closet-turned-nook love it! we do this to every closet Bear has ever had =) he loves his very own special place. Its never this awesome or large, but it is his space he gets to decorate himself. Closets as kids spaces is so great.
Simple stack of multiple fabric-covered foam pads. makes a cushy "sofa" in the playroom, and can be pulled apart for multiple sleepover guests, movie night pillows, or tumbling games, etc. (they have fabric covered foam mattresses at Jysk)
Storage beds made from old kitchen cabinets with a secret hangout spot. Want this for my girls when they get older! Better than bunk beds! The secret hangout spot is great, wish I could fit in it myself.
