Best Twin XL Size Mattress (2024): Reviews and Buyer’s Guide

You’ve found the perfect mattress, and now you need to decide on the right size. With so many different mattress sizes, why choose the best twin XL mattress? Answer: Convenience. The best twin XL mattresses fit any living space, whether it’s for a child’s bedroom, guest room, or studio apartment.

Twin XL mattresses typically cost less than other bed sizes and are easier to move. We share our favorite models to help you find the best twin XL mattress.

The AS3 is Amerisleep’s most popular mattress model and for good reason. The AS3 has been featured in Allure as one of the best online mattresses. The medium feel of the AS3 mattress is the perfect choice for side and combination sleepers. Responsive foams feel just right—not too soft or too firm.

The Amerisleep AS3 mattress includes a 100-night sleep trial and a 20-year warranty.

How Lying Down Feels

Amerisleep’s proprietary foam, Bio-Pur®, makes up the top layer of the AS3 and provides plush comfort that contours to the body. Traditional foam tends to trap heat and can also give off a harsh chemical smell.

Thanks to how well the Bio-Pur® conforms under the body, reviewers say how they almost never notice their partner shifting or getting out of bed at night. An extremely helpful feature in a king size mattress meant for two to share.

People who chose the Amerisleep AS3 for their Twin XL mattress love it with some minor concerns. Everyone rated it 4 or 5 stars:

Ana G: The AS3 hybrid offers good support whilst sleeping on your back and side. We bought 2 twin XL mattressesfor our king base to minimize motion transfer but didn’t love the gap between the two mattresses as they didn’t perfectly match up, so we ended up getting a king instead.

George the Farmer: I’ve slept on the twin xl for about 3 months. It is so much better than my iSerta cloud, which developed quite a dip in the middle over 3 years time. This Amerisleep mattress has loosened up and gotten softer. It concerns me a bit that a dip will happen in this mattress sooner rather than later. If the support holds up, I will continue to be very pleased with this mattress.

Chuck: Bought a pair of twin XL mattresses and a pair of twin XL mattress adjustable bases. So far the bed is very comfortable, but can be quite warm as compared to our former inner spring mattress.

Inside the Mattress

Bio-Pur® is plant-based memory foam. Manufacturers partially replace petroleum with castor oil partially, producing a responsive and breathable foam. We love how Bio-Pur® conforms to the body, relieving pressure points. Customers won’t feel stuck inside the mattress.

Affinity is a cloud-like transition foam that incorporates HIVE® technology. Hundreds of hexagonal-shaped segments form five zones of support. Areas under the shoulders and hips feel softer, while areas under the head, back, and legs feel firmer. HIVE® technology provides even pressure relief throughout the body.

The Amerisleep AS3’s base foam is Bio-Core®. This durable material distributes body weight across the surface and supports the body.

While more expensive, there’s a reason why the Amerisleep AS5 Hybrid is one of our favorites. The AS5 Hybrid is Amerisleep’s softest hybrid model. Most soft mattresses are more expensive because they contain more padding.

Responsive foams and zoned pocketed coils create a plush surface without sacrificing support. Similar models have higher price tags compared to the AS5 Hybrid.

The Amerisleep AS5 Hybrid comes with a 100-night sleep trial and a 20-year warranty.

How Lying Down Feels

Though it’s rated as a soft mattress, the AS5 Hybrid is quite capable of feeling strongly supportive. “Good support” is the second most recurring bit of praise in consumer reviews, with only “comfortable” showing up in more reviews.

Mattress owners also note that the AS5 holds its shape well, so you don’t have to worry about body impressions lingering on the soft surface. Its responsive feel ensures the cushion snaps quickly back into its original form.

Those who purchased AS5 twin and twin XL mattresses love them. Here are some of the customer reviews:

Teri: We have two twin XL mattresses in a king frame. They are amazingly comfortable, and allow for each of us to move independently without waking the other person up. We are very happy with our new purchase. It is great in terms of temperature and responsiveness. No smell, and easy to set up as well. The best part of all of this, is that they have the top customer service in the industry.

Lisa: The best bed I’ve ever slept in!!! I have I have 6 of them and won’t buy anything else.

Angela S: My hubby and I both ordered the AS5 split twin XL mattresses, and while this bed is clearly of high quality, he adjusted better to its softness than I did. He is large framed and I am of average weight; we are both back/side combo sleepers. I feel that I needed more support than it offered.

