I have slept on the Murphy bed a few times and it is comfortable. I slept on it alone, and w/my youngest DS. I didn't sleep on it w/another adult. My sister slept in the double bed alone and said it was very comfortable. I also slept in the bottom bunk alone & found it comfortable. Our kids LOVED the top bunk and Murphy bed! There were only four of us on that trip and we kept switching beds, to try them all out! We enjoyed the cabins a lot! Have a great time!
