The Cloud bookcase by Ronan & Erwan Bouroullec, with hollow compartments, is an extravagant decorative element with a pop touch and an absolutely unforgettable design. Manufactured using rotomoulding technology, in white polyethylene, Cloud is a double-sided bookcase that adds lightness to any environment, forming a configuration that can be customised by the buyer: the modules can be interconnected at will, by means of a retractable joint, to create a beehive structure.
