Full extra-long (XL) mattresses have a standard queen’s length and a full’s width. Dreamfoam makes it on our list twice. See what other brands made the cut.

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 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 (in) narrower than a queen, so it’s probably not spacious enough for you and a partner.

The full XL mattress size may work best for people who don’t sleep with a partner.

In choosing our top picks, each product went through our rigorous vetting process. Before sending it through, 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 can be found in many of the same options as more traditional mattress sizes, such as latex and foam.

Finding the right mattress for you can be challenging, as there are many options to consider before making a 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 you choose, be sure to purchase from a company that allows a 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. Instead, you’ll need a full XL bed frame and sheets designed for full XL mattresses.

Some brands offer full XL sheet sets. Here are just a few:

  • Bare Home
  • Me Sooo Comfy
  • Veria
  • Nestl

Full XL mattresses have the same width as a standard full but 5 in extra in length, measuring 54 by 80 in.

They also 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-in width of a standard full mattress, but it has the 80-in length of a standard queen. That means there’s an extra 5 in of legroom.

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

Full XL mattresses are good for tall sleepers who need a little extra room. They usually work well for single sleepers.

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.

While more mattress companies are starting to make full XL mattresses, we found that Brooklyn Bedding, Dreamfoam by Brooklyn Bedding, and My Green Mattress sell some of the best on the market.

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.

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.

Yes. An XL full bed has 5 in extra in length.

A full mattress is bigger than a twin XL in width, not length. A twin XL mattress is 38 in wide by 80 in long. A full mattress is 53 in wide by 75 in long.

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. Just remember that you’ll need a full XL bed frame and sheets to go with your new mattress. Standard full bed frames and sheets won’t fit.

Make sure your purchase comes from a reputable manufacturer and check the warranty and return policy before you buy.
