Liberty Bunk Question

[txbluebon]

We will sail on the Liberty September 30 which we were able to book after our original cruise on 9/2 was cancelled. There are four of us, four generations, sailing together in one cabin. I read the description of the beds but don't know what a "single sofa bed with convertible bunk" is. To be clear, I know what a single sofa bed is but the convertible bunk is a mystery to me. Can anyone describe for me?
