I’ve been testing mattresses for over five years and have learned that comfort is subjective, so the best mattress for you will be different to what feels good to me. And that’s ok. Choosing a mattress that suits your body and sleep style is a great investment because the comfier you are in bed, the better you’ll sleep and the healthier you’ll feel afterwards.

For over half a decade my team of sleep experts and I have spent thousands of hours researching, sleeping on and testing all the latest mattresses (traditional and boxed). I know from analysing all that test data, and from reading user reviews, that the best mattresses relieve pressure points across your body, keep your spine aligned to prevent back pain, and keep you at a comfy temperature for sleeping. 

I’ve ranked the top-performing options for every budget in this guide, and several of them are now reduced in price thanks to this year’s Black Friday mattress deals. As a Certified Sleep Science Coach I’m also sharing all my knowledge of how to choose the best mattress for you, with my expert tips on what to look for and what to avoid located further down this guide.

Doesn't look luxurious

Quick summary

We loved the Simba Hybrid Ultra Mattress so much we awarded it top marks — a full five stars. It's a true medium-firm bed, with a squishy and pressure relieving surface combined with head-to-toe support.

The Hybrid Ultra is the tallest, most luxurious mattress in the Simba line-up, featuring nine internal layers and the very best of Simba's sleep technology. It's also the most expensive bed in the range (and this guide), with prices starting at £1,899. That's a lot of money for a mattress but this is a bed we struggled to find fault with. It's breathable and cool for hot sleepers, supportive from edge-to-edge, and despite a bouncy finish, bed sharers can sleep soundly without disturbing their partner.

Simba is one of the best mattress brands in the UK and the Hybrid Ultra hits that sweet spot between performance and price. You get a lot of mattress for your money here, including a cooler sleep surface and excellent pressure relief. It has a good bit of bounce to it, while still isolating motion transfer from your partner for an undisturbed night’s sleep. The Simba Hybrid Ultra isn’t cheap at £2,043 for a double this Black Friday, but I think it’s well-worth the money. For a cheaper alternative, I recommend the original Simba Hybrid (from £449) – it isn’t as polished and the edge support is weaker, but it’s a good affordable hybrid for couples and teens.

2. The best affordable mattress

A classic memory foam cradle for back and stomach sleepers

Specifications

Price: From £349 on sale (£833 RRP)
Type: Memory foam
Best for: Back and front sleepers
Firmness (1-10): 6.5
Sleep trial: 365 nights
Guarantee: Lifetime
Shipping: Free named day

Reasons to buy

+
Contouring pressure relief
+
Versatile feel
+
Impressive motion isolation

Reasons to avoid

-
Weaker edges
-
Long break in for side sleepers

Quick summary

Offering excellent value for money, the Nectar Memory Foam Mattress is a well-priced bed from one of our favourite sleep brands. The medium-firm feel is comfortable for back and stomach sleepers, but this is a good all-rounder with enough pressure relief to suit most side sleepers.

The Nectar's closest rival is the Zoma (#2), but the Nectar delivers more of a classic foam feel. Even though it isn't a bed you sink into, it cradles the body while distributing weight across the mattress. And the lack of sink means it avoids some of the pitfalls of affordable memory foam beds — like poor temperature regulation. Our testers found the Nectar breathable and although it's not as cool as the Levitex at #10, it doesn't overheat, either.

Claire Davies
Claire Davies

Nectar was one of the first mattresses I ever tested, and I’ve since recommended it to dozens of sleepers searching for a firmer feeling, affordable memory foam mattress in a box. It also regulates temperature well for an all-foam mattress, so hot sleepers (like me) should feel comfortable on it. I think the Nectar Memory Foam is excellent value for money at £499 this Black Friday and a consistently top ranking mattress in our guide, but an even cheaper option is the Emma Original (see our Also Tested section) at £399 for a double. I prefer the Emma Original for side sleeping (read my Emma Original Mattress review to learn why), but the Nectar is the better all-rounder and it has a better build quality.

3. Best luxury mattress

Latex luxury with pillow top cushioning

Specifications

Price: From £1,099 RRP
Type: Latex hybrid
Best for: Side sleepers
Firmness (1-10): 7
Sleep trial: 100 nights
Guarantee: 5 years
Shipping: Free

Reasons to buy

+

-
Limited versatility

Quick summary

We were blown away by the Relyon Bridgwater Dunlopillo Latex Mattress, awarding it five stars after a thorough testing period. It feels sumptuous, with a pillow top layer that adds an immediate hit of cushioning, plus a finish that wouldn't look out of place in a luxury hotel room.

