is the footroom different in the 560 than the 550?
We have a 550. I am 6'2" with size 13 feet. There is plenty of room for my feet under the cabinet overhang.
The first night, when I rolled over while sleeping, I banged my shin on the bottom of the overhang. Amazingly, your brain figures this out, and you stop banging your shin when you roll over.
Keep in mind that even if you sleep on your back, your toes aren't likely to hit the bottom of the cabinet, because your feet aren't pointing directly up (90 degrees). Your feet are pointed toward 10:00 and 2:00, so to speak, not to 12:00 (straight up)
Perhaps if someone has size 17 feet they'd have an issue, but not size 13 and less, IMO.
Plus, it's better for most of us to sleep on our sides than on our backs, but I understand that each of us has our own physiology and needs.
