This wall bed is exactly what we needed in our guest bedroom.  It looks really nice and folds up easily.  It was relatively easy to put together but had a few nuts and bolts missing. One screw broke through the board and can be seen when the bed is open, unfortunately,  Other than that, it's doing exactly what we need it to do.

Pros: Looks good, fits regular queen-sized mattress
Cons: Missing screws, broken wood piece
