Twin is the smallest among the six standard mattress sizes. Twins offer some benefits that other mattress sizes don’t. For one, twin sizes tend to be the cheapest option for any mattress model. Twins also take up the least amount of floor space, making them suitable for people with smaller bedrooms.

Our team thoroughly tests each mattress to find the models that are most worth your money. We take comfort, support, and value into account when making these selections. Our testing team includes people across a wide span of weights and sleeper types so that we can provide thorough recommendations for readers.

Bottom Line:

Your child's mattress needs to change as they grow, and the Helix Kids' dual-sided design is a perfect solution to accommodate these ongoing needs. Our team found both sides have a nice balance of plushness and support.

The Helix Kids Mattress is a hybrid with a flippable design. With two firmness levels – one on each side – this model is intended to meet your child’s evolving firmness and support needs as they grow older.

How It Performed

Kids do not test our mattresses, but our testing process for the Helix Kids focused on factors important to how kids sleep. The mattress has medium soft (4) and medium firm (6) sides. The softer side caters to children 3 to 7 years old, an age group that fares better with plusher surfaces. The firm side is aimed at 8- to 12-year-olds, since this age group may need a firmer mattress to support their growing bodies.

Between the foam comfort layers and coil core, both sides offered a mix of support and contouring during our tests. This is ideal if your child sleeps on their side, a position that requires cradling in the shoulders and hips but also benefits from support for the lower back.

What It’s Made of

The softer side begins with a layer of memory foam that adapts to the body to relieve pressure. This layer is infused with cooling gel designed to absorb and dissipate excess body heat. Meanwhile, the firmer side features a polyfoam comfort system that has a slightly denser feel. This side ensures your child’s weight is evenly distributed across the surface without sinking too deeply. Both sides share a support core made of pocketed coils with a reinforced perimeter that prevents sinking along the edges. The cover is made of a breathable Tencel fabric, and the entire mattress has a water-repellent finish meant to protect against nighttime accidents and messy spills.

Helix provides a 100-night sleep trial for your child to test the mattress. The bed also comes with a 10-year limited warranty against structural defects. Customers in all 50 states receive free shipping with their purchases.

Sleep Foundation Exclusive Offer!

Bottom Line:

The Nectar is a solid choice if you like the feel of memory foam but usually find these mattresses too soft. It's a true medium firm, and our testers didn't feel much sinkage at all.

The Nectar Mattress stood out during our tests, thanks to its premium materials, high-quality design, and approachable pricing. The medium firm feel made it more supportive than other memory foam models we’ve tested.

How It Performed

The Nectar earned much higher marks in our edge support tests compared to other all-foam models. This prevented sagging when our testers got on and off the bed, and it added more stability when they lay near the perimeter.

The Nectar’s moderate conforming made the mattress optimal for our team’s side sleepers of any weight. These testers found that the foam cushions the shoulders and hips to align the spine and reduce pressure throughout the body. A sturdy support system also ensured comfortable contouring and minimal sinkage for our back and stomach sleepers under 230 pounds. The bed is virtually silent, as well, so you don’t need to worry about disruptive squeaks and creaks if you switch to a different sleeping position.

What It’s Made of

The Nectar starts with a memory foam comfort layer that closely contours the body to relieve pressure in the joints and lower back. Beneath that is a polyfoam transitional layer that provides gentle contouring to prevent you from sinking too deeply beneath the surface. A support core of high-density polyfoam provides pushback to your hips and shoulders to promote healthy spinal alignment.

Customers in the contiguous U.S. qualify for free ground shipping. The Nectar is backed by a 365-night sleep trial – one of the longest in the industry – and a non-prorated lifetime warranty for added peace of mind.

Mattress Type: Hybrid

Sizes: Twin, Twin XL, Full, Queen, King, California King

Who it’s best for:

  • Hot sleepers
  • People who experience pressure points


  • Plush, quilted cashmere-blend cover adds softness
  • Gel-infused memory foam comfort layer for pressure-relieving contouring
  • Lifetime warranty and 365-night sleep trial

Sleep Foundation Exclusive Offer!

25% off everything + $599 of accessories included with mattress purchase

Bottom Line:

The DreamCloud provided plush cushioning for our testers while maintaining a supportive feel with pocketed coils. These features made the mattress feel balanced.

The DreamCloud offers the feel and performance of a luxury hybrid at a budget-friendly price-point. The mixed-foam comfort system evenly contoured to our tester’s bodies without excessive sinkage. This made it a comfortable pick for a wide range of testers.

How It Performed

Thanks to the medium firm (6) feel and foam hybrid design, the DreamCloud performed well during our tests across sleeping position and weight groups. Side sleepers who weigh between 130 and 230 pounds saw the most benefit from the plush comfort system, but back and stomach sleepers also found the coils kept them on an even plane.