Inside the Mattress

Plant-based Bio-Pur® is more breathable than traditional memory foam. Customers will enjoy how Bio-Pur® contours to the body without trapping heat. Bio-Pur® emits less off-gassing odor, a chemical smell stronger in traditional memory foam.

Highly-responsive Active Flex instantly reacts to shifting weight, maintaining support without losing softness. Customers can rest easy without having to worry about feeling stuck inside the bed. Sinking too deep is a common problem with soft mattresses.

Sturdy zoned pocketed coils make up the support layer of the Amerisleep AS5 Hybrid. They ensure your spine stays aligned while you sleep but also prevent sagging over the years.

The Amerisleep AS5 Hybrid comes with a 100-night sleep trial and a 20-year warranty.

Next on our list is the Zoma Start Mattress, a memory foam mattress for athletes who want a twin XL mattress. We like the Zoma to silence snoring because it’s built with Triangulex™ technology to promote healthy sleeping positions.

The Zoma Mattress stands 11 inches tall and has three carefully-crafted layers. While the Zoma is built to feel medium, some reviews mention it feels medium-soft; so it’s on the softer side of the firmness scale.

Every Zoma mattress comes with a 100-night sleep trial and a 10-year warranty.

How Lying Down Feels

Lying down on the Zoma Start, the first thing you’ll notice is that it is cooling and highly responsive for an all-foam mattress. This is all thanks to the layer of bouncy Reactiv™ transition foam that springs back as soon as you move and offers dynamic support.

This medium mattress also offers tons of versatility for all kinds of sleepers. It is on the more supportive end of a medium feel. So it can accommodate some back sleepers and virtually all combo sleepers at once. This is perfect for combo sleepers who tend to favor their backs. It also is a good fit for those who suffer from back pain.

Some of the thousands surveyed on the Zoma Start had this to say:

Parth P: It is a phenomenal mattress especially for the price!

Billy K: Kind of firm waking up with shoulder pain occasionally

Xiao C: It’s of good quality overall. Came with proper packaging and easy to set up. It was a bit too soft for my back the first night, but after that I experience no back pain sleeping on it.

Inside the Mattress

The Zoma Start starts off with a cooling, ventilated cover that breathes all night to wick away heat and sweat. This cover works with the gel memory foam comfort layer to ensure your sleep surface stays cool all night. The gel memory foam also offers a high degree of compression and pressure relief to ensure you get the contouring you need.

Underneath the comfort layer, you’ll find a bouncy transition layer made of Reactiv™ foam. This layer offers buoyancy and dynamic support. It also springs back as soon as you move to ensure that the sleep surface does not have issues with body impressions or slow response time.

Finally, a layer of highly durable base foam ensures there is no sinkage in this mattress. It keeps you lifted onto the sleep surface and provides total spinal alignment. Best of all, this base foam layer increases the durability of the entire mattress.

You can expect it to fight sagging and soft spot development for at least 10 years. That means it will last just as long as many more expensive mattresses.

The Zoma Hybrid is an excellent choice for active people who want a bouncy mattress. The foams and supportive coils strike a comfortable balance that can help you sleep without disturbances.

Every Zoma Hybrid includes a 100-night sleep trial and a 10-year warranty.

How Lying Down Feels

As a medium mattress, the Zoma Hybrid is excellent for side and combo sleepers looking to alleviate pain. Customer reviews agree that whether you’re an athlete or not, the Zoma Hybrid mattress will cradle your body’s curves, support your back, and improve your sleep.

Most reviewers love the Zoma. Here is what some have to say:

Evonne B: This is my second zoma mattress. I bought a queen size a few years ago and this time I bought a king size. It’s so comfortable.

Jason D: Best mattress I’ve had to date. Took a chance on it after doing some research and really surprised. So comfortable for my preferences.

Dona F: The bed is so comfortable! My son is very tall and it’s a great fit! The delivery was fast! I’m going to purchase 2 more beds in the near future!

Inside the Mattress

We enjoy the cushiony support in the bed’s top gel foam layer. Unlike standard foam, gel-infused foam dissipates body heat so you never wake up feeling sweaty.

The next layer is Reactiv™ foam, a buoyant material that adapts to your movements. Reactiv™ prevents you from feeling stuck in a mattress that’s slow to respond.

The mattress’s support comes from pocketed coils on a durable foam base. The coils are individually wrapped to improve motion isolation. The packets around each coil also keep the coils from getting too noisy.

