One of my least favorite aspects of airline seats is that it seems like the curvature is designed for someone of average height--which I totally get--but extraordinarily uncomfortable for people outside of that range. I'm looking at you, United economy regional planes. I'm 6'2", and the base of my skull lands exactly at a sharp, hard edge on those planes and leads to utter misery. I'm not sure how to fix that. Just bitching. This is the internet after all.