We also recommend the mattress for hot sleepers. The coils circulate strong air currents to help the interior stay cool, and the entire bed is encased in a breathable cashmere-blend cover. With a profile of 14 inches, the DreamCloud is much thicker than the average mattress.

What It’s Made of

The DreamCloud is constructed with a top comfort layer of polyfoam that’s quilted into the cashmere blend cover. Our testers noted this feature gave the surface a plush initial feel. Next is a gel-infused memory foam layer that closely contours to your body. A polyfoam transitional layer acts as a buffer between the comfort system and the coils. This layer also ensures even weight distribution. A support core of individually-wrapped coils offers ample pushback to your midsection to prevent uncomfortable sagging and sinkage along the perimeter. The coils rest on a polyfoam base layer for extra stability.

The DreamCloud is a high-value model, given its high-end design and strong performance across different categories. Shipping is free within the contiguous U.S. The mattress is backed by a 365-night sleep trial and a lifetime warranty, both of which are much longer than average.

Bottom Line:

The side sleepers on our team loved the close contouring from the Nolah Signature 12. The foam layers relieved their pressure points without excessive sinkage.

Side sleepers often experience pressure buildup in their joints because of the weight they put on their side. The Nolah Signature 12 combats pressure buildup with an all-foam construction and a medium (5) feel, which allowed our team’s side sleepers to sink into the mattress comfortably.

How It Performed

Our side-sleeping testers under 130 pounds felt most comfortable on the Signature 12, but side sleepers in other weight categories also felt comfortable and supported. During our testing, the mattress absorbed most movement transfer and noise. This makes it a great choice if you tend to switch positions at night. Compared to other all-foam models, the mattress performed well during our temperature control tests. This is largely to do the use of denser polyfoam layers and a breathable cover that reduces heat buildup on the surface.

What It’s Made of

The mattress’ construction starts with proprietary AirFoam polyfoam that closely contours to your body. This foam is engineered to provide extra breathability and limit heat buildup. Next is a denser polyfoam layer that prevents you from sinking too deeply into the mattress, and a firmer transitional layer of AirFoam that ensures your weight is evenly distributed across the mattress surface. The support core features high-density polyfoam that limits sagging in your midsection. A cover made from breathable organic cotton encases the mattress.

Nolah ships free to customers in the contiguous U.S. Mattress purchases come with 120-night sleep trials, during which you can return the mattress after a 30-night break-in period. If you decide to keep the Nolah Signature, it is backed by a lifetime warranty.

  • Adaptive comfort layers cushion the body while maintaining even support

Bottom Line:

The WinkBed’s robust hybrid design excels at overall support, and you can choose from four firmness levels to meet your needs. The mattress also performed exceptionally well during our temperature control and edge support tests.

If you live with chronic or frequent back pain, you should invest in a mattress that cushions the body while maintaining even support. These are defining qualities of the WinkBed, a luxury hybrid with a deep comfort system and zoned pocketed coils. The mattress is available in four firmness levels, ensuring most people can find a comfortable design regardless of how much they weigh or which sleep position they use.

How It Performed

During our hands-on tests, the Softer WinkBed (4) earned its most favorable ratings from side and back sleepers weighing less than 130 pounds. This model contours closely to cushion the body and reduce soreness along the spine. Most of our testers felt comfortable on the Luxury Firm WinkBed (6) due to its balanced feel, with the highest ratings coming from side sleepers between 130 and 230 pounds and back and stomach sleepers up to 230 pounds. If you weigh more than 230 pounds, the Firmer Winkbed (7) and WinkBed Plus (8) will probably provide sufficient support.

Our temperature control tests for the WinkBed revealed very little heat buildup, with the firmest two models sleeping the coolest for our testers. We’ve attributed this to comfort layers that retain minimal heat, a coil system that generates steady airflow, and a moisture-wicking cover. The zoned coils also allowed the WinkBed to perform well during our edge support and ease of movement tests, and we believe the mattress should provide enough responsiveness for sex.

What It’s Made of

The Softer, Luxury Firm, and Firmer WinkBed models contain polyfoam comfort and transitional layers. The foams have open-cell compositions, so heat retention is minimal and you should sleep fairly cool. WinkBed Plus models swap the polyfoam transitional layer for 2.5 inches of zoned latex. This material feels very responsive, and you’ll notice extra reinforcement beneath your chest and hips. The WinkBed Plus is specifically designed for people who weigh more than 230 pounds.

The support core consists of pocketed coils in a zoned configuration. Thicker coils rest in the middle to push back against extra weight from your midsection, and the perimeter is reinforced to minimize sinkage when you lie or sit along the edges. A breathable Tencel cover encases the entire mattress.

