Conceived by MicroWorks, the 4 Degrees Book Shelf system is designed to solve the problems of incomplete libraries. On a flat shelf, if one can’t fill all the space, books are required to lean. With a shelf built on a 4 Degree lean from the get go the issue is resolved. Apart from obvious use benefits the angularity of the design also forms a set of pleasing lines that makes the shelves a good fit for open spaces. (via Industrial Design Served).
