Twin or Single Size
More commonly known as a twin size mattress, it is also referred to as “a single.” This is a great size for children and teenagers. Investing in a quality twin mattress can sometimes last a child all the way to college.
Full or Double Size
More commonly known as a full size mattress, it is also referred to as “a double.” A full size is the same height as a twin but is wider. Its a great bed for a child that tends to move a lot from side to side.
The most popular mattress size, a queen is large enough to comfortably fit an adult couple. Its height is more than a twin and full, but the same as a king. Upgrading to a king gives more room width-wise (6 inches).
There are two types of king size mattresses: Eastern King and California King. The Eastern King is usually referred to just as “King” and is as tall as a queen but wider. The California King usually is shortened to “Cal King” and is taller than a regular king (4 inches taller) but less width-wise (4 inches).
