Robust enough
Satisfied with it so far.

This is a good cylinder and I love the height it adds. I viewed the installation instructions and watched some videos, but I did not have an easy time installing it because my chair was old, grimey and dusty. (The label on bottom said 2003) Tips if your chair is old like mine. 1. To get the existing cylinder out of the chair, you may need to whack it HARD. I used a 5lb sledge and a block of 2x4. Even then, it took SEVERAL hard whacks, putting all sorts of dents in the wood block. 2. Use an adjustable pipe wrench to unscrew the cylinder. The teeth on mine were leaving marks on old cylinder and it wouldn't budge. I eventually applied WD-40 at the top and that loosened it up enough to come off. There was a bunch of rust inside. 3. Once you install the new cylinder, you will have to pop off the plastic cover under the chair and adjust the set screw so it doesn't sag. After I did this, it worked perfectly.

Installed this in a Herman-Miller Aeron that I've had for years. As a 6'4" man, no office chair is tall enough for me by default and crooking my legs under the chair was starting to cause me some muscle issues. This was relatively easy to install (though you need an 18" pipe wrench and a solid mallet) and it doesn't look like adding only a few inches to the travel will help much, but it has made ALL the difference for me. 100% worth it.

Delivered as promised, easy to install and worked exactly as described and planned. Used on my draftsman chair to replace the as purchased original from nearly 4 years ago.
