My son was in need of a new desk chair because his old one wouldn’t roll smooth. It was so hard for him to roll back. This is super smooth rolling and sit up well giving him good posture. It’s easy to wipe off if something spills on it and the black goes well with his black and gray bedroom. He can raise it fine but he’s not heavy enough to lower it so I always have to help. He’s happy with his chair and I’m happy that he’s happy.