The Relyon is handcrafted to order and it took five weeks for our model to arrive. But it was worth every moment of the wait. The tufted pillow top delivers sink in softness that's ideal for side sleepers, and you can feel the pressure relief all across the body. Although it's less comfortable for back and side sleepers, which is why we awarded number one to the Simba Hybrid Ultra.

Claire Davies
Claire Davies

 I’ve just finished sleeping on the 12-layer Simba Earth Apex so I know the difference a great luxury mattress can make to your sleep. My lead tester for the Reylon Bridgwater Dunlopillo Latex Mattress recommends it as a comfortable hotel mattress at home for most sleepers, but she did report that the pillow-top isn’t ideal for people who want a firmer feeling mattress. If that’s you, I recommend the Otty Extra Firm Hybrid Mattress (#8) instead. It’s nearly £690 cheaper for a double in the Black Friday sales too and the warranty is twice as long (10 years versus five at Reylon). Otherwise, if you have the budget and you love sink-in soft pillow-top mattresses with a luxury look, the Relyon Bridgwater has a lot to offer including full body pressure relief and excellent cooling (thanks to latex).

4. The best mattress for side sleepers

Full-body pressure relief that cradles the shoulders and hips

Specifications

Price: From £1,389 RRP
Type: Hybrid with AirGrid technology
Best for: Side sleepers
Firmness (1-10): 3.5
Sleep trial: 200 nights
Guarantee: 10 years
Shipping: Free

Reasons to buy

+
A floating "weightless" feel
+
Deep pressure relief
+
Sleeps cool

Reasons to avoid

-
Weak edges
-
Too soft for stomach sleepers

Quick summary

The Emma Elite Mattress takes a different approach to comfort, as this hybrid bed features springs, foams, and the Emma AirGrid technology. It's this hyper-elastic polymer layer that has earner the Emma Elite our side sleeper recommendation, thanks to an adaptive comfort that moulds to your body to relieve pressure from head-to-toe.

Our review panel loved the feel of the Emma Elite's AirGrid, as it offers full-body support without a firm feel. Instead, it's as if you're "weightless", somehow lying on top of the mattress while it hugs you at the same time. It's not exactly the foam feel of the Nectar (#4), but it's not a hybrid bounce like the Simba Earth Escape (#11) either. But it is highly breathable, and hot sleepers should find themselves comfortably cool on the Emma Elite. Although stomach sleepers and those with a heavier build should consider a firmer support, such as the REM-Fit 500 Ortho (#7).

Claire Davies
Claire Davies

I’ve slept on every Emma UK mattress and to me this feels the softest. That means I wouldn’t recommend it to heavy (over 250lbs) back and stomach sleepers, but side sleepers of most shapes and sizes will love the Emma Elite (plus size side sleepers may need to add a firm topper). As a hybrid mattress it has a bouncier feel than the Emma Original, but it’s also much more expensive at £1,024 for a double in the Emma Black Friday sale compared to £399 for the Emma Original. While the Emma Elite isn’t a proper cooling mattress, it quickly wicks away excess body heat (it’s designed with Emma’s AirGrid tech) and sweat. I also rate the hyper-elastic polymer grid and how it flexes with your every move to contour your body, relieving any pressure points. Side sleepers with hip pain will love it.

5. The best hotel-style mattress

An upper mid-range hybrid with a luxury hotel feel

Specifications

Price: From £375 on sale (£966 RRP)
Type: Hybrid
Best for: Side sleepers
Firmness (1-10): 6.5
Sleep trial: 365 nights
Guarantee: Lifetime
Shipping: Free named day

Reasons to buy

+
Luxury finish
+
Soothing pressure relief
+
Consistent edge support

Reasons to avoid

-
Softer support for a hybrid
-
Might need to be broken in

Quick summary

For hotel-like luxury that doesn't break the bank, look to the DreamCloud Hybrid. This upper mid-range mattress pairs thick body-hugging foams with a supportive base, all wrapped in a luxurious looking package.

If you like the sound of the Relyon Bridgwater Dunlopillo Latex Mattress (#3) but it's out of your budget, the DreamCloud is an excellent alternative. For a hybrid. it has an unexpected body-hugging feel, with the top foam layers embracing the body in a way reminiscent of the best memory foam mattresses, such as the Nectar (#4). We recommend it for side sleepers who want cushioned pressure relief and the bouncier feel of a hybrid.

