Choosing the best mattress for your budget and sleep is easier than it has ever been, and that’s because mattresses are of a better quality now compared to even a few years ago. We have reviewed and researched the latest UK mattresses, and have looked through thousands of user reviews, to bring you this guide to the best options. These include comfy memory foam models, as well as innovative hybrid mattresses and traditional innerspring models. A good mattress needn’t cost much either - our number one choice, the Emma Original, is currently priced from just £274. 

Here we rank the UK’s best mattresses for all budgets and sleeping positions. So whether you want to upgrade your main bed with something more luxurious, or you want to make your guest bedroom a little comfier for family and friends, we have you covered. These mattresses work with a wide range of bed frames and bases too, and ordering is simple - in just a few clicks you can have a new mattress delivered to your door.

Our best tip for buying a mattress online is to go with a trusted brand that offers a risk-free mattress trial period. 60 nights is the shortest trial of the mattresses featured here, with 100 nights being the average and 365 nights being the longest. It can take your body around three weeks to get used to a new bed, so these trial periods help you figure out if you really have chosen the best mattress for you. 

On that note, if you share a bed, you’ll need to take both of your comfort and support needs into account. You may find that a medium firmness hybrid mattress is your ace card, though all of the below choices offer high levels of comfort, support and pressure relief. Let’s look at our top picks now...

The best mattress UK 2021 – as rated by experts

1. The Emma Original Mattress UK

The best mattress overall – it suits all sleepers and budgets

Type: Bed-in-a-box
Firmness (1-10): 6.5
Material: Memory foam
Height: 25cm
Availability: Online
Trial length: 200 nights
Warranty: 10 years
Best for: All sleeping positions; couples
RRP: £499 to £899
Reasons to buy
+Affordable at every size+Good motion isolation
Reasons to avoid
-Heavier bodies may need a firmer pick-Sleeps a little warm

Emma is one of the most popular mattress in a box brands, and the Emma Original is the cheapest model it sells. If you want a good all-rounder memory foam mattress that suits all sleeping positions, this is the best choice. In particular, because it’s on the softer side of medium firm, it comfortably cradles your hips and knees when you sleep on your side. And while it does provide a comforting hug feel, it won’t swallow you, making it suitable for back and stomach sleepers too.

All of that ample cushioning means the Emma Original is great at absorbing motion, so restless couples will have a better time sleeping on this mattress  because you won’t feel each other moving around as much. The all-foam Emma also promotes healthy spinal alignment, which is important for your posture over the long-term (an unsupportive mattress can wreak havoc on your back). 

While standard memory foam mattresses can sleep hot, the Emma uses open-pore foam to regulate in-bed temperature. It certainly felt more breathable than other foam models we’ve slept upon, but this isn’t a proper cooling mattress. So if you sleep very hot, look at the Eve Premium Hybrid below as this has a more powerful cooling performance.

Like the Nectar Memory Foam Mattress (our No 2 pick), the Emma’s most attractive feature is the price. It’s the cheapest model in our best mattress UK guide, making it brilliant value for money, second only to the Nectar. The difference is that Nectar runs bigger discounts and also gives you free bedding gifts. Still, if you want a good yet affordable mattress for your bedroom or guest room, the Emma Original is a fantastic choice. For the latest savings, read our guide to the best Emma mattress sales and discounts.

2. Nectar Memory Foam Mattress UK

The best mattress for unbeatable value

Type: Bed-in-a-box
Firmness (1-10): 7
Material: Memory foam **Height:** 25cm
Availability: Online
Trial length: 365 nights
Warranty: Forever
Best for: All sleeping positions; couples; restless sleepers
RRP: From £569 to £929
Reasons to buy
+Isolates motion from your partner+Comfy ‘body hug’ feel+Lifetime warranty
Reasons to avoid
-Too firm for some lighter bodies

The Nectar Memory Foam Mattress is fantastic value for money and is the best option for anyone wanting a comfy, all-foam mattress for less. As a medium firm mattress, it supports most sleeping positions (though it’s especially comfy for side sleepers) and hits that sweet spot between all-body comfort and proper spine alignment. Nectar also runs a 365-night trial (love it or get your money back), so there’s nothing to lose here.

The Nectar Memory Foam Mattress is made up of five layers of foam that contour to your body and deliver pressure relief around your back, hips and shoulders. This means less aches and pains for you when lying down and upon waking. Unusually for an all-foam mattress, the Nectar doesn’t overheat – we asked a self-confessed hot sleeper to snooze on this one and they didn’t end up a sweltering mess.

The Nectar is good for couples too, especially if you or your partner toss and turn a lot in bed. Why? Because it absorbs motion well (so you won’t feel the other person moving so much). There’s also decent edge support, so you can both spread out and enjoy your wider mattress space. 