The Vaya Mattress is a budget-friendly option, containing high-quality materials for a low cost. Plush, responsive foam layers enveloped in soft, breathable material are a steal at $449 for a twin XL mattress. The medium feel is soft in the shoulders and hips but gives needed support to the spine.

The Vaya Mattress includes a 100-night sleep trial and a 10-year warranty.

How Lying Down Feels

The Vaya Hybrid mattress conforms under your body’s curves without causing you to sink too much into your bed, which can make switching positions and getting in and out of bed difficult. Real Vaya Hybrid users describe the bed as being soft but supportive and nice for people who share a bed, as they don’t notice their restless partners moving at night.

People tend to love the Vaya Mattress, some people have had issues with delivery, however.

Ceyatano A: Bought a Hybrid mattress which is good but never received the free pillows clearly listed on the Hybrid mattress page.

Lisa S: Last night was my first night sleeping on the Vaya Hybrid twin XL mattress, and wow I’m so glad I did my research and chose this bed!!

Sharon R: I am absolutely elated with my hybrid Vaya and those pillows are heaven. My two daughters and granddaughter also have Vaya mattresses. I can’t rave about my bed more.

Inside the Mattress

We like how Vaya Comfort foam conforms to the body and relieves pressure points. Sleepers won’t feel stuck in the mattress. Plus, this responsive foam is more breathable than traditional memory foam. It won’t trap heat and disrupt sleep.

Vaya Support foam is designed to last for years, as reflected in its 10-year warranty. Customers won’t have to worry about premature sagging.

The perimeter of this base is also reinforced with edge support for added durability and motion isolation. Couples with different sleep schedules won’t have to worry about disturbing their partner on this stable and supportive base.

If you want a 12-inch memory foam mattress that boasts the ultimate cooling power, say hello to the Nolah Signature 12. This mattress boasts several cooling technologies to keep even the hottest sleepers cool.

How Lying Down Feels

The first thing you’ll notice about this mattress is just how cool it is. It boasts multiple cooling technologies like AirFoam™ and a cooling cotton cover to both draw heat away from you and keep the cool air flowing all at once.

While some people have issues with firmness, most people we surveyed are very happy with the Nolah:

Anna G: At first I loved it but now I think it’s a little too hard and not as soft as I was hoping it would be

Rory: When I first climbed onto the mattress, my elbow went down into it and I thought, yikes this is going to be too soft. But as soon as I lay down full, I could feel just the right amount of support.

Patti D: Love my new memory foam mattress, the service was fabulous and I have no complaints, would definitely shop from Nolah again.

Inside the Mattress

The first layer of the Signature is the plush and breathable AirFoam™ that relieves pressure and keeps the cool air flowing.

Supporting the plush comfort layer are two layers of high-resilience and high-firmness transition foam. These layers keep the top layer buoyant and also protect you from pressure from the ultra-firm support core.

Finally, a layer of high-density core foam ensures that your mattress will stay sag and soft spot-free for many years. That’s why it sports a lifetime warranty!

The Nest Bedding Quail Love & Sleep mattress is available in two firmness options: medium or firm. Both come with the same $599 price tag. The medium produces deeper compression in the shoulders for side and combination sleepers. Back and stomach sleepers need heightened support along the spine to prevent sinking.

The Nest Bedding Quail Love & Sleep mattress comes with a 365-night sleep trial and a lifetime warranty.

How Lying Down Feels

Both medium and firm are excellent options for back sleepers, because the surface conforms to your body, but keeps you resting on top of the bed. Either way, you’ll like the soft, yet supportive feel of the Nest Quail Mattress.

While no reviewers mentioned the twin XL mattresses specifically, several people who bought the Nest Quail have offered their thoughts on the twin mattress:

Gretchen M: We purchased 2 twins and put them together for a king size. This works great and these mattresses are the most comfortable I’ve ever owned!

Bella: My parents got me a twin size version of this mattress for college and I loved it. It was the most comfortable mattress I’ve ever slept on and all my friends always said I had the best mattress ever. It was so soft and I felt like I sank in just enough to be comfortable. Flash forward to now and my husband and I decided to get this same mattress in a queen and it’s so firm and hard. 

MV: We bought one of these for ourselves (queen medium) and one for our kid (twin medium). The mattresses are super comfortable and I’m so glad to know they’re green guard gold certified. The price is great too.

