This cool modern bookcase was first designed in 2008 by de Jong – REK is a bookcase that grows along with a book collection. The more books you have, the bigger the bookcase becomes as zigzag-shaped parts slide in and out to accommodate books in the resulting spaces. Books can be arranged according to their size and narrow spaces used for magazines. The new REK has the same dimensions as the first one but weighs only 80 kg and the maximum dimensions of bookcase are: 202 x 228 x 36 cm, the modern version is lighter and more sustainably built. The guidance was improved the guidance and was added a stop, making sure the parts do not slide out too far. Enlarge your book collection and your bookcase accordingly!
