They must exist, as the seats in this plane are designed for them. I know the seat pitch is designed for economy, but why do the seat backs have a ‘headrest’ that would only work if you were about 5 feet tall? My shoulders are clear of the top, and I’m only 6 feet. Start of headrest is below my shoulder blades.
Edit – viewing this on a proper screen now I’m home, I can safely say that this is one of the worst photos I’ve ever been in. Serves me right for taking it!
