Quick summary

The Saatva Classic is a luxury innerspring hybrid mattress, and our top recommendation for most people because it delivers effective full-body pressure relief, eases lower back pain, and doesn't retain heat. It comes in three firmness levels and two heights, so you can tailor it to your sleep position and body weight. The only other mattress in our top nine that offers a choice of firmness is the WinkBed at number eight: it isn't as luxurious as the Classic, but it's a better choice for anyone who weighs over 250lbs, thanks to the 'Plus' option.

The Saatva Classic isn't cheap: a queen size typically costs around $1,800. Still, that's less than many other luxury mattresses (close rival the Tempur Adapt is $2,199) and the quality is outstanding, with handcrafted detailing, and some natural and certified organic materials. You also get free white glove delivery and setup in the room of your choice. If your budget doesn't stretch that far, try the mid-range DreamCloud at number two instead – this hybrid innerspring isn't as luxe, but it's over $1,000 cheaper for a queen.

The Saatva Classic is an excellent choice for most sleepers – as long as you can afford the premium price tag. It sleeps cool, delivers effective full-body pressure relief, and eases lower back pain (for chronic back pain, I recommend the Saatva RX instead). The build quality and handcrafted finish is also the best my team has tested. If you're shopping for a mattress that delivers luxury hotel vibes at home, this is the one.

2. The best mattress in a box

A cheaper alternative to the Saatva Classic at number one

Specifications

Price: Mid-range
Type: Hybrid innerspring
Best for: Most sleepers; heavier bodies; couples with restless partners
Firmness: Medium firm
Sleep trial: 365 days
Warranty: Lifetime
Shipping: Free

Reasons to buy

+
Excellent value for money
+
Impressive comfort and support
+
Absorbs motion well

Reasons to avoid

-
Edge support could be better
-
May be too firm for lighter bodies
-
Not as luxurious as the Saatva Classic

Quick summary

We highly recommend the DreamCloud for anyone who loves the sound of the Saatva Classic at number one, but wants a cheaper alternative. This mid-range, hybrid innerspring mattress performed very well in our tests, delivering excellent back support and pressure relief for hundreds of dollars less than its higher-end hybrid rivals (we're looking at you: Saatva Classic, Helix Midnight Luxe and Winkbed). And while it doesn't have the premium features of those mattresses, we were impressed by its quality look and feel.

Yes, the DreamCloud isn't as luxurious as the Saatva Classic. And you don't get free white glove delivery and set-up: this mattress-in-a-box is delivered to your door, unless you pay extra. It's also one of the firmer mattresses we've tested (with no options to customize it, unlike the Saatva or Winkbed). But all our reviewers agreed it was very comfortable and supportive once they had adjusted to it – and we found that it was better at absorbing the motion of a restless partner than the Saatva, too.

The DreamCloud packs a real punch in the value-for-money stakes. The only reason it didn't take the number one spot here is that, side by side, the Saatva Classic is a better mattress: it's more luxurious, more supportive and more customizable for a wider range of people. But it also has a much higher price tag. If you're looking for a more affordable mattress but still want a quality feel and excellent support, I wholeheartedly recommend giving the DreamCloud a go. It comes with a one-year trial so you can make sure it's right.

3. The best affordable mattress

An excellent budget option from the makers of Nectar Mattress

Specifications

Price: From $199
Type: Memory foam
Best for: Back and stomach sleepers
Firmness: Medium-firm
Sleep trial: 180 nights
Warranty: 10 years
Shipping: Free

Reasons to buy

+
Reduces motion transfer
+
Stays cool during sleep
+
Supportive right to the edge
+
Great for front sleepers

Reasons to avoid

-
Much firmer than advertised
-
Little contouring
-
Not a luxury experience

Quick summary

The Siena Memory Foam is the highest-scoring budget mattress we've tested. It sits at the top of our affordable mattress rankings, delivering a better balance of comfort and support than the other budget option in our guide, the Linenspa at number nine (which is even cheaper, but not as good quality).

It isn't the best memory foam mattress out there: that award goes to the Nectar Memory Foam at number five. And we found it to be much firmer (rating it a 9 out of 10 on the firmness scale) than the medium-firm rating Siena gives, making it a great fit for the front-sleepers on our testing panel, but some side and back sleepers may need better pressure relief. Overall, though, it performs well for the price, with excellent edge support and surprisingly good temperature regulation for an all-foam bed – most people should sleep comfortably cool all night on the Siena. 

