California King Mattress
If you are looking for maximum sleeping length, the California king mattress is your best bet. At 84 inches in length (or 7 feet) by 72 inches in width, the Cal king is 4 inches longer than the standard king but 4 inches narrower. And, compared to a queen size mattress, a Cal king bed still affords 12 inches more of sleeping width. The Cal king size is a great adjustable bed option because it has the additional length. Even with the foot or head of the bed elevated, you still get plenty of length.
