Replacement gas spring

Fits just right. Easy to remove. Easy instructions. Works well. Bought a 2nd. Glad to purchase from your company.


Very simple and Quick Repair. Kept the chair from going to the trash heap and saved a lot of money.

My Chair now Works

I bought the replacement cylinder. The only issue I had was the allen wrench didn't quite fit into the space after I put on both rings. I had to force it and it was difficult. But I did get it to work. Definitely follow the directions. I skipped the part where you can't line up the rings and it made things bad until I fixed that. Then it went well. I would definitely recommend this as an easy cheap way to extend the life ofyour chair.

nice replacement tools and parts and instructions.

Quick and easy!

My sweetie was suffering from a sore neck. Her office chair would slowly lose height and she would end up with bad posture. I located this product and watched the videos and chose to order the replacement kit.
It arrived the next day. I was pleased and went to work. The removal tool is very easy to use.
The remaining bit, the base, not so much. As indicated, there only brute force that will remove the base, so I placed a couple of leftover bits of oak flooring on my bench vice and pulled out my 3lb hammer. It took some smacking, but finally the old, leaky part hit the floor and I could place the new parts in the chair base. Very easy, once that was done.
I like the new cylinder, and now her issue is that she has to lower the chair to the correct position, instead of raise it. What novelty!
Suggested it as a solution to a co-worker who is using a folding chair since his office chair cylinder failed.