Inside the Mattress

Energex Cooling Comfort is a unique gel memory foam infused with minerals. This comfort layer is designed to pull heat away from the body. Hot sleepers can rest comfortably without night sweats. The cushioning feel of gel memory foam also relieves pressure points.

SmartFlow Air Foam has a convoluted structure. This allows hot air to escape while pulling cooler air into the mattress.

Customers feel better supported by the Edge Support Base. This high-density foam layer includes reinforced edges. Sleepers won’t have to worry about falling off the bed at night.

The medium-firm surface of the Live & Sleep Classic Mattress may provide comfort to a variety of sleepers. The bed is soft enough for side sleepers who need deep pressure relief in the hip and shoulder areas. Stomach and back sleepers may appreciate the extra support to the lower back.

How Lying Down Feels

Of all three of Live & Sleep’s mattresses, the Classic Mattress has a balanced feel at a great price. The Classic Mattress is L&S’s most simple, affordable bed and it has a medium-firm feel, while the Elite Mattress has a firm feel.

Customers who bought the Live and Sleep twin mattress are happy with this mattress, with almost every review being 5 stars:

Quinn N: It’s good to know my child is sleeping well on this mattress made with natural materials. It didn’t take more than a day for the mattress to puff up so it fit in her twin bed frame. Now I want to sleep in her bed! Thinking of purchasing a Live and Sleep for my room too!

Hannah J: We purchased two full-sized classic mattresses for the bunk beds in our mountain cabin after having purchased a queen sized mattress for ourselves. Our adult children were so happy we bought them such a high quality and organic mattress. They slept on them for the first time this weekend and said they never slept better.

Cheryl D: We bought this mattress to transition our toddler from crib to full sized bed. After researching tons of companies and reading horror stories of fiberglass or bugs found in other mattresses, we understood the importance of a quality product. The purchase was easy, shipping was fast and the bed filled out quickly. Very comfortable.

Inside the Mattress

The thick comfort layer is made from quality memory foam. It won’t break down quickly, unlike other low-density foams. Cool and responsive memory foam relieves pressure points with little risk of overheating. Sleepers won’t feel trapped inside the mattress.

The high-density base foam enhances the contouring properties of the top layer. It also supports the body without sagging.

The Live & Sleep Classic Mattress includes a 30-night sleep trial and a 20-year warranty.

Best Twin XL Size Mattresses Highlights and Comparison

What is a Twin XL Mattress?

Twin XL mattresses are five inches longer than a standard twin mattress, about 38 inches by 80 inches. Twin XL mattresses are smaller and easier to move, perfect for single adults with limited living space.

This compact size is also standard in college dorm rooms, accommodating any height. Twin XL mattresses are perfect mattresses for taller sleepers—children, teens, and single adults (read more about best mattresses for college students here).

Finding the Best Twin XL Mattress

When searching for the best mattress, have a set budget and know how much you’re willing to spend. Look at mattress type, your sleeping position and body weight, and available sleep trials, return policies, and warranties. These will help you score the best twin XL size mattress.

Budget

Customers can expect to pay as low as $500 to over $1500 for a high-quality twin XL size mattress. Cost of a mattress depends on materials and sleep technologies.

Beds with organic materials and cooling technologies will drive up the price, though shoppers can still find mattresses under $1000 with eco-friendly and cooling materials. Some customers feel it’s worth it to spend a little more for extra comfort and support.

For those on a budget, it’s essential to look for a budget mattress that still meets their needs. Doing research and shopping around can help shoppers find affordable options that don’t sacrifice comfort and support.

Additionally, sales and promotions can provide opportunities for budget-conscious shoppers to snag a high-quality mattress at a reduced cost. By staying informed and keeping an eye out for deals, customers can find a mattress that fits their budget without sacrificing quality.

Mattress Types

Memory foam, innerspring, latex, and hybrids are common mattress types. Each mattress has a unique feel. Some people like the conforming feel of memory foam. Others prefer the bounciness of an innerspring.

Each mattress type is available in different firmness levels. The right one for you depends on your sleeping position and body weight.

Memory Foam

Memory foam softens under heat and pressure, contouring close to the body. Memory foam has better pressure relief than other mattress types. It also has excellent motion isolation, keeping any movement from a sleep partner from waking you up.

A drawback to memory foam is its heat retention. Due to its dense structure, memory foam has limited air circulation. To fix this problem, many mattress manufacturers add cooling materials, like gel and plant oils, to regulate temperature and improve airflow.

