Here is an interesting and very cool idea for some bookcase extra storage space. “Plus One” comes from Matthias Ries and it has a fresh and youthful feel. This unusual shelving addition is not only functional, but also surprisingly sleek. It can help improve the look of a dull bookcase and it can also emphasize on those books or magazines one considers special. An the same time, it makes them a lot easier to access. “Plus One” could also be used for storing CDs, pencils and so on. This cool shelving extension comes in a walnut or maple finish, which makes it pretty exclusive. There is also a knitted “decorative” element available, in order to connect the addition to the shelves. What’s your opinion? Could this item really be useful?
