### ⭐⭐⭐⭐⭐ Easy to install

Good quality and also Easy to install on my Herman Miller.

### ⭐⭐⭐⭐ No a perfect fit. But good enough.
*by B***N on December 24, 2023*

The clamp tool did not work on my Herman Miller. The piston shaft was too small for the included clamps to work. Also the bottom of the tube sits mich lower and closer to the floor. This would have been a problem except for the fact that I put the roller blad wheels on it and theyvlifter it off the ground plenty.
