I expected the seat to move. It does not. Disappointing. Also doesn't move well on plastic chair guide for under the desk. We bought that at the same time we bought the chair. It’s an okay chair but not great. I suppose I need to spend hundreds of dollars to get a ‘great’ chair.
I am trying to enjoy this chair the height that the chair goes up the comfort of the elbow on the chair and the comfort of the Head rest however when I set the chair height it slowly goes down. I have to continue to raise it up. That is the only thing that I don't like.
