In row 7, the A seat is middle as per the other one seats. The F seat is essentially a two seat with one removed.

I prefer a cooler plane, but in either of those two seats I end up waking up frozen and hunting extra blankets, whereas in other seats I use the blanket as an extra back rest.

However as on two of the three occasions I have used these seats, they were on an overnight where I was OpUp'd from Y, I cannot complain too much, as I did sleep.
