I took my idea from "Rast Sensory Table", so I thank its creator.
I bought two RAST nightstand for 9,99 €(one) and hacked them.
I screwed four shorter wooden board in a little armchair, and the longer ones in a little desk!
I also screwed a pink PS VALLO on the right side, very cheap and agreeble look, it contains papersheets, drawing pens, pencils etc.
Funny, cheap and usable!
