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-size mattress, but it has the 80-inch length of a standard queen. That means there’s an extra five inches of leg room.

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

Full XL mattresses can be a little challenging to find, so we’ve assembled this list of six of the best.

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

  • 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.

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

Varying comfort levels from plush to firm are also available, and some full XL mattresses feature temperature control if you tend to sleep hot. All of these considerations should weigh into your choice of mattress.

It’s also 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.

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.

Keep in mind that while a full XL is only 6 inches narrower than a queen, it’s probably not spacious enough for you and a partner.

Another consideration is that, as a non-traditional 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.

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

If extra length is particularly appealing, and you aren’t planning on sharing your bed with anyone else, a full XL may be just right.

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