To begin with, koalas are not bears.

Secondly: no, they do not sleep upside down. They have specific structural adaptations for trees, which do not include any method of sleeping upside down, as they do not have tails. Koalas have sharp claws with opposable thumbs. This gives them extra grip for staying in trees. They also have thick padding on their bottom which helps them to sit comfortably in trees.
