New OEM Herman miller classic Aeron chair Pneumatic Cylinder Part with cable knob and clip. This replaced the pin top cylinder and replaced it with the most recent cylinder and comes with the clip, knob and cable to remove the old one. This is an OEM Herman Miller part for the classic aeron.

Brand New, OEM Replacement Cylinder for a Herman Miller Classic Chair. This is the SIDE ACTIVATED Cylinder, rather than the Top activated. It comes with the replacement cable, lever, and clip, everything you’ll need to perform the replacement. Take a look under the cover of your chair (it pops off easily with no tools and a couple good whacks in the front of the plastic “sandwich” above the cylinder/below the seat) and ensure this is the version you need, it is the newer and updated version to my understanding. I had a top activated cylinder and bought this by mistake.
