A bed is named after the mattress size it's built to hold, so a king bed frame takes a king mattress. The frame itself is usually a little bigger. European (continental) sizes aren't the same as UK ones and can vary between brands.

Bunk beds and high sleepers have a maximum mattress depth set by the manufacturer, so the safety rail stays high enough.
