Perfect Replacement
My original cylinder had stopped working. This was a perfect fit and replacement for the original cylinder in my chair. The sales agent assisted me on a phone call in finding the correct part. I would buy from these guys again.

Works Great!
It works as claimed, and that is why this is my second replacement, on two different chairs. They do the job, very well.

Works great
Purchased this cylinder in October 2019. Half a year later it is still working great. No complaints! Great product! I used a pipe wrench, PB Blaster, and elbow grease to remove the old cylinder.
