great instructions, after buying a new gaming chair that is far too low, and ordered a new gas lift this was great instructions

Hope the following tip is useful to others: Long story short, if the pipe wrench is not budging the old gas piston, get a blow dryer or a heat gun (basically the macho tool version of a blow dryer) and point it as the base of the gas piston (i.e. where it enters the seat) for a good 10-20 minutes. I'm in the middle of doing a gas piston replace on a second chair, and I had hoped it would be easier than the first, but it looks like I'm going to have to pull out the blow dryer again. As other commenters have said, I tried all the obvious tricks. My pipe wrench actually cut GROOVES in the metal of the old gas piston. The blow dryer worked. I'm still not sure why. Obviously metal expands when it heats up, maybe some combination of that expansion breaking the seal, or just forcing the hole to widen, or the heat softening the plastic sleeve it slots into. Any way you slice it, it worked.

Thanks, you saved me time from trying to figure it out.

I tried other instructions on how to separate the wheelbase and the cylinder, but it wouldn't budge. I found your video and your tip about popping the clip on the bottom of the cylinder was the missing piece of the puzzle for my Dormeo Bristol Octaspring chair. I followed the same steps on the new cylinder and was finally able to successfully remove the old one and install the new one. Thanks so much!

Many Thanks for the clear instructions without any beating about the bush - greatly appreciated.

This is the exact chair I needed to do this on lol. Amazon returns should forward this video to people and pay you for it.

Thank you so much. What an extremely helpful video. It worked just as in your demostration. Life saver!!

I bought a chair from amazon and couldn't separate it to fix it and your video helped a lot. We also used a little bit of oil inside and it worked perfectly. Thank you for the amazing video.

You know how long i have been waiting to find a video that explains this to me ..........your a star thankyou.

Thank you for the video and explanation. This helped a lot.

Thank you😭😭😭 The wheelbase removal part saved me😭😭😭

This helped my put the hydraulic cylinder back in place! Thanks a ton!

I’m lost you deserved a subbed thankyou!

This was just what I was after! Thank you!

Thank you so much! Had to send a chair back after putting it together and the base wouldn’t fit back in the box but I couldn’t get it apart!

thanks for the video. i was having a hard time to remove and replace the cylinder ffs but thank you again.

Nice, it worked! Thanks a ton!😆

You are a LIFE SAVER!!! ❤❤❤

would a rubber mallet work instead of a hammer?

No matter what I did hitting it or trying to get a wrench to do it the gas cylinder would not budge whatsoever but thank you the video was helpful for everything else though

You saved me! You're amazing 😊Thank you very much 🎉

Well done.

thanks, helped a lot

you saved my life

you saved me big time

THANK YOU

By heat do you mean from a hair dryer?

I LOV U THANK U

Do I need the orenge thing

Nice Like :D

Ooo ooooo oooOmagadd

What's the size of the cylinder please.

Thank you

LOL, you destroyed the chair, so many needless steps

this is so wrong in so many levels, you do not hammer the gas lift and you do not need to remove that clip, there are no serviceable parts in it. use a rubber mallet to hammer the base of the chair while holding the gas lift to remove it.
