Online mattress buying guide 2020
Mattresses are expensive. Some of them cost up to $4,000-$5,000, and this price range is quite high for an average American to afford. The bad news is that if you are not a mattress expert, you'll probably spend more than needed on a high-quality mattress. The good news is: here, we'll make you as close to a mattress specialist as possible and help you save a good chunk of cash on a new mattress. Let's start at the very beginning.
How to buy the right mattress: Factors you should pay attention to
Choosing the right mattress is often an extremely time-consuming process. Here, you’ll find all the necessary information to save your time and money — and the first thing you have to know is the factors to consider when choosing the right mattress. After that, we’ll talk about each of these factors in more detail.
- Type of the mattress. Most mattresses fall into four categories: memory foam, innerspring, latex, and hybrid. There are also futon mattresses, but they are not that popular in the US and are usually bought for guests.
- Size. There are 5 main mattress sizes, such as crib mattresses (suit only babies); Twin and Twin XL-size mattresses (work best for single adults and teens); Full-size mattresses (the best option for single adults and couples); Queen (the most popular mattress size which works great for couples); King mattresses and California King mattresses (work great for couples who prefer more space and for couples with children).
- Price. Of course, a good mattress can't be cheap, but what is "too cheap" and "too expensive" when it comes to mattresses? You can find an affordable mattress under $200 (if it's twin sized or buy a premium mattress for more than $2,000, but the majority of good mattresses are in the $400-$1,000 price range. Typically, more expensive mattresses have better coil systems and thicker foam layers thus providing more comfort and support.
- Trial and warranty. The trial period is the amount of time during which you can test the mattress, return it to the retailer if you don't like it, and get a full refund. Most trial periods last for 100-300 days, and it's really a great option — because, well, there is no perfect mattress for everyone, so you won't necessarily love the mattress you've bought. As for the warranty, it's simple — most manufacturers offer 5, 10, 25, or even lifetime warranties that cover sagging (every manufacturer puts its own threshold) and physical defects such as broken coils. There are almost no warranties that cover the damage caused by the owner, e.g. damage that occurs when you move a mattress or discoloration caused by washing.
- Firmness. The most popular firmness is "medium" (5 on a scale from 1 to 10), but the right firmness of the mattress depends on lots of factors, such as weight of the sleeper, favorite sleeping position, etc.
- Thickness. The perfect thickness of the mattress also depends on such factors as weight of the sleeper, medical conditions, and personal preferences — most mattresses are 8-12 inches thick, but there are also luxurious mattresses that can be as thick as 20 inches and mattresses for guest rooms/youth beds (5-8 inches).
- Density. The density is the feature of memory foam mattresses — low-density mattresses feel softer and cost less, medium-density mattresses offer both comfort and support, while high-density memory foam mattresses provide great support and work perfectly for those who suffer from back pain.
- Edge support — provides support on the sides of the mattress. The better the edge support is, the less the mattress will sag on the edges, and the easier it will be for you to get up from it.
- Motion isolation — if you're a light sleeper who doesn't stay asleep during the whole night because of your partner's excessive movement, you need to buy a mattress that isolates movement properly. Memory foam and hybrid mattresses have the best motion isolation, while innerspring and especially futon mattresses are the products with the worst motion isolation.
- The pressure points. Different sleeping positions have different pressure points — if you sleep on your back, you may feel pressure on your heels, shoulders, and head; if you are a side sleeper, you may feel it on your ankle, knee, hip, and shoulder; if you sleep on stomach, you’ll feel that on toes, knee, hip, and chest. The right mattress doesn't create pressure points — it allows your blood to circulate properly. If the mattress is too hard or too soft, you will probably wake up with aches and pains, so it's very important to make the right choice.
- Heat retention — in simple words, that's when your mattress holds heat and makes you sweat at night. This problem is quite common for memory foam mattresses but it can be fixed with a cooling topper or with new gel-infused memory foam mattresses. However, innerspring and latex mattresses are still the best options for hot sleepers.
- Expected lifespan — most mattresses last between 7 and 10 years, but it depends on the materials and on the quality of the mattress, of course. When you are choosing a mattress, it's extremely important to ensure it will last for long — because the mattresses are quite expensive and no one wants to buy them every 2 or 3 years.
Now let’s consider some of these points in detail - briefly but exhaustively.
These mattresses are made with viscoelastic polyfoam that is usually called "memory foam" — this material can evenly distribute weight over the surface of the mattress which means such mattresses are great when it comes to contouring and relieving pressure. Memory foam mattresses are comfortable (because of the foam that provides great cushioning) and supportive (because there is usually a thicker lower layer that provides support). These mattresses are great for stomach sleepers and for side sleepers — they provide proper spinal alignment and relieve stress at the same time.
