Who should get a twin size mattress?
Twin size beds are the gold standard for kids, teenagers, college students, small guest rooms, or single adults with limited space.
A twin size mattress fits in virtually any living space, including dorm rooms, guest bedrooms, or kids’ rooms.
Surprise visitor? You can still offer them a great night’s rest with a comfortable, supportive twin.
You can fit a twin size bed in a bunk, trundle, or a shared bedroom. They’re the perfect size for your growing child.
How much should I expect to spend on a high-quality twin size mattress?
Mattress shopping can be a pain, but if you go in with reasonable budget expectations, you’re more likely to have a smooth buying experience. A “luxury” twin size mattress may cost $2,000 or more, but most of the time, overpriced beds aren’t as high-quality as they might seem. On the other hand, cheap beds that class="promo-price js-promo__price js-promo__with-promo"come with promotions (BOGO or “buy one get one % off") are not likely to last very long, either.
Sometimes the extra bells and whistles that drive up the cost of a mattress aren’t on your priority list, and that’s fine. You can still find a basic, high-quality mattress for a fair price. If, however, you are looking for some extra features, note that they can increase the cost. Some of the more common added features are:
- Cooling technologies, such as gel memory foam, copper-infused foam, advanced open-cell foams, plant-based foam, or precision cut-channels and zoned support.
- Added edge support (either in the form of quilted pillow topstitching or poly-foam reinforcing the edges)
- A longer than average warranty (the mattress industry standard is a 10-year warranty)
- White glove delivery if included with purchase
- Brand name and reputation
- Amount and/or quality of materials (for example, softer beds use more layers of foam so they tend to cost more; hybrids cost more because they use a combination of coils and foam; natural latex mattresses cost more because of their sustainability and durability)
- All-natural materials, such as organic cotton, natural latex, or CertiPUR-US® certified foam, Greenguard Gold Certified foam, and so on
Common mattress features increasing mattress cost
- Cooling technologies, such as gel foam, copper-infused foam, or plant-based foam
- Proprietary foams or technologies (materials made exclusively by and for the brand)
- Edge support (in the form of poly foam or other materials reinforcing the edges)
- A quilted Euro top layer (Euro pillow tops are more expensive than plush pillow top mattresses because they contain higher quality materials)
- A longer than average warranty (average is 10 years)
- Thicker comfort foams (in general, softer beds use more layers, and are therefore more expensive)
- Eco-friendly materials, such as organic cotton, latex, or plant-based foams

Does a high-quality bed in a box really exist?
Thanks to the new bed in a box trend, memory foam has become more and more popular because it’s easy to compress and roll into a small box for delivery. While eliminating the middleman of a retail store and overhead costs, some still wonder if beds in a box have comparable quality to the mattresses you can find in a store.
Let’s ease your mind by answering the most frequently asked questions surrounding beds in a box:
Will shipping the mattress in a box change its feel?
No matter if you bought a firm mattress or an ultra-plush one, the way it’s shipped to you shouldn’t change the feel. Mattress companies use special machines to carefully compress and roll the mattress without compromising the layers or firmness.
How long do I have to wait before sleeping on my unboxed mattress?
Some brands recommend you do not sleep on your mattress for at least 24-48 hours after opening it to ensure it’s completely expanded. However, if you want to try it out immediately, it shouldn’t damage the mattress at all.
What do I do if there’s a chemical smell?
Many memory foam beds come with a chemical smell, known as “off-gassing.” It’s harmless, but it can disrupt sleep if it doesn’t go away within a few days. If your bed still isn’t airing out a few days after you’ve opened it, that could be a sign of low-quality foams. Instead, look for mattresses made with plant-based foams that limit the amount of petrochemicals used in manufacturing.

What sets Amerisleep’s mattresses apart
traditional memory foam beds?
Amerisleep makes their mattresses using high-quality materials made to last. Their 20-year warranty is one of the best in the industry and it’s built on a foundation of unique, proprietary foams engineered to give you the best sleep imaginable, no matter how you sleep.
