A super king mattress is the largest mattress size. They measure 6 feet in width and 6 feet 6 inches in length. In metric measurements, they are around 180cm wide and 200cm long. By providing the most amount of space of all mattresses, they're ideal for those who love comfort, families with young kids and couples who like their own space.