Value for money is the ace card here though. With regular Nectar mattress deals and discounts of up to £520 off plus free gifts worth around £315, the Nectar Memory Foam Mattress out-guns every other pick in our best mattress UK guide. The Emma Original (see above) is cheaper, but it doesn’t come with free gifts.

If you’re unsure about sleeping on an all-foam mattress or need a firmer option for back support, take a look at the Eve Premium Hybrid (No 4). It uses coils as well as foam, so it’s more breathable. Just keep in mind that the Eve is more expensive than the Nectar and the trial period is shorter.

Nectar Memory Foam: get 45% off for Black Friday

Nectar Memory Foam: get 45% off for Black Friday
From £312.95
- This is a bigger discount than we saw last month from Nectar, and like the Emma above it’s fantastic value for money. If you want bedding too, you can also save up to £735 on a Nectar Sleep Bundle in the brand's Black Friday sale. You'll also get a year's risk-free mattress trial and a market-leading lifetime warranty. 

Best mattress: The Simba Hybrid Mattress UK shown with blue Simba logo tag

3. Simba Hybrid Original Mattress

The UK's best hybrid mattress for all sleep positions

Type: Bed-in-a-box
Firmness (1-10): 6.5
Material: Springs, memory foam
Height: 25cm
Availability: Online
Trial length: 200 nights
Warranty: 10 years
Best for: Side sleepers, back sleepers, warm sleepers
RRP: £649 to £1,109
Reasons to buy
+Excellent support+Cooler feel than all-foam+Huge range of mattress sizes
Reasons to avoid
-Spot-clean only

The Simba Hybrid proves that you don’t have to pay over the odds for a great night’s sleep. By design, hybrid mattresses are more breathable than all-foam models – because they use coils or springs, air moves more freely within the mattress – so the Simba is a better choice for people who sleep warm. The Simba Hybrid also uses graphite-infused memory foam, and graphite is a material that aids cooling by dissipating body heat. If heat doesn’t build-up, the mattress remains cooler.

Hybrids are also firmer by design than all-foam models, making them more supportive for heavier bodies that would otherwise sink too much into a softer mattress (not great for your spine). The Simba Hybrid uses a combination of 2,500 Aerocoil springs and premium foam to deliver this level of consistent support. There’s a support layer and a support base at work here, giving this hybrid a firmer feel from the ground up.

The Simba Hybrid is also popular with people wanting a more eco-friendly mattress, as it uses Simba-Pure CertiPUR certified foam that’s free from toxins that are harmful to you and the planet. There are other organic mattresses worth looking at if you want a more natural sleeping experience (namely, latex mattresses), but these are much more expensive. For the latest savings, read our guide to the best Simba mattress sales and discounts.

The Simba Hybrid has amassed over 92,000 user reviews (as of Sept 2021), generating an average rating of 4.8 out 5 stars, and customers highlight its comfort, support and cooling. The Eve Premium Hybrid is another highly rated pick for cooling and back support, but out of the two we’d recommend the Simba. The brand also makes one of the best weighted blankets for calmer sleep, which could be a cosy addition to your new mattress.

Simba Hybrid mattress: 45% off Black Friday sale

Simba Hybrid mattress: 45% off Black Friday sale
From £219.45
- Simba runs regular discounts that range from 20-41%, and this is the highest saving we have seen from the sleep specialist recently, with a double size Simba Hybrid now costing £483.45. Simba hybrid mattress bundles are on sale too at 50% off, with savings of up to £1,208 depending on the bundle you buy.

4. Eve Premium Hybrid

The best mattress for hot sleepers

Type: Bed-in-a-box
Firmness (1-10): 7.5
Material: Spring and foam
Height: 28cm
Availability: Online
Trial length: 100 nights
Warranty: 10 years
Best for: Hot sleepers, back support
RRP: From £978 to £1,247
Reasons to buy
+Breathable and cool+Supportive to the edge+Machine washable top panel
Reasons to avoid
-Only three sizes available

Proper cooling mattresses are very expensive, but the Eve Hybrid Premium does a similar job by using top layers of graphite-infused cushioning foam; graphite is a material that quickly draws away excess heat. 1,500 pocket springs toward the bottom of the Eve also keep the air moving freely, which increases how breathable this mattress is. 

As the Eve Premium Hybrid is firmer than all-foam models like the Nectar and the Emma Original, you sleep right on top of the mattress where it’s cooler. For these reasons, we recommend the Eve Hybrid Premium as the best choice for people who sleep very hot but don’t have the budget for a high tech cooling mattress. (Compared to the growing US market, UK cooling mattresses aren’t as widely available yet.)

