This is the Equilibrium Bookcase by Malagana Design. Stunning!
“With its cantilevered modules stacked upon each other at a single angled point, Equilibrium is a unique furniture piece that immediately catches attention by creating a sense of amusement and surprise.”
It might look fragile but it can hold more than 120 lbs (54 kg) worth of weight and it’s available in three different colors as well as natural walnut veneer. No word on pricing though.
