When I first reviewed this chair I read about the headrest discomfort for tall people. I am 5'11" and ran into the problem of the headrest hitting your shoulders when seated. I ran out to Lowe's and bought some Flat Washers 3/8" put 4 on each side between the chair back and the headrest. I think you will like the results!!
Love the chair. It is so comfortable and supports by back beautifully. I am a large person and it definitely accommodates me well. Definitely a great buy.
