1. The Casper Mattress

This award-winning dual foam mattress scores big on comfort and coolness

Specifications
Best for: Zoned support
Size: Single-Super-king
Depth: 24cm
Type: Comfort foam/memory foam
Comfort grade: Medium
Reasons to buy
+Cool, comfy foam+Brilliant customer service
Reasons to avoid
-Usual chemical smell, but it will fade

What is the Casper like to sleep on?

Casper is softer than some memory foams on the market, making it perfect for side sleepers. Your hips and shoulders sink lower than the rest of your torso, providing an ergonomically aligned spine. There’s precious little motion transfer so you won’t notice your partner thrashing about in the small hours. The cooling layers also make it breathable, which again aids undisturbed sleep. Which? has given it five stars for comfort and support, while the majority of Amazon’s reviewers are thrilled with their Casper, revealing that they wake up feeling fresh and revived.  

Special features?

The top cover zips off for easy cleaning (at 40 degrees in your washing machine, thankfully) and there are handles for easy manoeuvrability – you’ll be amazed how many mattresses don’t have this simple but extremely useful feature. It comes in eight sizes, including EU (which are a tad longer than UK), so you’re bound to find one to suit. There’s even a Casper bed for your dog!

Fillings?

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

What do you get for your money?

A 10-year warranty, free delivery and returns, plus very good customer service, according to the reviews. Look out for discount codes on the Casper website and social media – typically around 15 per cent.

2. Rest Assured Richborough Pocket Latex

Size: Double-Super-king
Depth: 30cm
Type: Pocket spring/latex
Comfort grade: Medium
Reasons to buy
+Luxury feel+Allergy-friendly+Handmade in the UK
Reasons to avoid
-Heavy + high (fortunately it's 'no-turn')

Who will the Richborough mattress suit?

Anyone seeking a really luxurious pocket spring mattress 

What is the Richborough mattress like to sleep on?

This mattress falls on the firmer side of medium, but still offers a good level of cosy comfort thanks to its latex topper. It offers decent support for shoulders and hips, which is great news for side and back-sleepers, and we also found motion transfer was minimal – ie, your partner won’t disturb you during the night. Build quality is unprecedented, and this shines through when you sit on the edge and it stays strong and supportive. Speaking of which, it is a deep mattress, which could prove an issue if you already have a tall divan base.  

Special features?

Treated with Purotex, a textile additive that uses good bacteria to stop dust mites and other household allergens from multiplying. Allergy UK approved. Single-side, so no need to flip but it does require rotation. Also comes in soft and firm versions. 

Fillings?

A pocket spring base (2,000 in a King size), with a latex filled pillowtop for extra comfort.

What do you get for your money?

A five-year guarantee. Delivery is an extra £14.99.

Specifications
Best for: Back sleepers
Size: Single-emperor
Depth: 24cm
Type: Comfort foam/memory foam
Comfort grade: Medium-firm
Reasons to buy
+Breathable foam+100-night trial
Reasons to avoid

Who will the Eve mattress suit?

Aimed at the masses, this is a one-size-fits-all sleeping solution (though we found it most comfortable on our backs)

What is the Eve mattress like to sleep on?

Once you have got your head around the bounce-less solidity of memory foam (which takes a couple of nights), the Eve mattress will treat you to really decent, undisturbed sleep. Ranging on the firmer side of medium, maybe even forget the word medium completely, the Eve is particularly popular with those who like to sleep on top of their mattress, rather than in it. Online reviews suggest you will have ‘the Best Sleep Ever’, and while we might not go quite that far, the Eve definitely out-performs some of the other bed-in-a-box memory foams we have tried. 

Special features?

The top cover, which zips off for washing, is made from moisture-wicking fabric for a cool night’s sleep. 

Fillings?

From the top; a 3.5cm thick open-cell hybrid foam offers maximum breathability, then there’s a 3cm layer of memory foam for contoured support, and a 17.5cm thick base layer, again foam, that’s sliced into zones to target key body areas. 

What do you get for your money?

A 10-year guarantee, free delivery and free, no-fuss returns after 100 days.

4. Leesa

A luxuriously thick layer of memory foam will soon have you sleeping like a baby

Specifications
Best for: Temperature regulation
Size: Single-Super king
Depth: 25cm
Type: Comfort foam/ memory foam
Comfort grade: Medium
Reasons to buy
+Perfectly pitched comfort at a fair price
Reasons to avoid
-Sponge-clean only

Who will the Leesa mattress suit?

Risk-adverse shoppers looking for a safe bet that they’ll sleep soundly.

What is the Leesa mattress like to sleep on?

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

Special features?

We love Leesa’s ethical values, which include planting a tree for every mattress sold. On a more materialistic note, the grey striped cover is pretty cute.

Fillings?

Three foam layers – a 5cm thick Avena foam, which is a latex-like comfort foam, a 5cm thick memory foam for weightlessness, and a 15cm thick base foam for overall support. 

What do you get for your money?

A 100-night, no-risk sleep trial, free delivery and returns, 10-year limited warranty and cash back (£30) if you refer a friend.

5. Emma

Which? waxes lyrical about this fine foam mattress – and we completely agree

Specifications
Best for: Ease of movement
Size: Single-Super king
Depth: 25cm
Type: Comfort foam/ memory foam
Comfort grade: Medium-firm
Reasons to buy
+Zoned support+Perfect temperature control
Reasons to avoid
-None

Who will the Emma suit?

Anyone who is signed up memory foam fan.

What is the Emma like to sleep on?

