Ikea is known to have revolutionised the way we buy furniture by laying out the store to take you on a journey through different rooms so you can see items in situation. To launch a new store, Ikea decided to turn this idea on its head - well, not 180 degrees but 90 degrees - by laying out its wares onto a vertical billboard to double as a rock climbing wall. To have a go at clambering this wall, you’ll need to flat pack…I mean, back pack with your climbing gear and head to Clermont-Ferrand in France.
