Frequently Asked Questions
We build our mattresses in the USA using eco-friendly materials certified by CertiPUR-US®. This allows us to ship to most homes within the lower 48 states in a matter of days – and for free!
No. We designed our mattresses to keep you cool and comfortable all night. But we get this question a lot, because overheating is a common problem with traditional memory foam. The less-breathable, petroleum-based foam traps heat.
Amerisleep mattresses are different. We use our proprietary Bio-Pur® material inside. Bio-Pur® comes from partially plant-based material instead of 100% petroleum. And Bio-Pur® also has an "advanced open-cell structure" that wicks away warm air and keeps you cool.
We guarantee you will stay cool and comfortable in an Amerisleep mattress. That's why we offer a risk-free trial for 100 nights. If you don't love everything about your Amerisleep mattress, we'll give you a full refund.
Most of our customers experience deeper, more comfortable, and more restful sleep from the very first night. But in some cases, you may need time to adjust to the support of your new mattress.
It may seem counterintuitive, but switching to a mattress that gives you proper support can actually cause discomfort at first. Here’s why:
Chances are you had your previous mattress for years or even decades. During that time, you developed what are called “sleep postures,” meaning your body got used to sleeping in a certain way — even if it didn’t have proper support.
If your body is used to sleeping in a certain posture for years, any change can cause discomfort at first. Even if you’re actually getting better support than before.
That’s why it may take some time to adjust to your new Amerisleep mattress. It’s designed to give you proper spinal alignment and pressure relief. But if your sleep postures aren’t used to it, your body will need time to adjust. Once you do though, you’ll be sleeping even better than before.
While it’s not required, we strongly recommend you use a mattress protector. We want your Amerisleep mattress to last for decades. (That’s why we offer a 20-year warranty.) And we would hate for an accidental spill to ruin your new mattress.
If you need to wash your mattress cover, it has a zipper for easy removal. Wash it with a cold and gentle cycle, and hang it to air dry.
You do not need to flip or rotate your Amerisleep mattress. The side with the white cover should always remain facing up. Because unlike innerspring mattresses, foam mattresses do not get indentations from repeated use. So you do not need to flip or rotate them.
Shipping in the continental US is always free and so are returns. We believe in fully transparent pricing. There are no restocking penalties, surcharges, or other hidden fees.
When To Replace Your Old Mattress
A high-quality mattress shouldn’t need replacing for a while as long as you take good care of it. Of course, the lifespan of your mattress depends on its materials and the quality of the workmanship, too. How can you tell if your mattress is really going to last?
First, read the company’s warranty. The mattress industry’s standard warranty length is 10 years. Because most mattresses need replacing within 7-10 years, this warranty length protects customers against any manufacturing defects or issues that may come up. The warranty is one way to tell how long a company is willing to stand behind their product— keep in mind that so-called limitless warranties, such as lifetime warranties, are more of a marketing ploy than a guarantee that the product will last for your lifetime.
Instead, look for a mattress with a warranty lasting between 10-25 years. Most warranties between 10-25 years are prorated, meaning the customer assumes some responsibility for the cost of repairs or replacements during the second half of the warranty.
Next, consider the mattress materials and mattress type. Studies have shown that innerspring beds have the shortest lifespans, with customers reporting sagging within 5 years of purchasing. What’s more, innerspring mattresses with super-plush pillow tops break down even faster, perhaps due to the lack of firm support beneath the soft comfort layers.
The longest-lasting mattress types are hybrids, memory foam, and latex— latex beating them all with an average 15-year lifespan. These three mattress types are usually created with reinforced core layers to avoid any premature sagging.
If your bed is getting old but it still works well, no need to replace it! However, if you’re experiencing one or more of these problems, it may be time for a new bed:
- Deep sagging or indentations cause you to feel “stuck” or trapped in the bed
- The mattress takes a long time to recover after being compressed
- You can feel the stiffer base layers when lying down (either the hard foam foundation or innerspring coils)
- You wake up with shoulder, back, hip, or neck pain
- You get a full night’s rest but you wake up feeling tired
- The mattress is trapping heat, causing you to sleep hot
- The mattress is irritating your allergies or breathing
- The mattress does not isolate motion, so you can feel your partner’s every move
Gel Memory Foam vs. Memory Foam
No doubt you’ve heard of memory foam mattresses in your search for a new bed—it is by far one of the most popular mattress types on the market today, thanks to its pressure-relieving qualities and fast response time. It contours easily to any body type and is virtually noiseless, unlike the squeaky innerspring beds of the past.