WinkBeds offers free ground shipping throughout the contiguous U.S. The company’s sleep trial runs for 120 nights. If you aren’t satisfied with your initial firmness selection, you may exchange your mattress for a softer or firmer model after 30 nights. The replacement mattress is backed by an additional 60-night trial. No matter which WinkBed you ultimately choose, you’ll receive a lifetime warranty against structural defects.

Bear Original

Brand Logo
Mattress Type: Foam
Firmness: Firm (7)
Trial Length: 120 nights (30-night break-in period)
Warranty: Lifetime warranty
Sizes: Twin, Twin XL, Full, Queen, King, California King

Who it’s best for:

  • People who usually find memory foam mattresses too soft
  • Athletes and physically active individuals
  • Hot sleepers


  • Exceptionally firm all-foam design offers above-average support
  • Innovative Celliant cover engineered to sleep cool and help the body recover
  • Foam layers isolate motion very well

Sleep Foundation Exclusive Offer!

30% off sitewide + free accessories

Bottom Line:

Hot sleepers on our team often find foam models sink excessively and trap too much heat, but the Bear Original stayed cool. We recommend this model for anyone who likes the feel of foam but tends to overheat on all-foam mattresses.

The Bear Original has an appealing, innovative design with a firm (7) feel that’s more supportive than other all-foam models we’ve tested. The firmer feel also helps the mattress stay cooler than many other foam models. The approachable price-point, coupled with strong performance, makes the Bear Original a good long-term investment.

How It Performed

Children and teens are likely to find the mattress comfortable, as many prefer firmer mattresses compared to adults. The Bear Original offers other advantages based on its all-foam design. Sleep disturbances shouldn’t be a major issue, but most sizes smaller than a queen mattress tend to be insufficient if you share the bed with a partner. Our testers noted that the memory foam also provided even contouring along their spines, improving alignment and alleviating pressure in areas like the shoulders and hips.

Sleepers have had varying experiences with Celliant, but those who have attested to its capabilities include active people and those with physically demanding jobs. Based on our testing, the mattress is best suited to side sleepers who weigh more than 230 pounds, back sleepers who weigh at least 130 pounds, and stomach sleepers who weigh less than 130 pounds.

What It’s Made of

The mattress contains a comfort layer of memory foam that evenly contours to your body to relieve pressure. Next is a polyfoam transitional layer that evenly distributes weight to promote spinal alignment. The support core features high-density polyfoam that offers pushback to the hips and shoulders and limits excessive sinkage. One of the most notable features of the mattress is its cover made of Celliant fabric. This material is designed to convert your body heat into infrared energy, then transmit this energy back to you through your skin – a process that can help your body recover during sleep.

In addition to its low sticker price, the Bear Original also comes with a 120-night sleep trial and a lifetime warranty against structural defects. Ground shipping is free of charge throughout the contiguous U.S.

Best for Spinal Alignment

Saatva Youth

Brand Logo
Mattress Type: Innerspring
Firmness: Medium (5), Firm (7)
Trial Length: 365 Nights ($99 Return Fee)
Warranty: Lifetime, Limited
Sizes: Twin, Twin XL, Full

Who it’s best for:

  • Kids between the ages of 3 and 12
  • Children who frequently wet the bed
  • Shoppers who need help setting up their child's new mattress


  • Reversible, child-friendly design with each surface intended for a different age group

Sleep Foundation Exclusive Offer!

Bottom Line:

A thoughtful design and high-quality construction set the Saatva Youth apart from other mattresses created specifically for young kids. The reversible, fully waterproof design should serve your child well from their toddler years to preadolescence.

Spinal alignment is important for all sleepers, but especially for growing children. The Saatva Youth is a reversible innerspring with a distinct feel on each side. The softer surface has a medium feel (5) and provides cushioning to help children between ages 3 and 7 sleep comfortably through the night. The firm (7) opposite side feels denser and more supportive to promote proper development for kids ages 8 to 12.

How It Performed

As with most mattresses designed with children in mind, we relied on feedback from adults to rate the Saatva Youth. Temperature control was one area where the mattress excelled during our hands-on tests. We attributed this to internal layers that generate plenty of airflow and a breathable cover that retains very little heat. Another strong point was ease of movement. Unlike pocketed coils, which move independently and create minimal transfer, the Youth’s hourglass coils are highly responsive. As a result, the surface is quite bouncy to help your child move across the mattress without too much sink.

What It’s Made of

The surface intended for younger children begins with a foam layer divided into five firmness zones. This ensures adequate support around the midsection and gentler cradling for the rest of your child’s body. On the opposite side, a layer of high-density foam maintains a firm feel for older children. Both foam layers are convoluted to create room for air to circulate freely. The shared support core consists of hourglass coils made from recycled steel. A lumbar plate provides extra reinforcement to the lower back.

