So the wife and I have decided to upgrade from a queen size bed to a king. Obviously we need a new mattress. We've heard quite a bit about the sleep number beds, and how they're supposed to be the greatest thing since sliced bread, but the prices are, well, pretty high.
Does anyone here use one, and what are your thoughts about them? Are they as good as the commercials say? Will I regret spending $2500 on a friggin mattresss?
