How To Remove Arms | Herman Miller Aeron Chair 

Thank you very much friend, long live the internet, in a studio I have the model with a wheel and it was really easy to remove the armrests, but at home I bought a model like yours and yesterday I spent a horrible afternoon trying to remove it, thanks once again

Take the back off with an allen 3/16. The inner two bolts are torx T27. The one on the right is a regular thread, so right tight, left loose. The one on the left is a REVERSE thread, so right loose, left tight. That was the cause of all my problems - not realizing that the bolt on the left side was a reverse thread

I used a heat gun to melt the plastic lever, just twisted the whole thing right off :) In case anyone prefers to avoid impact on their wrists or something idk

Thank you so much this saved me so much time and pain from these ridiculously over engineered arms! Took all of 60 seconds with a reciprocating saw but it could have turned out badly too haha

DAWG. I haaaaaaaaate these chairs. Thank you for making this video so I know I'm not alone in ARM HELL

I am watching this video after giving up trying to get the bolt off with hand tools, and I then switched to an impact driver instead of putting the drill in reverse I put it in forward and it manages to break the bolt in half so if you too lazy like me you use a hand saw just use an impact. You could also just drill through the bolt.

As a fellow composer who's been trying to take off my armrests on the same chair for the past 30 mins (all while procrastinating on a cue lol), THANK YOU for making this video!! Now I know I can give up and perhaps try your sawing method on another day. The endlessly turning torx screws were driving me crazy... Any regrets since you removed yours?

Don't need to cut it off!!! Torch the plastics lever to melt it off. Then heat up the metal nut. Use a piler to hold the nut and turn the bolt with T27. On left hand side it is a reversed thread so turn right to loose it.

This is so crazy all you need to do is have someone pull on the arm while you turn the screw and the threadlocker that holds it will come apart.

Just had same issue on my 2015 Aeron, read that the previous thumb roll adjusters didn't have loctite and the remastered neither so they can be tightened easily. What a nightmare, I want to keep my arms but what a daft mistake on Herman Millers engineering team. I'm toying with the idea of cutting them off and replacing with the thumb adjuster arms because that is the only long term solution...for now i'm just using cardboard stuffed in to keep them tight, shouldn't have be cutting off and replacing the arms ffs

Not looking to destroy my chair. Still a useful video as people in the comments seem to have figured it out

There's an easier and faster method. Use an oscillating multi-tool with a metal-cutting blade. Loosen the arm lock handle, pry the washers away from the underside of the bolt head, wedge the blade into the gap, and saw away. Takes about a minute to cut through those bolts.

haha chuckled when i got to the end of the video and saw the keyboard on a pullout tray and ua apollo rack interface bc i literally have the exact same setup (only with a universal audio 6176 mounted under my apollo instead of an avalon lol) and realized.. yep this guy is frustrated with trying to play/track guitars with armrests in his way too 😆

I made a video showing an easier way: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-S8-YkscTjTo.html TLDR: the LEFT arm rest is reverse threaded, so clockwise to loosen AND it helps to wedge something in the side to keep if from turning endlessly. Video isn't shot very well but it shows all of that and some other tips!

"this method is..." *cut to shot of handsaw in chair* "destructive..."

If you left the lever on could you not have just unscrewed the T27 torx bolt and taken the arm off that way without the destruction.