A typical memory foam mattress has a memory foam comfort layer and a high-density foam support layer.

Innerspring

Innerspring mattresses rely on steel coils for comfort and support. Innersprings have exceptional bounce and edge support from steel coils. The open structure also encourages more airflow.

Drawbacks to an innerspring include very little pressure relief and motion transfer. The thin comfort layer is designed to protect the body from innerspring coils, not relieve pressure points, but adding a mattress topper may improve contouring.

An innerspring mattress contains a foam or fiberfill comfort layer (usually in a pillow-top form) and innerspring coils as a support layer.

Latex

Latex shares the same properties as memory foam—contouring, pressure relief, and motion isolation. Unlike memory foam, latex has more bounce and feels cooler.

There are two types of latex: synthetic and natural. Synthetic latex is made through a chemical process, while natural latex is derived from rubber tree sap. Natural latex may be more expensive, but it’s proven to be more durable than other mattress materials.

Generally, a latex mattress contains a latex comfort layer and either a high-density foam or latex as the support layer.

Hybrid

Manufacturers created the hybrid mattress to offer customers a bed with the best of both foam and innersprings. Hybrids combine pressure-relieving memory foam or latex with bouncy innerspring coils. A true hybrid will have a comfort layer at least 2 inches thick and a coiled support system.

Drawbacks to a hybrid mattress include overheating, less pressure relief, and motion transfer. They’re also heavy and expensive due to the combination of high-quality materials they contain.

Sleeping Position

One factor to consider when choosing the right firmness is sleeping position. How you sleep impacts how much cushioning your body needs. For example, side sleeping places more pressure on the shoulders and hips. A softer mattress reduces pressure buildup in those areas for a good night’s sleep.

Side Sleeping

Side sleeping is one of the healthiest sleeping positions. It reduces acid reflux, enables better breathing, and improves heart health. Side sleeping is also considered one of the most comfortable sleeping positions.

A drawback to side sleeping is pressure buildup in the shoulders and hips, however, placing a pillow between the knees reduces hip pressure. It can also prevent the lower back from twisting.

The best mattress for side sleepers has a soft to medium feel. The softer feel maximizes pressure relief in the shoulders and hips.

Stomach Sleeping

In contrast to side sleeping, stomach sleeping is the least healthy sleeping position. Lying on the stomach puts intense pressure on the spine, which could lead to neck strain (turning your head to the side to breathe) and back pain (gravity forces the spine’s natural curve to straighten).

A thin pillow under the hips can reduce spinal pressure for better comfort and less risk.

Stomach sleepers need a medium-firm to firm mattress to keep their body floating on top instead of inside the mattress. A bed softer than medium-firm may cause deep sinking and create more pressure points.

Back Sleeping

Back sleeping sets the body in a neutral position for natural alignment, but it may come with risks. Back sleepers may develop sleep apnea, a condition when gravity causes the tongue to fall back or soft tissue at the back of the throat to collapse, obstructing airways.

A medium to firm surface is the best mattress for back sleepers. This surface prevents the hips from sinking too deeply, which can misalign the spine.

Combination Sleeping

Combination sleepers, or restless sleepers, toss and turn each night, switching between different sleeping positions. Combination sleepers enjoy the benefits of each sleep position, including natural alignment and better heart health, but they also get all the risks, like neck strain and sleep apnea.

The best mattress for combination sleepers will have a medium to medium-firm feel. This maintains spinal alignment for each sleeping position for a balance of comfort and support.

Body Weight

Another factor to consider when choosing the right firmness is your body weight. Body weight affects how the mattress supports you. If you weigh less than 130 pounds, you need a softer bed for pressure relief. If you weigh more than 230 pounds, a firmer mattress is better for extra support. Those who weigh between 130 to 230 pounds will find a medium mattress is the perfect feel.

Lightweight

Lightweight sleepers weigh less than 130 pounds. A softer surface is better because it allows body weight to sink into the mattress for better contour and pressure relief.

Average Weight

Average weight sleepers weigh between 130 to 230 pounds. A medium mattress provides an even amount of comfort and support for a good night’s sleep.

Plus-Size

Plus-size sleepers weigh more than 230 pounds. They find the best comfort on a firmer surface to support their body weight without sagging.

Sleep Trials, Return Policies, and Warranties

Sleep trials, return policies, and warranties assure customers of a long-lasting mattress. Sleep trials and return policies let customers try and return a bed if it isn’t a good fit. Warranties cover damages that could shorten a bed’s lifespan. Avoid mattresses that don’t have a sleep trial or return policy and a warranty.

