Easy to install as replacement for the standard one my chair had. Fit properly and the instructions described the procedure easy enough that most people would understand. Great value for the price.

### ⭐⭐⭐⭐⭐ Fixed the problem!
*by D***J on January 15, 2025*

Old one made a loud pop when I moved around in my chair and was SUPER annoying. It was a $500 chair and this new $20 lift fixed the problem. Easy to remove old one and install new with a pipe wrench and rubber mallet
