The added length can help accommodate taller individuals, and the narrower width compared to a standard king mattress can be suitable for couples who prefer less surface area between them.Active sleepersIf you tend to move around a lot during sleep or prefer more room to spread out, a California king mattress can provide the space you need. The extra length allows for more freedom of movement without feeling confined or restricted.People who sleep with a pet at their feetEven if you’re regular height, the extra length gives your pet room to curl up at the foot of the bed.
