Got PY for YYZ-PVG.

I flew 13A last year YYZ-PEK and did not sleep much. 12A fully reclined for the whole trip and required gymnastics to get out of my seat when I needed to use the bathroom.

Eyeing 12A/K now (need window side to sleep). I know there is no leg rest or foot rest. Will the FA be ok if I take my carryon out of overhead and put it flat on the ground to serve as a foot rest?

I’m only 5’4 and need some sort of foot rest to sleep well
