One of the challenges of finding a good mattress is finding the right size for your space. If you’re tall and considering a full mattress, a full extra long (full XL) might be a better choice.

This mattress size shares the 54-inch width of a standard full mattress, but it has the 80-inch length of a standard queen. That means there’s an extra 5 inches of legroom.

“If you are used to a queen or king, it will be difficult to share a full XL. The full mattress size is best for people who don’t sleep with a partner.”

We have put together a list of the best full-sized mattresses.

We considered what we should pick in our top picks.

  • Company policies. We looked for mattresses that come with reasonable warranties and in-home trials whenever possible.
  • Company reputation and transparency. All the mattresses on our list come from companies with positive reputations and transparent business practices.
  • Customer reviews. We reviewed feedback from customers to see how these mattresses really perform. While opinions on mattress comfort will vary, it’s still helpful to see what others think.
  • Safety. All the mattresses on our list meet federal flammability requirements.

Many of the same options as more traditional mattress sizes are available for full-sized mattresses.

Memory foam

When a mattress is brand new, it has an off-gassing smell. It will fade after a few days, even if it bother people who are sensitive to smells.

Latex foam

Latex foam mattresses can be made either from natural or synthetic latex. Natural latex is an eco-friendly option.

latex has the same pressure-relieving properties as memory foam, but it is usually springier and doesn\’t have the “sinking in” feeling that some memory foam picks do.

Innerspring

Innerspring mattresses are an older style of mattress. They’re made with steel coils and springs as the main structural component. They also have some padding on top, though this is generally fairly thin.

Hybrid

Hybrid mattresses offer a mix of cushioning foam and supportive springs. They’re a popular style that provides the best of both worlds.

“They don’t have as much motion isolation as memory foam.”

A full mattress is the same width as a full mattress, but it is slightly longer. It is only 6 inches narrower than a queen, so it is not large enough for you and a partner.

Full XL mattresses come in a range of comfort levels from plush to firm, and some full XL mattresses feature temperature control if you tend to sleep hot. All these considerations should weigh into your choice of mattress.

It can be difficult to find a mattress that is affordable and personal. There are a few things to keep in mind.

Preferred sleeping position

It’s important to choose a mattress that will accommodate your preferred sleeping position. If you’re predominately a back or stomach sleeper, a firm mattress will provide the right support. Softer mattresses are suitable for side sleepers.

Bed-in-a-box vs. traditional

Full XL mattresses often fall into the bed-in-a-box category. Most of them are compressed and shipped in a compact box. You’ll need to give the mattress time to expand to its full XL size.

“Some full-sized mattresses don’t ship compressed. If you buy from a company, they will usually deliver and set up your mattress, and they may also take your old one.”

If you choose to purchase from a company that allows a free sleep trial, you will be sure to do so. You can make sure the mattress works for you before you buy it.

Sleep accessories

“A full mattress with a bed frame and sheets will be a nontraditional size. You won’t be able to use traditional full sheets and frames.”

How big is a full XL mattress?

A full mattress is 80 inches long. A regular full mattress is 54 inches by 75 inches.

Who are full XL mattresses best suited for?

Tall sleepers who need a little extra room can benefit from full sx mattresses. They work well for single and Petite sleepers who sleep with a partner.

Will full sheets and mattress pads fit a full XL mattress?

No, full sheets and mattress pads are not compatible with a full mattress. If you want a full mattress, you need to buy special sheets and mattress pads.

Who is a full XL mattress best for?

“If you live in a small apartment and don’t need a wide bed but are tall, Full XL mattresses are great for you.”

Finding the right mattress can be difficult. There are advantages to investigating mattresses that are not the standard sizes.

“If you don’t plan on sharing your bed, a full XL may be the right size for you.”

Make your purchase from a manufacturer that has a good warranty and return policy.