- Memory foam aligns the spine and reduces pressure points.
- These mattresses offer great contouring
- Memory foam is a good material for those who have arthritis/joint pain
- These mattresses are more quiet than innerspring and hybrid mattresses
- Can be very soft and firm, it’s possible to find the right firmness almost for everyone
- Such mattresses provide the best motion isolation
- Memory foam mattresses are not the best choice for hot sleepers because they retain heat better than other types of mattresses
- They are typically more expensive
- Off-gassing (chemical odor) is a very common problem
Innerspring mattresses contain small coils that can be individually wrapped in fabric or interwoven with a foundation. These mattresses offer great support and they are typically closer to the firmer side — it's extremely difficult to find a plush innerspring mattress. They are quite durable and can last 10-15 years which is an extremely good lifespan for a mattress.
If you don't like that sinking feeling and want to find a medium or a medium-to-firm mattress that provides good support, innerspring is what you're looking for. Such mattresses are perfect for back sleepers but if you are a side sleeper, you should be careful with them — innerspring mattresses are often too firm for those who sleep on the side. If you sleep on your stomach, you need a supportive medium-firm mattress, so an innerspring mattress is what you need.
- Provide comfort and great support
- Such mattresses work great for hot sleepers because of the air circulation
- A great choice for plus-size sleepers and for those who don't want to "sink" in the mattress
- These mattresses are quite cheap (not all of them, of course, but it’s possible to find a good innerspring mattress under $500)
- Innerspring mattresses are not the best in terms of motion isolation
- If you’re looking for a plush mattress, 100% innerspring is not what you need
That's what is usually called the best of both worlds. Hybrid mattresses usually have both wrapped coils and memory foam/latex layers on top — such a construction makes them both comfortable and supportive. Actually, most modern innerspring mattresses have a memory foam top layer, but hybrid mattresses have more foam and therefore provide even more comfort.
There are both soft and firm hybrid mattresses, but they all provide great contouring because of the foam layer. That's why these mattresses are a good choice for back sleepers and for those who suffer from back pain, as well as for side sleepers (again, because these mattresses offer both cushioning and support) and for stomach sleepers (thanks to the coils, a stomach sleeper will not sink in the mattress).
- Better motion isolation than isolation innerspring mattresses offer
- Reduce pressure on hips and shoulders greatly
- Best of both worlds — these mattresses provide both comfort and enhanced support
- A better choice for hot sleepers than memory foam mattresses because of breathability
- Provide better edge support than all-foam mattresses
- Hybrid mattresses usually last 8-10 years which is a good result (though not the best)
- If the quality of memory foam is low, the mattress will quickly sag
- These mattresses are a bit more expensive than the others
- Hybrid mattresses are heavier than other mattresses
Latex mattresses are made of latex (a type of rubber) with springs/foam. Latex is an eco-friendly material that is very responsible and bouncy. It's not like memory foam that may take 10 seconds to snap back into place when you press it with your hand — latex expands very fast after being pressed. This material doesn't provide great contouring which makes it a great option for the hot sleepers. Latex mattresses are also a good choice for back/stomach sleepers because this material doesn’t allow sleepers to sink in it.
- Natural latex doesn't hold heat so it's a perfect option for hot sleepers
- No off-gassing Natural latex mattresses are hypoallergenic and perfectly resistant to dust mites
- Natural latex mattresses typically have very a long lifespan (10-15 years)
- Comfort and cushioning provided by these mattresses are perfect for those who suffer from back pain
- For some users, latex is "too firm"
- Natural latex mattresses are quite expensive
- Not the best pressure relief
- Latex mattresses are not the best in terms of motion isolation
Customizable airbed mattresses a.k.a. smart beds
Adjustable air mattresses or airbeds are the most expensive mattresses on the market — but they are a perfect option for almost all types of sleepers. The most interesting feature of these mattresses is the adjustable firmness which means you don't need to choose the mattress of a right firmness level, you only need to adjust the firmness yourself. All these mattresses consist of multiple air chambers that improve air circulation and support the sleeper better than other mattress types.
- Most adjustable air mattresses have separated comfort zones for different parts of the body so you can adjust the firmness level to suit your needs
- Such mattresses are very durable
- Adjustable air mattresses work great for all sleeping positions and for both light, average, and plus-size sleepers
- Almost all these mattresses have at least 1 breathable layer or gel-infused memory foam layer so they work great for hot sleepers
- These mattresses use the top-notch technologies — smart sensors that deliver data to the app, smart pumps that provide optimum support, etc
- Most air mattresses isolate motion transfer properly, so they are a perfect option for couples
- Additional air chambers provide great pressure relief to the pressure points
- These are the most expensive mattresses on the market — some Queen-size adjustable mattresses with air chambers cost up to $5,000
- Because of air chambers, these mattresses are quite noisy
- Not all expensive air mattresses are available in a Twin size
Futon mattresses typically work as guest beds in the United States. These mattresses are made with compressed layers of cotton, wool, or latex, but their most important feature is that they are often placed directly on the floor. However, many Americans prefer placing futons on Tatami-style beds (platform beds made of wood) or on slat bed frames.
