The pirate bed is AMAZING! I love the tree bed, too...
On my own bed, I have a beautiful eggplant-coloured canopy... I sleep better with it, and it gives my day bed a romantic, New Age feel... I also took strings of garland (mine is gold, with moons and stars) and wrapped it around the bed frame...Doubling up comforters also helps. I have two -- a standard cotton one, and then a down filled one on top.