Their signature Bio-Pur® foam— the top comfort layer in every Amerisleep mattress— contains castor oil, a plant-based foam that helps to reduce the familiar off-gassing smell associated with memory foam. The advanced open-cell foam allows more air to pass through, keeping you cool. Instead of infusing their foams with other cooling agents that may become ineffective, we simply make the foam itself more breathable and responsive.
The Affinity layer with HIVE® is present in every mattress except the AS1. It acts as a transition layer between the soft Bio-Pur® and the firm Bio-Core® support foam base layer. The hexagon-shaped cutouts in this layer are closer together in areas that need firmer support, such as the head, back and feet; they are spaced farther apart in the shoulders and hips where sleepers typically need more softness.
The 7-inch Bio-Core® layer at the bottom of each Amerisleep mattress prevents the softer top layers from sagging, so no matter how long you use it for, your Amerisleep mattress should not sag.
The Amerisleep AS5 has one layer the other beds in our lineup do not have— the Active Flex layer. The Active Flex sits between the Affinity layer and the Bio-Pur®. Because the AS5 is so soft, we needed another layer to ensure whoever slept on the bed didn’t feel stuck or like they were sinking. The Active Flex bounces back quickly, never sacrificing support for softness.
The soft and ultra-breathable cover on every Amerisleep mattress helps prevent overheating, so you can sleep your best each night.

Firm and worth the price.
The mattress is firm enough to keep my lower back from hurting but soft enough for a good night’s rest.
Second to none.
I was anxious to buy this mattress at first. I'm very picky because of my back surgery and need a mattress that supports me well as a stomach sleeper. If you know what I'm saying, stomach sleeper for someone with spine surgery is a big no. But this mattress made it possible. After 9 years, I've got a restful sleep. Thank you Amerisleep.
I never write reviews but had to give credit where credit was due. I love the heck out of this mattress. I've always complained of back pain and a good mattress is imperative to me. This mattress was so dang easy to open, got it up my stairs without an issue, because it was still in the box. Opened it in the morning, slept on it that night. Unbelievably comfortable. Remarkable customer service. Prompt delivery. Totally recommend.

Reduced our back pain dramatically
I'm a stomach and back sleeper and my husband is a side sleeper. I love that this bed works for both of us and has dramatically reduced back pain for both of us. It used to take me 30 mins to get out of bed in the morning because my back hurt so much and I'm 31 years old !!!! Good riddance old mattress !!! I now pop up out of bed within 5 mins of waking and ready to start my day. I couldn't be more pleased with this company and our new bed.
The answer to my prayers
When I read the other reviews, I was skeptical. I have a bad back, and my old mattress was just making matters worse. It was a traditional mattress. I decided to go with Amerisleep AS2. The mattress is very firm but soft to the touch at the same time. I have had the best sleep in years after purchasing this mattress. And a lot of my back pains are gone. I am very happy with this mattress and I plan to replace my daughter’s mattress with another Amerisleep mattress.
Insane back relief
I have suffered from disc issues in my back for the past 15 years. I have had daily pain for the past five years. My back and hip pain have been almost entirely eliminated within one month of sleeping on this mattress. It has improved my daily quality of life and is by far the most comfortable mattress I have ever slept on.

I would definitely rebuy this exact mattress in the future!
I love that it comes more firm in the beginning and softens up as time passes by. I heard about it from a friend and tried their bed and ordered one for ourselves and been very happy with it.
This mattress is incredible! My wife and I have done countless hours of research for the best mattresses on the market. Amerisleep is, by far, the best product for quality sleep, comfort, and overall satisfaction!
I would buy this product again
I have a bad back. My husband and I bought a new bed about a year ago. Unfortunately, I'm at the point the bed is to soft for me to sleep on. I have searched several bedding stores and they all said the same thing. If I didn't like the bed I could get a store credit. My fear was what if I can't find a bed I can sleep on in their store. That's why I like Amerisleep. They guarantee satisfaction or your money back. Luckily I first bed I purchased with Amerisleep has been awesome. I would recommend Amerisleep to everyone.
