For its 40th birthday, IKEA has created a collection of its most iconic products and I bet you have at least one of them somewhere in your house.

IKEA turns 40 and has marked the occasion by launching a range of limited edition products, embarking on 40 weeks of deals and adding a 'time machine' to its website.

While I enjoyed finding out what happened when IKEA debuted in the US (metric measurements caused chaos and a lot of customers ended up with the wrong size kitchen cabinets) and learning the history of the brand's famous meatballs (the first version was the result of a delicious “10 months of testing and tasting”), the 40th birthday feature I most enjoyed diving into was IKEA's collection of iconic products.
