The king sized mattress is the ruler of all other mattress sizes, the king is certainly the most sizable. King mattress sizes make them perfect for master bedrooms, and these beds are excellent for couples who like to have their space when they want it. King beds are also great if you find yourself sometimes bedding down with your children next to you, or if you have some cats and dogs that think it’s really their bed. There’s also that undeniable satisfaction you get when you brag to your friends you’re sleeping on a king-size.

More About King Mattresses
Your standard king mattress is also known as the eastern king mattress, since there’s an additional type of king called the California king and, obviously, California is to the west.
The King is the largest of the standard mattress sizes, providing couples with spacious comfort even when sharing the bed. Firm King size mattresses are designed for couples where both sleepers enjoy a medium-firm to hard level of comfort, or where one or both sleepers need solid support to avoid waking up with a sore back. Side sleepers generally do not do well on firm mattresses, as the dense sleeping surface is too unforgiving for the outlying hips and shoulders. But if you and/or your partner enjoys/needs a firm sleeping surface, you won't beat the spacious luxury of a King.