A breathable organic cotton cover encases the entire mattress. Both sides contain a waterproof membrane, which can protect the mattress from bedwetting episodes when your child is younger and other types of liquid damage as they age. A botanical-based Guardin treatment is designed to provide chemical-free antimicrobial protection. Please note the Saatva Youth has a weight capacity of 250 pounds.

Twin, twin XL, and full sizes are available. Saatva offers free White Glove delivery anywhere in the contiguous U.S. With this service, couriers set up the Youth in a room of your choice and remove your child’s old mattress upon request. The company’s generous sleep trial spans an entire year, and the mattress is also backed by a lifetime warranty against structural defects.

Mattress Type: Hybrid
Firmness: Medium Firm (6)
Trial Length: 100 nights (30-night requirement)
Warranty: 25 Year, Limited
Sizes: Twin, Twin XL, Full, Queen, King, California King

Who it’s best for:

  • Eco-conscious shoppers
  • Sleepers who weigh at least 130 pounds
  • Hot sleepers


  • Organic cotton and wool encourage airflow
  • Talalay latex gently cradles the body to alleviate pressure
  • Coil-reinforced perimeter bolsters the edges

Sleep Foundation Exclusive Offer!

20% off sitewide + 2 free Dream Pillows with mattress purchase

Bottom Line:

The Birch Mattress is an exceptionally cool mattress made with organic and natural materials. Breathable organic cotton and wool and Talalay latex offered cushioning for our testers without trapping excessive heat.

The Birch Mattress is a latex hybrid with a medium firm (6) feel that suits a wide variety of sleepers. Made from organic cotton and wool and natural Talalay latex, the Birch is an excellent option for shoppers seeking a mattress made with eco-friendly materials.

How It Performed

Thanks to the balanced medium firm (6) feel, our testers found the Birch comfortable across different sleeping positions and weight categories. Specifically, if you weigh at least 130 pounds, you should feel most comfortable on the responsive mattress. Our side and back sleepers under 130 pounds found the mattress too firm, but stomach sleepers in this weight category appreciated the extra support.

Like most other latex hybrids, the Birch performed well in our sex and temperature regulation tests. Responsiveness and extra edge support from the coil support core ensure couples can easily move across the surface and lay near the edges without slipping off. Meanwhile, breathable cotton, wool, latex, and coils made the mattress a standout in terms of cooling.

What It’s Made of

A blend of organic wool and rayon acts as a fire barrier, followed by a second layer of organic wool. Wool is naturally breathable and helps regulate temperature while giving the surface a plush feel. Next is Rainforest Alliance-certified Talalay latex that gently cradles your body and relieves pressure points without sinking too deeply. Latex is also naturally breathable, so it didn’t trap as much heat as adaptive foams during our tests.

Pocketed coils make up the support core. These coils move independently to offer targeted support where you need it most. Some coils are zoned along the perimeter for extra edge support. The coils rest on a base layer of wool and rayon for stability, and a breathable, organic cotton cover encases the mattress.

Birch ships free to all 50 states and offers a 100-night sleep trial for you to test the mattress. Purchases are backed by 25-year warranties, covering structural defects.

Sleep Foundation Exclusive Offer!

Get $160 off a Layla Memory Foam Mattress + 2 free memory foam pillows with code: SLEEPFOUNDATION

Bottom Line:

The Layla Mattress offers two firmnesses in one at an affordable price. The flippable design makes it a great option if you expect your firmness needs to change.

The Layla Mattress has a unique flippable design with a distinct feel on each side: medium soft (4) and firm (7). This versatility is excellent if you have growing children or varying firmness needs.

How It Performed

Our team found the soft side allowed side sleepers up to 230 pounds to sink in comfortably and find relief for pressure in their shoulders and hips. Back and stomach sleepers found the firm side more comfortable, keeping their bodies on an even plane. The softer side earned higher marks in motion isolation thanks to the thicker comfort system, and it cuts down on noise if you tend to change positions frequently at night. Hot sleepers on our team preferred the firmer side, which doesn’t contour the body as closely, thus trapping less heat.

What It’s Made of

The Layla’s comfort system differs depending on the side you choose. The softer side starts with a thicker layer of copper gel-infused memory foam that adapts to pressure points to help relieve aches and pains. The copper gel is meant to conduct heat away from the surface and keep you cool. Next is a polyfoam transitional layer that is thicker at the head and foot of the bed. This layer offers additional pressure relief to your joints while preventing excessive sinkage. The firmer side is made from thinner copper gel-infused memory foam and does not feature a transitional layer.

High-density polyfoam makes up the shared support core, offering pushback to reduce sagging in your midsection. A breathable polyester and viscose blend cover treated with a cooling agent encases the mattress, and this gave the surface a soft and cool feel during our tests.

Along with offering a competitive price-point, Layla offers free shipping if you live in the contiguous U.S. It also offers a 120-night sleep trial to test out a mattress before committing. If you decide to keep the mattress, it is backed by a lifetime warranty.

