Does anyone else have this problem? With the seat upright and the headrest at maximum height, that lower tail of the headrest catches me in upper back and really hurts. The only solution is to crank the seat angle back a bit, but I'd rather be upright. Any ideas on this one? Both sides are the same, so I think it's working as designed. Maybe I have some other seat adjustment in an odd position. I can't figure it. Thanks for any comments or ideas! Oh, I'm 6 feet tall... Charles.
