Chair has great features. The base is solid and the tilt of both the seat and also the back are quite comforting. Being able to lock your preferred position in place is a very useful feature as it prevents the kids messing with the settings. Head rest is nice and the chair does 'hug' you well and keep all your lumbar support in the right positions.
I love this chair I have had no issues with my back since I got it. If I sat in my old chair for any length of time just standing up was pain full. It makes it easier to sit in a proper position with the supports where they help the most. I would definitely recommend this chair.
