Thought this one would be a no-brainer, but well, here I am bitching about it. Have an aeron chair and need to replace the gas cylinder. I’m going in armed with a tutorial video, a Pipe Wrench, a 2 lb hammer, some towels, and the official Aeron_Chairs_Disassembly_Instructions_p3.

I’ve read that it “isn’t as easy at it looks” and “you really need to hammer on it”, but I wasn’t prepared for what was needed.

Lets take a moment to look at these instructions for changing out a part on this $1200 chair. The fact that a hammer is required made me nervous from the start. But just go into step 1 with the understanding that you are gonna fuck up that old gas cyclinder. You are gonna fuck it up good.


Yep. Just bang on that fucker. The center section of the gas cylinder peeled out of its black metal case and shot inward, freeing the base. Outer sheath with dented metal edges:


Inner gas cylinder still attached to chair. Its cool though – I’m pretty emboldened by my hammer skillz – maybe these instructions know what the fuck they are talking about.

Ok, Now Im uncomfortable again. How the hell is striking the base of the chair with a hammer going to free the cylinder? Plus, I dont really want to be hammering away on that plastic. So lets review just the first few seconds of our tutorial video again.

looks easy enough right? He just flips the chair, and twists it  CW with a pipe wrench. I can do that.


Nope. I twist on this damn thing so hard my pipe wrench breaks.


For the life of me I cannot get this off. I’m not done yet, but Round 1 is a draw. I got the base off, but seriously vexed by the gas cylinder. -10 points for scuffing the hell out of the side of the chair when I put it on the concrete with out putting down cardboard first.
