I will whitewash my attic someday and add built in bunk beds for the ultimate sleepover room!
A company called Blandito has designed a circular, foldable pillow that can be manipulated into many shapes (bed, chair, cubbies of different kinds.) Extra larges for adults as well as children's size. I can see this being great biofeedback for sensory averse/craving children. Too bad it's still in the design phase!
The artsy-ness of this image makes it tough to tell, but I think those are wood walls with each plank stained a different bright color. Or it could be a pastel drawing on the walls. Either way - Totally cool. (Have tried desperately to find where this image originally came from with no luck. Obviously from some magazine.) (Oh, the polar bears are cool too!)