That much firmer feel also makes the Eve Hybrid Premium a good choice for heavier bodies that need extra support to stop them sinking too far into the mattress (not a healthy move for your spine). People with lighter weight bodies may find it too hard though, especially lightweight side sleepers - look at the Emma Original above instead, which offers more cushioning and pressure relief for hips and knees. Just keep in mind that the Emma isn’t as breathable as the Eve or Nectar Memory Foam.

Does your current mattress give you a sore back? Sounds like you need more pressure relief, and the 1,500 pocket springs in the Eve Premium Hybrid will dish this out while keeping your spine aligned in a healthy yet comfy way. The Brook + Wilde Lux (No 5) is worth looking at too, as it offers enhanced shoulder and back care support. Motion transfer is also very good on the Eve, so you shouldn’t be woken up as much by your partner changing position during the night. For the latest offers, see our guide to the best Eve mattress sales and discount codes.

Eve Premium Hybrid: up to 35% off for Black Friday

Eve Premium Hybrid: up to 35% off for Black Friday
Save up to £249 - This Eve Black Friday mattress sale saves you £196 on the double size Premium Hybrid (now £782), and up to £249 on the super king (now £998). This is better than September's offer, which gave you 20% off orders worth over £450. Eve offers a 100-night mattress trial, so you’ll have ample time to test yours at home.

5. Brook + Wilde The Lux

The best luxury mattress with your choice of firmness

Type: Mattress-in-a-box
Firmness (1-10): Soft (3), Medium(5), Firm (7)
Material: Memory foam, pocket springs
Height: 28cm
Availability: Mainland UK only
Trial length: 100 nights
Warranty: 10 years
Best for: Soft – side sleepers, small build, lighter weights; Medium – back and side sleepers; Firm – front sleepers, average/heavier builds, people with back pain
RRP: From £599 to £999
Reasons to buy
+Three levels of firmness available+Relieves pressure on your body+Dedicated shoulder support
Reasons to avoid
-Only four sizes available

Luxury sleep brand Brook + Wilde manufactures its mattresses in the UK and focuses on making the best mattresses for relieving pressure across your body so that you feel more comfy during sleep. The six-layer Lux comprises a sturdy foam base, followed by a layer of 1,000 pocket springs (you need these for a little bounce). Next up is a central layer of foam moulded into a wave design to keep your spine aligned and to boost support and comfort to your shoulders. 

Brooke + Wilde has also added in 2,000 mini springs that respond to your every move in bed (again, to reduce pressure points), and a layer of cooling memory foam to make the Lux more breathable. That foam pulls double duty to reduce how much you feel your partner fidgeting next to you while you’re trying to sleep. Put another way, if you sleep warm, or you need back and shoulder support, or if you share a bed with a restless sleeper, the Brooke + Wilde Lux could make a noticeable difference to how well you sleep.

At £899 for a double size six-layer mattress, the Brook + Wilde Lux is reasonably priced compared to its competition. We particularly like the choice of three firmness levels, and the addition of dedicated shoulder support from the brand’s own Wave technology. If the mattress isn’t right, Brook + Wilde will exchange it for a different firmness or give you a full refund but only after 30 days of the 100-night trial. 

Delivery takes place within two weeks for the Lux (it’s up to eight weeks on the brand’s Ultima mattresses), so if you need a new mattress asap, and you want a hybrid model we’d suggest the Simba instead. It has a similar price (cheaper with a discount), but admittedly it isn’t as luxurious as the Brook + Wilde.

Brook + Wilde The Lux: save 45% on mattresses over £599

Brook + Wilde The Lux: save 45% on mattresses over £599
Save up to £1,039.60 - From now until Cyber Monday, you can save 45% on any other Brook + Wilde mattress as long as it costs £599 or more. There’s a huge saving on the 10-layer The Ultima premium mattress, and The Lux is also on sale with a double size costing £384.46. This is the biggest discount we have seen from Brook + Wilde, so now is a great time to buy if you want one of these luxury mattresses at the cheapest price.

Best mattress: Sealy Teramo Latex 1400 Mattress UK in white with grey edging

6. Sealy Teramo Latex 1400 / Nostromo 1400

A tall hybrid mattress that delivers all-night comfort

Type: Standard
Firmness: Medium-firm
Material: Innergetic latex, pocket coils
Height: 30cm
Availability: Online and in store
Trial length: None
Warranty: 5 Years
Best for: Back and stomach sleepers; heavier bodies
RRP: From £920 to £1,653
Reasons to buy
+Suits most sleep styles+Handles make it easy to transport+Regularly on sale
Reasons to avoid
-No trial period

Sealy is an established UK mattress brand, and the medium firm Teramo Latex 1400 (also known as the Nostromo 1400) is one of its more popular models. This comfy hybrid mattress takes its name from a layer of 1,400 cased pocket springs used to deliver proper spinal alignment and all-night pressure relief. A 2.5cm latex layer boosts comfort, support and cooling (latex is a naturally cooling material).

