Best Twin Bed: Overview

When you’re looking for a new twin size mattress there are a few things that you’ll be paying attention to that you won’t, perhaps, with a king mattressCalifornia king mattress, and so on. The first thing is that you’re almost certainly looking for a bed for a kid, so price is very important since they will grow out of this bed quickly. Additionally, you want a bed that’s able to accomodate a variety of sleeping positions since kids tend to toss and turn at night. In this post, we have considered the above factors and much more. (And don’t worry, adults sleeping on a twin mattress. We’ve got you covered, too.)

Shipping, Returns, etc.

For the most part, when you buy a mattress online it will come with free shipping—that’s regardless of whether you buy an Amazon bed or directly from a brand. From there, you typically get a trial period just to make sure the bed works for you. Most of the time, the trial period is about three months. In the event that you’re not completely sold on the mattress, nearly all bed-in-a-box mattress brands offer 100% free returns, which is nice since it limits your downside.

Cocoon Classic


  • Anyone that likes memory foam
  • Those who want a bed from Sealy (a mega mattress brand)
  • Shoppers who want to choose between two different firmness levels


  • Strict side sleepers that want a very soft mattress
  • Extra hot sleepers

Cocoon Classic is the bed-in-a-box offering from Sealy, which is one of the largest bedding companies in the world. This is a memory foam mattress that’s available in two different firmness levels: Soft and Firm. Both have a true, dense memory foam feel, but the Soft version is, well, a bit softer than the Firm version.

Cocoon Classic has a memory foam feel.

We’d put both firmness levels around a medium-firm on the soft-to-firm scale. They aren’t proper firm mattresses nor are they soft mattresses. We see this as a good thing since it means they’ll be able to accommodate a range of sleepers.

Having said that, we would say that Cocoon Classic is better for back and stomach sleepers than it is for side sleepers. It just doesn’t offer the deep pressure relief, although the support is definitely there.

Bear MLS Mattress


  • Kiddos that love sports
  • Amazon shoppers (it's only sold via Amazon)
  • All sleep styles


  • Heavier kids that need a thicker mattress

Feb 2019 UPDATE: This particular mattress is no longer available because Bear no longer has a contract with Major League Soccer. You can see the new line of beds on Bear’s website.

The Bear MLS mattress is interesting and fun, and we think it makes for a wonderful kid’s bed. It’s only 8″ thick and doesn’t have the typical 100-night trial period—since it’s only sold via Amazon—but there’s a lot to like. It’s comfortable, accommodating, and how can you not love the little MLS logos on the cover?

This is just a fun mattress.

One other thing that’s great with the Bear MLS mattress is that it’s highly affordable—a twin size mattress sells for under $300 on Amazon (with free shipping). This isn’t going to be the bed that your kiddo keeps forever, but for the price, it’s a really nice bed.

It has more of a neutral feel and sits between a medium and medium-firm on the soft/firm scale. We think the majority of people will find it comfortable. If fact, the nephew of one of our team members sleeps on the Bear MLS mattress. Naturally, he is now a huge soccer fan and absolutely loves his bed.

Allswell Hybrid


  • Those whose #1 concern is value
  • Anyone that wants a firmer, supportive bed


  • Those who want a super soft bed

We couldn’t help but notice that adults are also searching for twin size mattresses. For what reason, we don’t know. It could be that they want a bed for camping, their truck bed, or just that they want to save money or space. Our pick for the best twin mattress for adults is the Allswell Hybrid.

This a durable, supportive, coil mattress that’s made in the USA, but sells for far less than you’d expect. Last we checked, a twin size bed sells for under $275 before discounts. You can check the current price and discounts on

Very solid mattress for the money

The Allswell Hybrid is a bit on the firmer end, sitting at about a medium-firm, but keep in mind that all beds soften with time. From the get-go, it will be best for back and stomach sleepers, but we could see heavier side sleepers being fine, as well.

It will also have a little bounce to it thanks to the support coils at the bottom. This means that the bed will be more resilient than your typical foam mattress and offers more support for heavier individuals.

Usually, budget beds are a no-go for folks weighing nearly 250 lb, but Allswell is the exception. This is a quality mattress with Walmart pricing. Not surprisingly, Allswell is actually owned by Walmart, though, as of early 2019, we haven’t seen any Allswell mattresses in Walmart stores.

Why Shop For A New Mattress

Sleep is a vital yet often overlooked component of a healthy lifestyle. Many people pay more attention to their diet and exercise routines but really sleep is just as important. Sleep plays an important role in regards to immune function, memory, cognitive learning, metabolism and other vital functions. Not only is sleep good for you but you also spend a lot of time doing it. After all, it’s estimated the the average human being spends close to one third of their life sleeping. With that said, one of the biggest factors in getting a good night sleep is having the right mattress. That’s what we are focusing on in this post – helping you find the right mattress, specifically those of you looking for the best twin size mattress.