- When placed on a wooden slat platform, these mattresses provide great air ventilation
- Futon mattresses are great for those who prefer firm and medium-to-firm mattresses
- There are lots of futon types and materials, from latex to cotton
- These mattresses take very little space so they are perfect for small rooms
- Futons are much cheaper than memory foam, innerspring, hybrid, and latex mattresses
- They are thin and lightweight, easy to remove and to clean
- If your futon is placed directly on the floor, you just can't fall out of the bed!
- Almost all futons are made from 100% organic materials
- For certain types of back problems, sleeping on a hard surface is a good thing
- Many futons are only 5-6 inches thick, so they will flatten over time
- When it comes to comfort, futon mattresses are definitely not the leaders of the market. Because of their construction, they are just "average", not very comfortable — almost any decent memory foam, innerspring, latex, and hybrid mattress will feel much more comfortable than a futon
There are plenty of mattress sizes that are available to buy right now in almost any shop online or offline. You can even order some rare sizes, although they are so big that you should have a really big room to place a bed with a mattress like Alaskan king (which is 108x108 in) there.
Below you can see two tables with popular and not so popular mattress sizes - choose the one that suits your needs.
Popular mattress sizes
|Twin||38x75||Children and single adults|
|Twin XL||38x80||Single tall adults who don't have enough space in a room. 2 mattresses of this size placed side by side make a standard king mattress, so it's a good option for partners who have different firmness preferences|
|Full||54x75||Single sleepers who prefer wider beds or couples who don't share the bed with children/pets|
|Queen||60x80||Couples with and without a child or a pet. The most popular size in the US|
|King||76x80||Two adults who want to have a lot of personal space and for two adults with a child|
|California King||72x84||Very tall sleepers or those who prefer very long mattresses. Only for relatively big bedrooms (bigger than 12 feet by 12 feet)|
Not the most popular mattress sizes
|Small Single||30x75||A child who has outgrown a crib and for teenagers under 6 feet|
|Wyoming King||84x84||For couples who find a California King size too narrow|
|Alaskan King||108x108||For those who share the bed with more than 2 children and for those who don't care about the price — such mattresses cost up to $5,000|
|RV||Typically the same size but a few inches shorter or narrower||For those who need a mattress for an RV, obviously. RV mattresses come in a lot of dimensions, from Twin to California King, and they are usually a few inches shorter than the “standard” size|
Firmness, thickness, and density: difference and how to choose
These are the most important factors to consider, as they determine how you will feel lying on your mattress. Have a look at the tables below and remember the preferable firmness, thickness, and density of your future mattress.
You should choose firmness considering your weight and sleeping style. Heavier sleepers should pick medium firm and firm mattresses, lighter sleepers can buy any mattress they want and that are recommended by their doctors (if needed, of course.) In the table below you can find all the essential information on mattress firmness and sleeping styles - find your one and enjoy a comfortable night’s sleep.
Extra-firmNo sinking, no conforming at all. Such mattresses are very hard to find and the majority of people don't actually need them because of that "board-like" feel
|Firmness||What to know|
|Extra soft||Extremely plush and sinkable mattresses that are very rare to see. Unfortunately, such mattresses can cause muscle pain and stiff back|
|Soft||Plush mattresses that work well for side sleepers because of the sinkage that contours the pressure points. Stomach and back sleepers need more support than plush mattresses usually offer|
|Medium||80% of sleepers prefer medium-firm mattresses. The point is, these mattresses are the best choice for stomach and back sleepers and they work well for side sleepers as well. Medium-firm mattresses have a good level of support without sacrificing comfort|
|Firm||More support, less sinkage and comfort. These mattresses keep the body straight and reduce pressure on the circulation system. However, hard mattresses are not the best choice for people who suffer from back problems|
|Extra-firm||No sinking, no conforming at all. Such mattresses are very hard to find and the majority of people don't actually need them because of that "board-like" feel|
In simple words, thickness is the height of your mattress which is determined by the number and thickness of layers it consists of. Mattresses usually have cover, support layer, and comfort layer, and their quality will influence your night’s sleep. Have a look at the table below to find out if you need a thicker or a thinner mattress, and what mattress thickness to choose for your family members.
