but then I saw your video. I found some spare heavy duty plastic spacers (from washing machine for shipping). Drilled them out so the piston would fit. Reinstalled the parts and my chair is comfortable again. Thanks

Mate you are an absolute champion! 5 minutes and an angle grinder on a piece of junk spring I had in the garage and my back, neck and wallet thanks you. Cheers from down under!

Conveniently the hydraulic lifts on the GTRacing website were sold out(I wonder why) so I stumbled upon this video and I'm really glad that I did! This was actually super easy and takes two minutes to do. Head over to lowes and head over to the plumbing section to find the pvc piping. You can find skinny 2' pipes for about 3 bucks and they'll even cut it down to the size you need in store. I also picked up about four half inch 'coupling' pieces. I ended up using 3 coupling pieces instead of the pipe because I forgot to account for the length of the bushings, so the pipe was about a half inch too long and I couldnt use it! Still worked perfectly fine with the coupling pieces and ended up saving myself 30 bucks THANK YOU!!!

Vielen Dank ! Das war der einfachste und beste Tipp im Netz . Ich habe einen zum Simmering passenden Rohrsteckschlüssel auf ideale Länge gekürzt ,eine passende Mutter in den Kopf als Distanzhalter gesteckt und fertig war der Stuhl !

I just finished making this repair to my chair. Works great! Thanks!!

I recently got an office chair for free and it was a little beat up and the gas cylinder was busted so it sank constantly. I found this video and I got it fixed in under 10 minutes! Very useful thanks for the help!

THANK YOU! The wife's work at home chair broke and this simple fix made her (and thereby my) day much better!

I just used this method on my desk chair and am very happy with the results! Thank you for taking the time to make this video!

Thanks so much for this excellent solution! Did not have to spend a single buck on making sure my old chair stays up in it's highest posistion! You deserve all the thumbs up one can give!

Best video of this Topic so far on the WEB, thank you buddy you Rock!

Wow! exactly what I needed! and your instructions were very clear, thank you so much for providing alternative fixes and taking the time to test them!!

Perfect! My chair is fixed now - very much appreciate this vid!

Thanks for the great video! My gaming chair has recently started to sink, but only sometimes and only to a height that makes it slightly irritating to sit in. I tried to fix it by putting a hose clamp on the upper part of the cylinder at the desired height, but the clamp either moved under weight or broke when I tried to tighten it. I never thought about using a pipe inside the cylinder itself. It's a rather ingenious solution to an irritating problem, in my opinion. I removed the lower cylinder as you showed in the video (it was easier than I expected), took some measurements, and went to the garage. I quickly found a pipe of the right width and cut it to the correct length. With just some electrical tape on the thin cylinder to keep it centered, the chair is like new again. I can't lower it, but since the maximum height is perfect for me, it doesn't really matter. Thanks again for the great video!

Thank you! I found a chair that someone threw out and I fixed it with pvc lying around. Really simple instructions to follow and it was fixed in minutes.

Brilliantly simple solution!

I have the exact same chair, and my piston/cylinder failed within 2 months! Thank you so much for passing along your wisdom!

Worked like a charm. I fixed my chair with a $3 pipe nipple from HD. You saved me a lot of money. Many thanks.

Thanks a lot, this was great tutorial, really easy to follow! I would also like to recommend screw-nuts as option. I used about 15 screw nuts, since I didnt have tools to cut pipes, and it works perfectly!

OMG! You BLOODY LIFESAVER!! lol. My good chair (about 5-6 years old) blew out a 2nd time about 9-10 months ago (I actually bought a new gas cylinder the first time) and fortunately my building manager gave me a 2nd hand chair for nothing, so I just threw out the old one. Anyway, 6 months later and the cheap version he gave me developed a faulty cylinder (i'm cursed lol). It's xmas coming up and I didn't want to shell out on a new chair, and this chair is too cheap to bother with a new cylinder, so I've just been putting up with it. Today it slipped down about 10 times in an hour (more than usual) so I thought I'd RU-vid search a DYI fix. And BAM!! Saw your vid! I fortunately had some left over 2.5cm pipe from a project a while back, used my Bunnings Pipe cutter to cut to the correct length (following your awesome instructions) and WHAMMO! Problem solved! Like you I NEVER use the up/down gas lift anyway (unless it's fixing it when it sinks down) so this is perfect! THANK YOU SO MUCH, You just made my day! Actually more like YEAR! haha. GOD BLESS DIY HOW-TO VIDS!! haha. Merry Xmas and Happy HYE to you and yours!

I like how you messed with several options. Most guys would have done it one way and sold it as the only way ... this gives me several ideas. Sweet. Good, direct, narration - thanks for scripting the narration and sticking to it. short and sweet. nicely done. JR

Worked perfect! Thank you for posting!

of all the video i watch about changing gaslift chair, this video helps me out! thanks

Brilliant - many thanks!

