Frees up space in the guest room. Nice looking alternative to a murphy bed. Includes a firm memory foam mattress that folds in thirds to fit into the cabinet when closed. Not as convenient as a murphy bed because you have to pull out the base to set up (takes like 1 to 2 minutes, not a big deal) and then make the bed. Kind of inconvenient for daily use, but nice for occasional guest use. Again, the memory foam mattress is pretty firm, which I like. If you wanted to change out mattresses, you would need a 6" mattress that folds in thirds. A regular mattress will not work. That's probably the only down side of this lovely piece of all wood furniture.
