Completely unsuitable for anyone over about 5'8" (and even that would be pushing it) - it's not adjustable enough and the headrest and back panel assume you are short.
Due to COVID19 I’ve been working from home. I’ve utilized all my chairs here and they all killed my back. Finally decided time to invest in an office chair and man do I wish I had done this sooner! The associate there (sorry I forget his name) was very helpful and patient. I’ve had this chair for two weeks now and my back doesn’t bother me anymore my neck doesn’t hurt I am able to work comfortably !
I'm 6.1 and the headrest is way too low. It digs into my shoulder blades even on the highest setting. I went with this chair because of all the positive reviews; however I wish I would have searched through them to identify those written by tall people. I would say if you're 6.0 or taller - buy at your own risk as all those reviews complaining about the headrest causing discomfort are absolutely accurate.
