At least once a year Reinier de Jong designs a new piece that catches our eye, and for 2012 he's graced us with the REK coffee table, related to his expandable bookcase design of the same name.

The Rotterdam-based designer has incorporated the perfect-fit sliding panels of that bookcase into a smaller package, creating an adjustable piece of furniture that grows or shrinks with your needs.

Concealed, built-in stops ensure you don't pull a particular section out too far, and if you're wondering where you're meant to achieve some purchase with your fingertips, look to the subtle bevels on the inner edges of each slider.

The REK, which comes in oak, birch or beech, with laminate on particular surfaces, will stretch from a 60cm x 80cm box out to 130cm x 170cm.
