Anybody LOVE their mattress? My wife spent a lot of money on a 'nice' King sized mattress probably 10 yes ago and haven't had a good nights sleep since. Looking to finally bite the bullet and get a new one, but don't want to make the same mistake again. I know some people love the sleep number beds, but I have slept on them before and didn't really care for them. The last thing I want to do is go to a mattress store....worse than used car salesmen.