Expert verdict
Claire Davies
Expert verdict
Claire Davies

The Siena Memory Foam Mattress performs well for the lower price, achieving high test scores for edge support, temperature regulation and for how it reduces motion transferring from one side to the other. I rarely see affordable mattresses testing well in all of these key areas, so I recommend the Siena to people wanting a firmer mattress without paying over $500 for a king size. Skip it if you're a side sleeper though – for my team, it's too firm and doesn't have enough contouring for that position. There I'd recommend the Helix Midnight Luxe instead.

4. The best mattress for side sleepers

Sink-in softness and cradling comfort for shoulders, hips and knees

Specifications

Price: From $1,373
Type: Hybrid
Best for: Side sleepers
Firmness: Medium-firm
Sleep trial: 100 nights
Warranty: 15 years
Shipping: Free

Reasons to buy

+
Endorsed by chiropractors
+
Pressure relief for side sleepers 
+
Enhanced lumbar support 
+
Sturdy edge support

Reasons to avoid

-
Lacks handles for lifting 
-
Some off-gassing

Quick summary

The Helix Midnight Luxe is a specialist hybrid mattress designed for side sleepers, though we found it comfortable for back sleeping too. After testing it for over seven weeks it has become our top mattress for side sleepers because it delivers excellent pressure relief around the shoulders, hips and knees – major impact points when lying on your side. The mattress is 13.5" tall and comes in a medium feel (we rate it as a 6/10). The pillow top adds an immediate hit of softness, but you won't dip down into any subsequent layers as you would on a memory foam mattress.

At $1,780 for a queen on sale the Midnight Luxe is one of the more expensive options among our top nine, but as with the Saatva Classic the build quality is superb. The Midnight Luxe is 13.5" tall and comes in a medium feel (we rate it as a 6/10). It's a big upgrade on the original Midnight, our previous best choice for side sleepers, with a taller build, extra comfort layer and pillow top. The midnight Luxe is also more expensive at $1,780 for a queen compared to $999 for a queen Midnight.

Helix makes some of the best speciality mattresses in America – I rate the brand's Dusk Luxe for stomach sleepers, and the Midnight Luxe is my top pick for side sleepers. The Helix Midnight Luxe replaces the original Midnight (perfect if you want something more affordable – $999 for a queen at Helix), offering deeper pressure relief, extra comfort layers and a cooler feel. My lead tester's main criticism was purely cosmetic – no handles for moving, which does seem like a strange omission considering how heavy this hybrid is. If you sleep on your side and want the best for your position regardless of price, here it is.

The best memory foam mattress

A great choice if you like the hug of memory foam while you fall asleep

Specifications

Price: Mid-range
Type: Foam
Best for: Back sleepers; couples
Firmness: Medium firm
Sleep trial: 365 nights
Warranty: Forever
Shipping: Free

Reasons to buy

+
Competitively priced
+
Excellent motion isolation
+
Suits stomach and back sleepers

Reasons to avoid

-
Edge support could be better
-
No bounce

Quick summary

The Nectar Memory Foam is the highest-scoring foam-based mattress in our rankings, offering a better balance of comfort and support for the price than its nearest rivals, the Cocoon Chill (#7) and Siena (#3). You sink into this mattress slightly while you sleep: it contours to your body to provide cushioning support, giving you more of the classic memory foam 'hug' than the firmer Siena. (If you prefer a more traditional mattress feel, try a spring-based hybrid instead, like the DreamCloud.) 

Our reviewers felt well-supported in all sleeping positions – it's particularly good for side and back sleepers. We also found the Nectar to be cooler than most other memory foam mattresses we've tested. However, if you're a hot sleeper on a budget, consider the Cocoon Chill (if you like to sink into your mattress) or the DreamCloud (if you prefer to sleep on top of it).