Soft and supportive.
This bed is amazing, it's more on the softer side but I like it like that. It's got great support too. I've always woken up with back pain on my previous mattress but not with this one.
Great Mattress. Sleeps cool and has the level of firmness as described. I tend to prefer a firmer bed (back issues) and my wife prefers very soft beds. The AS4 is perfect for both of us. Soft while giving good support. I am surprised some folks have rated it as "way too firm." My wife loves a super soft bed and absolutely loves it. Would 100% buy again.
This product is AMAZING!!!!!
This mattress has truly changed my life. Years on end I've been waking up multiple times during the night due to either heat or the stiffness/cratering of my generic mattress. My Amerisleep mattress has me sleeping through the entire night both cool and comfortably, I truly feel like I am sleeping on a cloud. Thank you Amerisleep for such an amazing product! I highly recommend this product to anyone in need of a new mattress or that is currently experiencing sleep issues.
A great mattress for bony side-sleepers!
Because of our narrow staircase to a converted loft, we had to choose a mattress in a box or we could not do a king-sized mattress. While heavy, the Amerisleep mattress was manageable up the stairs and very easy to open. I love that it did not off-gas at all. Zero. We've slept on it for more than a month now and it's starting to soften considerably. Perfect for both of us as we are side sleepers who need a softer mattress for our pressure points. I don't wake up sore anymore.
New to Memory Foam
This was my first memory foam mattress and I had read mixed reviews so I was nervous about having an adjustment period and not being able to rest during that time. For me, there was no adjustment with this mattress. I slept great the first night and every night since then. I no longer wake up with pain in my hips and legs and it's amazing.
We love our new Amerisleep mattresses!
My husband and I purchased this as a new bed for ourselves. We both suffer from back problems and I found myself waking up many mornings to aches and pains in my hips and shoulders. Mattresses are not an easy purchase, especially with so many options out there, but Amerisleep made this process a breeze! We purchased the AS5 and we love it! It is soft and comfy, yet supportive. We are sleeping so much better and I'm not waking up with hip and shoulder pain! We've even noticed a decrease in snoring. :)
Frequently asked questions
The size of twin size beds makes them one of the most versatile mattresses. They can fit in a bunk bed, trundle bed, guest room, small apartment, dorm room, and more. Some of the more popular foundations used with a twin size bed are:
Box spring:You can use a box spring with an innerspring mattress and some hybrids, although we do not recommend using one with a foam bed. The wooden and/or metal in a box spring can cause the foam to droop and sag prematurely.
Slatted base:Slats connected with fabric or attached to the bed frame are another popular option, and they do not require a box spring. Simply place your mattress directly on top of the slats (make sure they are aligned and stabilized first). Amerisleep specifically recommends using our mattresses on slats no more than 3 inches apart to avoid any sagging.
Platform BedA platform bed is a sleek, minimal option that works well with most mattress types. Keep in mind that if the base has no slats, airflow and breathability through the mattress might be an issue.
Adjustable bed:An adjustable bed may seem it’s only meant for those with chronic pain or sleep-disordered breathing issues such as snoring or sleep apnea. While adjustable beds can help with these problems, they’re also a great choice for anyone who just wants to sleep better. With an adjustable bed, you can elevate your head or legs for improved breathing, circulation, and posture. An adjustable base puts less pressure and stress on your back. Currently, Amerisleep offers an adjustable base for Twin XL, full, queen, and split king mattresses.
Metal frame:You can use your twin size bed on a metal frame as long as it has built-in support in the form of slats or a platform. If you want a headboard, most can be attached to a basic metal frame, but always check the manufacturer instructions for best compatibility.
Maybe you’re not sure which type of base will mesh with your home decor and you’d rather put your mattress directly on the floor— we recommend against this because it impedes airflow through the bottom of the mattress. To ensure you get a good night’s sleep, choose a strong, supportive bed foundation to go with your new twin size mattress.

