Dimensions of a Full Size Mattress & Boxspring
People often shop for a mattress based on its comfort level or based on the offerings of specific manufacturers. But the mattress size is also a factor you should consider, especially if you are part of a couple who will share the mattress. A matching box spring is important to your comfort on the mattress and contributes to the life span of the mattress.
Full Size Measurements
A full size mattress and box spring set are a step above a twin size set in terms of size and underneath a queen size set. When you size a mattress, the measurement for the width is usually listed first, followed by the measurement for the length of the mattress. A full size mattress and box spring set measures approximately 53 or 54 inches in width, and 75 inches in length. The thickness of these mattresses vary and can range anywhere from only 6 inches thick up to 18 inches.
Full Size Comfort Considerations
Because of its dimensions, a full size mattress is only suitably comfortable for sleepers up to a certain height and is not usually suitable for men in particular. Because it is 75 inches long, a full size mattress is recommended for a shorter adult, with a height of 5 feet 5 inches and under, or a child. The 54-inch width is basically only enough room for one person to be comfortable. If two people sleep in the bed, it divides the space into only 27 inches for each person.
Comparison to Other Sizes
The full size set is 15 inches wider than the smallest size bed, which is the twin size. The twin size is often called a single mattress, and the full size is often called a double mattress. The standard mattress size directly above full is a queen size, which measures 60 inches by 80 inches. Sometimes a size is also offered that falls between full and queen, called the full XL, or full extra-large mattress. It measures 54 inches by 80 inches, giving it the same length as a queen size.
Box Spring Importance
When you buy a new full size mattress, or any size mattress, you should also buy a new box spring to complete the set. A new mattress placed on top of an old box spring, which provides the foundation for the mattress, only helps shorten the life of the mattress by not giving it the adequate, sturdy support it needs. It also impedes you from getting the maximum comfort. Verify that both the mattress and box spring are the same size.