There pretty much nothing we don’t like about this mattress. It’s easy to switch positions, and comfortable in whichever position you favour for that matter. We’d rate it towards the firmer end of medium, but it’s certainly not rock solid. The mattress is evenly supportive across the entire surface, so there’s plenty of room to spread out. Which? has awarded the Emma Original its coveted Best Buy this year, placing it at the top of its mattress comparison table no less.

Special features?

The breathable, removable top cover can be washed at 60 degrees, which is going to bust dirt better than the standard 40 degrees. Handles make it easier to manoeuvre.

Fillings?

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

What do you get for your money?

A 100-night sleep trial, no questions asked, 10-year warranty and free delivery, usually within one to three working days.

Multiple firmness options make this innovative new mattress your flexible friend

Specifications
Best for: Flexible comfort
Size: Single-Super king
Depth: 20cm
Type: Comfort foam/ memory foam
Comfort grade: Multiple
Reasons to buy
+Customisable comfort suits different bodies+15-year warranty
Reasons to avoid
-Bit of a faff to flip mattresses about

Who will the S Plus suit?

Couples who don’t share firmness preferences.

What's the S Plus like to sleep on?

This mattress offers four comfort option: firm with shoulder support; firm with hip support; soft with shoulder support; and soft with hip support. Additionally, it splits in two within the cover, so each partner can find their dream firmness. We tried all the permutations, and although the soft side wasn’t as soft as it could have been, we found our perfect match. Rather cleverly, and don’t ask us how they’ve done it, our posture tests revealed perfect spine alignment in every comfort option. In short, your joints won’t be put under pressure no matter which way the mattress is flipped. 

Special features?

Besides all this flexibility and choice, the S Plus offers great temperature control thanks, in part, to its Climalite cover that wicks away moisture. 

Fillings?

Two layers of Ecocell foam, one soft, one firm, sandwich a foam spring core. The giant S-Shape created provides the differing firmness levels for shoulders and hips.  

What do you get for your money?

A 60-night sleep trial (refund or exchange), 15-year warranty, free delivery. And a free Octasense pillow when you buy direct from Dormeo.

7. Silentnight Mirapocket Eco Comfort Breathe 2000

This unassuming new pocket sprung number punches way above its weight

Specifications
Best for: Eco credibility
Size: Single-Super king
Depth: 31cm
Type: Pocket spring
Comfort grade: Medium/firm
Reasons to buy
+Eco-friendly+Temperature regulating
Reasons to avoid
-Unimpressive guarantee

Who will the Eco Comfort Breathe 2000 suit?

Pocket spring devotees that care about our planet.

What is the Eco Comfort Breathe 2000 like to sleep on?

There’s no memory foam top, latex layer, or billowing pillow topper but the Eco Comfort Breathe 2000 still offers a good level of responsiveness when you get horizontal. By which we mean, your body contours into the mattress rather than sits rigid on its surface. We tested the ‘Firmer’ version, which proved exactly that, but there’s also a ‘Softer’ and ‘Medium’ option in the Eco Comfort Breathe 2000 collection. This mattress is excellent at temperature regulation, so you’ll never wake up due to heat, even if we are jammy enough to get another scorchio summer.

Special features?

Yup, 150 recyclable bottles go into every mattress. The sides feature a mesh strip to keep the inner materials freshly aerated. It’s no-flip but does require rotating.

Fillings?

Beneath three comfort layers, focused on responsiveness and air movement, lies 2000 pocket springs, all cleverly zoned to provide extra support at the hips and shoulders. 

What do you get for your money?

Five-year warranty, 60-night sleep exchange, free delivery to a room of your choice and packaging removed.

8. Simba Hybrid

An excellent all-rounder for your bedroom or spare room

Specifications
Best for: Everyone
Size: Small single-Emperor
Depth: 25cm
Type: Memory foam/micro pocket springs
Comfort grade: Medium
Reasons to buy
+Bouncy bounciness
Reasons to avoid
-Only the top cover, not sides, can be machine-washed

Who will the Simba Hybrid suit?

Anyone looking for a bit more movement from their memory foam.

What is the Simba Hybrid like to sleep on?

In a nutshell, the thin layer of tiny conical springs makes this predominantly foam mattress feel more like a traditional pocket spring mattress. It is responsive and moulds to your body, while also offering decent levels of support. Designed to accommodate all types of sleeping styles – back, front or side – there is no ‘wrong’ way to catch some zzzzzs on the Simba Hybrid. Review-wise, there are multiple tales of miraculously pain-free sleep from poor souls previously in back-related agony (including the Ed-in-Chief of RealHomes.com). So, with the 100-night trial in mind, anyone suffering has nothing to lose from giving this mattress a bash (and potentially hundreds of pounds to save at the chiropractors). 

Special features?

The cover is hypoallergenic with integral airflow for cool temperature regulation. Simba has also developed its own latex-like layer, called Simbatex, which contains cooling soybean balms. Basically it’s cool all round. 

Fillings?

From the top: the Simbatex layer provides initial comfort, then there’s the aforementioned layer of conical springs (2,500 in a king size), which brings on the bounce. Next is a layer of visco-elastic memory foam for body contouring and weightlessness. And of course there’s a fairly solid foam base, which has been sliced in seven sections to provide differing density levels, essentially targeting the support where you need it.  

What do you get for your money?

Free delivery, 100-day free trial, plus a 10-year guarantee and hassle-free returns, and a knife for opening the heavy-duty plastic bag it’s suctioned into. They’ll also whisk your old mattress away.