The best twin mattress for you largely depends on your sleeping position, as well as your budget, comfort preferences, and how much you plan to maintain it.
Best Mattress for Side Sleepers:Side sleepers are already in a relatively healthy position for minimal back pain and snoring, but they are prone to numbness or tingling in their limbs, especially if their mattress is too firm. That’s why most brands, including Amerisleep, recommend side sleepers choose a medium to soft mattress. Your body type can affect the feel of a mattress as well, so always choose one with plenty of pressure relief and sturdy support.
Best Mattress for Back Sleepers:Back sleepers aren’t at risk for misaligning their spines, but they can suffer from snoring or sleep apnea because of the way gravity presses down on the soft tissues of the throat. To maintain even support for their whole body, including their heads and necks, back sleepers need a firm or medium-firm mattress.
Best Mattress for Stomach Sleepers:Overall, we do not recommend stomach sleeping because of the strain it puts on the back and neck. However, if you’re set on sleeping this way, choose a firm or medium-firm mattress to keep your spine in a neutral position. If you’re ready to switch to the healthier side-sleeping position, you can use a body pillow to keep comfortable while you adjust.
While memory foam is certainly one of the more popular options, there are other choices for those who aren’t quite ready to take the memory foam plunge.
Memory Foam Mattresses
How is memory foam made? It all starts with polyurethane foam, and then other materials are added to give it a soft, viscoelastic feel (hence the name “viscoelastic foam”). Memory foam has an open-cell structure meant to give it a responsive, springy feel.
No memory foam mattress is made with 100% memory foam— that would be a very unsupportive bed indeed. Most often, the memory foam appears in the top comfort foam layer(s) and is then supported by a firmer foam, usually poly-foam. Additional layers are added depending on how soft the company wants the mattress to be.
Memory foam is largely popular because To offset the fact that high-density foam traps heat, many brands infuse their foams with cooling gels or other materials, boosting breathability and responsiveness.
Innerspring beds use steel coils for their base and thin layers of poly-foam or memory foam in the comfort layers, also known as the pillow top or Euro-top. Innerspring mattresses are not known for their pressure relief or motion isolation (like memory foam), and they start to sag after only a few years.
Hybrid mattresses are a combination of memory foam and innerspring beds. They contain more foam in the top layers than a typical innerspring, and the steel coils are often wrapped in fabric to reduce motion transfer.
Hybrids are sought after because they seem to have all the pros of innersprings and memory foam mattresses without their cons; however, the average lifespan of a hybrid mattress is only 1-2 years longer than an innerspring, so they may not be worth the extra cost.
Like memory foam beds, latex mattresses are pressure-relieving, silent, and hypoallergenic. However, they have a bouncier, firmer feel to some and they typically cost more. Latex beds are not as readily available as the other mattress types, but if you can find one, you’ll probably like them for their durability— some latex beds can last for up to 15 years.
Before you choose your perfect twin size bed, consider the pros and cons of each mattress type.
|Benefits||Amerisleep Mattress||Innerspring Mattress||Traditional Memory Foam Mattress||Hybrid Mattress||Latex Mattress|
|Responsiveness||Bounces back in seconds||Bounces back very quickly||Responsive but prone to sagging||Slow to respond, results in "stuck" feeling||Very responsive|
|Pressure Relief||Exceptional pressure relief||Little to no pressure relief||Good pressure relief||Some pressure relief||Good pressure relief|
|Cooling||More breathable than traditional memory foam||Cooling thanks to the coils in the base||Traps heat||Cooling thanks to the coils in the base||Cooling as long as top foams are aerated|
|Foam quality||Partially plant-based Bio-Pur® material||Usually made with poly-foam pillow tops||Foam usually made with petrochemicals||Depends on the type of latex used; synthetic latex breaks down faster than all-natural||Only high-quality if 100% natural|
Queen and king size mattresses come in a few different variations, but twin size mattresses are only available in two types: twin and twin XL. A twin XL is a good option for a growing child, especially if you’re not planning on transitioning them out of that mattress until they leave for college. However, if you’re just using the twin for a guest room, a bunk bed, or a shared bedroom, a twin is a perfectly suitable choice.
|76 inches wide, 80 inches long||72 inches wide, 84 inches long|
Maybe you’ve been sleeping on the same mattress your whole life and you’re still not sure which “firmness” will be most comfortable for you. We recommend referring to your sleeping position (discussed above) as well as your body weight. If you’re buying a twin, you’re probably not sharing your mattress with a partner, so you don’t need to worry about their weight or sleeping style affecting the firmness or feel.
