REK is an expandable bookcase that grows with your book collection. The more books, the bigger the bookcase. The zigzag shaped parts slide in or out to accommodate books in the resulting voids. Regardless of the quantity of books, REK will always be full. Books can also be arranged according to their size. The narrow spaces are excellent for magazines.

So thin it looks almost invisible. It’s lightweight form looks fragile but its surprisingly strong and very stable. It’s only 6mm thick, and comes in 4 heights, 12 tabletop sizes and a number of finishes. Designed by Tobias Berneth for Karl Anderssen.