Expert verdict
Claire Davies
Expert verdict
Claire Davies

I highly recommend the Nectar Memory Foam Mattress if you love the sink-in, contouring support of memory foam, but don't have thousands of dollars to spend. The Nectar isn't in the same league as pricer mattresses like the Saatva Classic, but you do get a good level of comfort and support for the money, and because it's medium firm it shouldn't take too long to adjust to after sleeping on a regular box spring. My team found it most comfortable for back sleeping, but I'm a side sleeper and I was comfortable on the Nectar Memory Foam too. Read more: Nectar Memory Foam mattress review

6. The best mattress for back pain

This specialist mattress for chronic back and joint pain is worth the investment for better sleep

Specifications

Price: From $1,795
Type: Hybrid
Best for: Sleepers with back and joint pain
Firmness: Medium-firm
Sleep trial: 365 nights
Warranty: Lifetime
Shipping: Free White Glove Delivery

Reasons to buy

+
Best-in-class back support
+
Relieves pressure points
+
Easy to get in/out of
+
Free mattress installation

Reasons to avoid

-
Too firm for side sleepers
-
600lb max weight capacity
-
$99 returns and exchange fee
-
Only one firmness option

Quick summary

The Saatva RX is a specialist hybrid innerspring mattress for back and joint pain, and we recommend it as the best option for people who need robust back support and pressure relief to ease pain that would otherwise disturb their sleep. While there are other mattresses here that reduce general aches and pains - such as the Saatva Classic and DreamCloud at number one and two - the Saatva RX is the only one with specific features designed with chronic pain in mind.

These center around Saatva's new Therapeutic Support Core, which enables the RX to adjust to your body when you move. In turn this reduces pressure points and boosts circulation – two crucial factors for reducing the amount of back and joint pain you feel when lying down. We found the Saatva RX doesn't retain much heat either. That's good, because heat build-up in a mattress can lead to restless sleep for some people, and tossing and turning in bed when you already have back or joint issues will make your pain worse.

Saatva RX Mattress: Expert verdict
Claire Davies
Saatva RX Mattress: Expert verdict
Claire Davies

Physical pain when lying down makes it harder for you to fall asleep and stay asleep. If the back or joint pain you're experiencing is a long-term situation, I recommend investing in the Saatva RX hybrid. It's expensive at $2,895 for a queen, but our testers with chronic back pain and conditions such as scoliosis slept better after just one night on the RX. The $99 returns fee is annoying when most other brands offer free returns, but otherwise the Saatva RX is an excellent specialist mattress. Alternatively, if you only have general aches and pains, save your money and buy the Saatva Classic at number one instead.

7. The best budget cooling mattress

A tried and tested affordable cooling mattress with the comforting hug of memory foam

Specifications

Price: From $399
Type: Memory foam
Best for: Cooling, back sleepers
Firmness: 6.5
Sleep trial: 100 nights
Warranty: 10 years
Shipping: Free

Reasons to buy

+
Great value cooling
+
Minimal motion transfer
+
Excellent pressure relief

Reasons to avoid

-
Weak edge support
-
Limited contouring
-
Not suitable for very hot sleepers

Quick summary

The Cocoon by Sealy Chill is a mid-range cooling mattress made with heat-wicking phase-change material. It isn't the best cooling mattress we've tested - that's the GhostBed Luxe, in the Also Tested section - but it's an impressive mattress and, crucially, is half the price of the GhostBed, making it more affordable for more people.

It feels very similar to the Nectar mattress at number five - both are memory foam and give you a 'hug' as you sink into them while you sleep. The Cocoon is marginally more expensive but a better choice for hot sleepers: our reviewers scored it highly for its impressive temperature regulation. It's also a good option for bed sharers, thanks to its enhanced motion isolation, but if you value edge support, upgrade to the Cocoon Chill Hybrid.

Expert verdict
Claire Davies
Expert verdict
Claire Davies

If you sleep hot and are craving the cradling comfort of a memory foam mattress, the Cocoon by Sealy Chill is your best option thanks to a combination of contouring foam coupled with a heat- and sweat-wicking cover. Proper cooling mattresses normally cost thousands of dollars, but the Cocoon by Sealy Chill Memory Foam bucks that trend by costing just $699 for a queen (and you get $179 worth of free cooling sheets). Avoid it if you need a breathable mattress with strong edge support though – I'd recommend the Siena Memory Foam Mattress instead (it's nearly half the price but a lot firmer).

