Is a Full Size Mattress Right For Me?

The full size mattress is the same length as a twin but is 16 inches wider.

The full is an ideal option for single sleepers wanting more space to move around in bed.

As a general rule of thumb, your bedroom space should be at least 9 x 9 1/2 feet to provide plenty of space.

How Big Is a Full Size Mattress?

A full size mattress (also called a double mattress) measures 54 x 75 inches. These measurements are standard throughout the mattress industry. A full size bed is the same length as a twin bed but 16 inches wider, which is ideal for a teen or adult.

All full size bed dimensions are the same length and width, though the height of a full mattress can vary. Most mattresses range from 8-14 inches tall. Some mattresses are even taller, but keep in mind that thicker mattresses aren’t necessarily better—it’s what’s inside that counts.

Can a full size mattress fit a couple?

A full size mattress used to be the standard mattress for couples, but these days it’s considered to be a bit small. A full size mattress is only 54 inches wide, which leaves each sleeper just over 2 feet of wiggle room. That’s not very much, especially for larger folks. For that reason, the queen mattress has become the new standard for couples. If you’re both average to petite in size (or especially fond of cuddling), then a full bed may be fine.

Purple mattresses are especially good for couples. The Purple Grid™ comfort layer found on all Purple mattresses has adaptive firmness, so it can provide no-pressure support regardless of body type or sleep position. Even if you and your partner prefer drastically different mattress types, you can both get a great night’s sleep on a Purple.

If you’d like to try a Purple in person, you can visit one of our partner stores across the United States. Search for a mattress store to find a location near you.

Do I need a box spring with my full mattress?

No, you don’t need a box spring with your full mattress. In fact, we don’t recommend it. Purple Mattresses are best supported by a bed frame or foundation and not a box spring. We offer a line of sturdy and attractive bed frames that are made to suit Purple mattresses perfectly.

Note: Be sure to check your mattress warranty. Some warranties require the use of a specific type of mattress base or bed frame. If you don’t adhere to the guidelines, you risk voiding your warranty. 

Is a full size mattress the same as queen?

No, a full size mattress is not the same as a queen mattress. Let’s take a look at queen and full size mattress dimensions to compare:

Full mattress: 54 x 75 inches
Queen mattress: 60 x 80 inches

The queen bed size is 5 inches longer and 6 inches wider than a full bed. For this reason, the queen bed is a popular mattress for couples and a full size bed is generally recommended for a single adult or teen sleeper.

Why did the full bed get replaced by the queen bed in popularity?

There are a few reasons. First, American bedrooms and homes have become larger over time. With bigger spaces to fill, people have opted for larger beds that give them more space to sleep. The queen's extra space makes it easier to change positions, and the extra distance between sleepers can help the bed stay cooler.

These days, we use our beds for more than sleeping. A study found that while Americans only sleep about 7 hours per night, they spend an additional 4 hours each day in bed doing other things like watching shows and scrolling on their phones. Now that the bed has become a space for activities, it’s only natural that people want to upgrade to a larger size.

But the queen’s reign may soon be over. The king mattress and California king mattress are also popular choices for the master bedroom. King size mattresses offer even more sleeping space, which is especially helpful for accommodating children and pets.
