IKEA is the world's largest furniture retailer. The company originated in Sweden and has now moved to the Netherlands. They designs and sells ready-to-assemble furniture, appliances and home accessories.
Like many of the world's leading companies, they use Joomla. Ikea's websites for Kuwait and Saudi Arabia are both built in Joomla.
The Saudi Arabia site is in Arabic - it's great to see so many big organizations starting to employ Joomla for right-to-left sites.
