Since elementary school we know that gravity is a natural force that makes objects fall on people’s heads. US-based designer Alejandro Gomez Stubbs of Malagana studio employed gravity for doing exactly the opposite. The Equilibrium bookcase he designed is a combination of tilted shelving components that keeps things in place without the use of bookends. The modules are connected via hidden steel joints and look as if they are floating in the air. This weightless feeling is a disguise for a sturdy construction, that can withstand over 160lb. The piece can be assembled in minutes without the need of any tools or hardware, and, when disassembled, all pieces fit into each other for easy storage. The Equilibrium bookcase was shown at the American Design Club’s Use Me exhibition during the New York Design Week.
