This is a really comfortable chair. I've only had it a couple weeks but so far I'm impressed. I like the head rest and the ability to adjust the tension for recline or lock into a few different positions. I can sit in this chair for hours without getting stiff or sore.
The only complaint I have is the head rest does not allow for enough adjustment. I had to remove the head rest. It was too low for the length of my back and neck but for others I am sure it’s just fine
