Cute, but it seems like this is more of a bed and outside the glass doors is a reading nook. That's something I don't want: a nook that doubles as a bed. Like, no... Lol they're two completely different escapes. Of course, there are exceptions, but still.
Four beds make sleepovers the best! Everyone loves there own storage space, especially so close to their favorite spot - the bed! Kids always want to "live on their own". Give them that chance by building a mini house right under their lift bed.
