Bubble is much more than a bookcase: it is the pleasure of putting things in order, giving each object its natural location, the one they would choose if they could do it themselves. High and low, wide and narrow, short and long: each object coexists happily within this extended family where, instead of the traditional shelves, there are removable ones and colored bubble-shaped trays that can be moved at will along the horizontal crosspieces. And where there are no shelves or trays, Bubble transforms into an architectural framework that showcases objects of different height, as in a skyline.
