Thank you for the video. Is there one standard size for the replacement cylinder and if not, how should I measure the original for replacement?

Why not just leave the collar installed??? looks better than the other 2 methods

I wrapped my PVC pipe with black duct tape. Not quite as ugly

I'm here after a week-long tension headache. I was troubleshooting/measuring everything else, from blood pressure to blood sugar and diet, sleep position, etc, everything was fine. Turns out it might be leaning in and staring at the computer wrong for 16 hours a day (work from home + gaming). Thanks for this!

Excellent info and your video format is perfect. Thank you. Ordered a replacement

you can cut the plastic tube in half or one side if is flexible enough and just put it around of the bar instead of taking chair apart, then you can just wrap it with tape or something and it will also hides the tube if you use some paper or coloured tape...

Absolutely brilliant, the PVC pipe worked a treat, and we repaired 3 chairs, thank you.

Hi, is it possible to get just the cylinder removal tool and not the cylinder on your Amazon store ? The cylinder supplied with the kit has a 4.75" lift - I need a cylinder with more lift, close to 6.0" or more of lift. I can get the higher lift cylinders elsewhere, but like the idea of your cylinder removal kit. Looking at the removal tool, why need the first collar at all ? Can't the tool consist of just the second one with the screws and have them push against the base directly ? If you're worried about the screws marring the base, we can just use bits of metal (like flat washers) between the screws and the base.

I replaced the hydraulic cylinder but again within one day it started the sinking.😢

Thank you! So helpful. I didn’t know I could pull them off until I watched this

thanks for your tips although i just used ALOT of duct tape

Good luck doing this with a classic pre-2000 model with rust inside the friction fit.

eh bro u look like a high elf dye hair blonde and grow out hair 👍

I didn't buy this kit but it looks amazing. I have a Branch Ergonomic chair and the cylinder went out after 2 years. Branch sent me a replacement and a dumb video on how to replace it. I was not able to separate the last part (Cylinder and base with wheels) until this video gave me the confidence to just hit it with a hammer. I had been trying for 2 days with a mallet, and this morning I bathed the cylinder in WD-40 and finally hit it with the hammer. It probably took 8 hits with the hammer and the cylinder came loose. So happy I watched this video. Thank you!

Damn - this dude is a beef cake

Method 4: buy a new chair.

Your intro alone was so helpful. You absolute rock-star. You amazing wunderkin.

Thank you .

Or you could buy a pipe wrench.

You're a god for essentially provided a super simple and sufficient version first, without crazy long intros or ads.

Problem solved. Thank you so much!

DOZYANT vs office owl Office Chair Gas Lift Cylinder? Which one is the best?

Excellent video, and that tool looks very useful. I haven't used it, but I wish I had. The first chair I fixed, it was a huge pain to get the cylinder out of the bracket. The second chair, I ended up ruining the chair and had to replace the entire bottom half (bracket, gas cylinder, base and casters). For the first chair, after much attempting to use brute force and a large plumber's wrench, I asked a machinist friend and at his suggestion I heated the cylinder with a blow dryer for 20 minutes, right where the cylinder enters the chair bracket. That loosened things enough for me to pull the cylinder out with the plumber's wrench. For the second chair, I don't know why but it was flat out impossible. I took the chair over to my machinist friend's shop, we unbolted the bracket from the bottom of the chair, put the cylinder part in a vise and tried to use a half inch steel rod through the bracket. Ended up bending the rod into an L shape. Tried vise grips on the cylinder, ended up cutting grooves in the cylinder. I ended up throwing bracket, cylinder and chair base away and ordered a replacement. Also, you're the only video out of five I've looked at so far, to talk about the plastic cap, which also was not mentioned in any instructions that came with the replacement parts!

Hi Kevin, Good afternoon, I just came back from my Home Depot down here in Bogota/Colombia, where I got 1 16-36 mm hose clamp copper color and a white PVC pipe 1m long by 2 inch Ø. I asked the seller to cut a piece 12 cm long. Following your great and easy to follow instructions, and as I am myself quite stubborn, I decided to go on the PVC (the hose clamp seemed too easy.☺☺) I disassembled the base placed the 12 cm and every part in place and…… obviously I messed up with the 12 cm and had to redo every step (measure twice and cut once!!) therefore I cut another piece, this time 12.5 cm et voilà job done!!! I total I spent +/- US$ 4 (clamp 1 - 1m PVC 3). Tomorrow, I will paint it black, it will look as original hahaha ☺☺. Again 1000000000 thanks.

AMAZING i DID EXCATLY YOUR FIRST DIY CLAMP AND DUCT TAPE ( Thank you so much " I was really upset with my Sinking Chair " )

That's a great video!! THANK YOU!! What's the size of the hose clamp you used, please? Also, what is the Ø of the PVC spacer please? Thank you.

