Double vs. Full Mattress Comparison: Which Is Best? Update 01/2022

There is a 54-inch by 75-inch difference between a double bed and a large mattress. Double bed and full-size mattress are often used interchangeably.

There is no difference in the dimensions of a double or a full mattress. Even though they’re termed “doubles,” regular full beds aren’t big enough to accommodate two adults.

During the 1870s, American furniture manufacturers standardized the dimensions of double beds, and the term “full” was coined. In the United States, twin beds became the usual size for a single bed, and large mattresses became the typical size for a double bed.

What is a Double Bed?

Before the introduction of queen and king size beds, couples preferred double beds. It’s difficult to get a decent night’s sleep on a double mattress because each sleeper only has 27 inches by 75 inches of room.

In the 1940s, the majority of Americans slept on twin and full-sized beds. King and queen beds were introduced in the 1950s and quickly became popular. Larger beds were in high demand at this period due to the fact that the average height and weight of Americans was rising.

This boom occurred in the United States following World War II. A larger mattress was needed by wealthy residents who owned huge homes in the suburbs. Double-sized beds have fallen out of favor as a result of all these new trends.

What is a Full Size Mattress?

It is the same size as a double bed to have a full mattress. In college dorms, full-sized beds are the norm. They also work well in smaller spaces like studio apartments or dorm quarters.

In a room 10 feet by 10 feet, you can fit a full-sized bed. When arranging your bedroom furniture, keep in mind how much room you’ll need to move around and for people to pass by. Except for the side near the wall, you should leave at least 2 to 3 feet of room around your bed.

Our Amerisleep Full Size Mattresses

Five different firmness levels are offered for our Amerisleep Mattresses to accommodate different body types and personal preferences. They come in soft, medium-soft, medium, medium-firm, and firm varieties.

All of our mattresses are made with Bio-Pur®, a plant-based material that keeps them cooler than other types of memory foam. A soft and absorbent material is used to make our mattress covers, which help to keep you cool and comfortable.

In the second layer, we have Affinity with HIVE® technology. This layer relieves pressure points and eases discomfort. It accomplishes this by providing additional head, back, and leg support, as well as shoulder and hip padding. The Bio-Core® layer is located at the bottom of our mattresses and is responsible for their sturdiness and longevity.

Hybrid variants are available if you prefer a bouncing bed. Airflow is enhanced and motion transfer is minimized thanks to a foundation layer of individually wrapped pocketed coils. Medium-firm, medium, and soft hybrids are all options for our hybrids.

Double XL and full XL mattresses are also available in double and full sizes. These mattresses, which are 54 inches wide by 80 inches long, are 5 inches longer than a typical double or full size mattress. To accommodate tall sleepers, the extra inches are useful.

Variations of the Full Size Mattress

Many mattress stores and internet retailers do not carry the double XL or full XL size options. When looking for a full-size mattress, we recommend doing some research on the brands that carry them before going to a store or shopping online. These sizes are so uncommon that it may be difficult to obtain bedding that is appropriate.

Other Standard Sizes

While twin and twin XL beds are broader than a full, queen, and California king beds, a double or full size bed is narrower. Consider additional common mattress sizes if the double or full size mattress does not meet your needs.

Twin Size Mattress

38 by 75 inches is the dimensions of a twin mattress. It is a fantastic choice for children’s bedroom because of its small size. Even though single adults can use a twin mattress, there isn’t much room for limbering up and unwinding on it. Twin beds can also be used as bunk beds to save space in a small room.

Twin XL Size Mattress

This mattress is 5 inches longer than the standard twin size. For teenagers who are still growing, the extra length is a boon. The twin XL mattress, which is 38 inches wide by 80 inches long, is most typically found in children’s bedrooms and shared adult bedrooms. When compared to a full-size mattress, the twin XL’s dimensions are 5 inches longer and 16 inches narrower.

Queen Size Mattress

Mattresses of this size are 60 inches wide by 80 inches long. Compared to full-size beds, queen mattresses are 6 inches wider and 5 inches longer. Since queen-sized mattresses may be used by both single sleepers and couples, they are the most popular mattress size in the United States. Your guest room or master bedroom can each have a queen-sized bed. Particularly for those who suffer from insomnia, the additional width is a welcome addition.

King Size Mattress

Among all of the regular mattress sizes, a king’s width is the widest. For couples that need extra room to sleep, king-sized beds are an excellent option. The king-sized bed is large enough to accommodate youngsters who want to sleep alongside their parents on some nights, if they so want. In comparison to a full-size bed, a king bed is 5 inches longer and 22 inches broader.

California King Size Mattress

Of all the standard-sized mattresses, California kings are the ones with the longest lengths. For tall people, cal king beds come in 72 by 84 inches. The Cal king bed, like the king bed, is ideal for master suites with large square footage. This mattress is 18 inches wider and 9 inches longer than a typical full-size mattress.

Full vs Double Mattress: What’s the Difference?

You may be wondering why there are two different names for 54″ by 75″ mattresses.

The only difference between a full and a double bed is the size of the mattress.

A twin-sized mattress is referred to as a “twin-sized mattress” for the same reason. There are two names for the same mattress size a queen and a king.

  • After the Civil War, mattress sizes began to be standardized. “Single” and “double” were the only mattress sizes available to individuals in the late 19th century.
  • Even though it’s called a “double,” it’s just 16 inches wider than a 38″ by 75″ twin-sized mattress.
  • For this reason, “double” or “full” mattresses are referred to as such.

Up to the 1950s, couples slept in regular double or full beds. As the population grew taller, manufacturers began to lengthen the traditional king and queen bed proportions.

Those who are taller than 6’4″ may find a full-sized bed uncomfortably close to their shoulders.