Claire Davies
Claire Davies

If you want a luxury hotel style mattress at home and either don’t have the budget for the Reylon (#3) or think it would be too soft for you, then the DreamCloud Luxury Hybrid is my top recommendation. I loved testing it so much that I bought one for my mother, who has been sleeping on it for over a year. She has arthritis in her spine and wrists, plus chronic back pain from her days as an upholstery seamstress bent over a sewing machine. While I found the DreamCloud Luxury Hybrid too firm at first, it was the opposite for my mother who said she “walked a little straighter and taller” after just one night on the DreamCloud. The lower back support and pressure relief are very good, but sleepers with chronic back pain who prefer a firm mattress should try the REM-FIT 500 Ortho Hybrid (#7) instead. Overall, the DreamCloud Luxury Hybrid is fantastic value at £649 for a double in the DreamCloud Black Friday sale with a lifetime warranty and year’s trial.

6. Best mattress for back pain

An orthopedic mattress that quickly relieves pressure on the back

Specifications

Price: From £510 on sale (£929 RRP)
Type: Hybrid
Best for: Back and front sleepers
Firmness (1-10): 8
Sleep trial: 200 nights
Guarantee: 15 years
Shipping: Free to room of choice

Reasons to buy

+
Incredible support
+
Orthopedic design
+
Good motion isolation
+
Big size range

Reasons to avoid

-
Limited cushioning
-
Can cause shoulder ache for side sleepers

Quick summary

Back pain can be a serious sleep disruptor but with the right mattress, you can enjoy better, more restful nights as well as fresher mornings. The REM-Fit 500 Ortho Hybrid Mattress is our top recommendation for sleepers with back pain, thanks to a firm feel and superior support that keeps your spine aligned all night long.

We rated the REM-Fit 500 Ortho eight out of 10 on the firmness scale, which means this is a firm mattress. And you can feel that all the way to the sides — we awarded full marks for edge support. With little in the way of cushioning, you lie on top of this bed rather than sinking in. This helps the lumbar region maintain alignment, although side sleepers might prefer the contoured support of the Levitex Sleep Posture Mattress (#10).

Claire Davies
Claire Davies

The DreamCloud Luxury Hybrid is an excellent all-rounder for people with general aches and pains and lower back pain, but it has a medium-firm feel (though it felt much firmer for me during the first couple of weeks of sleeping on it). If you want a properly firm mattress for back pain mattress, my testers highly rate the REM-Fit Ortho 500 Hybrid Mattress. We rate it as an 8/10 on the firmness scale compared to DreamCloud which we rate as a 6.5/10 on the same scale. There’s little give to the REM-Fit Ortho 500, so this is a mattress you sleep on top of rather than sinking into. That also means there’s little contouring here, so the DreamCloud Luxury Hybrid is the better choice if you want more of a touch of body-hug comfort with your back pain relief. Price-wise the REM-Fit is the cheaper of the two at £569.50 for a double size this Black Friday (the DreamCloud costs £649 for a double), which is an excellent price for a back pain mattress.

7. The best cooling mattress

If you sleep hot, this naturally cooling mattress is for you

Specifications

Price: From £950 RRP
Type: Hybrid
Best for: Back and front sleepers
Firmness (1-10): 7.5
Sleep trial: 100 nights
Guarantee: 10 years
Shipping: Free white glove

Reasons to buy

+
Cooler sleep feel

Fantastic lumbar support
+
Strong edges

Reasons to avoid

-
Strong off-gassing smell
-
Lacks contouring

Quick summary

The Panda Hybrid Bamboo uses advanced breathable materials to create a cooler sleep feel (plus a more eco-friendly build). Featuring bamboo infused memory foam, a breathable bamboo cover, and open springs, the Panda Hybrid achieves a cooler sleep feel all night long to take the best cooling spot in this guide.

The Panda Bamboo isn't cheap, but as a specialist bed with cooling technology, that's not surprising. And the Panda isn't all about the cooling. The edge support and motion isolation compare to some of the best in this guide, while the firmer feel provides excellent spinal alignment. It's not as firm as its eco-rival, the Simba Earth Escape at (#11), but lightweight side sleepers might still prefer the Emma Elite (#5) for cooler sleep.

