A super king duvet cover is big enough to accommodate a super king duvet, which measures a generous 260cm x 220cm. A super king duvet cover is 30cm wider than a king size duvet cover (yet the same length!). If you want something larger than a super king duvet cover, opt for an emperor size duvet cover, which is an impressive 290cm x 235cm. When you're buying a duvet cover, it's important to make sure you're choosing the correct size for your duvet. Buy one that's too small and you'll have a lumpy, uncomfortable bed. Buy a duvet cover that's too large and you'll find your duvet moves around inside the duvet cover, meaning an uncomfortable night's sleep and an untidy looking bed. It's easy to check your duvet size. The label on your duvet will tell you what size to buy. Can't see the label? Use a tape measure to check. Your super king size duvet cover needs a duvet that's 260cm x 220cm. 

If you've seen a super king duvet cover that you love, but only have a king size duvet, you might wonder if it's a good idea to buy a super king duvet cover for your king size duvet. We'd recommend against doing this. That's because for the most comfortable night's sleep and a bedroom that looks welcoming, it's best to buy a correctly sized duvet. A king size duvet won't fit snugly inside a superking duvet cover and will move around - you'll find the duvet bunches up and that the duvet lies unevenly as you try to sleep. So, if you have a king size duvet, choose a king size duvet cover. And save your superking duvet cover for a superking duvet.

The type of duvet sets used by hotels for super king beds depends very much on the type of hotel. Generally, hotels like to make life easy for themselves and choose white super king duvet sets, perhaps with a subtle pattern such as a dobby stripe or a marrow stitched border. These look elegant and suit a wide range of interior design schemes, especially when paired with a throw or bedspread. It's normal for a hotel to use cotton super king duvet sets, as these are easy to wash, dry and iron. They can also be bleached to remove stains if necessary.

Here are some things to consider when buying a bed set.