8. The best firm mattress

A firm mattress with head-to-toe support for all body types

Specifications

Price: From $849
Type: Hybrid
Best for: Stomach sleepers / heavier people
Firmness options: Soft, luxury firm, firm, plus
Sleep trial: 120 nights
Warranty: Lifetime
Shipping: Free

Reasons to buy

+
Full body pressure relief
+
Edge-to-edge support
+
Suits all sleep positions

Reasons to avoid

-
Retains some heat
-
Less luxurious finish

Quick summary

The WinkBed Mattress is our favorite firm mattress for back and stomach sleepers, with the three-step back relief system providing head-to-toe support while maintaining ample pressure relief. Available in four firmness levels, including Plus for those weighing over 250lbs, the WinkBed can suit a range of sleep styles.

While it's similarly priced to the Saatva Classic (#1), we discovered during testing that The WinkBed lacks the temperature regulation and luxury finish of our the Saatva.

Expert verdict
Claire Davies
Expert verdict
Claire Davies

Because firm mattresses offer the highest levels of support, the comfort layers need to be well-balanced otherwise you'll feel like you're sleeping on a plank of wood. The WinkBed is one of the best my team has tested for combining firm support with the right level of contouring comfort. There is a Plus option if you have a heavier body, otherwise The WinkBed Firm is my top choice for anyone seeking a harder mattress with ample pressure relief. With its three-step back support system, The WinkBed is also a good choice for back pain if your budget doesn't stretch to the Saatva RX (number six).

9. The best mattress under $300 for a queen

A budget hybrid mattress that can't be beaten on price

Specifications

Price: From $129.99
Type: Hybrid
Best for: kids and guest rooms
Firmness options: Medium-firm
Sleep trial: N/A
Warranty: 10 years
Shipping: Free

Reasons to buy

+
Comes in three heights
+
Affordable for a hybrid bed
+
Best for kids and guest rooms

Reasons to avoid

-
Lacks support for heavier people
-
Takes a while to expand

Quick summary

The Linenspa Memory Foam Hybrid Mattress is a hybrid bed catering to those on an ultra-tight budget. This inexpensive mattress comes in three height options, with the shortest model priced at under $300 for a queen. We know from testing that this isn't the most durable mattress by any stretch, but it's a suitable choice for guest rooms and for older children who will outgrow a mattress in just a few short years. 

The combination of open coils and responsive foam also means it provides plenty of support and comfort to lightweight stomach sleepers. 

Expert verdict
Claire Davies
Expert verdict
Claire Davies

If you're shopping for a cheap mattress on Amazon, I only recommend a handful of brands. Linenspa is one of them and I rate this particular model – to a degree. The Linenspa Memory Foam Hybrid 8" isn't as supportive or breathable as every other mattress on this list, but it is a lot cheaper at $249 for a queen (a rock bottom price for a hybrid mattress). So if the main thing your new mattress needs to have is a cheap price, and you want a hybrid mattress for a child or teen from a well-known affordable bed brand, the Linenspa Memory Foam Hybrid 8" is worth trying.

How we test mattresses

The Tom's Guide mattress review process is editorially independent and not influenced by third parties. We research and test the latest mattresses in all key areas – pressure relief, temperature regulation, support and comfort, edge support and durability – to create unbiased product recommendations. Only the vest best make it into this guide.

Our expert mattress testers sleep on each mattress for at least three weeks: that’s roughly how long it takes for your body to get used to a new mattress.

Mattress firmness is subjective though, so we don’t just take our lead reviewer’s rating into account. We also ask a trusted and experienced testing panel, made up of people with different sleep needs and body types, to rate each mattress using a specific set of performance criteria.

Image shows one of our mattress testers sleeping on a hybrid mattress on her side and the other tester sleeping on the same mattress but on her stomach

(Image credit: Future)

We have side sleepers, back sleepers and stomach sleepers, with lighter, average and heavier bodies, to ensure we get a well-rounded view of what each mattress feels like.

We also run a series of in-house tests using weights to gain an objective view of how each mattress performs compared to other models. After analyzing our test data and conducting extensive user review research, we rate each mattress out of 5. We then compare how the mattress performs versus other mattresses we’ve reviewed. This enables us to clearly see which mattresses are best for different sleepers.  

