Overview

Slightly longer and not as wide as a typical king mattress, the California king mattress size measures 72″ wide and 84″ long. A California king size mattress is perfect for taller couples who need more room at the foot of the bed than a queen or king mattress provides. Check out our broad selection of California king bed and mattress options available, including some at sale price. Developed in the 1960s, these mattresses originally catered to professional athletes and celebrities.
