what is the luxury soft sleeper coupe of the train #3 like?

I have booked 2 tickets for the luxury soft sleeper. Now I am told that this coupe has upper and lower bunk. We are both elderly and I worry how will I climb to the top bunk. I found one picture of such coupe but it didn't even show any ladder for climbing up there. Does anyone know this sort of coupe or have some pics of it? I would much appreciate your information.
