Full extra-large (XL) mattresses have the length of a standard queen and the width of a full. The best XL full mattresses may vary based on your specific needs and budget.

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

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

Two people can share a full XL, but it will be a tight fit if you’re used to a queen or king. The full XL mattress size may work best for people who don’t sleep with a partner.

In choosing our top picks, here’s what we considered:

  • In-home trials: We prioritized brands that offer generous trial periods whenever possible since the best way to really test a mattress is to sleep on it.
  • Return policies: We checked for policies that make it easy to return a mattress if it’s just not a good fit.
  • Warranties: We looked for mattresses that come with reasonable warranties for peace of mind.
  • 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.

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.

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.

Full XL mattresses can be found in many of the same options as more traditional mattress sizes.

Memory foam

Another thing to keep in mind is that memory foam mattresses typically have an “off-gassing” smell when they’re brand new. This may bother people who are sensitive to smells, but it’ll fade after a few days.

Latex foam

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

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


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

Still, they don’t have as much motion isolation as memory foam.

Shopping for a mattress can be challenging since it’s such a personal — and in many instances expensive — purchase. Here 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 mainly 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.

Still, you can find some full XL mattresses that don’t ship compressed. In this case, the company you buy from will typically deliver and set up your mattress, and they may also haul away your old one.

No matter which route you choose, be sure to purchase from a company that allows a free sleep trial. That way, you can make sure the mattress works for you before you commit to buying it.

Sleep accessories

Keep in mind that as a nontraditional size, a full XL mattress will need a special bed frame and sheets. You won’t be able to use traditional full sheets and frames.

How big is a full XL mattress? Is an XL twin the same as a full?

A full XL mattress is 54 inches wide by 80 inches long. That’s 5 inches longer than a regular full mattress, which is 54 inches by 75 inches.

Who are full XL mattresses best suited for? How common are full XL beds?

Full XL mattresses are good for tall sleepers who need a little extra room. They usually work well for single sleepers, as well as petite people who sleep with a partner. While full XL beds aren’t the most commonly purchased mattress size, they may be a great fit for a smaller room or apartment where space is limited.

What companies make full XL mattresses?

While full XL mattresses are becoming a more common size among mattress companies, we have found that Brooklyn Bedding, Dreamfoam by Brooklyn Bedding, and My Green Mattress sell some of the best full XL mattresses on the market.

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

No, full sheets and mattress pads will not fit a full XL mattress. So if you opt for a full XL mattress, you’ll need to buy special sheets and mattress pads designed to accommodate the extra length.

Who is a full XL mattress best for?

Full XL mattresses are great space savers if you live in a small apartment and don’t need a wide bed but are tall (up to 6 feet) and need the extra length.

With so many sizes and options, finding the right mattress can be intimidating. But there may be advantages to investigating nontraditional mattress sizes like the full XL.

If extra length is particularly appealing and you’re not planning on sharing your bed, a full XL may be right for you.

Remember to make your purchase from a reputable manufacturer and check the warranty and return policy before you buy.
