The Best Twin XL Mattress of 2026

UPDATED

To get comfortable at bedtime, it’s nice to have space to stretch out and settle in. While a standard twin mattress can feel cramped, a twin XL mattress offers a roomier feel.

A twin XL is 5 inches longer, making it particularly appealing to sleepers over 6 feet tall. At the same time, a twin XL’s compact footprint of 38 inches by 80 inches can still fit in smaller bedrooms. To simplify your shopping, the experts on our testing team evaluated dozens of options to identify the best twin XL mattresses.

To see all the top mattresses, check out the best mattresses of 2025. If you don’t need the length of a twin XL, take a look at our guide to the best twin mattress.

Measuring 5 inches longer than a standard twin, the twin XL mattress is ideal for single sleepers who need a little extra legroom. Growing children and teens may also prefer the twin XL, and some bunk beds are designed with this size in mind.

Who Should Sleep on a Twin XL Mattress?

A twin XL mattress is a solid option for anyone who doesn’t share their bed and wants extra space compared to a traditional twin. With 5 inches of added length, a twin XL can better accommodate taller sleepers. 

Buying a twin XL is an affordable way to have a roomier mattress that can still fit in smaller spaces. Some of the people who are best suited to a twin XL mattress include: 

  • People over 6 feet tall
  • Sleepers who tend to stretch out in bed
  • Teens, college students, and others who want a bigger mattress but whose budgets or bedroom space may be limited

By contrast, a twin XL is not a good fit for couples, because the width of the mattress makes it hard for two people to share the bed and have enough room. Shoppers who have the space and budget to afford a larger mattress usually prefer a full or queen over a twin XL.

Twin vs. Twin XL vs. Full Size Mattresses

Twin and twin XL mattresses both have a width of 38 inches. The difference is that a twin XL is five inches longer than a twin, measuring 80 inches in length instead of 75 inches. 

A full mattress has the same 75-inch length as a traditional twin. But at 54 inches wide, a full is 18 inches wider than both a twin and twin XL. 

For couples, a twin or twin XL rarely offers enough width, making it necessary to upgrade to a full mattress. For most individual sleepers, a twin or twin XL has enough width, but the added length of a twin XL may be important for people over 6 feet tall and those who extend their arms and legs at night.

Twin XL 38″ x 80″
Full 54″ x 75″

What to Consider in a Twin XL Mattress

When choosing a twin XL mattress, important considerations include mattress type, firmness level, spinal support, and edge support.

Mattress Type

Twin XL is one of the standard mattress sizes, which means that you’ll have extensive options, including models of each mattress type. 

Mattress types are determined by the materials inside the mattress. Performance and features are driven by these materials. All-foam beds tend to have more cushioning, while latex and innerspring beds have more bounce. Hybrid models typically strike a balance by combining metal coils and other materials. Airbeds can have their firmness levels adjusted at any time.

As you start shopping, think about your preferences and sleep needs. Then, narrow down your list to only the mattress types that best meet your requirements.

Firmness and Support

Keeping your spine aligned in a neutral position can help you avoid aches and pains. Your mattress plays a key role in supporting your body in a healthy spinal posture as you sleep. 

Spinal support is closely related to mattress firmness, which is how hard or soft the bed feels. The right firmness level means you won’t sag too far into the bed or feel like you’re sleeping on a hard surface. 

To find the right mattress firmness level for you, consider your subjective preferences as well as your sleeping position and body weight. You may need a firmer mattress if you sleep on your stomach or back, or if you weigh over 230 pounds. If you are a side sleeper or weigh under 130 pounds, a softer or mid-range firmness level may be better suited to your needs.

Edge Support

Edge support describes the stability of the perimeter of the mattress. Poor edge support can mean bothersome sagging when sitting or lying near the edge of the bed. 

Since a twin XL is only 38 inches wide, quality edge support can be important, because it allows for use of the full surface of the bed.
