Book shelves rarely adapt to your collection of books and periodicals but here is one that does. From Reinier de Jong of Rotterdam the “REK” uniquely modern book shelf can enlarge with time and reading materials thanks to its interlocking zig zag structure. The REK Expanding Shelving System has the right sized space for all sizes of books and will always appear full. I think this decorative bookshelf would really look good with nice mixture of books and decorative accessories. The Design Studio of Reinier de Jong has a various selection of innovative furniture you can see here. I don’t know what this baby sells for, but cool usually costs.
