I've heard different opinions from two people. Both have super king beds and one says king sized duvet is absolutely fine - makes it easier to buy covers, make the bed etc. The other says absolutely not, get super king duvet as it looks silly otherwise.
So, what is your opinion if you have a super king? I've got 3 weeks before we move and put up the new bed! I need to make a decision and don't want to make a mistake!
