I have a Cal King mattress. It’s hard to find comforters that have additional length and width for overhang on this size mattress, that aren’t extremely expensive. This comforter has more than enough to cover the whole bed! It’s weighted enough to keep you cozy, and your not sweating. My husband is always hot, even in the winter, so I was a little skeptical at first. He loves this comforter! He says that it ‘breathes well’ for such a thick blanket. It’s super soft too!
