    PERFECT HEIGHT
  

*by B***L on Reviewed in the United States on 5 April 2024*

I had another lift cylinder that was just too high. I ordered this one, replaced it and it is now the perfect height. I weigh 300 pounds and it handles my weight nicely. No problems at all. YES I would be glad to reccomend this gas cylinder lift to anybody.

### ⭐⭐⭐⭐⭐ 







  
  
    Upgraded my new Aeron chair easily with the 7.6" model
  

*by D***R on Reviewed in the United States on 23 June 2023*

I am a tall person, 2 meter (I think it's almost 6.6 feet) and as great as my Aeron chair is, it was not heigh enough for me to sit straight, which caused some knee pains etc.I saw this product, and thought this can be a good solution, as there aren't so many products for tall people out there.And it worked!I had a bit of concern if this is the right piston, but after some Youtubing, I understood how to check, and I was glad to see that it is suitable.The installation itself was relativity easy, required some strength and an hammer but it did not take more than five minutes (again, thank you Youtube!) and I got me at last a normal size chair! (for me at least)At it's maximum length it is ridiculously high, at wobble a little bit, but when I take it down a bit to the right height, it is stable.So, I am happy, works great, suitable for the new Aeron chair