Claire Davies
Claire Davies

Overheating in bed can lead to nights of broken sleep, and all that sleep deprivation will in time lead to an array of symptoms including fatigue, brain fog, and irritability. If you’re dealing with night sweats or hot flashes (flushes) then a good cooling mattress should be top of your shopping list. Panda London is arguably best known for its bamboo pillows, but the Hybrid Bamboo Mattress Pro delivers an excellent combination of cooling comfort and support. My lead tester does warn that it’s on the firmer side, so if you want a softer cooling mattress you’re better off with the Emma Elite (#4). The Panda Hybrid Bamboo Pro is slightly cheaper at £903 for a double this Black Friday though (a double Emma Elite is on sale for £1,024).

8. The best for hip pain

This specialist mattress cradles the joints for fresher mornings

Specifications

Price: From £549 RRP
Type: All-foam
Best for: Back and side sleepers
Firmness (1-10): 8
Sleep trial: 44 nights
Guarantee: 5 years
Shipping: £30

Poor extras

Quick summary

The Levitex Sleep Posture Mattress is an all-foam bed, but it's not a memory foam. At least, that's according to the founders of Levitex, who created the exclusive Levitex foam used in each mattress to improve sleep posture and avoid the pitfalls of memory foam.

That's a lofty ambition, but our review team agreed that this is one of the best mattresses for joint and back pain (especially if you don't want the super firm feel of the REM-Fot 500 Ortho at #7). The dense high resistance base foam lends the entire bed a supportive feel, while the upper layer of Levitex foam gently yields to pressure to cradle the joints. Our testing team found it comfortable in all sleep positions, although the thinner build (just 20cm) might be too short for heavier side sleepers.

Claire Davies
Claire Davies

If you don’t like the quicksand-type feel of traditional memory foam but you also want a contouring, body-hug mattress, the Levitex could be your ideal choice. It’s made from patented Levitex foam developed to help people with joint and back pain to sleep more comfortably. The REM-Fit 500 Ortho tested better amongst our review panel for back pain relief, but it was a very close call between that model and the Levitex Sleep Posture Mattress. The Levitex has a similar firm feel to the REM-Fit (we rate both as an 8/10 on the firmness scale) but crucially it has a bit more ‘give’. So you’ll still sleep on top of the mattress, but you’ll also have a little cushioning comfort to reduce all those painful pressure points. The trial period is shorter 44 nights (REM-Fit offers 200 nights), and it’s more expensive at £759 for a double compared to £569.50 for the REM-Fit this Black Friday. However if you want a mattress that delivers a rare combination of firmness and contouring, then I think the Levitex is worth considering.

9. The best natural mattress

For eco-conscious stomach and back sleepers seeking luxury support

Specifications

Price: From £879 on sale (£1,099 RRP)
Type: Hybrid
Best for: Back and front sleepers
Firmness (1-10): 8
Sleep trial: 200 nights
Guarantee: 10 years
Shipping: Free to room of choice

Reasons to buy

+
Eco-friendly materials
+
Full-body support
+
Luxurious finish

Reasons to avoid

-
Too firm for side sleepers
-
Weaker edge support

Quick summary

The Simba Earth Escape Mattress is an eco-friendly bed that uses wool, flax, and hemp to create a luxurious sleep experience. Plus a Simba spring base, which utilizes the latest technology to ensure total support that's also better for the environment.

Despite the somewhat unusual material choices, the Simba Earth Escape has a luxurious look to rival the Relyon Bridgwater (#3). The wool-viscose tufted cover has subtle cushioning, but the overall feel is firm — we rated it eight out of 10. But it's plusher than other firm beds, such as the REM-Fit 500 Ortho (#7), giving it slightly more cushioning for back sleepers and heavier side sleepers. Multiple spring layers (including several micro coil layers) ensure excellent lumbar support, but things are a little weaker at the edges.

Claire Davies
Claire Davies

Simba’s Earth range is an excellent addition to the brand’s growing line of mattresses. I’ve recently slept on the most expensive model in the Earth range, the Simba Earth Apex and rate it as one of the best mattresses I’ve ever tested (review coming soon), but my sleep staff writer Ruth slept on and tested the Emma Earth entry-level model. She rates it highly as a fantastic eco-conscious luxury mattress for stomach sleepers. According to Ruth, the “plush tufted top provides deep pressure relief at the hips and lower back while the firmer build keeps your spine supported.” Despite the unusual materials (wool, flax, and hemp aren't your regular mattress filling) the Earth Escape is comfortable from the start, though side sleepers might want a few layers of foam cushioning. For a cheaper hybrid that uses natural materials, I recommend the Panda Hybrid Bamboo Mattress Pro at £903 for a double compared to £1,274 for a double Simba Earth Escape.

