What size is a super king mattress?

A super king size mattress measures 6 foot by 6 foot 6 inches, which is equivalent to W180cm x L200cm. The extra width (30cm more than a king mattress) offers you and your sleeping partner ample space for a comfortable and undisturbed night’s sleep. 

Is there a bigger bed than a super king mattress?

An emperor mattress is bigger than a super king mattress, but only in width. An emperor mattress gives you an additional 30cm in width, but both are 6 foot 6 inches or 200cm in length. Here’s a comparison of all the mattresses sizes we offer at Feather & Black.