Right on. I didn't have that brand of chair but the part that needs fixing was the same. I just found the metal tube from an old fan base by the dumpster. It was only an 1/8 bigger than the washers, so I called it good. Done. Thanks :)

I just fixed my chair just like you said to do & it worked perfectly .Thanks

I didn't have some of the extra things you mentioned, however we were able to DIY that part and my chair now fits firmer underneath me thank you very much

Very detailed and thorough, thank you!

It worked like a dream. Thanks for such a simple way of demonstrating the fix.

Easy fix! Thank you for this.

Thank you so much! THat was a clean tutorial, and glad that it worked. I fixed my chair without spending a penny. THanks to How-To & Reviews

Great fix Great video. My barstools kept sliding down especially with overweight people. Watched your video and fixed my 4 stools. I used 3/4 EMT with a steel washer on either end. Cut them just a just about a 1/4 inch shorter so the piston still works a little. Works great!

Thank you! Very easy and helpful :)

Great video! You gave us lots of options on how to fix the chair!

Great video! Just got a new chair online and the gas lift was busted. They wanted me to pay for postage to get it fixed, but thanks to this video i fixed my chair for free :)

Thank you for the video. Fixed my chair!! No more going down and up.

I'm very grateful for your advice, you helped me to save a bunch of money because I had 2 chairs with the same problem. Thanks a lot.

This is a very well constructed video.

You saved me from losing money buying another chair, and also enjoyed working on repairing my chair. Thank you so much 🤍

Super helpful. I loved it and the fix was so easy. Thank you.

Thanks alot bud. I would have never thought of that

easy and straight forward! thank you

Great video, i'm sitting in a randomly sinking chair as I type this. I was fully ready to buy a new one. Now i'm heading to the hardware store for a HUGE savings vs buying new. Thank you!

Great video and saved me from having to get a new cylinder or chair. I 3D printed a tube made to measure and it works great.

worked a charm! $3 fix :) Thank you.

Awesome !!!!! After 2 year still very useful. Fixed my chair in no time. Thank you.

Thank you brother! I made this with my chair and now it's perfect. Thank you!

Thank you ! Great explanation and how to .

You, my man, are a life-saver thank you

This was perfect, made a big difference! Probably get another 4-5 years out of this chair now (:

Thank you for this!!! Super simple solution. Took me 5 mins to fix!!

Wow glad I found this. Exact same chair. Same problem. Thanks

Thanks for the info this helped a lot. I just found some pvc in my garage and cut it to the right size, added some electric tape to fit it and it was perfect.

Excelent!!!!!! arreglé mi propia silla en menos de 15 min con los materiales adecuados. Muchas gracias.

This was really helpful! Thank you!

Thank you so much for your detailed tutorial. My chair is now fixed. 🌟

Man I really enjoyed watching your video, you gave me a solution for my problem (however I dont think I will do anything about it because I'm lazy lol) but mostly I like how you narrated it, great video bro!

Great video, even overly helpful with the calipers. I broke mine out just to hasten the process 1.25 pvc cut to fit DONE. Thanks for this simple solution. saved me several hundred dollars on a new chair at least for a few years.

Hey man I just fixed my chair in less than an hour. Thanks for the tips, much love.

Excellent work

Great fix given most people have a height they prefer and adjustment every time due to a leak is a pain in the arse! well done!

man... YOU'RE A BEAST, THANK YOU SO MUCH, MUCH LOVE

You saved my life :) Really helped me.. took me about 5min. followed your instructions and now I sit up high again..

Great job. This is helpful to fix my chair.

Best video, i saw on the topic. Thanks.

wow, an actually helpful video. short and concise Thanks.

I didn't have the same tools as you, so I just cut strips from a black tshirt and wrapped them such that the chair couldn't go down more than I needed it. Thanks for the general idea!

Thanks!

thanks a lot buddy, I will do as you

Thanks dude. Never thought I'd be looking up something like this... great video!

Thanks a lot, Finally fixed my chair

Thank you 🌸 it's amazing i fixed my chair in minutes.

I did it, and it worked great!

I just fix my chair right now, thank you so much for this video sir.

Thank you so much for this tutorial! 😁 I was losing my mind with my chair randomly sinking. Found a pipe lying around the house and cut it down with a hand saw. Easy peasy!

THANK YOU you just saved me money and i love you

Just fixed my chair with a piece of pipe i got for like 1 dollar at a 2nd hand store. Chopped it to length with hack saw and about 40 min later this chair is better than ever. Thanks!

Best solution ! Finally I can use my chair comfortably...

Thanks Man ! Solved my issue

Thanks so much for this video dude, it worked a treat!

Thank you for the video. i 3d printed the tube i needed. it was 1,1cm x 2,4cm diameter and 9.8 cm long. it was a hour long print and it works great.

All the same parts present on my chair. PVC worked perfectly. Good video. Thank you.

great idea man, found some pipe connectors at the metal tubing department and worked perfectly , thanks alot!