Sleep Foundation Exclusive Offer!

SF Readers get 15% off sitewide at Naturepedic with code SF15

Bottom Line

Featuring a waterproof side, the Naturepedic 2-in-1 Organic Kids Mattress is a great choice for young kids prone to wetting the bed. The lower profile also ensures many kids can get in and out of bed by themselves.

The Naturepedic 2-in-1 Organic Kids Mattress is a dual-sided innerspring made with organic materials. This reversible model’s waterproof side for easy accident cleanup, while the quilted organic cotton side offers extra cushioning as kids get older. We recommend this pick to eco-conscious parents seeking a mattress for a younger child.

How It Performed

Children do not test the products that come into our lab, but we make sure to test mattresses with kids’ needs in mind. We found the bed’s thin comfort system and robust support core maintained an even sleep surface that should feel most comfortable for children that sleep on their backs or stomachs. The 7-inch profile should be low enough for most kids to get in and out of bed easily. Thanks to the use of breathable cotton and coils, the mattress excelled in our temperature regulation tests. Our heat guns detected minimal heat buildup on the surface.

What It’s Made of

The dual-sided cover features a blend of waterproof organic cotton and PLA on one side and a quilted organic cotton and PLA blend on the other. The PLA fibers in the cover are polyester derived from sugarcane. Naturepedic recommends using the waterproof side through potty training and switching to the quilted side as your child gets older. Both have a thin comfort layer of cotton batting for light surface cushioning. The shared support core features bonnell coils that ensure full body support.

Naturepedic offers free ground shipping to customers in the contiguous U.S. and a 30-night sleep trial. The 2-in-1 Organic Kids Mattress is backed by a 10-year warranty against structural defects.

Why You Can Trust Us

We’ve evaluated hundreds of mattresses using hands-on methods to determine the best twin size models on the market. Our team includes side, back, stomach, and combination sleepers, as well as sleepers in different weight categories. This helps us evaluate mattresses from different points of view.

How We Evaluated These Mattresses

When testing mattresses, our team considers key performance areas by lying on the surface in different positions, using temperature sensors, and recording how closely the surface conforms to the body. Our top picks above represent the twin beds that earned the highest marks in our testing process.

More information about our product research methodology is detailed below:

  • Motion Isolation: Motion isolation is especially important if you are sensitive to your sleep partner’s movement at night. Mattresses ranking above average in this category help absorb movement and prevent it from transferring across the surface.
  • Temperature Control: Temperature control is most important to hot sleepers who need a mattress that dissipates excess body heat. Mattresses that rank highly in this category often have coil support cores to circulate air and enhanced cooling technology.
  • Pressure Relief: Pressure relief is particularly important if you sleep on your side or frequently wake up with aches and pains in your hips or shoulders. Thicker comfort layers should closely contour the body to reduce pressure buildup in these sensitive areas.
  • Off-Gassing: Newly unboxed mattresses can give off a bad smell during the off-gassing process. Mattresses featuring memory foam or polyfoam have the highest potential for off-gassing odors because they emit volatile organic compounds (VOCs).
  • Ease of Movement: A mattress with high marks in ease of movement should let you roll across the surface with little resistance or sinkage. Responsive mattresses made with coil support cores or latex comfort systems tend to rank well in this category.
  • Edge Support: A mattress with supportive edges allows you to put weight on the bed’s perimeter without feeling like you will slip off. Some mattresses feature reinforced edges for extra stability.
  • Sex: Although not entirely related to sleep, a mattress’ performance during sex is an important factor for many sleepers. Some things that contribute to how a mattress ranks in this category include bounce, temperature control, and noise suppression.
  • Body Weight: Considering your body weight is important to choose a mattress that is equally comfortable and supportive. Our recommendations based on weight category are subjective, so we encourage you to try different mattresses to find your ideal firmness level.

If you’re still not sure which mattress is right for you and your home, you can take a look at our mattress guides broken down by size.

How to Choose a Twin Mattress

Although it is the smallest mattress size, a twin can be useful in different situations. Twin models make great beds for children because they are generally inexpensive, so you won’t spend too much on a mattress that will most likely need to be replaced following a big growth spurt. Their affordability and space-saving dimensions also make twin mattresses a great option for college students sharing dorm rooms, or beds for a guest room in your house.

We’ll cover everything you need to know about twin size mattresses, including dimensions, price expectations, and other important factors for buyers.

What to Look for in a Mattress

Choosing the right mattress requires a fair amount of legwork on your part. You should research different brands and models to see how mattresses compare in terms of construction, feel, and price. Some mattress brands advertise their products using exaggerated and unrealistic descriptions. These include claims that their beds offer universal comfort regardless of your body type or normal position, or that a mattress will last forever.

