Looking for the best mattress 2020? We totally get it. Sleep is so important for our health and wellbeing which is something often determined by the mattress we reside to at the end of each day.

Yet while finding the best mattress used to be as simple as a trip to the local mattress store to spend a few hours assuming your favorite sleep position on their inventory, these days there are also dozens of so-called Internet mattresses to consider, too; brands like Casper and Purple that will ship a mattress straight to your door (often neatly wrapped up in a box). In fact, by one estimate from CNBC, there are nearly 200 online mattress companies that have cropped up in the last 10 years.

To help you choose a mattress, we took it upon ourselves to try out, test and research the best mattresses on the market this year. It was quite an enjoyable experience for us (zzzz), and all in an effort to help make your decision easier. You'll find our top buys in this guide – keep scrolling to the end of the page to checkout all the mattress reviews for yourself.

1. Saatva Hybrid Mattress

Best mattress overall

Sizes: Twin, twin XL, full, queen, king, Cal king
Depth: 11.5"
Type: Hybrid
Firmness: Medium
Reasons to buy
+Comes in three firmness levels+Hybrid combines memory foam and coils+Organic cotton cover, CertiPUR-US foam+Stays cooler than an all-foam mattress
Reasons to avoid
-On the more expensive side

This mattress nabbed our number one spot for a whole bunch of reasons, but to put it simply: this one's got it all. The Saatva mattress is a hybrid, which means it combines both memory foam and innerspring technologies, so you get the best of both mattress worlds. Plus, it's made from top-quality materials like CertiPUR-US foam and organic cotton. and the price point is affordable (though not cheap), especially for a mattress of this quality. 

What is the Saatva mattress like to sleep on? 
Our best comparison is a high-end hotel bed. It's got a cozy, sink-in factor thanks to the pillow top, but the innerspring layer below adds plenty of support for spinal alignment and pressure-point elimination. The mattress comes in three firmness levels, Plush Soft, Luxury Firm, and Firm, with most customers finding the medium-rated Luxury Firm version to be ideal. We agree, and think it's a happy medium that'll appease stomach, back, and side sleepers. 

Special features
One reason why we love a hybrid mattress is that it's able to solve some of the cons that come with owning a traditional memory foam mattress. Among the things this hybrid does better than standard memory foam: edge support and air flow. If you've ever sat down on the side of your memory foam bed to put on your shoes, then you'll appreciate that the Saatva mattress offers excellent perimeter edge support thanks to dual-reinforced edges. And coil construction allows air flow that's hard to match from an all-foam mattress.

The top of the mattress is a pillowtop made from CertiPUR-US foam, enveloped in an organic cotton cover. The middle of the mattress features the brand's Spinal Zone active wire support system, designed to maintain spinal alignment. The coils are made from recycled steel. 

Shipping and warranty 
The Saatva mattress comes with free delivery and in-home setup, plus optional free removal of your old mattress. Plus, you'll get a 120-night in-home sleep trial.

Best mattress 2020: Emma mattress

2. Emma Original Mattress

Best mattress for back sleepers

Size: Twin - Cal king
Depth: 10"
Type: Comfort foam/memory foam
Firmness: 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 comfortable, supportive, and incredibly affordable. (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 back sleepers and those who are looking to eliminate motion transfer.

What is the Emma like to sleep on?
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.

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. 

Shipping and warranty
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

3. The Casper Mattress

The best mattress for firmness

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!

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. 

Shipping and warranty
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 - avocado mattress

4. Avocado Green mattress

Most sustainable mattress

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.

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.  

Shipping and warranty
A 100-night trial, and a 25-year guarantee, one of the longest of any we reviewed.

best high tech mattress - purple mattress

5. Purple Mattress

Best innovative mattress

Size: Twin - Cal king
Depth: 10"
Type: Hyper-Elastic Polymer/ foam
Firmness: Medium
Reasons to buy
+Excellent 'give' for side sleepers+Proprietary Hyper-Elastic Polymer+Soft but supportive+Good for combo sleepers
Reasons to avoid
-May be too firm for strict side or stomach sleepers

If you thought finding the right mattress wasn't rocket science, think again. The Purple mattress is made from a proprietary Hyper-Elastic Polymer developed by two brothers (one of whom is a rocket scientist) over years of testing.

Who will the Purple mattress suit?
This is an excellent pick all-around, but it especially suits combo sleepers who spend time on their back, stomach and side throughout the night.

What is the Purple mattress like to sleep on?
In a nutshell, the grid construction of this mattress is designed to support your body as you move during sleep, no matter what position you end up in. It is responsive and molds to your body, while also offering excellent levels of support. Designed to accommodate all types of sleeping styles – back, stomach or side – there is no ‘wrong’ way to catch some Zzzzzs on the Purple mattress.

Review-wise, many would rate this mattress on the firmer side, but most agree this mattress falls at a six or seven out of 10 on the firmness scale. It's also hypoallergenic, and features open-air channels that help neutralize body heat throughout the night.

Special features
There's nothing else like it; you won't find Purple's Hyper-Elastic Polymer anywhere else.

From the top: A 2" layer of Hyper-Elastic Polymer material laid in a grid (also called "The Purple Grid.). Next is a 3.5" layer of CertiPUR-US certified polyurethane foam, and the base layer is 4" of slightly denser polyurethane foam. The cover is a soft, breathable combination of viscose, polyester, and Lycra.

