Nice for you guys if you have the Boeing crew rest ( upper deck behind the flight deck) , that I have seen at an airshow and it has comfy seats to sit in as well as the bunk. At our airline the rest is in the tail ( we call it the torpedo tube , a totally diffferent design)
You cannot stand upright , its a long very confined space to move in ( the Cabin crew use it too). You cannot even sit upright on the bunk. To manouvre around you have to crouch and duck walk .There are no other chairs anywhere ( apart from the flight deck) where we can sit.
Bring on the freighter !!!!!