Instead, we recommend using the following qualities and attributes to guide your new mattress search.

  • Price: The average mattress costs $500 to $1,000 in a twin size. However, price-points vary significantly by mattress type. Expect to pay less for a twin size all-foam or innerspring mattress, while hybrids, all-latex models, and airbeds will likely cost much more. Additionally, you should expect prices to be higher for certain brands.
  • Sleeping Position: People who sleep on their side often prefer softer mattresses that cushion the shoulders and hips. This helps to align the spine and alleviate pressure points. Back and stomach sleepers usually require more support to keep their bodies on an even, upright plane.
  • Mattress Type: Each mattress type provides a distinct feel. All-foam beds offer close contouring and respond slowly to your body. Latex beds also conform, but not as closely as all-foam models, so the surface has more bounciness. Hybrids and innersprings both feature coil systems that make them feel responsive, but hybrids typically have thicker comfort layers that offer more contouring. Airbeds allow you to customize the firmness by adding or releasing air from their support core chambers.
  • Contouring: Whether a bed conforms very closely or barely at all, the contouring should be even across the surface. This ensures enhanced support for your lower back, hips, and other areas where people carry a disproportionate amount of weight, and gentler cradling for your head, neck, shoulders, and legs. Beds that do not contour evenly may cause added pressure points and other aches and pains.
  • Quality Materials: Certain mattress materials are associated with better durability and stronger performance in specific categories. These include high-density memory foam for exceptional contouring and pressure relief, breathable and eco-friendly organic latex, and thick steel coils to support the bed and reinforce the edges. You may pay more for mattresses with these components, but you’ll get more mileage and comfort out of your bed.
  • Firmness Level: Mattress firmness is evaluated using a 1-10 scale, with 1 being the softest and 10 the firmest – though most mattresses made today fall between 3 and 8. A softer mattress (1-3) will conform more closely, so you should expect deeper contouring and more sinkage. A firmer mattress (7-10) won’t conform as much, but these models feel more supportive. Many sleepers prefer a mid-level firmness (4-6) with a balance of contouring and support.
  • Pressure Relief: The best mattress for pressure relief will cushion your body and support the spine without sinking too deeply beneath heavier areas of your body. People who weigh less than 130 pounds often find that softer mattresses alleviate the most pressure thanks to their close conforming. Those who weigh more than 230 pounds will probably prefer a firmer bed that won’t sink too deeply in certain areas.
  • Edge Support: Edge support refers to how well the support core components reinforce the perimeter against deep sinkage. Coils typically offer the strongest edge support. You won’t sink very much when getting on and off most hybrids and innersprings. Foam and latex support cores cannot withstand compression as well, so you’ll probably sink a bit more on these models.
  • Temperature Regulation: Mattresses usually sleep cooler if they are constructed with breathable components such as ventilated foam or latex, coil systems that promote airflow, and covers made from natural fabrics and fibers. People who weigh 130 pounds or more may also find that they sink less on firmer mattresses, resulting in better surface airflow and more comfortable temperatures.
  • Noise: The coils found in innersprings and hybrids may produce squeaks and creaks that you find disruptive. This issue tends to worsen over time as the springs wear out. Foam and latex support cores do not produce any noise, so mattresses with these base layer components are usually silent.

Who Is Best Suited to a Twin Mattress?

The twin size mattress – also known as a single – usually measures about 39 inches wide and 75 inches long. This size is better suited to certain types of sleepers, and less so for others. Couples and co-sleepers often find twin beds too narrow, whereas most single sleepers enjoy ample space to move around during the night.

Based on its dimensions, we recommend a twin size mattress for the following sleeper groups:

  • Toddlers and Kids: Twin size mattresses offer more than enough space for most growing toddlers and young children. Since they’ll likely undergo growth spurts in the years ahead, buying a twin for their first big kid bed can be very cost-effective. Twins also take up less space than other mattress sizes, which can be handy if the child’s bedroom is on the smaller side, and many bunk beds for room-sharing siblings are compatible with twin size mattresses.
  • Teenagers: As with toddlers and kids, teenagers typically experience major growth spurts. While the twin will be too short for teens who stand taller than 6 feet 2 inches, these mattresses should offer enough legroom for shorter teens without their feet dangling over the foot of the bed.
  • College Students: Many college students who share dorm rooms choose twin beds for their narrower and shorter dimensions, as larger sizes take up more floor space. Twins also tend to be a cheap mattress option for students on a budget. Additionally, many bunk- and loft-style beds available to dorm dwellers can accommodate a twin-size mattress.
  • Single Adults: If you normally sleep alone and do not share your bed with another person very often, then a twin size mattress should provide ample space – provided your height doesn’t exceed 6 feet 2 inches, in which case you may need a twin XL. Twins are especially useful if your bedroom or apartment is somewhat small and you’d like to conserve space.
  • Those with Guest Rooms: Twin beds are ideal if you frequently host single houseguests. They won’t take up as much space as a foldout sofa, and twin models tend to be more comfortable than futons or sofa beds.