Shipping and warranty
Free delivery, 100-day free trial, plus a 10-year guarantee and hassle-free returns. We've also seen free sheets with the purchase of a mattress offered on the site periodically.

Size: Twin - Cal king
Depth: 10"
Type: Foam
Firmness: Medium
Reasons to buy

Say hello to your happy medium: the Tuft & Needle original mattress is a not-too-hard, not-too-soft foam mattress that's just right for all sleeping positions. According to the company, 95 percent of customers keep and love their Tuft & Needle original mattress. It also falls in the middle of the road when it comes to pricing.

Who will the Tuft & Needle original mattress suit? 
This is the ideal mattress for all different types of sleepers. Side-sleepers, those who suffer with Goldilock’s Syndrome (not too soft, nor too hard syndrome), and anyone who is simply looking for luxury and comfort every night. 

What is the Tuft & Needle original mattress like to sleep on? 
The Tuft & Needle original mattress is equal parts support and softness. It's made from T&N Adaptive® foam, which is engineered based on customer feedback. While the mattress is made from foam, it's not memory foam; instead, it's built with a denser bottom layer of open-cell foam, and a soft, breathable top layer. This makes it easy to move around on, which is why we're calling this one a great choice for fussy sleepers, or people who find themselves tossing and turning often at night.

A layer of cooling gel also makes it a top pick for those who tend to sweat at night.

Given its low-VOC and PBDE-free status, this mattress is an excellent choice for children (our team has purchased it for their own kids), and those with chemical sensitivities.

The bottom of the mattress is a 7" layer of open cell support foam which creates a breathable base. On top? A 3" a layer of softer T&N adaptive foam, which is infused with heat-wicking graphite and cooling gel beads, and designed to provide flexible support to the spine.

What's the Nectar Mattress like to sleep on?

It features a decent layer of proper memory foam which is nicely aerated, and then pressure relieving foam that contours to your body shape. Finally the seven-zone base foam provides additional contoured support plus depth.

8. Leesa Original Mattress

Best mattress for side sleepers

Size: Twin - Cal king
Depth: 10"
Type: Comfort foam/ memory foam
Firmness: Medium
Reasons to buy
+Medium firmness+Good breathability for sweaty sleepers+Good motion transfer+B-Corp certified company
Reasons to avoid
-Sponge-clean only

This luxuriously thick memory foam mattress will soon have you sleeping like a baby. It's great for all sleep positions, but we especially like it for side sleepers. Plus, thanks to its top cooling layer, it's a memory foam option that even hot sleepers will love.

Who will the Leesa mattress suit?
This Leesa original mattress is a good buy for risk-adverse shoppers looking for a safe bet that they’ll sleep soundly. It's rated a 5-7 on the firmness scale (with 10 being the most firm) meaning it's supportive, but still soft enough to sink into. In other words, a great choice for side sleepers. 

What is the Leesa mattress like to sleep on?
Initially quite firm, this mattress softens as it warms to your body temperature. That's not to say you will sleep warm. On the contrary, its carefully considered foam layers are specifically engineered to regulate temperature and prevent overheating. The Leesa performs well in the motion transfer category, and you can expect medium firmness, which is especially ideal for side-sleepers. The majority of (the many) online reviews rate it between four and five stars (five being the top spot), which is always reassuring. 

Special features
As a certified B-corp., we love Leesa’s ethical values, which include donating one mattress to a child in need for every 10 sold. It's also made in the USA. On a more materialistic note, the grey-striped cover is pretty cute.

Three foam layers – a 2" thick Avena foam, which is a latex-like comfort foam, a 2" thick memory foam for weightlessness, and a 6" thick base foam for overall support. 

Shipping and warranty
A 100-night, no-risk sleep trial, free delivery and returns and a 10-year limited warranty.

9. Awara Mattress

Best latex mattress: Organic latex and innerspring coils create a cool, natural night's sleep

Size: Twin - Cal. king
Depth: 13"
Type: Latex hybrid
Firmness: Medium
Reasons to buy
+Made from all-natural Sri Lanka latex+Great airflow+Certified organic+Non-toxic
Reasons to avoid

Looking for an all-natural alternative to memory foam? A latex mattress is your best bet. We love the Awara mattress for its purity and comfort. 

Who will the Awara mattress suit?
If you like idea of memory foam but prefer a green alternative, the Awara mattress is a top choice.  It's all natural, organic and non-toxic. The mattress is made from Dunlop latex, organic wool, organic cotton, and steel (for the coils), and is made without chemical flame retardants, formaldehyde, and polyurethane-based foams.

This mattress is also breathable, which is ideal for hot sleepers, thanks to a coil spring base that promotes airflow. 

What is the Awara mattress like to sleep on?
The Awara mattress is a medium firmness mattress that has a little more give than some of the other latex-hybrids on the market thanks to its 4" layer of latex at the top (the thickest of any latex hybrid on the market). This makes it an excellent pick for side and stomach sleepers, as well as a good choice for lighter-weight back sleepers (we'd say under 200 lbs).

Since it's a hybrid, the motion transfer won't be as good as a memory foam mattress, but you'll make up for it with extra bounce and edge support. 

A certified-organic cotton cover is filled with a naturally fire-retardant wool comfort layer, a pressure-relief latex layer, and a support layer made of individually-wrapped steel coils.

Shipping and warranty
The Awara mattress comes with free shipping, a 365-night sleep trial, and a lifetime warranty.

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 to be turned?

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.

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.
