Often those restricted by a budget will purchase a new mattress too small with the thought of saving money or that they will have enough room to sleep comfortably. College students, single adults, and parents with growing children buy twin size mattresses, not realizing they need the additional 5-inch length twin XL mattresses offer.

In this article, we’ll discuss our recommended twin XL mattresses. We’ll also explore what to consider when buying a twin XL bed, including who the mattress is intended for, budget, and mattress materials and firmness.

How Big Is a Twin XL Bed?

The twin XL mattress is the second smallest mattress size—third, if you’re counting the crib beds. It has a 38-inch width and 80-inch length, which is 5 inches longer than the twin mattress to accommodate taller children or single adults.

The twin XL mattress is a great mattress for those single adults or children who don’t need a lot of sleeping space and want more floor space in their bedroom. It’s also a good budget mattress, as twin XL mattresses don’t use as many materials to construct, which keeps the price low.

Best Twin XL Size Mattress Buying Guide

Your sleep needs influence the mattress size you will need. Your budget and plans for the bed can also affect the mattress size you will buy.

Who Are You Buying For

If you’re buying the mattress for yourself, consider your height, your body type, and whether or not you have a sleeping partner when choosing a mattress size.

If you don’t have a sleeping partner, you don’t have to consider their sleeping needs and can focus on your own. If you’re over 6 feet tall, we recommend purchasing a twin XL to accommodate your height and prevent your feet from dangling over the bed’s side.

Twin XL mattresses are great for college dorm rooms. They can also work for a guest room.

Those with sleeping partners want to purchase a queen size mattress. You will want to consider your partner’s height when choosing a mattress size.


While the mattress’s brand influences the price, the bed’s cost goes up if you purchase a larger mattress size. If you’re on a budget, you want to buy a larger bed size to promote restful sleep, but small enough to limit your expenses.

For instance, a 23-year-old male college student with a 6-foot and 3-inch height and weight around 167 pounds will want to purchase a twin XL mattress. A twin XL is long enough to accommodate persons height up to 6 feet and 7 inches. The twin XL will also offer enough room for the college student to change sleeping positions without falling off the bed.

Creating a Split King Mattress

Split king mattresses have the same dimensions of two twin XL mattresses placed side by side. A split king mattress allows a couple to have two firmnesses for those couples with different sleep preferences.

If you have a twin XL mattress you love, but your partner needs another firmness, you can purchase a twin XL mattress catering to their preferences. Push the two beds together to create a split-king bed.

Mattress Materials

If you’re looking for a certain feel, looking into the type of mattress will set you on the right path.

Innerspring Mattress

Innerspring mattresses are made with coil support cores and thin comfort layers made of polyester, cotton, and wool. Some innerspring beds have Euro and pillow tops that serve as a plush comfort layer.

The coil system encourages air circulation to wick away heat, making the coil bed one of the most cooling mattresses on the market.

Memory Foam Mattress

Memory foam mattresses are made with at least one memory foam layer. They are very supportive and conforming.

Memory foam is a type of elastic polymer. It reacts slowly to pressure and bounces back slowly when pressure is removed from the material’s surface. This slow reaction to pressure allows the material to contour closely to the sleeper to alleviate pressure and pain.

Plant-based memory foam is a type of memory foam manufactured by substituting soy oils and other plant materials for some petrochemicals, which creates a breathable, eco-friendly foam.

Gel, copper, and graphite-infused memory foam pull heat from the sleeper to offer a cooler sleep surface. The conductive properties allow the heat to pass through the materials without retaining it.

Latex Mattress

There are several types of latex mattresses. All of them are very supportive and conformable; however, depending on your environmental outlook, health, and budget, you might prefer one type of latex mattress over the other.

Natural latex mattresses are made with rubber tree sap. They are antimicrobial and hypoallergenic. Natural latex is made in two ways, although we won’t recommend either option to someone with latex allergies.

The Dunlop process produces a firm, dense latex foam. It’s made without chemical additives, making Dunlop latex the only all-natural latex.

