We've had the same problem with "king" sized for years. However, I've "sort of"solved it. Thanks to my husband who is European and wants his OWN blanket. So I now have twin sized comforters, cover them with twin size duvet covers, and that's that. No top sheet. Only problem is I have to buy each item separately, so I've figured out a way to make my own comforters with the top sheets that come in a sheet set. And I don't have to "make up" the bed each day, just fold up the comforters, and let the bed air out. Works great.
