The cradle was designed by a team headed by Slovenian innovator Erika Drobnič, who has developed a multi-purpose cradle that is marketed under the brand name Kiara.

The cradle to be presented to the Duke and Duchess of Cambridge is quite special. "We've redesigned this cradle to change its shape and add two new materials, glass and lace," Drobnič was cited by rtvslo news site.

The idea for the royal birth present was first presented at the Slovenian Embassy in London in November last year.

It took Drobnič's team several months to make the cradle, which is made of Slovenian wood, precious glass made by Steklarna Hrastnik and Idrija bobbin lace.

The team are confident that the royal couple will also use the Slovenian present.
