Winner of the Compasso d'Oro Award in 2004, the Ptolomeo by Bruno Rainaldi is one of the world's most inventive storage pieces and was inspired by the astronomer Claudius Ptolemy, an important thinker and prolific writer on astronomy, philosophy, music theory and geography. Based in Milan, Bruno Rainaldi has been the Professor of Design at the Academy of Brera since 2002 and is well known for his design work across furniture, lighting, storage and kitchen collections. The Sapien collection is his most well known design, an artful, interactive piece in tune with an international shift that blurs lines between art and design and encourages participation.

Perhaps also taking its cue from the architectural skyline of a city like New York, the Ptolomeo bookcase collection of thin towering 'structures' is robust and highly flexible allowing a range of storage possibilities, and more than 50 small and large books to stack up vertically. The more you stack the more interesting the structure becomes – colour coded, assorted or pared back, the re-arranging is all in the fun.