Twin vs. Twin XL

The twin and twin XL are the smallest standard mattress sizes. Most twins measure approximately 39 inches wide and 75 inches long. The twin XL shares the same width of 39 inches, but most of these models measure 80 inches long.

Neither size is suited to couples or co-sleepers, but a twin XL will be more comfortable if you stand between 6 feet 3 inches and 6 feet 7 inches tall. If you’re in this category, you may be  a bit too tall for a standard twin and your feet will probably dangle over the foot of the bed. Meanwhile, a twin XL provides extra space for your legs and feet.

Pros and Cons of a Twin Mattress

Like other mattress sizes, twins carry their own pros and cons for sleepers and shoppers. Some notable benefits and drawbacks of twin size beds are listed below.

  • Generally the lowest price for any given model
  • Takes up less floor space than other mattress sizes
  • Cost-effective option for growing children and teenagers, as well as college students
  • Compatible with most bunk bed models
  • Long enough for people who stand 6 feet 2 inches or shorter
  • Too narrow and cramped for most couples and co-sleepers
  • Limited availability for certain mattress types, such as airbeds and luxury high-profile models
  • Too short for people who stand 6 feet 3 inches or taller

What Type of Mattress Is Best for a Twin?

Next, let’s take a closer look at the five main mattress types. Mattresses sold today fall into five general categories based on how the comfort layers and support core are constructed: hybrid, innerspring, latex, airbed, and all-foam. Mattress types generally earn the same ratings in performance categories like durability, pressure relief, and temperature neutrality. However, you’ll notice a lot of variation with these categories in terms of feel, price, and other factors.


Definition: Hybrids are technically innersprings, but they are constructed with comfort layers of memory foam, latex, and other materials that conform more closely. As a result, we find they tend to alleviate more pressure than traditional innersprings. Hybrids almost always have pocketed coil support cores, as well.
All-Encompassing Design: Hybrids are designed to perform well in several different areas. Their contouring comfort layers offer extra support for the spine and more pressure relief for sleepers – our side sleepers, in particular. However, their coil systems also provide enough reinforcement for most of our back and stomach sleepers to lie comfortably without sagging too much. Hybrids sleep cooler than most all-foam models, while earning higher marks in motion isolation than the average innerspring.


Definition: Innersprings are the oldest mattress type still sold today, as well as the most popular among U.S. consumers. Most feature thin comfort layers of polyfoam (and possibly memory foam) over a support core of open steel coils. As a result, innersprings often feel quite responsive on the surface regardless of the firmness level.
Excellent Temperature Regulation: Innersprings tend to sleep cool during our temperature control tests for a few reasons. Since their comfort layers are usually somewhat thin, they won’t absorb and trap much of your body heat. Their coil systems also promote steady airflow to help the mattress maintain a cool interior temperature, and their responsive surfaces prevent most sleepers from sinking too deeply.


Definition: Latex is a material derived from the sap of rubber trees. It can be processed with chemical fillers to create a soft, foamy material that conforms to your body while also maintaining some natural responsiveness. Latex is also very durable, so you can expect a healthy lifespan from your twin size latex mattress.
Contouring Without the Sink: Latex beds are suitable if you prefer some noticeable body-conforming, but don’t want to sink too deeply into your mattress. The latex layers also offer great longevity and won’t develop deep body impressions as quickly as memory foam or polyfoam layers.


Definition: An airbed is constructed with two or more air chambers in its support core. You can add or release air from individual chambers, which in turn changes the firmness in different areas of the sleep surface. Some airbeds also include comfort layers of polyfoam, memory foam, and other contouring materials.
Highly Customizable: Due to their adjustable feels, airbeds offer unparalleled customization compared to other mattress types. However, many airbeds are designed for dual-firmness, or a different feel on each side, to accommodate couples with different comfort preferences. As a result, you’ll have a harder time finding high-quality airbeds in the twin size.


Definition: An all-foam mattress is constructed with comfort layers of polyfoam and/or memory foam, along with a support core of high-density polyfoam. Many models also include transitional polyfoam or memory foam layers to prevent you from sinking too deeply. These mattresses respond slowly to your body and often conform quite closely, so you should expect less springiness and more sink.
Exceptional Pressure Relief: All-foam beds offer closer conforming than other mattress types. For most sleepers, this means better pressure relief around the shoulders, lower back, hips, and other sensitive areas. If you experience frequent pressure points, then you should consider an all-foam bed – but take your body type and sleeping position into account before choosing a model to ensure the bed will be soft/firm enough.

