If you're going to spend a third of your life in bed, it better be on a pretty great mattress. But, while finding the best mattress for you was once a fairly straightforward exercise, maybe involving a trip to the local mattress store to lay on a pillow top while a salesperson encouraged you to get comfortable, today's mattress buying efforts look a little bit different. 

The good news? You can probably find the right mattress without even leaving your sofa (or even getting out of bed). At the same time, holy moly are there a lot of options out there. From the dozens of direct-to-consumer mattress-in-a-box brands that have sprung up over the last decade, to the latest in innerspring coil technology, and the hybrid mattress that fall somewhere in the middle, there are endless options when it comes to choosing the best mattress. Which means finding the one to turn (in) to for the next seven (yes seven) years of your life can be a tad overwhelming. 

Not to worry! We took it upon ourselves to try out, test and research the best mattresses on the market in 2020. It was quite an enjoyable experience for us (zzzz), and all in an effort to help make your decision easier.

If this is the first time that you've ever bought a new mattress, be sure to jump down the page to our 10-step guide on how to buy the best mattress for you, where you'll find all the information you need to know. 

Not sure you're ready to spring for a whole new mattress? A mattress topper can be an effective way to make your current mattress more comfortable. Check out our guide to the best mattress topper for more. 

An overview of the best mattress picks for 2020:

The best mattress 2020

Best mattress 2020: Emma mattress

1. Emma Original Mattress

Best mattress 2020

Specifications
Size: Twin - Cal king
Depth: 10"
Type: Comfort foam/memory foam
Firmness: Medium-firm
Reasons to buy
+Zoned support+Perfect temperature control+Medium firm for firmness+Good motion transfer
Reasons to avoid
-Too hard for some side sleepers

The Emma Mattress is a European favorite that's only recently made its way stateside, and boy are we glad it did: it's taken our top spot as the best mattress all around. (In fact, we're almost certain that the Emma mattress is the reason Europeans supposedly get five hours more sleep per week, on average, than Americans.)

Get to know Emma, below.

Who will the Emma suit?
This is a medium–firm people pleaser which is complete with memory foam (the second of three incredible layers of foam) and zoned support to keep even the most squirmy of sleepers truly content. It's available in a full range of sizes, from a twin to a California-king, but because it offers great motion transfer and optimal temperature control, this is ideal for couples too. While side-sleepers may prefer something a little less firm, our tester (who sleeps on her back and prefers a firmer mattress), really enjoyed the Emma Original and would recommend it to anyone who likes to indulge in complete memory foam comfort. In our opinion, it's the best pick for those who tend to move a lot in their sleep. The motion transfer on this mattress is divine. You'll hardly know your restless partner is there.

What is the Emma like to sleep on?
There pretty much nothing we don’t like about this mattress. It’s easy to switch positions, and comfortable in whichever position you favor for that matter. We’d rate it towards the firmer end of medium, but it’s certainly not rock solid. The mattress is evenly supportive across the entire surface, so there’s plenty of room to spread out. 

Special features?
The breathable, removable top cover can be washed on a hot cycle to effectively kill dust mites and bacteria. 

Another reason we love it? Despite its European roots, the American version of the Emma mattress is made in the USA.

Materials?
Three layers of foam. The top layer is an elastic foam called Airgocell, which brings you pressure relief. The memory foam layer is next and, like all memory foam, keeps you comfortable in any position. The base is made from Cold Foam that supports the above layers, as well as you. 

What do you get for your money?
A 100-night sleep trial, no questions asked, 10-year warranty and free delivery, usually within one to three business days.

Best firm mattress: Casper Mattress

2. The Casper Mattress

The best mattress for firmness

Specifications
Size: Twin - Cal king
Depth: 10"
Type: Comfort foam/memory foam
Firmness: Medium
Reasons to buy
+Cool, comfy foam+Medium firmness+Good for all sleep positions+Good for motion transfer+Comes in a box
Reasons to avoid
-Usual chemical smell when you unpack it, but it will fade

This award-winning dual foam mattress scores big on comfort and coolness, particularly with side sleepers who suffer with joint pain.

What is the Casper like to sleep on?
The Casper mattress is softer than some memory foams on the market, making it the best choice for side sleepers. Your hips and shoulders sink lower than the rest of your torso, providing an ergonomically aligned spine. There’s little motion transfer so you won’t notice your partner tossing and turning in the wee hours. The cooling layers also make it breathable, which again aids undisturbed sleep. The majority of Amazon’s reviewers are thrilled with their Casper, revealing that they wake up feeling fresh and revived.  