Also tested and recommended

The mattresses below are the highest performers from all the other mattresses we've tested over the last few years. While these mattresses performed well in our tests, they were ultimately beaten by the ones above. But if you can't find the right mattress for you in our main guide, these are worth considering.

Brook + Wilde Suprema Mattress

Brook + Wilde Suprema Mattress ★★★★½
The luxurious Suprema is a nine layer made-to-order mattress with three firmness levels to choose from and a more sustainable build. Expect a few days to break it in, but our testers loved the pressure relief. Edge support is a weakness (the Relyon is better if you want a premium bed with strong edges), but the various firmness levels give this mattress an unusual versatility.

Read more: Brook + Wilde Suprema Mattress review

Nectar Hybrid Mattress

Nectar Hybrid Mattress ★★★★½
The Nectar Hybrid is a competitively priced medium -firm mattress with decent temperature regulation and surprisingly good motion isolation. It's just edged by the DreamCloud (#6) which has a stronger all-round performance, but is still a good choice for side and back sleepers.

Read more: Nectar Hybrid Mattress Uk review

Tempur-Pedic Tempur Hybrid Elite

Tempur-Pedic Tempur Hybrid Elite ★★★★½
Delivering deep pressure relief for achy joints, the Tempur-Pedic Tempur-Hybrid Elite is a luxury alternative to the Levitex Mattress (#10) for those who prefer sink-in foams. Sizes are limited, so shop this mattress while you can.

Read more: Tempur-Pedic Tempur Hybrid Elite mattress review

Emma Original Mattress

Emma Original Mattress ★★★★
A soft and squishy all-foam mattress, the Emma Original is ideal for side sleepers on a budget (even if it does have a slight issue with overheating). Emma no longer sells the Original, but you can still find a few random sizes in the clear out sale, and this mattress is available on several third-party sites.

Read more: Emma Original Mattress review

Nectar Essential Hybrid Mattress

Nectar Essential Hybrid Mattress ★★★★½
An entry-level hybrid, the Nectar Essential can't compare to the DreamCloud (or even the Nectar Hybrid), but its medium-firm feel is great for back sleepers and the price is hard to beat.

Read more: Nectar Essential Hybrid Mattress review

Nectar Premier HybridMattress

Nectar Premier Hybrid Mattress ★★★★
Sitting at the top of Nectar UK's hybrid line, the Premier Hybrid is a best seller that has a memory foam 'hug' combined with a bit of bounce — for those who want the best of both worlds. However, the support isn't quite as strong as the comparable DreamCloud (#6).

Read more: Nectar Premier Hybrid Mattress review

Lola Cool Hybrid Mattress

Lola Cool Hybrid Mattress ★★★★
With a springy, bouncy sleep surface, the Lola Cool Hybrid suits combination sleepers who like freedom to move around in the night. However, the lack of contouring means it doesn't have the pressure relief of a cooling hybrid like the Panda Bamboo Mattress (#9).

Read more: Lola Cool Hybrid Mattress review

Otty Pure Hybrid Mattress

Otty Pure Hybrid Mattress ★★★★
Featuring natural bamboo and charcoal, the Otty Pure Hybrid is a breathable mattress that we rated highly for temperature regulation. However, it's firmer than expected, lacking the wider appeal of the equally cool Panda Bamboo Mattress (#9).

Read more: Otty Pure Hybrid Mattress review

Eve Premium Hybrid Mattress

Eve Premium Hybrid Mattress ★★★★½
The Eve Premium Hybrid sits at the firmer end of the medium-firm spectrum, with minimal sinkage and only light contouring. It's a good alternative to the Simba Earth Escape Mattress (#11) if you're a stomach sleeper on a tighter budget

How we test mattresses

The Tom's Guide mattress review process is editorially independent and not influenced by third parties. To ensure unbiased product recommendations, we test every mattress in several key areas: pressure relief, support and comfort, temperature regulation, edge support, motion isolation, and durability. For each review, our lead tester spends a minimum of three weeks on the mattress, which is roughly how long it takes the body to get used to a new bed.

Comfort and firmness are subjective, so alongside our lead reviewer, each bed mattress is tested by a trusted panel. This panel is made up of people with different body types and sleep styles, to ensure every preference is taken into account.

Our testing team includes side, back, stomach, and combination sleepers, as well as people with different body types. This allows us to get a well-rounded view of how each mattress performs for a variety of people.

