California King Size Mattress
At a whopping 72 inches by 84 inches, the California king size mattress is designed for taller people who need more room at the foot of the bed. While a California king mattress is four inches longer than the standard king bed, it is also about four inches less wide than a standard king bed. The California king was first introduced in the 1960s as the bed of choice for professional athletes and celebrities.