Last Things to Consider with a Twin Mattress


Before you head off to find the right twin size mattress, take a few more minutes to peek at our final considerations for twin mattress buyers.

Who Will Use the Mattress?

This is an important consideration because the best twin mattress for adults may be a bit different than the best model for children and teenagers. If you plan to use the twin size mattress yourself, be sure to compare different models based on how the beds feel. The firmness level of the mattress you choose should align with your body type and sleep position, as well as your general preferences for how soft or firm a surface should feel.

If you’re buying the mattress for a child or teenager, first get their input on what kind of mattress they’d prefer. You may want to consider visiting a brick-and-mortar mattress store, where your child can try out different beds and see which firmness and responsiveness levels feel most comfortable. The best twin mattress for a toddler should offer a bit more support to ensure they don’t sink too deeply into the bed.

If you are a college student planning to use a bunk- or loft-style bed, or you have children with the same type of bed, keep in mind the bed’s thickness should should correspond to safety rails on the top bunk. Read below for more details on bunk beds.

Is the Mattress for a Bunk Bed?

Many bunk beds are specifically designed for twin size mattresses. These include standard double and triple bunks, as well as twin-over-loft beds with an open area beneath the top bunk.

One thing to keep in mind when selecting a twin mattress for a bunk bed is thickness. According to the U.S. Consumer Product Safety Commission, the mattress used on a top bunk should be at least 5 inches shorter than the guard rails on either lengthwise side. For this reason, a low-profile mattress of about 6 or 7 inches thick will be optimal for most bunk beds.

Mattress Warranty and Other Policies

Before choosing a mattress, take a glance at the brand’s shipping, return, and warranty policies. You may save a lot of money down the road by choosing a model backed by favorable policies for owners.

If you order your mattress online and reside in the contiguous U.S., chances are the retailer will mail your “mattress in a box” free of charge via standard ground shipping. Customers in Alaska, Hawaii, and other places outside the contiguous U.S. usually need to pay extra delivery fees.

Your mattress will probably come with a sleep trial of at least 90 nights. Most online mattress brands offer free shipping and full refunds for returns within the trial period, but some charge return fees. Be sure to check the fine print on how much of a refund you’ll receive.

All mattresses come with a warranty of some kind, and most last 10 years or longer. If the warranty is non-prorated, then you won’t pay anything to have a defective mattress repaired or replaced apart from some nominal shipping fees. If the warranty is partially prorated, then you’ll pay a certain percentage of the bed’s original price to have the mattress replaced. This percentage usually increases for each year you own the mattress.

Common defects covered under a mattress warranty include body impressions in the surface that measure 0.5 to 1.5 inches deep (this varies by model), manufacturing flaws that cause materials to deteriorate prematurely, and defects associated with the cover. Other issues, such as normal wear and tear or physical damage you cause to the mattress, will not be covered.

Twin Mattress FAQ

What are the dimensions of a twin mattress?

A standard twin mattress measures 38 to 39 inches wide and 75 inches long. Exact dimensions vary from model to model, so there may be a 1-inch margin of error for the width or length.

Twins are considered the smallest of the six standard mattress sizes. They share the same width as a twin XL and the same length as a full/double.

How much does a twin mattress cost?

The twin is usually the most affordable standard size for most mattresses, though some models cost the same for twin and twin XL sizes. The price-point of a twin size mattress depends on several factors but material composition usually plays the biggest role.

All-foam mattresses and innersprings have the lowest average prices among major mattress types. For a twin size foam or innerspring model, you may pay as little as $300 to $500. Hybrids have a mid-range price, so you can expect to pay about $700 to $1,100 for a twin. All-latex models cost a bit more – $1,100 to $1,500 for the average twin model. Airbeds are normally the most expensive mattress type on average, but these models are rarely available in a twin size.

Other factors that affect price-point include the brand you choose, and whether you purchase the mattress online or at a brick-and-mortar mattress store.

How much does a twin mattress weigh?

Twin is considered the smallest standard size, which also makes it the lightest size, but the weight of a given twin size mattress depends on its thickness and material composition.

All-foam mattresses typically weigh less than other mattress types, and a twin size model will probably weigh 35 to 50 pounds. Hybrids and innersprings are a bit heavier due to their steel coils. These models weigh 60 to 75 pounds in a twin size on average. All-latex mattresses are the heaviest mattress type. Even in a twin, these models can weigh more than 90 pounds.

Do two twin mattresses make a king?

A standard twin measures 38 inches wide by 75 inches long, while a standard king measures 76 inches wide by 80 inches long. Two twins pushed together will provide the same width as a king, but the length will fall 5 inches short.

A twin XL – the next largest standard size after a twin – measures 38 inches wide by 80 inches long. Placing two twin XL models together will create the same dimensions as a king. The “split king” size for couples who use adjustable beds is essentially two twin XL models that are placed side by side.