We also run a series of objective tests, using weights. We can then compare these results to other mattresses we've tested. In addition, we analyze the public reviews for each mattress, to see how real-world customers are responding. We then rate the mattress out of five, based on the data collected and the performance compared to other mattresses we've reviewed.

You can learn more about our testing process in our mattress methodology. This testing focuses on the following three processes:

  • Each mattress is tested across key areas: pressure relief, comfort, support, motion isolation, edge support, and temperature regulation.
  • We analyze available user reviews to understand what customers think of the mattress, looking for recurring issues / features to explore in our tests.
  • We fact check any support or comfort claims made by the brand.

How to choose the best mattress for you

The guide above contains our favorite mattresses. These are the ones our team have slept on, tested, and loved. But just because we think a mattress is the best doesn't mean it's going to be the right choice for you. So how do you find the perfect mattress?

Our number one piece of advice is to opt for a mattress with a sleep trial. A sleep trial gives you a period of time (typically 100 nights) to test the bed in your own home. If you don't like it, you can send it back for a refund. Some brands charge a small fee for these returns, but many offer it for free. Every bed in this guide includes a sleep trial.

When choosing a mattress, the primary factors to consider are:

  • Your sleep position
  • Mattress firmness
  • Your weight
  • Your sleep needs
  • Your budget

How you prioritize these factors will depend on your own individual circumstances. If you have no health issues and a tendency to sleep well no matter where you are, a standard bed in a box (within your budget) might suit you fine. But if you often struggle to get a good night's rest, finding the right mattress can transform your sleep.

Back to top ▲

Sleep position

Sleep position is one of the first things to consider when buying a mattress. There are four common sleep positions: side, back, stomach, and combination (someone who regularly moves between positions). Understanding your sleep position can help you understand what mattress will suit your needs.

  • Side sleepers need ample pressure relief at the shoulders, hips, and knees so tend to prefer medium feel mattresses with plenty of contouring. Memory foam mattresses are often a good choice
  • Back sleepers benefit from medium-firm mattresses with strong lumbar support. Both hybrid and memory foam mattresses can suit back sleepers, but avoid softer foams.
  • Stomach sleepers require strong support at the hips to keep the spine comfortable. Opt for medium to medium-firm mattresses if you have a lighter build, or a medium-firm to firm mattress if you have a heavier build.
  • Combination sleepers need a mattress to suit different sleep styles, and medium-firm hybrid and all-foam mattresses tend to be good all rounders. Good motion isolation is another priority, so when you move around you don't wake anyone else in the bed.

Mattress firmness

Mattress firmness refers to how hard or soft a mattress is. We judge it on a scale of one to 10. One refers to a mattress that's marshmallow soft, while 10 is as hard as a rock. These ratings are subjective (weight plays an important role here, which we'll discuss below), so when determining firmness we ask a range of sleepers with different body types and preferences how they experience the bed.

There's no good or bad firmness rating, and no easy answer to the question 'how firm should a mattress be?' Let's take a look at the different firmness ratings and who they benefit:

1 to 3.5 out of 10: These are super soft mattresses that you really sink into. Mattresses this soft are typically best for lightweight side sleepers who enjoy feeling 'hugged' by the bed, but it's important to ensure you're still getting enough support. Excess sink can result in back ache.

4 to 4.5 out of 10: Medium-soft mattresses, these beds have plenty of contouring but shouldn't leave you feeling like you'll fall through the mattress. These mattresses suit side sleepers with light to average builds.

5 to 6.5 out of 10: True medium mattresses that balance contouring with support. Side sleepers and back sleepers can both benefit from a medium mattress and they're also good for bed sharers.

7 to 7.5 out of 10: These medium-firm beds prioritize strong support and often have minimal sink. Good for sleepers with back pain and front sleepers. However, side sleepers might wake up with numb arms on these beds.

8 to 9.5 out of 10: Firm mattresses are often beds you lie on top of, with almost no contouring but plenty of support. They're good for stomach sleepers who need stability at the hips, plus those with a bigger build.

10 out of 10: Extra firm mattresses are rare and rock hard — you might feel like you're sleeping on the floor. Some back and stomach sleepers prefer this type of build, but it's a divisive feel.

Back to top ▲

Weight

Modern mattresses are typically multi-layered designs. The upper layers are the comfort layers, providing contouring and pressure relief. The base layers contribute to the overall stability and support of the mattress.

