What is a Twin XL Size Mattress?

A twin XL mattress is the second-smallest mattress size for older children and adults. At 38” wide and 80” long, twin XL mattresses are the same width as twin mattresses and the same length as queen-size and king-size mattresses. With a narrow width and long length, extra-long twin mattresses are designed for single, tall sleepers.

Twin Bed vs Twin XL Bed

After a crib mattress, most children graduate to the twin-size bed. Twin mattresses measure 38” wide by 75” long. Twin XL mattresses are the same width as the standard twin, but 5” longer. This added length makes twin XL mattresses suitable for people taller than 6”.

Benefits of a Twin XL

Twin XL mattresses are thin and long. As such, they fit easily into small rooms, like dorm rooms, studio apartments, or guest rooms. Their narrow width is best suited for children or light-to-average weight adults who do not need much shoulder room. 

College Dorm Room

Twin XL is the standard size for college dorm beds, ensuring that even tall sleepers have adequate foot space. Because dorm rooms are notoriously small, a twin XL provides a good balance between sleeping room and floor space. 

Height

Twin XL beds are longer than either twin-size or full-size beds. Only queen size beds and larger are as long as a twin XL. Because queen and king mattresses are much larger and more expensive than twin XL mattresses, the extra-long twin is a popular choice for tall people who sleep on their own. 

Guest Room

In most homes, the smallest room is saved for the guest bedroom. And for some families, the guest bedroom doubles as a space to store large items, like suitcases or winter clothing. As such, guest beds often need to fit into small spaces. 

Because twin XL mattresses are narrow and tall, they are a good space saver. Their length makes them long enough for adult visitors, while their width allows them to fit into small spaces. 

Mattress Type

Memory Foam Mattress

Memory foam mattresses are made using a plush foam that responds to body heat. Memory foam beds offer great pressure relief, making them a good choice for side sleepers and adults with aches and pains. 

Another benefit to foam beds is that there are plenty of high-quality, low-cost bed-in-a-box options. These mattresses can be shipped directly to a college student’s dorm, making the moving process easier.  

Innerspring Mattress

Innerspring mattresses are those made using an inner-core of coils that deliver a bouncy, supportive feel. Most spring mattresses are medium-firm or firmer, delivering the right support for back and stomach sleepers. Because coil mattresses are incredibly breathable, they help hot sleepers sleep cool. 

Hybrid Mattress

Hybrid mattresses are created using a combination of innersprings and foam or latex layers. With one or more comfort layers above the innerspring coils, hybrid mattresses cushion pressure points better than traditional innerspring mattresses. Their firm yet plush support makes hybrid beds a good option for every sleeping position. 

Hybrid mattresses are usually more expensive than all-foam or spring mattresses. As such, they are best for those planning to keep their mattress for years to come. 

Twin XL Mattress Accessories

There are certain mattress accessories that help to boost comfort and longevity of twin XL mattresses. 

Twin XL Mattress Topper

Mattress toppers are an affordable way to make an extra-long twin mattress more comfortable. If you already have a twin XL mattress that could use a bit more cushion, a simple memory foam topper can completely change the feel of the bed. Mattress toppers are often purchased for existing dorm beds to cheaply add comfort and support for those who need it. 

Twin XL Mattress Pad

Mattress pads are a thinner version of a mattress topper. While mattress pads can offer minimal cushion, their primary purpose is to protect a mattress. 

Waterproof toppers, in particular, are a great addition for twin XL beds. They can protect a mattress from accidental spills or other damage that are common in dorm rooms and guest bedrooms.
