Which one to buy
California King is bigger on both edges, 2.9 cm wider and 13.4 cm longer. It is the straightforward upgrade, and the 2.9 cm of width is also 2.9 cm of floor you no longer have.
Does the same bedding fit both?
No. 13.4 cm of length is far outside what a fitted sheet absorbs. Buy for the size you own and read the centimetres, not the label.
Space per person
Shared between two adults, California King gives each sleeper 91 cm and Super King gives 90 cm. For comparison, a single bed is 90 cm wide, so anything under that is less room each than a single bed gives one person.
