Dude you have no idea. I have to drive an 09' Escape for work and it has the worst seats I could imagine in any vehicle other than a Yugo. You have to tilt your head back at a 30 degree angle to make contact with the headrest, and the seat foam wore out many miles ago, so I feel all the ribs of the seat bottom and seat back frames. Ugggg.
The good and bad news about the headrests in the CX-9 is that after 3 and a half years, I got used to them. I am no longer bothered them. But this is because my neck has gotten used to leaning forward slightly so my head doesn't hit the headrest. This can't be good for posture or long term neck/back issues.