The cosy pillow top doubles down on that in-bed comfort, and because the Tencel cover is antimicrobial, it keeps dust mites at bay to ensure your mattress remains fresher for longer. At 30cm in height the Teramo Latex 1400 is also one of the tallest options in our best mattress UK guide, which is good news for comfort levels, but it does mean that you’ll need a deeper fitted sheet if you add on a bed topper.

One of the main issues when sharing a bed is space. Namely, that you and your partner have enough to feel comfortable during sleep. The Teramo Latex 1400 has a reinforced edge so that you can really spread out without feeling like you might tumble off the bed any second. It distributes weight evenly too, which is important for combination sleepers who shift position throughout the night. Why? Because if the mattress doesn’t redistribute your weight quickly, you could end up feeling more pressure (discomfort) on your body.

The Teramo Latex 1400 is a medium firm model that best suits back sleepers, stomach sleepers and people with a heavier body weight. If you’re a dedicated side sleeper or have a lighter weight body, and you aren’t completely sold on a hybrid, check out the Nectar Memory Foam Mattress or the Emma Original further up this guide. For a softer hybrid, choose the Brook + Wilde Lux in soft or medium.

Caring for the Teramo Latex 1400 is easy as it doesn’t need to be flipped, just rotated every 3-6 months (read our feature answering how often should you rotate your mattress for more). Rotating it is simple to do thanks to the reinforced handles on both sides. The Sealy Teramo Latex 1400 comes with a five-year guarantee and free delivery. Compared to the competition from newer brands, this Sealy mattress is more expensive, but it’s often on sale for up to 45%.

Best mattress: Tempur-Pedic Tempur Hybrid Mattress UK

7. Tempur-Pedic Tempur Hybrid

The best mattress for heavier bodies (and NASA fans)

Type: Standard
Firmness: Medium
Material: Advanced Tempur, Precision Micro Coils
Height: 21cm (Supreme); 25cm (Elite)
Availability: Online
Trial length: 100 nights
Warranty: 10 years
Best for: All sleepers; tall and heavy bodies; those needing extra postural support
RRP: From £1,159 to £2,639
Reasons to buy
+Superb pressure relief and comfort+Good range of sizes and lengths+Washable zip-off mattress cover
Reasons to avoid
-Long delivery period

The Tempur Hybrid is known for its full body contouring comfort and is the best choice for people with back and neck pain who need pressure relief in multiple sleeping positions. This Tempur comes in three versions: the Supreme (21cm tall), Elite (25cm) and Luxe (30cm). Each uses Advanced Tempur material - the brand’s famous pressure-relieving foam, originally developed by NASA to boost in-flight comfort. It also uses sci-fi-sounding visco-elastic cells that adapt to your posture during sleep, but there’s much more at play here.

In fact, there’s more sleep tech here than in any other model in our best mattress UK guide. Tempur-Pedic’s Dynamic Support technology, plus a series of pocketed micro coil springs, is responsible for comfort, while a DuraBase minimises motion transfer and keeps the entire mattress stable. If you have a heavier body, the Elite offers 3cm more Dynamic Support, plus 1cm more Tempur magic to boost your comfort. The Luxe version is the deepest, most plush of the three, and all three come in 10 different sizes, including longer models, making it an excellent choice if you’re tall. 

The removable mattress cover is another benefit as you can machine wash it (at temperatures of up to 60°C) to kill dust mites and other allergens. The Elite and Luxe models take this up a gear with a premium zippable QuickFresh cover. Either way, your actual Tempur mattress will be better protected from stains and bacteria.

As well as being known for high levels of contouring comfort, Tempur-Pedic mattresses have higher price tags. The Tempur Hybrid is no exception, but considering the average lifespan is 8-10 years on a model of this type, it’s a small price to pay for comfier sleep. You’ll get 100 nights to try the mattress for yourself, and if you change your mind, Tempur-Pedic will collect it and issue you a refund. Like the Sealy Teramo 1400 above, we often see the Tempur Hybrid mattress on sale, so it’s rare that you’ll have to pay full price.

