This relatively normal looking wooden box transforms into the Pisa Tower shelving unit named after the famed Leaning Tower of Pisa. Unlike the Romanesque structure, these shelves don’t actually lean (nor are they Romanesque). Each shelf is however on a angle from the one below it and is actually balanced upon the top edges of it’s downstairs neighbor. An elastic rope through the middle adds to the stability.
The Pisa Tower was designed by Milica Nešovanovi to be a multi-functional piece of furniture. It works as shelves obviously but also when it’s in it’s compressed state the piece works as an end table or coffee table.