A Little About Us

We know mattresses! Doesn’t matter what size, what material or what price range—chances are we’ve probably tested it. That’s what we do for a living and we take our job seriously. We’ve tested latex beds, memory foam beds, innerspring beds and all sorts of hybrid beds. By this point, we have a solid understanding of the different types of mattresses and how the differences between them translate to various body types, sleeping preferences, etc. This is important because our ultimate goal is to help you find the mattress that fits your particular needs. Buying a mattress is a big deal. It’s not like purchasing a new phone case that costs $15 that you’re hoping will last six months. A good (queen size) mattress will cost you north of $600-700 and should hopefully last you 5-10 years. That’s why it’s important to do research before you buy and why we take our reviews so seriously. We strive for our reviews to be clear, concise and helpful. If we like a mattress, we’ll let you know. Likewise, if there’s something that we don’t like, we’ll let you know. Our viewers/readers are what’s most important to us. But enough about the Slumber Yard team—let’s talk twin size mattresses on this fine day.

What Is A Twin Mattress?

It’s the smallest size mattress most bedding companies offer. To be more precise, it’s a mattress that is 39 inches wide by 75 inches in height. Basically, it’s a big, soft rectangle. Typically, a twin mattress (or even a Twin XL mattress) is not the ideal size for an adult, unless you’re simply limited in terms of space. You’ll mostly see children and teenagers sleep on a twin size mattress. However, we will occasionally see adults use a twin mattress. After all, a twin, as compared to other mattresses, is supposed to be one of a matching pair of beds (hence the name). These pairs are often used in hotels or guest rooms. Twin pairs also often used by couples who want to be close to each other but don’t want to share the same bed. Lastly, a little fun fact for you – In England, a twin size mattress is called a “Single” size mattress. The Nectar UK mattress that we reviewed, for example, is offered in a single, not a twin, even though they’re pretty much the same thing. Anyway, here’s a chart that shows the dimensions for all most common mattress sizes.

Finding The Best Twin Size Mattress

The title of this page says it all. We’re talking twin size mattresses, which is actually the smallest size bed most companies offer. And you’re in luck, most companies do offer a twin size, unlike a Twin XL or Full size, which are a little more hit and miss. Despite its smaller size, finding the right twin size mattress is just like shopping for any other size mattress – it’s going to come down to two primary factors – your body type and sleeping preferences. What exactly do we mean by that? Let’s dig in.

Body Type And Twin Mattresses

Your body type and how much you weigh make a huge difference in how you perceive a mattress. One particular mattress will feel unique to different people. There’s no one size fits all mattress. One person might think a mattress feels extremely soft but if you ask a different person about the same mattress, they might say the mattress is on the firmer side. That’s why it’s important to keep in mind your own body type when researching beds. That’s also why we employ a large testing team so we can get various perspectives about the same bed and then come to a conclusion about what type of person each bed is best for. For the most part though, heavier individuals (more than 225 pounds) will generally feel like most mattresses are on the softer side of the spectrum. That’s because they exert more pressure on the bed and tend to sink in a little more. On the other hand, petite sleepers (call it 150 pounds or less) will generally feel like most mattresses are on the firmer side of the spectrum. That’s because (you guessed it) they exert much less pressure on the bed and never really sink in.

Sleeping Preferences

How you sleep makes a huge difference in which mattress is right for you. What we’re primarily referring to is the position in which you sleep – side, back, stomach or all three positions (called combination). Side sleepers will generally want a softer mattress that provides quite a bit of pressure relief. A firmer mattress may cause discomfort around your hips, neck and shoulders (pressure points) when you’re on your side. However, if you are a side sleeper, it’s important you don’t get too soft of a mattress. You don’t want to sink so far down to where your spine is no longer properly aligned. On the other hand, stomach and back sleepers will generally want a mattress that is slightly firmer. It’s imperative when you’re on back or stomach, that the area under your hips and lower back is being properly supported. If not, back and stomach sleepers may experience some discomfort or even pain. Combination sleepers will want a mattress that is somewhere in between. They’ll most likely want to search for a mattress that lands somewhere near a medium firmness level.

Usually, other factors play important roles as well, such as edge support and motion transfer. However, those factors are more important for couples who share a bed. In the case of a twin mattress, we assume you (our your child) will not be sharing this bed. As such, we think body type and sleeping preferences are more important factors when shopping for a twin mattress.

Benefits Of A Twin Size Mattress

There are several benefits of getting a twin size mattress. The first is price – we’ll discuss this in more detail below. The second is its size. Twin size mattresses will fit in almost all size rooms. Let’s face it – queen or king size mattresses just don’t fit all rooms. We’ve all been there, whether it’s one of our own rooms or a room in a friend’s place, where you walk in and the mattress pretty much takes up the entire space. There’s no room for a dresser, a chair or even a nightstand let alone enough space to walk around. If your room fits that bill, maybe it’s best going for a smaller size mattress like a twin or twin XL. Another advantage is weight. It’s much lighter than full, queen or king size mattresses. This makes a twin mattress much easier to move and make. Larger size mattresses can easily require two to three people to move. Also, some larger size mattresses are so heavy that even the corners are hard to lift when trying to put a fitted sheet around them. With a twin size mattress, you won’t have these issues.

Typical Prices For A Twin Size Mattress

Prices for online twin mattresses generally range from around $300 near the budget-end all the way up to around $1,200 near the premium-end—and that’s without counting mattress coupons. For example, a twin size Tuft and Needle mattress will cost you $325, while a twin size Casper Wave will cost you around $1,100. Of course, if you’re just looking to fill out a guest room or an Airbnb, you could go even cheaper. We’ve seen the Lucid 10″ Gel-Memory Foam twin size mattress as low as $150 before.