Best mattress: The Otty Pure Hybrid Bamboo and Charcoal Mattress UK

(Image credit: Otty)

8. Otty Pure Bamboo and Charcoal Mattress

The best eco-friendly mattress

Type: Mattress in a box
Firmness (1-10): Medium-firm (6.5)
Material: Bamboo memory foam, activated charcoal, high-density foam, pocket springs
Height: 25cm
Availability: Online
Trial length: 100 nights
Warranty: 10-year limited guarantee
Best for: People with allergies; hot sleepers; anyone wanting a natural mattress
RRP: From £649.99 to £1,149.99
Reasons to buy
+Non-allergenic+Eco-friendly+Excellent support
Reasons to avoid
-Too soft for heavier bodies

The Otty Pure Hybrid Bamboo and Charcoal Mattress is an excellent choice if you’re looking for an eco-friendly mattress that uses natural, non-toxic materials to keep you cool without aggravating your allergies. For example, bamboo won’t aggravate asthma or sensitive skin like some synthetic mattress materials can. All the foam used in the Otty Pure Hybrid Bamboo and Charcoal Mattress is CentiPUR and Europur approved too, which guarantees they are free of high levels of toxins.

Otty has designed this mattress with three layers of foam to boost comfort for all sleeping styles (stomach, back, side, combi), and has infused it with a layer of 16cm pocket springs to deliver more support around your back, hips and shoulders and for your joints. Those springs also minimise motion transfer, which is a must if you’re sharing with a restless sleeper.

Feeling too hot in bed can really mess with your sleep, and the Otty Pure Hybrid Bamboo and Charcoal Mattress aims to combat this with a top support layer that marries bamboo memory foam with temperature regulating charcoal. There’s charcoal in the mattress cover too – it’s there to wick away sweat so that it doesn’t seep through and stain your mattress (those yellow marks that build up over time). 

Otty runs a 100-night trial, so you’ll have enough time to make sure this is the best mattress for your sleep. Delivery is free to your doorstep, but Otty charges an extra £10 if you want it delivered to your bedroom, whereas other brands like Brook + Wilde offer this service for free. You can also pay extra and have your old mattress collected (most UK mattress brands charge around £40 for collection). For what it offers, the Otty Pure Hybrid Bamboo and Charcoal Mattress is reasonably priced and definitely one to try if you want to make the switch to more natural sleep without paying the higher price for a fully organic mattress.

£357.49 at Otty

Otty Pure Hybrid: was from £649.99 £357.49 at Otty
Save up to £402.50 - If you want a more natural mattress for less, the Otty Pure ticks all the boxes. And at 45% off in the brand’s current sale, it’s one of the cheapest luxury mattresses in our guide. We have seen similar discounts from Otty in recent months, but even so, this is a superb saving on a highly-rated mattress suited to people with allergies, joint pain, and those prone to restlessness in bed.

Best mattress: The Silentnight Studio Original Mattress in white

(Image credit: Silentnight)

9. Silentnight Studio Original Mattress

A comfortable memory foam mattress from a trusted brand

Type: Bed-in-a-box
Firmness (1-10): 6
Material: Memory foam, Geltex
Height: 26cm
Availability: Online, in-store
Trial length: 60 nights
Warranty: 5 years
Best for: Hot sleepers, couples, those with aches and pains
RRP: From £399 to £699
Reasons to buy
+Suits all sleep positions+Cooling for hot sleepers+Vegan-friendly materials
Reasons to avoid
-Short warranty-Short trial period

Memory foam mattresses are a superb choice if you enjoy the sensation of being cradled in bed, but some of them do retain heat more so than hybrid mattresses. The Silentnight Studio Original Mattress side-steps the issue of overheating by infusing its foam layer with a cooling material called Geltex. This boosts breathability and dissipates heat. While this isn’t a full-blooded cooling bed, it is more breathable than standard all-foam models, just like the slightly cheaper Nectar Memory Foam Mattress (see No 2).

The Silentnight Studio Original Mattress offers medium firmness, meaning it suits almost all body types and sleep positions (medium to medium-firm is considered the sweet spot for mattress firmness). In addition to that Geltex-infused foam, you’ll be supported by a high-density foam base. This is responsible for most of the pressure relief you’ll experience across your back, neck and hips, plus your shoulders and knees when side sleeping. Weight will also be spread evenly across the mattress, so you shouldn’t encounter any premature sagging or dips in random spots.

The knitted fabric cover is hypoallergenic and infused with Purotex to ward off dust mites and other allergens. So like the Otty Pure Bamboo and Charcoal Mattress (above), the Silentnight Studio Original is one of the UK’s best mattresses for people with common allergies. It’s easy to care for too - because it’s a single-sided design, you won’t have to flip this one; simply rotate it every few months to spread out the wear and tear. The mattress will come boxed and wrapped in a protective covering, and as it’s made of memory foam you can expect some off-gassing when it’s first unpacked. We recommend opening a window during the unboxing and leaving it open for a few hours after. 

The only downsides here are the shorter than average mattress trial period (60 nights) and guarantee (five years), but neither are deal-breakers. If you want a good mattress from a trusted brand, and one that will mould to your unique body shape and weight to relieve pressure and any aches and pains, the Silentnight Studio Original Mattress is a good choice. We regularly see it on sale too, with a double size often reduced to less than £500. 