Sleep Trial

A sleep trial allows customers to try out a new mattress at home for an extended period, helpful with an online mattress you can’t try out. Most sleep trials last up to 100 nights or longer, depending on the brand.

Some companies may require customers to keep the mattress for at least 30 days to allow the body to adjust. If the customer doesn’t like the mattress, most companies issue a full refund. If a sleep trial isn’t offered, take a look at the return policy.

Return Policy

Return policies are a good substitute for a sleep trial, though they usually won’t last as long. Return policies often last no more than 30 days—about the amount of time it may take to adjust to a new bed. Should the customer not like the mattress, they can return it for a full refund.

Warranty

A warranty protects the mattress from sagging greater than 1 inch (depends on brand) and manufacturing defects that could damage the bed. Most new mattresses come with a standard 10-year warranty.

Other Mattress Sizes

If a twin XL size mattress isn’t what you’re looking for, other mattress sizes, including twin, full, queen, king, and California king, might be better options for your living space. Other sizes may accommodate more than one person.

Plus, a different mattress size may better fit a specific area, like a guest room. Some hosts may want a larger full or queen mattress for guests, for example.

Twin Size

Twin size mattresses are the next step up from a crib mattress. Twin beds are small, measuring 38 inches by 75 inches, and more convenient to transport, making them perfect for children. For families with more than one child, bunk beds are a great way to utilize space. Twin mattresses are also an excellent option for studio apartments.

Full Size

Full size mattresses, or double beds, are 54 inches by 75 inches—16 inches wider than a twin. Full beds have more room for sleepers to sprawl out, an excellent option for combination sleepers who toss and turn at night. Full mattresses are best for teenagers and single adults. Couples may find a full size too small for their tastes.

Queen Size

At 60 inches by 80 inches, the queen mattress is most popular among single sleepers. The extra room provides luxurious space to stretch out.

Queen size beds are also good choices for couples, but some couples may find this size too small and prefer a king or California king mattress instead. If you have the space for one, a queen bed is also a highly versatile mattress for a guest room.

King Size

A king size mattress is the largest standard size at 76 inches by 80 inches. King size beds are perfect for couples, offering 38 inches of personal space for each person. King mattresses fit most large master bedrooms.

This size is also available as a split option. Split king mattresses are essentially two twin XL beds put together. Split king beds offer customized comfort and support to each sleeper without compromising.

California King Size

California king size mattresses are longer and narrower than a standard king size, at 72 inches by 84 inches. Cal king beds are excellent for taller couples who need more legroom. While not as widely available, California king mattresses often come in a split option for personalized comfort and support.

FAQs

Can twin size sheets fit on a twin XL size mattress?

While twin and twin XL size mattresses have the same width, they don’t share the same length. Twin XL beds are five inches longer than a twin—an excellent option for taller sleepers. Because of their longer length, twin size sheets will fall short and not fit a twin XL bed.

What is a double bed?

A double bed is the same size as a full mattress. Double beds are 54 inches wide and 75 inches long. Double beds were considered excellent sleeping options for couples until the queen size mattress became popular in the 1950s. Today, double beds are best for single adults and too small for couples, compared to the more spacious queen, king, and California king sizes.

Do two twin beds make up a king size mattress?

No. A twin bed is only 75 inches long, five inches shorter than the 80-inch length of a king size. It’s actually two twin XLs that make up a split king. Split king mattresses are excellent options for couples with differing sleep preferences. They’re also perfect for adjustable beds—each person can elevate their body without disturbing their sleep partner.

What is the best twin XL mattress?

To put it simply, the best twin XL mattress is one that feels comfortable for you and delivers better sleep. The “best” mattress option will differ from person-to-person, but you can find a high-quality bed by merely considering how you sleep, your body type, and your preference for firmness.

How much do twin XL mattresses cost?

Twin XL mattresses cost anywhere between $500 and $1,500 depending on their materials and features. Some twin XL mattresses will cost less than $500, but we suggest avoiding any beds priced below $350 since they’re likely made of cheaper materials.

Conclusion

A twin XL size mattress is a convenient option, fitting most living spaces at a lower cost than other bed sizes. The best twin XL size mattress is the Amerisleep AS3—customers will love the breathable, yet responsive foam layers and zoned sleep technology for even pressure relief and support.
