All of the mattresses listed below are available in a full xl size (54″ x 80″). If you are looking for a full xl mattress, chances are it is because the length of a full mattress is too small and the width of a queen mattress is too wide. A full xl mattress is the perfect in-between size for taller sleepers to gain the length of a queen mattress without having to give up the additional width that a queen takes up. Full xl mattresses are considered an “odd” size mattress and are more rare to find manufacturers that make them compared to standard size mattresses. Luckily there are quite a few quality manufacturers that have expanded their lines to include a full xl option. We have done all the research and have included the best full xl mattresses on the market into one easy to follow buyer’s guide. This list includes full xl mattresses that accommodate sleepers of all preferences, sizes, ages and weights. Note that some companies classify a full xl as 53″x80″ rather than 54″x80″. Either size will fit a standard full xl bed frame just fine.

What size is a Full XL mattress?

A full xl mattress measures 54” wide by 80″ long. 

Full vs Full XL Mattress:

A full xl mattress measures 54”W by 80”L. This is 5” longer than a standard full mattress which measures 54”W by 75”L. 


What is a full xl mattress used for?

Full xl mattresses are perfect for taller sleepers who prefer the 54″ width of a full but need additional length. The 80″ length of a full xl mattress gives 5″ of additional length and measures the same length as a king or queen mattress. The reason many customers choose a full xl rather than jumping up to a queen mattress is that they can save the additional 6″ of width that a queen takes up. That 6″ may not seem like a lot but when it is in a smaller room it can make a big difference. A full xl mattress is also wide enough to fit 2 sleepers if needed. 

What are the different types of full xl mattresses?

Full xl mattresses are available in a variety of different materials and comforts. This allows for customers to still be able to choose a mattress that meets their comfort and material preferences even with the customized size specs.

  • Hybrid full xl: A hybrid mattress is a fancy way of specifying that the mattress utilizes innersprings as well as foam. This gives the sleeper the traditional bounce and support of a spring mattress while also providing pressure relief and comfort properties of a foam mattress. We recommend hybrid mattresses to the large majority of sleepers who don’t have any specific sleep needs.
  • Latex full lx: Latex is known as the most “natural” option when is comes to mattress materials. Latex is poured form the rubber tree and is made without the use of harsh chemicals or additives that other products are made with. It is important to note that there are strict guidelines for mattresses in terms of chemical additives these days and many of the chemicals used in the past (such as Flame Retardant sprays) are no longer used on any mattresses.
  • Memory Foam Full xl: Memory foam has recently become very popular in the bedding market. The material was originally made for use by NASA and was ultimately used in mattresses due to its unique pressure relief and cradling properties. Memory foam has a very unique feel that some people love and others hate. If you have never tried sleeping on a memory foam mattress before it is important to note that the feeling it very different from a traditional spring mattress.

Full XL Mattress Pricing

In general a quality full xl mattress is going to run slightly more expensive than a full and slightly less than a queen. You can find an entry level affordable mattress starting around $300. A great value, quality mattress that will last years for about $800-$1000 and then a luxury mattress from $1500-$2000.

Things to consider before choosing a full xl mattress.

There are a variety of full xl mattresses on the market and it is important to think about your specific needs when choosing which may be best.

  • Usage: How often will you be sleeping on this mattress? How long will it need to last? If you plan to sleep on this mattress for multiple nights in a row or want it to last for many years we recommend staying away from the entry level affordable mattresses. These entry level mattresses are intended for occasional use and won’t hold up as well as some of the higher end mattresses.
  • Does your mattress have custom cut corners? If your mattress has custom cut corners your options will be more limited to one or 2 retailers.
  • Material: Do you prefer a specific type of feel. The comfort level of Memory foam to innerspring mattresses or latex mattresses is all very different. It is important to understand what it is you like to sleep on before choosing a mattress that is right for you.
  • Firmness: What firmness do you prefer? Many of the mattresses we provide on this list will allow you to choose a firmness or are built to accommodate the large 80% of sleepers who prefer to sleep on a medium-firm mattress.