Memory foam is viscoelastic, meaning it takes on viscous and elastic properties when heat or pressure is applied to it. It springs back fairly quickly and conforms closely, eliminating motion transfer and pesky noises. Memory foam was first developed in the 70s for NASA, but eventually, it became a staple in the mattress industry thanks to its luxury feel for an affordable price. Thanks to the mattress in a box revolution, memory foam has only become more sought-after.
However, memory foam has a flaw: because of its texture, it easily traps body heat, so some users report waking up hot, uncomfortable, and sleep-deprived. To fix this problem, memory foam mattress brands have developed foam with cooling technologies.
One of the most popular cooling mattress types is gel-foam. This mattress type is either infused with gel, dotted with gel beads, or the gel is partially mixed in with the foam during manufacturing, creating “gel-swirls.” The gel acts as a heat magnet, drawing high temps away from the body and keeping the mattress cool.
Other cooling technologies include advanced open-cell foam, like that used in Amerisleep mattresses. This foam promotes airflow and reduces the chance of your bed becoming a heat trap.
Choosing a mattress size isn’t as straightforward as it seems. If you’re simply replacing your old mattress, you might not think twice about the size you need. However, if you’re upgrading, downgrading, or buying a whole new bed set, choosing the best-sized mattress for your needs can be tricky.
Twin and Twin XL
Twin and twin XL mattresses are perfect for single sleepers. Twin mattresses are a go-to for parents whose children have finally outgrown their crib. While twin XL mattresses are great for children of all ages, teens, college students, and single adult sleepers.
The difference between twin and twin XL mattresses lies in length. Twin mattresses measure 38 inches by 75 inches, while twin XL mattresses measure 38 inches by 80 inches. The five extra inches of legroom make the Twin XL suitable for adults.
Full and Queen
Full and queen mattresses are a comfortable option for single sleepers who have the room in their bedroom to accommodate a larger mattress. They’re great for those who share their mattress with a pet or child, too, as they offer a little more wiggle room than either twin sizes.
Full mattresses measure 54 inches by 75 inches, while queens are 60 inches by 80 inches. Queen mattresses can work for couples, but fulls are usually too small to accommodate two adult sleepers.
If you’re a single sleeper and prefer the extra room to sprawl out, choose a full or queen over a twin or twin xl. Just make sure your room is large enough to fit a bigger mattress. Alternatively, if you intend on sharing your mattress with a partner, choose a queen over full or other smaller sizes.
King and California King
While queen mattresses can fit two sleepers, most couples opt for a king or California king-sized mattress. It’s a common misconception that the California king is bigger and better than the standard king mattress, when in reality, they offer the same amount of sleeping area. Let’s talk about where they differ.
King-size mattresses have dimensions of 76 inches by 80 inches and California kings measure 72 inches by 84 inches. California kings are 4 inches longer than the standard king, but they’re also four inches narrower. If you're taller individual, a California king is more your speed; but if you value the space to sprawl more than legroom, you’ll want to stick with a standard king.
It’s not always easy to find a comfortable mattress for two people, as everybody has varying sleep needs. If your partner wants a firm bed and you want a softer mattress, it can be challenging to find a good middle ground—which is why split king mattresses are now offered.
Split king mattresses are really just two twin XL mattresses placed side by side on a bed frame. A twin XL measures 38 inches by 80 inches, and a King measures 76 inches by 80 inches. When you do the math, two twin XL mattresses side-by-side have the same dimensions as a standard king.
Even though split kings are two separate mattresses, they’re designed to have a seamless feel; so you won’t feel like you’re rolling onto a different mattress if you end up sprawled out onto your partner’s side of the bed.
Split king mattresses allow couples with different sleep preferences to choose their “best mattress” for their side of the bed.
A mattress can be an expensive investment, and many of us wait for a big mattress sale to take the plunge. With the addition of sleep trials, buying a mattress comes with less risk than it used to. However, there’s nothing wrong with taking advantage of big sale weekends when you’re ready to get a new bed! Many of these sales begin early and go beyond the actual holiday, giving you plenty of time to take advantage of discounts and promotions.
Best Mattress Sales:
- Presidents Day Mattress Sale
- Black Friday Mattress Sale
- Labor Day Mattress Sale
- Cyber Monday Mattress Sale
Keep in mind that some promotional deals will appear without any link to a big sale weekend—in some cases, these promotions are a marketing tactic and they don’t really offer you a great deal. For example, a common promo offered at brick and mortar mattress stores is “buy one bed, get one free.”
At first glance, this seems like a great deal—who doesn’t want a free bed? However, BOGO deals come with certain restrictions and you’re usually limited to getting a cheaper, low-quality model for free. This will only take up extra space in your home without offering much comfort or value.
Maybe you’re deciding between a few different mattresses or brands. Ask yourself if you would purchase the mattress even if it wasn’t on sale—if the answer is yes, chances are you’re confident in the quality and durability of the mattress. However, if you aren’t sure the mattress is worth the cost, even (and especially) on sale, it’s time to look elsewhere.