Special features?
The top cover zips off for easy cleaning (throw it in the wash on hot) and there are handles for easy maneuverability – you’ll be amazed how many mattresses don’t have this simple but extremely useful feature. It comes in a full range of sizes so you’re sure to find the perfect fit. There’s even a Casper bed for your dog!

Materials?
This is a four-layer mattress that is all tucked neatly within a soft cover. The top layer is an open-cell foam that provides immediate bounce and has cooling properties. Next is a high-density memory foam layer, which supports your pressure points. The Transition Layer deals with even weight distribution, and the final layer acts as a supportive base that helps keep everything stable. 

What do you get for your money?
A 10-year limited warranty, free delivery and returns, plus very good customer service, according to the reviews. Look out for discount codes on the Casper website and social media – typically around 15 percent.

Best organic mattress

Specifications
Size: Twin - Cal king
Depth: 11"
Type: Hybrid
Firmness: Medium to Firm
Reasons to buy
+Sustainably harvested latex rubber foam+Best for back and side sleepers+Medium to firm for firmness+No fire retardants+Handmade in Los Angeles
Reasons to avoid
-One of the most expensive mattresses on our list

The Avocado Green mattress takes the title of best organic mattress for a handful of key reasons. For one, it's an eco-friendly option from top-to-bottom, made with GOTS-certified organic cotton and wool, and sustainably harvested latex foam. It's also handmade in Los Angeles, and is uncompromising when it comes to quality. It might be one of the most expensive mattresses on our list, but well worth the price if it's in your budget.

Who will the Avocado mattress suit?
Side- and back-sleepers, and those with chemical sensitivities or allergies; the mattress is made without fire retardants, petroleum-based foams or chemical adhesives so the off-gassing period typical of other foam mattresses is nil. 

What is the Avocado mattress like to sleep on?
The Avocado mattress sits on the firmer side of medium; the brand rates it a seven out of 10, with 10 being the firmest. A soft top layer made from latex foam adds comfort to a supportive base made of up to 1,414 individually tuned, tempered steel coils (the exact number depends on the size of the mattress you order). The mattress is broken up into five ergonomic "zones" designed to keep comfort at a premium and motion transfer at bay.

For those who prefer a softer feel, the mattress is also available with a plush cotton pillow top.

Special features?
Instead of chemical flame retardants, the Avocado green mattress meets U.S. flammability standards with an all-natural fire retardant: wool. It's also one of only three mattress brands in the world to be MADE SAFE® Non-Toxic certified.

Materials?
The base of this two-layer hybrid mattress is made from fabric-wrapped innerspring coils. The top layer is made of latex foam foam covered in a GOTS-certified organic cotton casing.  

What do you get for your money?
A 100-night trial, and a 25-year guarantee, one of the longest of any we reviewed.

How to buy the best mattress for you

Considering a new mattress? If you haven't replaced yours for seven years (or more), or if you’re at the point where you are waking up in the morning feeling feeling achy or uncomfortable, now is the time for an upgrade. Follow our comprehensive guide to how to choose a mattress for a better, more restful night's sleep.

Key points to consider when buying a new mattress:

  • Work out your sleep position: if you're a side sleeper, you'll need a softer mattress (think memory foam or hybrid) than back or front sleepers
  • Are you heavy or light? Heavier people tend to find firmer mattresses comfortable; lighter people need a softer mattress they can sink into a little;
  • Tend to toss and turn, or have a partner who does? 'Good motion transfer' is the phrase you're looking for in a mattress – most of those above have that (memory foam or hybrid mattresses usually more so than traditional spring mattresses);
  • Back pain sufferers? Look at memory foam or a hybrid (which is foam over springs); 
  • Allergy sufferer? Consider latex as a filling (although memory foam/hybrids will be good for you too, as will a money-saving mattress protectors); 
  • Sweaty sleeper? Find a mattress made of breathable materials: most of those above have this type of filling.
  • Materials and certifications: Eco-friendly materials include latex, and organic cotton and wool. Or, look for labels like Certi-Pur US.
  • Budget: not everyone can splurge on a mattress, which is why we've included a range of models to suit all budgets; PLUS our clever widgets (seen throughout the article) display the best prices every day.

1. Use the free trial to test your new mattress

We'd never advise anyone to buy a mattress without trying it first. Back in the day, that meant going shopping and lying on mattresses in-store but honestly, the days of buying a mattress in-store are far behind us. Now, you can safely shop online and take advantage of the free trial with hassle-free returns. As the majority of the mattresses we've reviewed come with super handy 100-night+ sleep trials and/or one year to 10 year warranties, you're sure to find an option that has you covered.