Best mattress: The Rem-Fit 500 Ortho Hybrid Mattress UK shown from the front

10. Rem-Fit 500 Ortho Mattress

The best mattress for fitness enthusiasts

Type: Mattress-in-a-box
Firmness: Firm
Material: Foam, pocket springs, fabric cover
Height: 190-200cm
Availability: UK only
Trial length: 100 nights
Warranty: 15 years
Best for: Those who need extra lumbar support
RRP: From £799 to £1,199
Reasons to buy
+Excellent spine support+Zoned pressure relief
Reasons to avoid
-Could be too firm for some

Rem-Fit has made its name as the go-to mattress maker for people who have intense workout routines and know that sleep is the key to better, faster recovery. The Rem-Fit 500 Ortho is perfect for this, but it’s also a great choice of mattress for enhanced back care. With edge-to-edge support, this hybrid orthopaedic mattress is constructed in layers that are not only stable, but cooling and breathable too. A layer of 15cm pocket springs helps minimise motion transfer if you share a bed.

Sleepers prone to back problems and general aches and pains will also benefit from the Rem-Fit 500 Ortho’s zoned pressure relief. That’s because it incorporates various densities into the top layer of memory foam to deliver targeted support for bonier areas while keeping your posture aligned. Other top features include open-cell memory foam to regulate temperature and prevent you waking throughout the night because you’re too hot. There’s also a breathable cover, which can be removed and machine washed.

If you prefer a softer mattress, the Rem-Fit 500 Ortho isn’t the best choice for you so look at the Nectar Memory Foam or Simba Hybrid instead. For fitness fans needing a supportive bed to boost recovery, and for people who have been advised to sleep on an orthopedic mattress to look after their back, the Rem-Fit 500 is an excellent choice. It also supports up to 20 stone in weight per sleeper, making it one of the best mattresses for heavier bodies, like the more expensive Tempur Hybrid (No 7).

£569.40 + free pillows at Rem-Fit

Rem-Fit 500 Ortho: was from £949 £569.40 + free pillows at Rem-Fit
Save up to £479.60
- This 40% saving on all Rem-Fit mattresses will net you a double size 500 Ortho for £559.40 (was £999). You’ll also get two free anti-allergy pillows worth £59 with your mattress purchase. Rem-Fit runs regular mattress sales at around 35-40%, so this current discount sits at the top end. Throw in the free gifts too, and it’s even better value for money on a memory foam mattress for proper back and neck support.

Best mattress: The Dormeo S Plus Evolution Mattress UK

11. Dormeo S Plus Evolution

The best dual-firmness mattress for choosy couples

Type: Mattress-in-a-box
Firmness (1-10): Medium/Soft, Medium, Medium/Firm, Multi
Material: Memory Foam, Ecocell Foam
Height: 23cm
Availability: Online and in store
Trial length: 60 days
Warranty: 15 years
Best for: Side sleepers (soft side), back sleepers (firm side), co-sleepers with different firmness needs
RRP: From £799.99 to £1,399.99
Reasons to buy
+Personalised comfort+Plush mattress top
Reasons to avoid
-Short trial period -No free returns

The Dormeo S Plus Evolution is designed for people who wake up often throughout the night because they can’t get comfy (or they don’t stay comfy for long). Even better, it has a clever trick up its sleeve: this innovative mattress is divided into two halves, each of which can be flipped to a softer or firmer surface. Simply unzip the cover and choose the side you each want. 

If that isn’t enough customisation, you can choose which end to have at the top. Dormeo’s all-foam Octasprings fall into zones, so we recommend keeping them closer to your head and neck for more bounce, or rotating the mattress the other way for more support at the shoulders.

The Dormeo S Plus Evolution’s Octaspring technology also delivers plenty of ventilation, as does the mattress’s breathable and elastic Ecocell foam. The mattress cover provides an anti-bacterial sweat-wicking layer that is also dust-mite resistant, making it ideal if you suffer from allergies. 

There’s lots on offer here, which is good considering the more premium price. There are two downsides though. The first is that there’s only a 60-night trial, which is nearly half as short as the other brands in our best mattress guide, but that should still give you a good feel for the mattress (experts recommend at least 30 days). Secondly, while delivery is free, you will have to pay to have the mattress returned if you change your mind. 

Even so, this is a great quality hybrid offering a lot of comfort customisation for couples. For the latest savings on this model and others, read our guide to the best Dormeo mattress sales and discount codes.

How to choose the best mattress for you

We don’t believe that buying a mattress is hard. In fact, we think it’s easier than ever and that’s because mattress manufacturers are constantly upping their game to stay one step ahead of the competition. By drawing up a shortlist of what to look for and what to avoid, you’ll find mattress shopping a lot more simple. Add to that how many bed-in-a-box brands offer long risk-free trials, and you have nothing to lose here. 

