6'1" here. Just came over IAH to Lima last night in a 767 Polaris seat. Putting the seat into bed mode makes it nearly flat but your feet are angled into a cubby pocket. I found that my toes were crushed in to the cubby when I allowed my body to follow the natural recline of the seat. In order to not be smushed in there I had to slide upwards in the seat elevating my torso a bit and the lumbar support was pretty much on my buttocks. Laying on my side provided more room. But by no means was this comparabl4 to the comfort of the Arab/ME state subsidized airlines.