2. Buy the best mattress for your sleep position

Are you a back sleeper, a side sleeper or stomach sleeper? Purchase your next mattress to suit how you sleep, and you'll be pain and ache free in no time. 

Side sleepers can experience achy joints, especially around the hips and shoulders. Opting for a softer mattress you can sink into is the way to go, with medium-soft the most recommended comfort grade. Other than our overall list topper, the Emma mattress, we recommend the Casper Hybrid for side sleepers.

Stomach sleepers might experience sore pressure points in the ribcage, knees, and elbows, as well as what’s alarmingly called 'general spinal discomfort'. You will find a firm mattress that supports you but has give for these sensitive points most comfortable. Our all-round best bet is TKTK, a medium mattress with a winning spring and latex construction. We also like the TKTK.

Back sleepers need to go for a middle ground for maximum comfort: not too soft, not too firm. Our favorite for back sleepers is the TKTK; it's also a good buy for side sleepers who prefer a slightly firmer sleep surface.

You also need to consider how things like your pillow impacts on your sleeping position and mattress choice, too. Use our guide to how to choose a pillow for your sleep position to get that right.

3. Get the right level of mattress firmness

One of the most important things to think about when purchasing a new mattress is getting the right firmness for you. Often it comes down to personal preference and whether you prefer a soft or firm feel; you just need to be confident that you have the correct support for the way that you like to sleep. Your weight plays a part, too: heavier people will find a harder mattress more comfortable than lighter people, who will usually fare better on a softer mattress. Here's a rough guide to what should suit you:

  • Soft medium: Ideal mattresses for side sleepers, as they let your shoulders and hips sink into the mattress while supporting the rest of your body;
  • Medium: If you sleep on your side but prefer the feel of a firmer mattress, choose medium support;
  • Medium firm: If you change position from your side to your back this is the best option;
  • Firm: If you prefer to sleep on your back or sleep on your stomach, choose a firm mattress, which will give you just the right amount of support;
  • Extra firm: Sometimes called an orthopaedic mattress, extra firm mattresses offer a very firm level of support. 

4. How to do a quick mattress comfort test

If you are testing out a mattress in-store, you can check if it might suit you by lying down and sliding a hand beneath the small of your back. If your hand slides in easily, the mattress is too hard; if you can't slide your hand in at all, it’s too soft.

Bear in mind, though, that the base you'll be putting the mattress on will affect how the mattress feels at home. For example, a box spring will make a mattress feel softer than a solid or slatted base. 

Is that rushed showroom test not assuring you that your new mattress is right for you? Or perhaps you're buying a new mattress online? This is where those 100-day, hassle-free return policies pull their weight – so double check what your retailer is offering when making a decision.

5. Choose the best mattress material for you

There's a mind-boggling array of mattress material choices but it's important to state that no one particular type is better than another; it's much more about what you'll find comfortable. Here's a quick rundown of the mattress types available:

Memory foam molds to your body's shape, and gives plenty of support, making it perfect for side sleepers or anyone with back pain. Newer memory foam mattresses have breathability built in – so look for this as a feature when buying. It's also good for allergy sufferers. Our top choices are the Casper and the Leesa.

Hybrid mattresses/sprung memory foam mattresses are constructed with a pocket-spring base and a memory foam top layer, so you'll get the responsiveness of springs plus memory foam support. Good for allergy and back pain sufferers. Our favorite is the Casper Hybrid.

Latex is durable and breathable; it tends to be on the firmer side, and is ideal for allergy sufferers thanks to its anti-microbial properties. It’s also a very durable material and can be expected to support you soundly for years. For a good combination of latex and pocket springs, we like the Naturepedic Organic Serenade.

Innerspring mattresses, made from individual springs in pockets of fabric, provide lots of support, whether you prefer a soft or firm sleep surface. They can also come with different levels of support on either side of a double for partners who prefer different levels of firmness. Our pick is the Saatva Classic Mattress.

Open spring mattresses are cheaper and lightweight, but less supportive and responsive; choose them for guest rooms.

Natural mattresses should not include polyurethane foam; rather, look for only natural fillings such as cotton, hemp, and flax, and it should provide an alternative to the chemical fire retardants that are used in other mattresses. A mattress that calls itself natural needn't be low-tech: advances in pocket spring technology mean that the days of squeaky, massive springs are over; new models use thousands of micro-springs that rotate as your body moves, so you should, at least in theory, be as comfortable sleeping on your natural mattress as on a foam or hybrid mattress.  

6. Pick the right mattress size

This will often be determined by the bed that you already have. However, if you are starting from scratch and looking to get a new bed and mattress then a good place to start is with the right size. 

