Our DD was always relegated to the sofa bed. As a 5' 10" adult, she was thrilled to be able to sleep in the Murphy bed on our recent Treasure cruise. She found it very comfortable and loved having a USB outlet for her phone within the frame of the bed.
I had the sofa bed on our Treasure sailing and it was perfectly fine. It was not as amazing as the regular beds on the other ships (and probably the Treasure but I haven't slept in one to say), those are just the best beds ever, but I had no issue with the sofa bed at all.
