  • Worked for me on my early 2000's Herman Miller Aeron chair
Bought this to replace the cylinder in my over 20 year old 2004-era Herman Miller Aeron chair. I watched a few Youtube videos to learn tips and techniques on replacing the cylinder--it was a real struggle to separate the old cylinder from the chair. Easily took me over an hour hammering away and struggling with the pipe wrench, but I finally removed it. I have some pictures comparing the original cylinder and this replacement. The original part is a bit longer, and it fit in the wheel base a tad deeper, but everything seems to be ok. I've been using the chair for about a month since replacement and all seems fine! Adjusting up/down all seems perfect after minor adjustments of the set screw. ... show more

  • Fit my 2002 Herman Miller Aeron

  • Perfect Fit Aeron Classic 2011
I actually converted a HM Stool 2011 into a Aeron Classic using this and it was an actual perfect fit. Just know that the bottom part lays about 1cm from the floor. Recomended!

  • Back in the saddle again..........
Replaced cylinder in my 17 YO Aeron and it is like new. The seat was rising and my position was off so that I was sliding forward and killing my back. This one is really heavy duty and 100% made for the aeron, glad I went for the extra bucks. Delivery was faster than advertised and YouTube paved the way once again. ... show more

  • Perfect fit for Aeron
Perfect fit for Aeron with puch button piston. Original piston and this replacement were both SHS 1B08VM B/C. I forgot to get a pic side by side but here it is installed. Next day delivery was a life saver.
