    Works great
  

*by J***N on Reviewed in the United States on February 25, 2024*

Takes a bit to get old one off but this fit right in and it can go up pretty high, so be sure that’s what you want.

    Instant Drafting Chair!
  

*by U***M on Reviewed in the United States on January 19, 2024*

Perfect and tall!  Wow!  Haha!!!  This is exactly what I needed.  I needed a drafting chair, but loved my old Serta, and didn't want to part from it.  So, why not?  This turned my old comfy chair into a tall comfy chair.Installation was super easy.  Taking out the old piston wasn't that difficult, either.  (There's plenty of instruction videos out there.  A pipe wrench came in handy for disassembly.)

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Sturdy and Functional
  

*by M***O on Reviewed in the United States on June 14, 2022*

Used this to heighten my office chair to coincide with my adjustable desk. I thought I needed a much higher cylinder. Don’t underestimate the 22” height!  This is more than enough and my chair fits comfortably at the desk fully extended or a regular desk at the lowest setting (and everywhere in between.). The cylinder is smooth, quiet and very well made. Great quality and highly recommend.
