There are indeed carriers that now provide much nicer bedding. I fly mostly Delta and United, and United has definetively the best bedding not the routes I fly (mostly to South America and occasionally Europe). In business class you get a blanket, a duvet, two pillows and you can request a mattress pad. Delta has a nice heavy blanket that I usually sleep on top of and a pillow.

Both carriers in the process of upgrading their seats in business class and adding a true premium economy product, not what delta calls comfort plus, which is really just more leg room at the front of the economy cabin. The true premium economy product is much closer to the premium economy that has been available on other carriers (emirates, cathay pacific, etc...) for a while and has better seats, food is served on plates, etc... It's not to far off from what one might get in a domestic first class.
