On my airplane, the FA crew rest area is in the aft ceiling of the aircraft. It is accessed by a ladder and an opening in the ceiling. For the longest time I wondered why some of our wide-body FA's complained so much when first class was full. Then it hit me...they needed one of those seats for their crew rest because they couldn't fit through the large hole in the ceiling; much less climb the ladder. These same ladies did need to turn sideways when walking down the aisles.

And by the way, I'm not kidding.
