I have found these beautiful comforters that they fill children's dreams with fantasy, and they decorate their room beautifully. The company that designs them is called Snurk and is Dutch, although the product is manufactured in Portugal.
The photographs are a bit stereotyped because the boy sleeps like an astronaut and the girl like a princess, but who says your sweet daughter doesn't want to become a space traveler for a few hours? 
There is also a version that is shaped like an elastic trampoline for jumping. The sets include a cushion cover to increase the effect. The material they are made with is 100% cotton.
On the web, the company ensures that shipments can be made anywhere in the world, and the price (not including shipping costs) is 59.95 euros.
They are very original and fun, don't you think?
Upgrade: October 2013, they inform us that in the Cadoca store you can get these comforters in 48 hours for € 50 + shipping costs
