What is a Full Size Mattress?

What Is A Full Size Mattress

A full-size mattress, also known as a double bed, is a versatile choice for single sleepers. It measures 54 inches wide by 75 inches long, providing ample space for adults who prefer a bit more room than what a twin or twin XL mattress offers. This size is also a popular choice for guest rooms, as it can comfortably accommodate two average-sized adults for short stays.

Comparison with other mattress sizes

When compared to other mattress sizes, a full-size mattress is wider than a twin or twin XL but narrower than a queen or king. It’s the same length as a twin or twin XL but shorter than a queen, king, or California king. Here’s a quick comparison:

While a full-size mattress offers more space for single sleepers, it might be a bit snug for couples. For couples or those who share their bed with pets or children, a queen, king, or California king size might be a better option.

Now that we understand what a full-size mattress is, let’s delve into the benefits and considerations of choosing this size.

Who is a Full-Size Mattress Suitable for?

A full-size mattress, also known as a double bed, is a versatile choice that fits a wide range of users. It’s like the Goldilocks of mattresses – not too small, not too large, but just right for many people.

Firstly, full-size mattresses are a fantastic choice for single adults. They provide ample space for a single sleeper to stretch out, without feeling like they’re swimming in a sea of mattresses. If you’re a solo sleeper who likes to sprawl out or change positions throughout the night, a full-size mattress gives you the freedom to do so.

Secondly, full-size mattresses are a popular choice for teenagers. As kids transition from childhood to adolescence, they often need more space than a twin mattress can provide. A full-size mattress offers that extra room to grow, without taking up too much space in a smaller bedroom.

Lastly, full-size mattresses can work for couples, but it’s a bit of a tight squeeze. Each person ends up with about the same width as a crib mattress.

So, if you and your partner like to cuddle or don’t mind sleeping close to each other, a full-size mattress could work. But if you both like your space, you might want to consider a queen or king-size mattress instead.

Considerations for different body types and sleeping styles

When it comes to choosing a mattress, one size does not fit all. Different body types and sleeping styles require different types of support.

For heavier individuals, a full-size mattress can provide adequate support, especially if it’s a high-quality, firm mattress. However, if you’re significantly taller or heavier, you might want to consider a larger mattress, like a queen or king, to ensure you have enough space and support.

Sleeping style is another important factor. For side sleepers, a full-size mattress can provide enough space to comfortably curl up or stretch out. For back and stomach sleepers, a full-size mattress can also provide enough support, especially if it’s a medium-firm to the firm mattress.

In conclusion, a full-size mattress is a versatile choice that can suit a wide range of people, from single adults to teenagers, and even couples who don’t mind sleeping close together. However, it’s important to consider your individual needs, including your body type and sleeping style, to ensure you choose the mattress that’s right for you.

Now that we’ve covered who a full-size mattress is suitable for, let’s move on to discuss the pros and cons of full-size mattresses. This will give you a more comprehensive understanding of whether a full-size mattress is the right choice for you. Stay tuned!

Space Efficiency

A full-size mattress is a perfect choice for those who are looking to maximize their bedroom space. Its compact dimensions make it an excellent fit for smaller rooms or apartments.

Things to Consider When Buying a Full-Size Mattress

Having understood the importance of choosing the right size of the mattress, it’s equally crucial to delve into the specifics of what makes a quality mattress.

Let’s start by exploring the material and construction of a full-size mattress, which play a pivotal role in determining its comfort, durability, and overall performance.

Material and Construction

When it comes to the material and construction of a mattress, it’s all about personal preference. Some people prefer the traditional innerspring mattresses for their bounciness and firm support. Others lean towards memory foam mattresses for their pressure relief and contouring abilities. Hybrid mattresses, which combine innerspring and foam, are also a popular choice for those who want the best of both worlds.

Firmness Level

The firmness level of a mattress is crucial for your comfort and spinal alignment. If you’re a side sleeper, a soft to medium-firm mattress can provide the necessary contouring for your hips and shoulders. For back and stomach sleepers, a firmer mattress is often recommended to prevent your hips from sinking and keep your spine aligned.


The price of a full-size mattress can vary greatly depending on its material, construction, brand, and other features. On average, you can expect to pay anywhere from $250 for a budget-friendly mattress to over $1000 for a luxury model.

Trial Period and Warranty

Most mattress companies offer a trial period, allowing you to test the mattress at home for a certain period (usually 100 nights or more). If you’re not satisfied, you can return the mattress for a full refund. In addition, a good warranty (10 years or more) is a sign of the manufacturer’s confidence in their product.


Choosing the right mattress is a crucial decision that can significantly impact your sleep quality and overall health. A full-size mattress, with its perfect blend of comfort and space efficiency, can be an excellent choice for single sleepers, teenagers, and those with smaller living spaces.

However, it’s essential to consider factors such as the material and construction, firmness level, price, and the trial period and warranty offered by the manufacturer.

By doing so, you’ll be well on your way to finding a full-size mattress that provides you with restful sleep night after night.

Remember, a good day starts with a good night’s sleep, and a good night’s sleep starts with the right mattress.

What are the dimensions of a full-size mattress?

A full-size mattress, also known as a double mattress, typically measures 54 inches in width and 75 inches in length. This size is suitable for single adults and teenagers who want more sleeping space than a twin-size mattress offers.

Is a full-size mattress big enough for two people?

While a full-size mattress can technically accommodate two people, it might be a tight fit. Each person would have about 27 inches of personal space, which is less than the width of a twin bed. Therefore, it’s often recommended for single sleepers.

What is the difference between a full-size mattress and a queen-size mattress?

The main difference lies in their dimensions. A full-size mattress measures 54 inches wide by 75 inches long, while a queen-size mattress is larger, measuring 60 inches wide by 80 inches long. This extra space in a queen mattress can make a significant difference for couples or individuals who prefer more sleeping space.

How do I choose the right mattress size?

Choosing the right mattress size depends on several factors including the size of your bedroom, your sleeping habits, whether you sleep alone or with a partner, and your budget. For single adults or those with smaller bedrooms, a full-size mattress can be a great choice. However, couples or those who like more space might prefer a queen or king-size mattress.

What are the top-rated full-size mattresses?

The top-rated full-size mattresses vary based on individual preferences for material, firmness, and other features. However, some consistently high-rated options include the Nectar mattress, Saatva Classic Mattress, and the Helix Midnight mattress. Always consider factors like comfort, support, durability, and price when choosing a mattress.