Our testing process, which you can read about in our mattress methodology, includes the following processes:

  • We test each mattress across all key areas: support, comfort, pressure relief, motion isolation, temperature regulation and edge support.
  • We analyze user reviews to get an understanding of what real customers think of each mattress, and a feel for any recurring themes which we explore further during testing.
  • We fact-check every comfort and support claim made by a mattress brand.

How to choose the best mattress for you

A good night's sleep helps you to feel healthy, well-rested and productive, and your mattress plays a key role in that. If you’re shopping for a new mattress but don’t know where to start, that's where we come in: our guide to this year's best mattresses contains our top choices for different sleepers and budgets so you can easily find the right one for you.

There are seven factors to consider when choosing a mattress:

  • Your sleep position
  • Your weight
  • Your health
  • Mattress size
  • Firmness

Some people don’t need to consider all of those factors – if you’re young, fit and healthy, with zero sleep issues, a standard mattress in a box should suit you fine. But if good sleep is proving elusive, the right mattress can get you back on track in most instances.

^ Back to the top

Your sleeping position

The are four major sleep positions: side, stomach, back and combination (where you switch between two or more sleeping positions throughout the night). Learning how to choose a mattress for your sleep position will help you quickly narrow in on the right type of bed for your sleep style.

Here’s a quick overview of which mattress types suit different sleep positions:

  • Side sleepers – soft to medium contouring memory foam mattresses
  • Back sleepers – medium-firm hybrid mattresses or firmer memory foam mattresses
  • Stomach sleepers – medium hybrid or memory foam mattresses if you have a lighter weight body; medium-firm to firm if you weigh more
  • Combination sleepers – a medium-firm hybrid or memory foam mattress that stops most motion from being transferred from one side of the bed to the other.

Your weight

Every mattress is designed with support and comfort layers, and the extent to which you feel the benefit of those layers depends on your body weight. We cover this in more detail below, but essentially people with a lighter body weight (the mattress industry classes this as 150lbs and under) usually sleep better on a softer mattress with a focus on comfort. 

People of an average to heavier build (a wide range of body weights from 155lbs to 245lbs), usually sleep comfortably on medium to medium-firm mattresses. If you weigh over 250lbs and share with someone of an equal or higher weight, you’ll experience better full body support on a firm mattress.

^ Back to the top

Your health

Some physical health conditions, such as pain and overheating, affect how easily you fall asleep, the quality of your sleep and the duration. Research tells us that mental health conditions such as stress, depression and anxiety also affect sleep, usually manifesting as insomnia.

A good mattress can help you feel cooler and more comfortable, but it isn’t a cure for insomnia or stress. However a mattress that suits your body type coupled with good sleep hygiene and support from your doctor can improve your chances of sleeping better.

Our specialist guide to the best mattress for back pain, with advice from licensed chiropractors, explains how to choose a mattress if back, hip and joint pain are affecting your sleep. If overheating is the issue, our guide to this year’s best cooling mattresses for hot sleepers runs you through the different options available and how to choose.

Mattress size

The most common mattress sizes in the US are (dimensions listed in inches):

  • Twin (38 x 75”)
  • Twin XL (38 x 80”)
  • Full (54 x 75”)
  • Queen (60 x 80”)
  • King (76 x 80”)
  • Cal king (72 x 84”)
  • Split Cal king (72 x 84” split)

Our complete guide to mattress sizes in the US explains how to choose the right size mattress for your body, sleeping position, the person you bedshare with (if you share), and other considerations such as the size of your bedroom. 

The most popular mattress size in America is a queen, and from testing we’ve found that this is a great choice for couples who enjoy sleeping closer together. Twin size mattresses, in comparison, are the ideal choice for children, while Twin XLs suit teens as well as adults sleeping solo in a small apartment.

Mattress firmness

Mattress firmness describes how hard or soft a bed feels, and the mattress industry measures it on a scale of 1-10. 1 = marshmallow soft and 10 = hard as a plank of wood. Comfort is subjective, so we have one lead tester for every review as well as a wider testing panel made up of people with different sleep preferences and weights.

