Is a full size mattress right for me?
Here, we’ll break down the top considerations you need to ponder before buying a full size mattress.
Who will sleep in the bed
Because a full size mattress is only 54 inches wide, it doesn’t provide adequate space for most couples. In a full size bed, each person will only have 27 inches of space for themselves. That said, if you’re not physically large and don’t mind snuggling, it could be just fine. Additionally, because they’re not especially long, full size beds aren’t a great option for tall folks. A full size bed is just barely over 6 feet in length, so you’re looking at feet hanging over the edge of the bed if you’re a few inches over 6 feet.
Desired comfort level
For solo sleepers, take your sleep position into account—a softer mattress is ideal for side sleepers, a medium firm mattress is good for back sleepers, and a firmer mattress is best for stomach sleepers.
Your room size
If you’re working with somewhat limited space, a full mattress could be right up your alley. For example, if you live in a one-bedroom apartment with a diminutive bedroom or you’re looking to fill a kids’ bedroom, a full mattress could be a good fit. The minimum recommended room size for a full size bed is 10 x 10 feet.
“The biggest consideration is who is sleeping in it, how often, and does it suit the room?” says Prudence Bailey, founder and principal designer of Prudence Home + Design in Connecticut. “A full bed is more nimble in small room situations, and since it’s a little wider than a twin, you can run it along a wall length with a great headboard and it can serve two purposes: a bed or a sofa for lounging with friends—this is especially great in teen bedrooms.”
If you have a small bedroom with a full size bed, you may want to avoid nightstands because they take up serious real estate. A platform bed can incorporate storage, so that may be something to consider. Getting creative with wall shelving can also help maximize your space.
Your body size
While full mattresses may be good for heavier individuals, they may not provide enough space for heavier couples. (Learn about the best mattress for heavy people.)
You’ll be happy to know that full size mattresses are less expensive than their larger counterparts. For instance, full size beds are usually 10% to 15% less than queen size mattresses of the same style and brand. A full size innerspring mattress will be the most affordable type of mattress since it tends to run less expensive than other mattress types.
Whether you’re buying a full mattress or another size, if you sleep hot, you may want to skip memory foam since it can trap heat. Innerspring and latex mattresses sleep the coolest, resulting in improved sleep.
For full mattresses and beyond, a memory foam mattress is the best at reducing motion isolation, while on an innerspring mattress, you may feel yourself or your partner moving around, which can disturb sleep.
Other types of full size mattresses
Do full size mattresses come in other mattress sizes? Here, we’ll answer that question.
Full size beds and double mattresses are the same. They both measure 54 x 75 inches.
Full XL mattress
As the less common version of the full mattress, a full XL measures 54 x 80 inches. If you can track down a full XL mattress, you’ll find that it’s a great option for taller teens or adults and could work nicely in a dorm room if there’s enough space to fit it.
Full mattress vs. other mattress sizes
As you weigh the pros and cons of various mattress sizes, you can familiarize yourself with how the full mattress compares to the queen size mattress.
Full vs. queen
While a full mattress offers plenty of room to solo sleepers and a cozy situation for couples, a queen mattress provides even more space with 6 additional inches in width. A queen size mattress measures 60 x 80 inches.
A full mattress is an excellent choice for small spaces, but a queen will likely be too large and overwhelm a room. Also, full size beds are great for children, but queen mattresses will simply be too big for them.
Other mattress sizes
If you’re not completely sold on a full mattress, there are lots of other mattress options to explore. These articles will provide the information you need as you make your decision.
Full bedding sets and accessories
Once you’ve picked your full mattress, the work isn’t quite done! Next, you’ll need to think through bedding and your foundation.
- Sheets: Full sheet sets usually come with a flat sheet, a fitted sheet, and two pillowcases. For full XL mattresses, you’ll need to look for a corresponding full XL sheet set, which can be tough to find since it isn’t a standard mattress size. Try this organic percale sheet set.
- Pillows: A standard pillow will be your best option for a full size bed—they measure 20 x 26 inches. You can fit two standard pillows across a full size bed comfortably. A standard pillow will fit into a standard pillowcase. Check out this ultra-supportive latex pillow.
- Mattress protector or pad: Are you buying a full mattress for your child? In this case, we recommend purchasing a waterproof mattress protector or mattress pad to protect against accidents. Keep in mind that they’re good for adults too since they safeguard against spills, stains, and bed bugs.
- Mattress foundation: A full mattress can be paired with several foundation types—just be sure to double-check with the manufacturer to see what your mattress is compatible with. A traditional box spring foundation used to contain actual springs in a wood box, but today, it’s more of a fabric-covered or exposed wood frame that supports the mattress and creates a comfortable height for your bed. A platform bed is a modern option meant to be used without a foundation since the mattress rests directly on the platform. An adjustable bed base will work as well.