The Talalay process involves adding chemicals to the rubber tree sap to produce a light and bouncy foam.

Synthetic latex mattresses are made with a chemical compound, which makes it a great option for latex allergy sufferers. While synthetic latex mimics the feel of true latex, synthetic latex does not have antimicrobial qualities.

Blended latex is a mixture of natural and synthetic latex. It has some antimicrobial properties and is cheaper than natural latex.

We do not suggest buying a latex mattress with synthetic materials; however, if you decide to purchase one, make sure the product is CertiPUR-US® certified to ensure it doesn’t contain harmful additives.

Hybrid Mattress

Hybrid mattresses are constructed with coil support cores and memory foam comfort layers. Hybrids are cooler than memory foam mattresses, but can still retain heat due to the memory foam layers.

Hybrid mattresses have great support and conformability. They’re ideal for side and back sleepers for their enhanced pressure relief and ability to promote spinal alignment.

Sleep Trials, Return Policies, and Warranties

Sleep trials, return policies, and warranties play a large part in customer satisfaction.

These policies are offered to protect the buyer from a defective product or from keeping something we do not want.

Return Policy

The return policy outlines what you and the company’s responsibilities are when making a product return. We suggest looking for a company that bears full financial responsibility, including transportation, donation, and restocking fees.

Sleep Trial

Many of the best mattress companies offer extended home trials so the customer can decide if the mattress caters to their sleep needs. If the mattress doesn’t meet the buyer’s expectations, they may return the bed within the trial period.


Warranties ensure the company will replace or repair a mattress with defective materials or craftsmanship not incurred by the owner.

Warranties usually cover split or cracking foam, faulty covers, and sagging.

Look for a company that offers full coverage for at least 10 years, including responsibility for transportation and handling fees.

What Is Your Perfect Firmness

After you decide on the mattress type you want, you should learn which firmness improves your sleep quality. Twin XL mattresses come in every firmness imaginable: soft, medium-soft, medium, medium-firm, and firm.

One of the most effective ways to find your perfect firmness is by considering your sleep position and body type.

Your Sleep Position

Side sleepers need a soft bed to relieve pressure points that build up from sleeping on their sides the entire night. The best mattresses for side sleepers are medium in firmness as these beds offer an even balance of comfort and support to alleviate pressure and prevent joint and lower back pain.

Back sleepers need a medium to medium-firm mattress to promote spinal alignment and prevent back pain. A plush bed will cause a back sleeper’s hips to bow into the mattress and misalign the spine, leading to chronic pain. A medium to medium-firm mattress prevents the hips from bowing while contouring to alleviate pressure points in the hips and shoulders.

Stomach sleepers overextend their backs and can suffer from chronic pain more than other sleepers.

We suggest switching to side sleeping to promote healthy, restful sleep; however, if you cannot switch to another sleeping position, we recommend a medium-firm to firm mattress to preserve the spine’s natural curvature. Try sleeping without a head pillow and, instead, place the pillow under your hips to improve alignment.

Your Body Type

The pressure you place on the mattress can change its feel.

Heavy individuals place more pressure on a mattress’s surface than a small person. On a soft mattress, a large statured person will sink into the bed at the hips and shoulders, causing the spine to misalign. Firm mattresses can support larger sleepers to maintain spinal alignment.

Lighter sleepers need a soft mattress as they do not have enough weight to sink into firm materials. Softer beds alleviate pressure while offering support. A firm mattress will only create pressure points.


Can I use regular twin bedding on a twin XL mattress?

We recommend checking the dimensions of the sheet set before buying, as some twin bed sheets can accommodate a standard twin and twin XL mattress, but some don’t.

Will the purchase of a twin XL mattress require a new bed frame?

If you have an adjustable bed frame, you shouldn’t purchase a new bed frame. If the bed frame is static, you will need to find a larger frame as well as a new box spring.


When looking for a Twin XL mattress, remember your sleep needs, such as your sleeping position and body type. We suggest looking into the companies warranty, sleep trial, and return policy as it will keep you from purchasing a low-quality bed.