Choosing the best mattress for you begins with thinking about your current sleep challenges. Do you often wake up because you feel too hot or because you can’t get comfy? Does your restless partner wake you up with their tossing and turning? These are all legitimate criteria to keep in mind when picking a new mattress, and there are plenty of memory foam and hybrid models that can eliminate these problems for you. 

Here is our mattress checklist that you may find helpful to run through before choosing your shortlist of potentials:

1. What is your dominant sleeping position?
Knowing this will help you discard any mattresses that are designed to support you as a side, stomach or back sleeper. Most mattresses are comfy and supportive for all positions, but you’ll find that they normally excel at one or two. For example, we love memory foam models for extra cushioning during side sleeping, while hybrids offer better support for back sleepers.

2. Are you sharing with a restless sleeper?
If so, pay close attention to how your chosen mattress is designed to isolate motion. Your sleep will be so much better and less disturbed if you pick a mattress with ample foam and springs to isolate motion and to evenly distribute weight from you and your partner across the entire mattress. 

3. Do you sleep hot?
This is a growing issue for many sleepers, and multiple health factors (and certain medications) can lead us to sleep hot. Some people naturally ‘run hot’ anyway, and it’s the same during sleep. At the very least, choose a mattress that is breathable. Look for materials such as open cell or perforated foam, or gel-infused foam.

In the UK we’re starting to see the inclusion of cooling materials such as copper and graphite, which used to be the sole domain of proper (and very expensive) cooling mattresses. Generally speaking, hybrids are more breathable than foam as air flows better in and around their coils or springs.

4. What is your budget?
Having a good idea of how much you’re willing to spend on the best mattress for your sleep will help you narrow down your choices quickly. The likes of Emma Sleep and Nectar Sleep prove that a good mattress needn’t cost the earth, so you have more options available to you now than you may have first thought. Usually, mattress prices are at their lowest late November, making Black Friday mattress deals to upgrade for much less.

How to choose the right mattress firmness

How soft or firm a mattress feels is rated from 1 to 10, with 10 being the firmest mattress possible (we rarely, if ever, see these). As mentioned earlier in this guide, a medium firmness is one of the popular choices as it hits that sweet spot between snug comfort and proper support for your entire body. 

That said, the feel of a mattress is subjective. When we test them, for example, we often experience them in different ways because members of our review team have different body weights and heights. So how do you choose the best mattress firmness for you? There are two key considerations that can help you figure this out…

1. Your body weight
Generally speaking, if you have a body weight of 130lbs or less, you will feel comfier on a softer mattress (rated 2-4), especially if you are a lighter weight side sleeper. A softer innerspring or memory foam bed is a good choice here, as it will provide all the cushioning you need around your back, hips, knees and shoulders. But if you enjoy the feel of a medium firm mattress, then anything rated up to a 5 should also suit you. 

If you weigh 130lbs to 230lbs, a medium or medium-firm mattress (rated 5-7) will provide the full-body support and spinal alignment you need for a healthy sleep posture, without feeling too hard and uncomfortable. Pick a medium or medium-firm memory foam mattress if you want a cradling effect on your body during sleep, or a medium to medium-firm hybrid if you want a slightly firmer feel and a more breathable mattress. 

For people weighing over 230lbs, especially if you co-share your bed with another person weighing over that amount, pick a medium-firm mattress (7 out of 10). That level of firmness will ensure you sleep on top of the mattress, rather than sinking into it, so you will remain in alignment during sleep. If you’re experiencing back pain, a firmer mattress could be the better choice but we’d advise asking your doctor or physical therapist first.

The best mattress brands offer decent risk-free trial periods, meaning you’ll have at least a few months to test out your mattress at home to make sure you’ve picked the right firmness level for you.

2. Your dominant sleeping position
This refers to the position you feel comfy enough to fall asleep in. A lot of good quality memory foam and hybrid mattresses are designed to support a wide range of common sleeping positions (back, stomach and side), but it’s still worth ensuring that your chosen mattress has the correct materials, construction and firmness to support your dominant sleep position. 

Back sleepers
If you sleep on your back, choose a medium-firm mattress as this will keep you on top of the mattress, rather than letting you sink into it. This is vital for back sleeping because you want neutral spine alignment to avoid any pain in the morning.

Stomach sleepers
Like back sleepers, you should steer clear of soft mattresses if you snooze on your front. A medium mattress is best for you, and particularly a hybrid if you sleep hot. Pick one that’s too firm or too soft and it will throw your spine out of alignment and put pressure on your back.

Side sleepers
Your main pressure points in this sleeping position are the shoulders, hips and knees, so pick a soft to medium mattress with ample cushioning to relieve pressure around those impact points. Memory foam models are very popular with side sleepers.

