This coffee table by Rotterdam designer Reinier de Jong can be expanded by sliding the middle sections outwards in either direction.

The top and two sides are finished in white while the edges are veneered in oak, birch or beech. Stoppers prevent you pulling the inserts too far.

The REK coffee table is a continuation of his slide-out bookcase from 2008, which was one of our most popular stories that year. The bookcase grows with your collection and is included in the Dezeen Book of Ideas, which is on sale now for £12.

Here are some more details from de Jong:

REK is a coffee table that grows with your coffee needs. When you have visitors, just get some chairs and extend the table any way you like. Enough space for all those coffee cups and store your book or knitting set in the spaces underneath the tops.

You can extend REK in various ways. Built-in stops make sure you will not extend the sliding parts too far. Of course you can also put REK in a permanent position that fits your interior.

The top and two sides of REK are white HPL and the edges are finished with your choice of parquet wood: oak, birch or beech. The end grain side of the wood is beveled in order to get a grip: a subtle detail.

The dimensions of REK table obviously vary with its configuration. REK is 60 by 80 cm in collapsed state, its maximum lenth is 170 cm and its maximum width is 130 cm.

REK coffee table is related to another REK by Reinier de Jong Design: the bookcase that grows with your book collection.