Using the Right Foundation
Once you’ve found the perfect mattress, it’s time to pick a compatible foundation. When choosing a foundation or base, use the correct one outlined by the company’s website. Online mattress companies will specify which foundations are compatible (or not) with their mattresses since using your mattress on the wrong foundation can void your warranty.
Foam beds don’t need a box spring like innerspring beds do, but they still need to be used on the right foundation to avoid any damage, sagging, or trapped heat. For instance, if you plan on using your new foam mattress on a slatted base, make sure the slats are no more than 3 inches apart—gaps any wider may cause premature sagging.
Additionally, placing your foam mattress on a solid, closed surface without slats can minimize airflow, so if you’re prone to sleeping hot, consider a slatted base. Most people with a solid platform foundation don’t experience these issues, but it is something to consider. Your foundation is more than a piece of bedroom furniture—and choosing the wrong one can change the feel of your mattress for better or worse.
What about adjustable bases? Perhaps you think an adjustable bed frame is only for someone with specific health conditions like sleep apnea or poor circulation, but they make anyone’s night much more comfortable. They allow you to customize your sleeping position, and some come with extra features like USB ports, nightlights, and apps you can sync with your phone.
Mattresses for Specific Health Conditions
If you suffer from chronic back pain, inflamed pressure points, or sleeping too hot, you know how much these and other conditions can interrupt your sleep. A high-quality mattress isn’t a cure-all, but it can certainly help.
For those who deal with back, shoulder, or neck pain, a medium or medium-firm mattress will give the right balance of even support and cushioned softness for the best night’s sleep. An extra firm mattress can lead to a build-up of pressure points. Memory foam is one of the best mattress types for pain-sufferers because it alleviates those all too familiar pressure points.
Those who sleep too hot should opt for gel memory foam mattresses or other types of memory foam infused with cooling elements like graphite, charcoal, or copper. Consider also your bedding: use natural fibers such as cotton, bamboo, or Tencel that allow for more airflow and moisture-wicking.
Your preferred comfort level depends on your sleeping position, weight, and whether or not you sleep with a partner. Amerisleep offers five different firmness options to accommodate a variety of preferences, so you shouldn’t have any problem finding the right mattress.
Firm (AS1): Firm beds are more suited for back and stomach sleepers because they keep the posture neutral without allowing for any sinkage. A firm memory foam mattress like the AS1 has stiff, dense foam layers in the base to keep the sleeper on the bed, not “in” it.
A firm bed typically has a thicker layer of stiff support foam than softer models—therefore, a heavyweight sleeper should avoid firm beds, since they will most likely feel that higher density foam as soon as they lie down. If you’re heavy and prefer a firmer bed, we suggest the AS2.
Medium-Firm (AS2): Medium-firm mattresses are a great in-between option for anyone who likes a sturdy, supportive sleep surface with just a small bit of cushioning. Medium-firm mattresses work best for stomach and back sleepers because like firm beds, they don’t have a lot of give. No matter your sleeping position, your goal should be to keep your posture aligned all night long, minimizing your risk of waking up in pain.
Medium (AS3): Medium feel mattresses are some of the most popular types because they appeal to the most common sleeping positions—side and combination—and they’re usually the most comfortable firmness for couples with differing sleep preferences. Average weight side sleepers typically like this “medium” feel because it cradles the preferred side without causing pressure build-up or numb limbs. In other words, it’s the perfect balance of support and softness.
Most companies market their “medium” mattress as somewhere between 5-7 on the mattress firmness scale (1 being the firmest and 10 being the softest).
Medium-soft (AS4): Medium-soft mattresses appeal to side and combo sleepers who need a thicker comfort layer than most medium models provide. Lightweight or average sleepers often enjoy medium-soft beds because they give just the right amount of cushioning without sinking too deeply, risking misalignment.
Soft (AS5): Soft and plush mattresses are best for both heavyweight and average-weight sleepers who like a thick, soft bed (the Amerisleep AS5 is the thickest model in their lineup at 14 inches). The best mattress for side sleepers is one that helps them maintain a neutral position while enjoying the contouring, soft foam.
What is the best type of mattress?
It depends on your preferences! Memory foam is a popular choice because it offers pressure relief, is quiet, minimizes motion transfer, and conforms closely to the body. However, it poor quality foam can sleep hot.
Latex foam is an eco-friendly alternative to memory foam. All-natural latex is produced from the sap of a rubber tree and manufactured using either the Talalay or Dunlop method. Neither one is better than the other, but they each produce a slightly different feel.
