I have a recurring fascination with creating an unusual bedroom for my kids... something cozy and unique. My own childhood was filled with requests for bunk beds, hammocks, and other bizarre beds; my parents never relented, and I spent my childhood sleeping on one very unremarkable twin bed (dressed in various comforters over the years).
I'm sure I'm living out my own childhood fantasies, but here's my latest find:
Suspended loft beds!
Screwed into the wall studs on two sides, the mattress frame has just one unsupported corner that is held up by heavy-duty cable that extends into the attic to loop over pipe straddling two attic joists. It's reportedly amazingly stable, and much cheaper to build than traditional loft or bunk beds because of the reduced amount of lumber used.
Someday, when they're a bit older, I want to do this for them. Fantastic.
