Recently cruised on the Beyond, with 3 people sharing a "double sofa bed" cabin configuration. Double sofa bed means:
- Sofa has a trundle bed configuration (one bed slides out from under the sofa)
- A mattress can be put on top of the sofa seating area for a 2nd bed
During our cruise, we never used the trundle bed. I slept on the mattress placed over the sofa seating area. The mattress was kept in place throughout the cruise, even during daytime.
- The mattress-on-top-of-seating-area was comfortable enough for me. Some people are very fussy about mattresses and may not have the same opinion.
- This bed was more narrow than a twin bed. I am on the smaller side. A larger person may have an issue with the narrowness of the bed.
- Because the sofa seatbacks were removed to accommodate the mattress, and the sofa height was increased because of the mattress thickness, the sofa was not particularly comfortable to sit on as sofa seating.