Talalay is softer and Dunlop is more dense and firm. Latex lasts a very long time—some users of latex mattresses report a lifespan of up to 15 years. Note that this long lifespan accounts for the extra cost—latex is one of the more expensive mattress types.
Innerspring mattresses have been around the longest, and as such, they’ve gone through lots of iterations. Older models are pretty uncomfortable, but most innersprings on the market today are built with steel coils in the base and a quilted Euro-top or poly-foam top layer. Some innersprings, as well as hybrids, have wrapped coils in the base to minimize motion transfer.
Which mattress is best for back pain?
For years, the pervading wisdom held that soft mattresses with ample cushioning layers were best for back pain sufferers. However, recent studies have shown this is not the case. A too-soft mattress can cause the user to sink down into the bed, leading to more pain. These studies concluded a medium or medium-firm mattress is best mattress for back pain because of their even support and balanced cushioning feel.
What kind of mattresses do hotels use?
Most hotels use innerspring mattresses, although there is no “universal hotel mattress.” Every hotel chain uses different brands and mattress types, so it’s best to ask the hotel chain where they get their mattresses if you’re curious and want to replicate the experience at home.
Hotels invest a lot of time and money in finding the most comfortable mattresses. After all, a large part of the hotel experience is sleeping comfortably, and if customers don’t get that, they may not come back. Bear in mind that hotels also use high-quality bedding, pillows, and keep their rooms temperature-controlled—all things which contribute to a comfortable sleep experience.
Why are mattresses so expensive?
We spend a lot of time in bed—one-third of our lifetimes, to be exact. If you want a mattress that lasts, you should expect to spend more than you did the uncomfortable futon you slept on during college. What’s more, a poorly constructed, cheap mattress can exacerbate back pain, existing injury, allergies, and sleep disorders, leading to a poorer quality of life.
With the advent of memory foam, comfortable, pressure-relieving mattresses are within the reach of most budgets. You shouldn’t have to sacrifice good sleep just because your mattress budget isn’t sky-high.
To ensure you get your money’s worth, maintain your mattress properly. Keep a protector or encasement on its surface to deter any bed bugs, dust mites, or spills or stains from coming in contact with the bed.
What is the best mattress for the money?
Perhaps one of the biggest determinants of the mattress you choose is your budget. Every customer wants to ensure the mattress they’re investing in will hold up over time. High-quality memory foam mattresses typically cost between $800-$1800 in a queen size. Specific factors will influence the cost, such as the warranty, extra mattress features such as cooling gel or built-in lumbar support, and the mattress materials.
For instance, a basic two-layer foam mattress will probably fall within the lower-priced range, while softer models with more materials and more foam layers will cost more.
The mattress warranty tells you how long a company is willing to stand behind their product—the industry standard is a 10-year warranty. A warranty shorter than that could be a red flag. Memory foam beds last anywhere from 7-10 years, and some last longer if maintained carefully.
Read all of the warranty conditions before purchasing so you know exactly what defects you are protected against—most companies cover sagging or indentations up to a certain depth (usually about 1 inch) as well as tears in the cover or defective zippers.
Is memory foam safe?
If you’ve researched memory foam mattresses at all, you’ve probably come across this question. Memory foam is made with polyurethane, which comes from petroleum. It’s impossible to make memory foam completely free of polyurethane, but some brands have begun to replace some of the petroleum with plant-based oils. This makes the mattresses more breathable, minimizes the off-gassing odor so often associated with foam, and it’s better for the environment.
Look for CertiPUR-US® certified foams free of PBDEs (toxic flame retardants), phthalates, formaldehyde, ozone depleters, and heavy metals.
Which size of mattress should I buy?
Average-sized adults typically choose a full, queen, or king-size mattress. A queen mattress is the most popular size among average-sized couples, but if you toss and turn a lot, a king-size mattress is a roomier option as well.
The ideal mattress size depends on the size of the person or people sleeping in the bed—a king mattress is large enough for most, but a California king adds a little more length than the king-size, so it’s best for tall sleepers.
Twin mattresses are best for children or teenagers, but once they hit a growth spurt, it might be time to transition to a twin XL or a full mattress.
When should I use a mattress topper?
If your mattress is getting older and you’re not quite ready to buy a new one, consider a mattress topper. Foam toppers can alleviate pressure points caused by sagging in your old bed, and many of them are made with cooling technologies such as gel, regulating your temperature and adding an additional comfort layer to your once uncomfortable mattress.
A mattress pad is not the same thing as a topper—typically, mattress pads are thin coverings to protect the mattress against any liquid stains. They may have a bit of cushioning, but not as much as a topper. If you’re more concerned with protecting the mattress surface, choose a pad or a mattress protector. A topper is mainly meant for added comfort, not protection.