If you are sharing a bed with a partner a queen is usually sufficient, but if you are someone who requires more space or is often disturbed in the night, then it may be wise to go up a size (if you have the space, of course). Ideally, your mattress should also be wide enough to allow two of you to lie side by side with your hands behind heads, without your elbows touching. Our guide to how to buy the best bed is useful in helping you to choose the right option for both your home and your lifestyle. 

As for mattress length, it should be 4" longer than the tallest person sleeping in it. So, if you're a strapping 6 footer, you'll be looking at a king size mattress as a minimum. 

The mattresses in our list range from 9" to 11" in depth. See how high your bed is and check the overall height of your bed isn't going to be an issue (especially if you have mobility issues and climbing into a high bed is a challenge).

Below are the most common US standard mattress dimensions:

  • Twin: 38" x 75"
  • Twin XL: 38" x 80"
  • Full: 53" x 75"
  • Queen: 60" x 80"
  • King: 76" x 80"
  • California king: 72" x 84"

7. Look at the mattress's additional features

It's useful to consider whether the mattress you're purchasing has any added features such as:

  • A cover that zips off for easy cleaning; 
  • Handles for turning; 
  • Hypoallergenic properties
  • Certifications like Greenguard, CertiPUR-US, or OEKO-TEX.
  • Temperature regulation – see our pick of mattress cooling pads for more. 

8. Buying a mattress in a box

Mattress in a box? Yes, it's a thing. Where once, we'd decide whether a mattress was right for us by spending just a few minutes on it in a shop (fully clothed, obviously), now you can have yours shipped out to you.

Why not? It makes sense. Why spend (or, we think, waste) your time trying mattresses in an overheated store when you can order a mattress in a box, have it delivered within days, then use the 100 day free trial that most of the best boxed mattress companies will give you to decide if it's the right mattress for you? And if it isn't, you can get either an exchange or, in many cases, a full refund with no hassle returns policies. 

Made from innovative materials that can be rolled (usually vacuum-packed) into a surprisingly small box, these mattresses can be easily hauled upstairs and unrolled, and regain their shape after just a few hours. 

Our top choice of all the mattresses in a box is the Casper and the Casper Hybrid. Also in our top 10 mattresses in a box are the Emma Original, Avocado mattress, Purple mattress, Tuft & Needle original mattress, Nectar mattress, and Leesa mattress. (We're clearly big fans of the concept!).

9. Will your mattress need turning?

Gone are the days when you had to periodically turn a mattress – undoing all that good work your mattress has done on your back in the process. Many newer mattresses don’t need turning, so check when you buy. If your new mattress does need turning, take note of whether it has handles or not, which will make maneuvering it much easier.

10. Can I use an electric blanket with a memory foam mattress?

Wondering whether you can use an electric blanket with your lovely new memory foam mattress? You've done all your mattress research, perhaps even read one of our mattress reviews. The issue is: you love your electric blanket, too, and might want to use it on cold nights, but you've heard memory foam and electric blankets are a no-go. True? 

The good news is that most memory foam mattress manufacturers say that their mattresses are fine to use with electric blankets. However, there are a few simple rules you can follow to ensure that you're not reducing the beneficial effects of your memory mattress.

Memory foam mattresses are so comfortable because the foam reacts with your body heat: this is how the molding process they're renowned for works. Moreover, some mattresses have complex layers of foam, so that you keep comfortable without overheating. One of the concerns about using an electric blanket with a memory foam mattress is that the mattress will become too warm and won't be as comfortable as a result. 

To make sure this doesn't happen, Nectar advise always 'prepping' your mattress by placing a sheet between it and the electric blanket. It's a good idea to do this anyway, for the sake of your own comfort and safety: sleeping on an electric blanket without a sheet as a barrier may lead to overheating and even injuries.

The other tip is to always warm up your electric blanket gradually, rather than cranking up the heat to the highest setting right away. You may well find that you're comfortable with a low setting, and the mattress is then much less likely to get too warm. 

Finally, always use a timer with your electric blanket. Experts recommend that, to keep your memory foam mattress in the best condition, they shouldn't be exposed to heat for more than half and hour at a time. Again, setting a timer is also essential for your safety. 

When to replace your mattress

The Better Sleep Council says that after seven-to-10 years your current mattress may not be offering adequate support. This will depend on the quality of the mattress in the first place and how much use it has had, but if your mattress is nearing that age it is time to check if you need a replacement.

If the mattress doesn't spring back to its original shape when you get off; has lumps and bumps; is dirty beyond cleaning; or is in any way uncomfortable it is time for a new one.