|Thickness||What to know|
|2-5 inches||Extremely low profile mattresses that are typically used for cribs. Such mattresses are not as comfortable as the thicker ones and they are quite rare|
|5-8 inches||Not the most comfortable mattresses, but they are space-saving and can be used in a small bedroom. They are cheaper than 8+ inch mattresses, they are a good choice for shorter sleepers who don't want to climb into their bed, they work great for camping, RVs, sofas, etc|
|8-12 inches||8-12 inch mattresses usually have several comfort layers and a base layer that provides support, which means they are much more comfortable than thinner mattresses. 8-12 inch mattresses fall in a mid-price range and they are available in all firmness levels, material types, and sizes|
|12-16 inches||Good choice for heavier people and for those who want to get even more comfort. Thick mattresses usually offer more support than the thinner ones because of zone support. These mattresses are also more durable. It's very important to check if you have problems with getting in and out of a thick mattress before buying it. Obviously, such mattresses are more expensive than the ones from the previous category|
|16 inches and more||These mattresses are for those who weigh more than 300 lbs. They are very expensive, most of them are extremely comfortable, but they are not actually the "best" mattresses — thus, they don't work well for older people because it's hard to get in and out of a thick mattress and they take up too much space so they should not be installed in small bedrooms|
Density (only for memory foam mattresses)
Density is a measurement of how heavy the memory foam is compared to its size and it determines the firmness of the material. To calculate the measure of a memory foam mattress the manufacturer takes 1 cubic foot (12x12x12) of the foam and weighs this piece — say, if it weighs 5 lbs, the density of the mattress is 5 pounds per a cubic foot. The absolute majority of memory foam mattresses have 3-6 lbs/ft³ density. Let's see what it means for you as a buyer.
|Density||What to know|
|Low (3 lbs/ft³)||Feels very soft and provides that sinking feeling, works well for lightweight sleepers and children. Such mattresses are usually quite affordable (because less foam is used) but not very durable|
|Medium (4-6 lbs/ft³)||Better support, higher price, good airflow, a good choice for people with an average weight. Side sleepers will love the mattresses with such density, but not back sleepers (the level of support isn't high enough)|
|Medium||80% of sleepers prefer medium-firm mattresses. The point is, these mattresses are the best choice for stomach and back sleepers and they work well for side sleepers as well. Medium-firm mattresses have a good level of support without sacrificing comfort|
|High (6+ lbs/ft³)||The best support, works great for side sleepers and for plus-size sleepers, good contouring. These mattresses are more durable than medium and low-density ones, but they are not the best choice for hot sleepers|
Average mattress prices
Memory foam and innerspring mattresses fall under the middle price range category. Hybrids and latex mattresses are usually more expensive - they are of lux quality, although you still can find affordable latex and hybrid mattresses or get a good discount if you make a purchase at the right time.
|Mattress type||The average price range on Twin size||The average price range on Queen size||What influences the price|
|Memory foam||$300-$600||$600-$1,200||Density, thickness, gel-infused cooling layers|
|Innerspring||$250-$500||$500-$1,000||Coil type, thickness,, the quality of the comfort layer|
|Latex||$400-$600||$700-$1,400||Type of latex (natural/synthetic), thickness, type of the mattress (all-latex/hybrid), organic certifications|
|Hybrid||$500-$800||$800-$1,400||Thickness, the quality and density of the memory foam, the quality of the coils|
|Airbed||$1,500-$2,000||$3,500-$5,000||Number of comfort zones and air chambers, innovative technologies (sleeping tracking, body pressure map, etc), thickness of the top comfort layer|
|Futon||$100-$200||$150-$400||Materials, the frame (futons usually come with a wooden or metal frame)|
Buying a new mattress: guide on online and offline shopping
You need to make a decision here, so let's use that classic "pros and cons" decision-making technique and see which one is better. Let's start with offline shopping.
- You can touch the mattress and test it before buying
- If the salespeople are professional, they can guide you and tell you everything about the mattresses
- It's just more fun than online shopping
- Lying on a bed for a few minutes is not enough to understand if this mattress will work for you or not — all the mattresses have a so-called "break-in" period so you'll have to spend at least 7 days to adapt to a new mattress
- Offline mattress stores usually don't offer a trial period
- Purchasing a mattress offline is usually more expensive than doing it online It's time-consuming
- Salespeople can be quite annoying and pushy sometimes
- Online shops offer tons of mattresses, more than offline stores It's fast, convenient, and cheap — there are no middlemen, no store rent, no employee salaries, etc
- Online stores offer long trial periods, usually 100-300 nights. You can test the mattress and return it, it’s usually free
- The customer support can answer all your questions without pushing to close the sale A wide selection of delivery options e.g White Glove delivery
- You can't try your new mattress before buying
- Not all manufacturers offer free returns during a trial period
- Not all customer support specialists are as professional as salespeople in the best offline stores
