Babynests seem to be a Nordic thing, I guess? Personally, I had never heard of them until I read your comment. For what it's worth, the US market seems to be quite unexplored, something you might want to consider. They look really cool, although there might be some safety concerns. I think that US pediatricians are currently unanimously recommending flat empty cribs / bassinets (no side padding or loose blankets) for newborns.
