I recently got an email asking which of the bedroom sets for the Kaleidoscope House were rare. You’ll remember that there are two versions that were sold: the one with the bed frame and plaid headboard and the one issued with the “box spring” mattress. In all honesty, I am not sure which of the two is considered “rare” but my guess is the one with the plaid headboard would have had less units circulating in the market since it was the first version of the bedroom set. Does anyone know for certain? Looking at the pictures above, you can see a reason why they would issue a second version. The bed with the plaid headboard doesn’t fit very well in the room’s dimensions.The Kaleidoscope House does appear to have had several different bed prototypes. See pictures below. Also note the ladder to the sleeping loft and the opened version of The Big Idea.