How to buy a mattress online: expert tips

When buying a mattress online, make sure you’re buying from a company that offers a risk-free trial period of at least 30 nights (most of our top picks are 100 nights or more). It can take your body around three weeks or longer to get used to a new mattress, so these trial periods are vital.

If you change your mind during the trial period, you can get a refund from the brand and they will collect the mattress. Some manufacturers offer free returns while others charge a fee, so read the terms before buying. We’d also recommend looking for discounts on your chosen mattress as there are usually plenty of good mattress sales to lower the overall price you’ll pay. 

Black Friday mattress deals are the best way to buy a good mattress for less, as manufacturers lower their prices in time for the holiday season shopping. So even if a mattress brand offers 35% off year-round, if they lower the actual price of their mattresses for Black Friday, that makes the mattresses cheaper overall. 

Keep the following in mind when mattress shopping, and if you're unsure which size to buy, read our guide to mattress sizes and bed dimensions:

* Make sure the mattress is designed to support your sleeping style.

* If you sleep warm, choose a mattress that’s breathable or cooling (best).

* If you share with a restless sleeper, ensure your mattress has motion isolation.

* For neck and back pain relief, choose a mattress with zoned support around your neck, shoulders and back.

* Always pick a mattress that comes on a risk-free sleep trial.

* For maximum hygiene, choose a mattress with a machine washable cover.

When is the best time to buy a new mattress?

While you can buy other types of products year-round and not see much change in terms of pricing or discounts, it’s a different ball game with mattresses. If you want the cheapest mattress prices and good sale offers, then the best time to buy a new mattress in the UK is on Black Friday, which usually falls on the last November of every year. This year it’s Friday 26 November. 

This is when we see big price drops from major sleep brands, as they are competing with one another for your holiday season custom. Our guide to the best Black Friday mattress deals contains everything you need to know to help you save the most money.

What is the best mattress in the UK?

We think the Emma Original is the UK’s best mattress as it offers brilliant value for money and a comfy spot for all sleeping positions. Yes it sleeps a little warm compared to other more breathable mattresses, but for the low price  – it’s often discounted by up to 40% – the Emma Original is fantastic value. It comes with a 10-year warranty and you’ll have 200 nights to try it out at home too. If you change your mind, Emma will refund your money and collect the mattress. 

Alternatively, if you have a slightly bigger budget and want a cooler mattress with a firmer feel, we’d recommend the Simba Hybrid Original. At 25cm it’s the same height as the Emma and offers good motion isolation, which is needed if you share your bed with a restless partner. Because it uses a mix of coils and foam, air is able to move more freely around the Simba, so you’ll naturally feel cooler during sleep.

There’s normally a new customer discount of up to 41% on Simbas too, so if you’re buying from the brand for the first time, you can make a brilliant saving on your new mattress.

Which is the best type of mattress?

There is no one mattress type to rule them all. Instead, the best type of mattress for you depends upon a few key factors including your body weight and whether you have any specific health or posture needs (for example, you have night sweats or frequent back pain). 

Your bed buddy should be taken into account too. Finding the perfect mattress as a couple is easier these days because more UK mattress manufacturers are making customisable models. Dormeo, for example, makes a mattress that has two different levels of firmness, and both of these can be rotated to better suit your posture needs. 

When buying a new mattress, you’ll come across these four main types:

Memory foam
A fantastic choice for anyone who likes to feel hugged during sleep. All-foam mattresses are comforting and cosy, but basic foams can sleep warm (they retain heat). The exceptions are breathable or open-pored foam materials as used on the Nectar Memory Foam Mattress and the Emma Original. Read our dedicated guide to the best memory foam mattresses to learn more.

Hybrid mattresses
Hybrids are the present and future of mattress technology. You’ll find the most innovative materials within hybrid mattresses, which is one reason why they are more expensive than foam models. They are more breathable by design (in addition to foam they use coils or springs, around which air moves more freely), making them a good mattress type for warm sleepers. You may be surprised at how firm they feel compared to a foam mattress though, so keep this in mind if you enjoy softer beds for sleeping.

Innerspring mattresses
These use coils (interconnected or pocket spring) to offer more bounce than foam models, and they aren’t quite as firm as hybrids. The more springs your mattress has, the more support it gives. Innerspring mattresses are also a good choice for hot sleepers as, again, air moves more freely through them. They can feel a little firm to begin with, so consider adding one of the best mattress toppers to increase your comfort.

Latex mattresses
A good choice for people who want a more natural mattress with lower levels of toxins. Latex is cooling, durable and long-lasting, giving you good sleep comfort and value for money over the long-term. That also means latex mattresses are usually more expensive than mattresses made using synthetic materials.