So how firm should a mattress be? Here’s a full breakdown of the different firmness ratings, what they feel like and who they will and won’t suit:

Back sleepers often benefit from a medium-firm mattress. This provides neutral spine alignment while supporting the hips and shoulders. If a mattress is too soft, back sleepers may find their spine forming an uncomfortable 'U' shape, creating strain. Too firm and the natural 'S' curve of your spine won't be supported. 

Side sleepers need good pressure relief on their shoulders, knees and hips. A medium to medium-soft mattress is usually a good choice. If it's too soft, the spine won't align properly with the shoulders and hips. Memory foam is often the best mattress choice for side sleepers due to its above-average contouring.

Front sleepers fare better with a firmer mattress. This lifts the hips up so that they're in alignment with the spine, and prevents the spine from forming a 'U' shape. If it's too firm it'll be uncomfortable - particularly for women - and won't allow the spine to curve naturally. Too soft and it can feel almost suffocating. Innerspring and hybrid mattresses can be a better choice than foam for front sleepers.

Combination sleepers should choose according to their dominant sleep position (the position you normally fall asleep in). If you don't have one, a medium firm mattress will dish out the best support and comfort across most positions.

Mattress buying advice: Ask our experts

It's natural to have questions when you're shopping for a mattress, and our expert mattress testers and certified sleep science coaches have over extensive experience with traditional and boxed mattresses. Here we answer frequently asked questions about the different types of mattress, how to choose the right one for you, plus when is the best time to buy and where.

When is the best time to buy a mattress?

The best time to buy a new mattress is during five major sale events dotted throughout the year, as well as the 4th of July mattress sales. But when it comes to super-savings, one sale trumps all others. 

Presidents’ Day mattress sales can bring impressive discounts, with major retailers driving prices down in a bid to boost sales during a quiet time of year. Presidents’ Day falls mid-to late February and is a great time to buy if you missed out on Black Friday. 

The Memorial Day mattress sales, which land at the end of May, is the last major sale event before summer, making it an excellent time to pick up a discounted cooling mattress. However, Memorial Day discounts aren’t quite as impressive as Presidents’ Day or Labor Day.

Think of the Labor Day mattress sales as a warm-up event to Black Friday. Sales typically range from 15% to 60% off and , if previous Labor Day sales are anything to go by, this is when we could see the Saatva Classic drop to its lowest price of the year. 

The Black Friday mattress deals and sales in late November bring with them the biggest discounts and cheapest prices of the year. All of our top rated mattress brands offer record-breaking discounts on their best-selling beds during this time, with savings continuing through to Cyber Monday.

How much should you pay for a good mattress?

At Tom’s guide, we’ll always recommend paying what you can afford for a good quality mattress. While you can pick up a cheap mattress for less than $500 for a king size, certain concessions will need to be made in order to keep prices low, such as durability and overall performance.

For example, the Zinus Green Tea Memory Foam Mattress is a decent choice for anyone looking for a budget-friendly option with reliable pressure relief, but temperature regulation is a little unreliable. For context, regular sales means that a twin is $249 (was $399), a queen is $399 (was $599) and a king is $449 (was $699).

However, increasing your budget to the mid-range price category gets you an increase in quality across construction, materials, support and comfort, making it the sweet spot for quality versus value for money. Here we recommend The DreamCloud at $665 for a queen and the Cocoon by Sealy Chill Cooling Memory Foam Mattress at $699 for a queen with $179 of free bedding.

The premium mattress category is where you’ll find the Saatva Classic, our top-rated mattress for all sleepers with the budget. A good Saatva discount usually takes the price of a twin size Classic down to $1,095 (usually $1,395), a queen down to $1,695 (usually $1,195) and a king down to $2,195 (was $2,495).

What are the different types of mattress?

Choosing the best mattress for you starts with identifying the type of mattress that suits your sleep style. There are four main types of mattresses: memory foam, hybrid, innerspring, and latex. Each type comes with its own broad characteristics, so less dive into the pros and cons.

Memory foam mattresses

Memory foam mattresses consist of layers of dense, cushioned foam. Known for their body hugging properties, the best memory foam mattresses contour to your shape to relieve pressure and reduce motion transfer. 

Dense, cushioned memory foam can hold onto heat, meaning they aren’t ideal for hot sleepers unless they use materials designed to dissipate heat quickly. Memory foam mattresses are typically cheaper than hybrid mattresses, with the average memory foam mattress costing $650 to $1,200 for a queen. Nectar and Tempur-Pedic are two of the most popular memory foam brands.

