Kamprad's three sons, Jonas, Peter, and Mathias, are now in their early and mid 50s.

The three Kamprad brothers are media shy and have rarely given interviews, according to The Local Sweden.

In a press statement following their father's death, the brothers pledged to keep the company true to their father's vision.

"We, the sons, have promised him to sustain his legacy and do what we can to ensure the core values and the unique IKEA concept are carried on into the future," they wrote.

The Kamprad brothers own Ikano Group, the $9.1 billion company that was created to manage Ikea's real estate and financial service businesses, but became an independent entity in 1988.
