My daughter loves this chair.  It does her and her cat comfortably since he joins her for online school. The arms go all the way up so it's easy to push into her desk without lowering the whole thing when she's done for the day.  It was easy to put together.  It rolls nicely,  though we did get a carpet protector.  She also enjoys the lumbar support which she dusky think she needed when we were looking at the chairs.
