My 220 lb., 6ft 2 son slept on the pull-down murphy bed in our Cat 4 Family Suite. It was fine for him, very comfy. Beware though, the only disadvantage is when the murphy bed is pulled down it lays infront of the door to the verandah. You can still go out to the verandah, but you have to climb over the bed.
It was a bit annoying only because our stateroom host was very prompt in turning down our beds, sometimes as early as 8:00 pm. It was hard for hubby and me to be all dressed up and want to go out on the verandah for some moonlight when we had to climb over the bed...it was a sight!!!!