Please explain why the wheels need to be removed. Seems like it's an unnecessary step to me. Nice wheels...do they have skateboard wheel sealed bearings? Didn't know you invented them. Kewl. Plus it raises the chair a little...right? Lifetime warranty is awesome. New shock kit is...pricey.

Hi, well my chain was sinking every time I leaned back, and it got really, really aggravating. Like I was fooling with the thing all day, because you are always leaning back, for one reason or another. So I replaced the piston, which solved the problem of a spongy sit, but it still sank upon leaning back. So, one day I seriously studied the problem, and after observing another similar chair, discovered a tab was pressing on an apparently white nylon button, releasing the piston to sink. So, what I did was disassemble the original chair to access the same white nylon button, and using I think, my Dremal with a cut-off wheel, removed like1/16th-1/8th of the top of it, and it seems to have worked. It has been several weeks now, and I was real hesitant to really push back and still am, but a few times I did, and still no sinking. Yet, I still retained the ability to adjust the height of the chair. So try, at your own risk, but this was driving me nuts.

Schedule 80 pvc pipe works better itis heavier/thicker that the schedule 40

what i did was this. removed the masking tape and screwed on 11 hose clamps in total stacked one on top of another. its been 3 weeks and so far, fingers (and toes) crossed, not sinking anymore. still thankful for this vid, else i would hv trashed this chair and forked out a hundred bucks to get another. im overweight too and those 11 hose clamps are strong enough to support my weight

Any word on if there’s a lubricant that chairs use to allow the cylinder to move up and down and rotate inside the column? I have a chair where I gave up trying to remove the cylinder after having removed it from the column and base, but when I put the column back onto it, now there’s too much friction when the chair rotates and is so tight it won’t even rise when in the lowest position.

Just an addition "tip". If when pressing the handle the chair doesn't lift up, try laying the chair flat on the floor and pull the handle - the chair base should extend even with a faulty / less-than-good hydraulic cylinder. There's no need to put your foot on the base and pull, as long as you're okay with extending it all the way up.

I wish that you guys had shown how to handle removal by going side-to-side with a mallet when the cylinder wouldn't come out.

Hello to all my sinking brothers and sisters around the globe and thanks to @theofficeoasis! I needed a quick fix to my sinking chair for few online calls and I had to avoid the awkward sinking on camera asap - the first solution worked perfectly. I didn't have the metal hose clamp - so I used the plastic "cable ties" - i used 5 on the whole width of the duct tape. Works like a charm. No longer sinking, I can keep sailing on my old chair. Happily postponing my new chair purchase to next month(s) :)

If you are using PVC pipe, you can paint it black for a better look. Be sure to sand the pipe first so that the paint will stick to the pipe.

I just installed the new cylinder, but when I sit on the chair it drops to the bottom. Then when I stand up it rises again. Not sure what I could have done wrong…

my problem is not sinking but that something has come loose inside the seat and the arm rest has come loose, how exactly do i fix this? no, the bolts holding the arm rest in place are not loose, something inside of the seat of the chair, holding the arm rest to the rest of the chair has come loose and it looks like if it can be fixed at all, the chair is going to have to be dismantled

The lift is going to be landfill after it is removed, so no need to buy more tools when there's no need to be careful with the unit. Just go to town on it. I used a pipe wrench on a very VERY stubborn lift today and it came off no prob. I would try some WD40 if I needed it which can be an aid when needed. I do support speciality tools if you are someone who do service and maintenance on equipment like this and are going to re-use the lift, but for the average consumer who are just replacing a unit, I will just advice to go to town on it and get it done.

Loved your format on the video. Thanks for not making us sit through the whole video to get the info. Great Video!

nice and helpful! Thank you😊

would the kit fix every chair? how do i know if this is compatible with my chair?

Clear, concise and exactly what I needed. Thank you!

Sink the chair all the way down, then invert the chair 180 degress and rotate the base a few times, let press the lever and let it extend, turn the base a few more times then put the chair right side up again. It lets the oil in cylinder re coat the seal.

this is what i did. wipe the metal part below the chair. then used masking tape (cant find duct) then use tightened the hose clamp to the same location as demonstrated. at first i thought wow. it works. was seated in the chair for ard 10 mins and not sinking. then ard the 11th min down it went. may i ask what i did wrong please? any tips from any1 will be appreciated

Thank you …I didn’t realize you could just pull them off

For today I have put on a hose clamp. I work at a hardware store buying so a pipe is my next option.

Very easy instructions i have bought replacement cylinders from this company befofe and your video is is very helpful
