If you have the choice go for Super King Duvet, but its up to you to decide if a king would be OK. If its going free than accept it and give it a try, if its expensive then buy the correct size. Is it a new bed?
Yes it's a new bed .. I've actually ordered a super king size but it hasn't arrived yet but was thinking about exchanging it to King size as we are using double at the moment and it just fits but with no over hang plus I think there's a lot more bedding options with king size .. just wanted to see if anyone else has a super but just uses a king
You could do like the germans do, and have one single duvet each. You can actually buy wide enough fabric for super-king-size quilt covers in some places, like Birmingham markets. Sheets, however, would be a problem, unless you wanted a seam down the middles.