Many mattress brands differentiate firmness using the firmness scale, which goes from 1-10, with 1 being plush and 10 being extra firm. In general, most mattresses don’t rate on the extreme ends of the scale— they fall between 3-8, with a little variance depending on the brand.
Firm (firmness scale: 8-9, AS1)
- Best for back sleepers and stomach sleepers who like a firm mattress with very little give
Medium-Firm (firmness scale: 6-8, AS2)
- Best for those with back pain
- Best for back and stomach sleepers who need extra pressure relief
- Best for heavyweight sleepers who prefer a firm feel
Medium (firmness scale: 5-7, AS3)
- Best for side sleepers and combo sleepers who prefer an even balance of softness and firm support
- Best for average weight sleepers
Medium-Soft (firmness scale: 4-5, AS4)
- Best for side and combo sleepers who need extra pressure-relief and softness
Soft (firmness scale 2-3, AS5)
- Best for heavyweight sleepers who prefer a soft bed
- Best for petite sleepers who prefer a soft bed
- Best for the dedicated side sleeper who needs extra pressure relief
A high-quality mattress will last at least as long as its warranty, never lose support, and leave you waking up refreshed and well-rested every night. To maintain the quality of your new twin bed, always use a mattress protector or encasement; these will deter bed bugs, dust mites, and spills.
|Mattress Type||Average Lifespan|
|Amerisleep Mattresses||15-20 years*|
|Traditional Memory Foam||7-10 years|
You can tell a lot about how long a mattress will last by checking out the warranty. The mattress industry’s standard length warranty is 10 years, since most experts recommend switching out your mattress after about that long. However, many mattress types begin to show signs of sagging and deterioration before that point because the foams are poorly made, the base layer is not dense or thick enough, or the mattress is poorly protected from allergens, bed bugs, dust mites, or spills and stains.
If you’re planning on using your twin mattress in a guest room, you can expect it to last longer than average.
The typical mattress warranty lasts about 10 years and it usually covers sagging below a certain depth as well as manufacturing defects. If the twin mattress you’re considering doesn’t come with a warranty, we suggest going elsewhere. Twin size beds need to withstand a lot of wear and tear, especially if they’re for a kid’s room or a daybed used for everyday lounging.
Most new mattresses require an adjustment period lasting around 20-30 days, and the sleep trial most often covers that and more. However, if you’ve passed the 100-night trial period and your mattress still feels too soft or firm, you can adjust it with a mattress topper. A couple of the most popular toppers include:
Gel memory foam mattress topper:infused with gel or gel beads, these toppers are meant to dissipate body heat while adding an extra layer of softness to your mattress.
Convoluted foam mattress topper:Also known as “egg-crate foam” because of its shape, this topper type is meant to add more support and contouring.
Amerisleep makes two different toppers: one for added softness and one for added support, depending on your needs. Both toppers are made with HIVE® technology, the ergonomic sleep system that simultaneously supports and eases pressure points.
Yes, a twin size and a single bed are the same size. The word “twin” in “twin size” simply refers to two single beds side by side, like you would find in a shared bedroom or dorm room.
Alternatives to Twin Mattresses
Twin XL mattresses are a fit for growing children, college students, and even single adults—they provide 5 extra inches of legroom to accommodate taller sleepers.
Sleepers who prefer
Full mattresses are best for combination sleepers, those who like to sprawl, and those who co-sleep with a child or pet.
Queen mattresses are a popular choice amongst couples and single sleepers who prefer a large bed to get comfy.