Sleepers with a lighter build will often benefit from the extra cushioning of a softer mattress, while those with an average build tend to prefer medium to medium-firm mattresses. Sleepers with a heavier build (over 230lbs), benefit from the superior full-body support of a firm mattress.

Sleep needs

Sleep needs vary from person to person, so it's important to consider what you prioritize in your sleep. Bed sharers should look for a mattress with good motion isolation, which will absorb movement so you can't feel your partner toss and turn.

Hot sleepers need a mattress with cooling features, to help absorb and dissipate heat throughout the night. Sleepers with back pain should consider a bed with enhanced lumbar support, while those with limited mobility can benefit from strong edge support.

The right mattress won't stop insomnia or cure your back pain, but it can help you enjoy comfier rest.

Budget

No matter your budget, it's still important to remember the above factors when choosing your mattress. If you have a tight budget, consider the features that are most important to your sleep needs — whether that's contouring or support or a breathable build — and use that to find a mattress within your price range that's right for your sleep style.

Mattress buying advice

A good mattress can be an investment purchase, and as sleep is essential to our wellbeing, it's important to get it right. Here our team of sleep experts and mattress testers answer all your questions, including what the different types of mattress are, how to find the right mattress for you, and when is the best time to buy a mattress.

What are the different types of mattress?

Mattresses come in many different forms, and there's no singular 'best mattress type'. Below are the most common types of mattress, including mattresses in a box (which come rolled and packed) and traditional flat mattresses:

Memory foam mattresses
Memory foam mattresses consist of multiple layers of polyurethane foams. They're known for their cushioning and pressure relief, with traditional memory foams delivering a 'body hugging' feel. Softer memory foam mattresses are often recommended for side sleepers, but there are firmer memory foam mattresses that offer support for front and back sleepers.

Dense memory foams absorb movement, making them a good choice for bed sharers. However, they can also hold onto heat. If you're a hot sleeper considering an all-foam bed, look for one with specialist cooling tech. Memory foam mattresses are typically cheaper than comparable hybrid bed. Learn more with our guide 'what are memory foam mattresses and are they worth it?'

Hybrid mattresses
A hybrid mattress combines layers of cushioned comfort materials (often memory foam, but sometimes natural materials such as wool or latex) with supportive springs. These springs make hybrid mattresses bouncier and more breathable than all-foam beds.

The bouncy feel makes it easier to move around on a hybrid, but it can be frustrating if you share a bed. The open coils allow for ample air circulation, so hybrid mattresses tend to sleep cooler than foam beds, but they do lack the deep cushioning hug some people look for in a mattress. Hybrid mattresses are typically more expensive than all-foam models.

Innerspring mattresses
Innerspring mattresses use coils to create a bouncy and buoyant feel with plenty of air circulation. These traditional style mattresses are built with either interconnected springs or pocket springs (in which each coil is placed in an individual pocket).

Innerspring mattresses are best for back and stomach sleepers, as they lack the cushioning side sleepers need for pressure relief. These models are becoming less popular, but they are generally budget-friendly beds.

Latex mattresses
The most popular type of organic mattress, latex beds replace polyurethane foams with natural latex foams. These foams are bouncy and breathable with ample support and excellent durability, but without the sink-in feel of a traditional memory foam.

Latex mattresses are typically premium models and can cost several hundred pounds more than similar beds constructed with classic foams. However, as mentioned, latex is known for its durability, so you can potentially get a lot of bang for your buck.

What mattress type is best?

There is no mattress type that's better than the other, as each model can suit a different sleep style — the best mattress for you won't necessarily feel as comfortable for someone else. For this reason, ensure you always get a mattress trial, so you can test the bed over the course of several weeks and see if it's right for you.

With that said, we know from our testing that there are some general trends in comfort. Lightweight side sleepers typically benefit from soft to medium mattresses, often with ample cushioning. People of average body weight (around 130 to 230lbs) tend to prefer medium-firm mattresses, while those with heavier builds should consider firm mattresses.

Where is the best place to buy a mattress?

It used to be unusual to buy a mattress online, but the rise of beds in a box has made it much easier to buy a high-quality mattress online and get it delivered straight to your door. In our experience, the best place to buy a mattress is online, where you can find direct to consumer brands offering excellent prices on beds for every sleep style.

Without the cost of a brick and mortar store, online mattress brands can save money — and this saving is passed onto the consumer. Some sleep brands also take a dual approach, selling the full line up of mattresses online and a few select models in store.

