Trolleys rallying down aisles, endless checkout queues, and flat-topped boxes crammed to the ceiling, this is IKEA, a Swedish do-it-yourself chain. IKEA revolutionized the look of young people’s interiors with inexpensive furniture. The general philosophy of IKEA is democratic design, and that means form and function at an affordable price. Affordable and simple, IKEA hands the screwdriver over to the customer. Founded in 1943, the company rapidly became the preferred interior shop for students, singles and young families. Annual sales now exceed six billion dollars.
    But success is followed by imitation and competition. All the sort of classic department stores are desperate to break into that area, and are doing it in a much more imaginative way. IKEA plans to fight back, using design as its weapon of choice. The company started to work together with designers in the beginning of the 50s. Their proposition clearly is simplicity and good value and very good design. IKEA’s new PS range, takes the furniture supermarket, up-market. The PS range is a range that’s supposed to be a little more modern, a little bit more designer focused. And as IKEA wants to push more on the designers, this collection is quite important for them. And IKEA hopes the PS range will distinguish it from its competitors and imitators, both aesthetically and financially. But the PS line is not expected to reassemble the company’s profitability as quickly as one of its bookshelves. Many say IKEA’s long-term success still depends on following its founding principles. Design married to function and affordability.
