Personally, I really love this idea. I am not one of those "let's make the bed look perfect" kind of people. When I try, it just does not look cute. At best, it looks boring. I can arrange flowers and decorate at Christmas but I am not a bed maker. I can, however, close a cabinet door! I say, let's do this!!! --->not your average bed in a cupboard<---
As I one day plan on stuffing multiple boys into one room, I love this. Creative, cheap, and the boys get to feel like they live in a tree house. What kid wouldn't love that? Such a nice change from the standard 'stuff a few bunk beds in there' solution.