Most online-only mattress brands sell 'mattresses in a box', in which the bed is compressed, wrapped in plastic, and boxed. Once removed from the packaging the mattress will spring back into place and gradually inflate to its full height.However, some brands (including Simba) do sell flat mattresses. Often these beds are sold with white glove delivery, so you can avoid the setup process.

There are also third-party online mattress retailers, where you can sometimes score a better price than shopping direct from the manufacturer. However, in our experience the brand will typically offer superior benefits, such as trial and warranties, plus better after care.

If customer service is a priority, there are definite advantages to shopping in store. While many online mattress retailers offer live chat boxes and phone help, they're not always reliable.

Wherever you choose to buy your mattress, don't forget the sleep trial. A trial period of 30 days minimum allows you to really get to know the mattress, so you know it's going to be right for you.

When is the best time to buy a mattress?

The best time to buy a new mattress is traditionally during the Black Friday sales. This is when we expect to see major discounts from all the best sleep brands and you can often score the lowest prices of the year. Cyber Monday — the Monday after Black Friday — is another good time to pick up a deal.

Other holiday sales events pop up throughout the year, including the Boxing Day sales, Easter sales, and bank holiday savings days. These sales periods aren't quite as major as Black Friday, but they can still be a good chance to get a mattress for less (especially if you need a bed before November).

Most sleep brands run sales regularly throughout the year, although outside Black Friday, we can't always predict when these offers will appear. But if you're looking to save on an online mattress, you're rarely that far away from a discount.

What are the best mattress brands in the UK?

We've tested beds from all the best and most popular brands in the UK, including Simba, Emma, Panda, Nectar, DreamCloud, Eve, and Tempur-Pedic. These brands all offer mattresses to suit a variety of sleep styles and budgets, with regular sales throughout the year.

It's a Simba mattress currently occupying our top spot, and Simba is one of our favorite UK mattress brands (it's also recently expanded to the US). Simba Sleep UK is a B Corp Certified brand and the beds are designed and manufactured in the UK. Simba mattresses come with a 200-night trial and a 10-year guarantee.

How often should you change your mattress?

This guide can help you find a new bed when your old mattress has reached the end of its life — but how often should you replace your mattress? This depends on a number of factors, including the type of mattress. A mattress with a thick supportive base, for example, is likely to last longer then a mattress with thinner support.

How you care for the mattress also effects longevity. Regular cleaning and mattress rotation (if necessary) can prolong the life of your bed. We also recommend investing in a mattress protector. Not only can this improve longevity, but it also makes your bed significantly easier to clean.

A high-quality memory foam mattress can often last for up to 10 years. Memory foam mattresses don't contain springs, so you won't experience the creaking that indicates your hybrid or innerspring bed is past its best. However, memory foam beds can start to sag, and you're likely to notice the temperature regulation and edge support deteriorating with use. Regular rotation can help limit sagging.

Hybrid mattresses, which combine springs and foams, tend to deteriorate slightly quicker than all-foam beds. We recommend replacing a hybrid mattress every eight to 10 years. You might start to hear the problems before you feel it — hybrid mattresses can start to squeak and creak with age. The upper foam layers are also susceptible to sag, but regular rotation can help limit the problem.

Innerspring mattresses have the lowest longevity of all bed types, and will often last around five to seven years. Made entirely from springs, expect to hear some creaking after a few years. Flipping an innerspring mattress every few months can help prolong its lifespan.

Conversely, latex mattresses are the most durable. We expect a latex mattress to last for up to 20 years. Latex foams are naturally dense and durable, less prone to sinking than other forms of foam. However, many latex beds also contain springs, which can wear out faster than the foams.

How much should I spend on a mattress?

At Tom's Guide we think mattresses are an investment that will pay you back with good rest — for that reason, we recommend paying what you can afford for a quality mattress.

It is possible to pick up a good mattress for less than £300 for a double, but expect to make certain concessions. These mattresses typically lack the longevity and comfort of pricier builds. They tend to be best for guest rooms and teenage bedrooms.

Increasing your budget to the mid-range category opens you up to a wider variety of mattresses, made with better quality materials. We consider a mid-range mattress around £400 to £600 for a double, while an upper mid-range mattress can set you back up to £800. Although more money upfront, these beds will typically stay comfortable and supportive for longer.

A premium mattress costs upwards of £800 for a double (and this is where you'll find our top pick, the Simba Hybrid Ultra). These mattresses tend to be the cream of the crop, although a high price tag doesn't necessarily indicate the best mattress for your sleep style.