Hybrid mattresses

Hybrid mattresses feature a core of supportive springs combined with layers of comfort materials (often memory foam, but sometimes latex or wool). Due to these springs, hybrids are breathable and bouncier than all-foam beds. 

This bounce makes it easier to move around, but potentially disruptive for bed sharers. Hybrid mattresses can be expensive, with a queen size hybrid typically costing between $800 and $1,500. The brand currently topping our best hybrid mattress of the year guide is Saatva, but DreamCloud and Helix are high-quality alternatives.

Innerspring mattresses

Innerspring mattresses are traditional coil-based mattresses. With plenty of room for air to circulate, innerspring mattresses are breathable, and the buoyant feel means you sleep on top of the mattress, rather than sinking in. 

This makes innerspring beds a good choice for back and stomach sleepers, but they lack the contouring comfort of foam-based options. Innerspring mattresses are often budget-friendly choices, and while they’re less popular nowadays, brands such as Mattress Firm and Sealy still offer quality innersprings.

Latex mattresses

Latex mattresses are the most common type of organic mattress. Instead of synthetic foams, these beds use foams made of natural latex, a bouncy and breathable material that offers plenty of support and temperature regulation.

Latex doesn’t have the same sink-in feel of softer foams, but thanks to its durability, it’s a good investment choice. However, latex beds are premium buys, often costing from $1,000 to several thousand dollars for a queen. The best organic mattresses come from brands like Avocado, Awara, and Saatva.

How often should you replace your mattress?

How often you should replace your mattress depends on a number of factors, including construction and design. For instance, mattresses tend to have a base layer of dense foam or springs, which acts as the support core. So the thicker the support core of the mattress, the longer it should last.

Rotating your mattress regularly and covering it with a good mattress protector can prolong its life. Here’s how long a mattress should last based on design and material:

Memory foam mattresses last up to 10 years on average.Thanks to their all-foam construction, these mattresses aren’t susceptible to the noisy creaking of worn-out springs and have less components to deteriorate than innerspring or hybrid mattresses.However, memory foam mattresses are still prone to sagging and their temperature control and edge support tend to decline over time.To avoid premature sagging, we recommend rotating your memory foam mattresses every few weeks.

Hybrid mattresses contain coils or springs, which do have a tendency to deteriorate quickly, causing premature sagging and noisy creaking. Other components such as memory foam comfort layers and pillow tops can also start to sag and lose performance over time, so hybrid mattresses should be replaced every eight to 10 years. Like foam beds, hybrid mattresses should be rotated every few weeks. 

Innerspring mattresses have the lowest lifespan, with a life expectancy of five to seven years.This is due to their design being made up entirely of springs or coils, which wear out rapidly. To prolong the life of an innerspring mattress, flip it over every few months. 

Latex mattresses have the highest lifespan, lasting 15 to 20 years. This is due to latex being naturally dense and durable and, as a result, more expensive. However, despite their premium price tags, latex mattresses are a good investment if you’re looking for a mattress that won’t need to be replaced often. Be aware, though, that some latex mattresses are hybrids containing springs or coils, which wear out quickly and can lower the life expectancy.

What mattress should you buy for your weight?

A person weighing 150lbs and a person weighing 250lbs can test the same mattress and find it has a completely different feel. Body weight affects both the comfort and support of the bed, so when choosing a mattress, it’s important to consider which mattress is right for your body type.

People weighing 150lbs and under should opt for a softer or medium feel mattress. As there’s less pressure applied to the mattress, a softer bed will provide the yield and contouring needed for both comfort and support. Memory foam mattresses are a good choice, as they provide ample cushioning.

People weighing 155lbs to 245lbs should choose a medium-firm mattresss. There are plenty of options in this category, so make sure to consider your sleep style alongside your build. For example, a side sleeper with a lightweight frame should look for a softer mattress, while a heavier back sleeper should opt for something firmer.

People weighing over 250lbs should choose a firm mattress, as these provide relief where your body presses against the mattress without the quicksand sinking feel of softer mattresses. The best mattresses for heavy people are specialist beds, typically hybrids, with a strong supportive core that offers even weight distribution.
