Overview

Measuring 76" wide and 80" long, a king size mattress provides plenty of space for a couple to sleep comfortably. Not every bedroom can fit a king mattress, so be sure to measure that the king mattress size is not too big for your sleeping space before getting your heart set on one of the many king bed mattress options available. Simmons was the first company to market the king mattress size.
