Can IKEA disrupt the furniture business again?

IKEA’s cheap products—and its knack for getting shoppers to walk away with bagfuls of adornments they never knew they needed—have made it into the world’s biggest furniture company, with €48bn ($53bn) in annual sales last year. The company, which is held privately through a bewildering network of foundations, controls around 9% of the fragmented global furniture market. In an effort to keep growing, it has been investing in its e-commerce offering and adding new store formats. Its latest experiment, in second-hand furniture, could help it get both bigger and greener.
