Why buy a mattress in a box, rather than trawl on down to the shops at the weekend, try one out and order there? Well, if you choose your mattress online from one of the many 'bed in a box' companies, it will arrive in days (rolled up in a box), ready to be unwrapped and used in just a few hours. Then, you have (usually) 100 days to decide if it's the mattress for you. If not, you can get a full refund.

Now, buying a mattress online might be something you're nervous of, but if you're looking to find the best mattress for your needs, don't miss our deep mattress reviews which will give you a very firm idea of whether the mattresses we're talking about are for you. 

We're happy to recommend all these best mattresses in a box – dive in and find one that's right for you.

Casper Premium Memory Foam Rolled Mattress

1. Casper Premium Memory Foam Rolled Mattress: Best for zoned support

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

Specifications
Size: Single to Super king
Depth: 24cm
Type: : Memory foam/comfort 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. Otty Hybrid: Best for every man, woman and child across the land

We’ve got a lot of love for this modern memory foam mash-up

Specifications
Size: Single to Emperor
Depth: 25cm
Type: Hybrid Foam/Spring
Comfort grade: Medium to Firm
Reasons to buy
+Quality springs give decent support+The whole surface is equally comfy
Reasons to avoid
-None

Who will the Otty Hybrid mattress suit?

Cool customers seeking a non-sweaty night’s sleep + space-hogging couples. 

What is the Otty Hybrid mattress like to sleep on?

This is one of the cheapest ‘branded’ bed-in-a-box mattresses out but never is this fact reflected in the quality feel or sleep experience. More robust than many memory foams, the lengthy springs provide just the right levels of bounce and support – it’s not too soft, nor too hard. That would be perfect then. Except there is a small amount of motion transfer but certainly not as much as you’d get from a full-on pocket sprung and nothing to really blot its copy book. 

Special features?

The cooling technology inside this beast is the stuff of legends – no exaggeration. Night sweats = a distant memory. The cover is removable and washable – hzar!

Fillings?

As you might predict, a layer of Cool Blue Gel memory foam keeps you cool (and it works), and a layer of reflex foam brings support. The 14cm tall pocket springs are where this mattress stands out from the other hybrid mattresses, who tend to go for short or conical springs. Then there’s the requisite solid foam base that protects it from your bed base and generally prevents sinking. 

What do you get for your money?

A 100-night trial, 10-year guarantee and free delivery. 

Emma mattress

3. Emma Original mattress: best for anyone seeking medium firm support

Designed to suit all manner of body shapes, weights and sleeping positions, the Emma mattress is a good all-rounder

Specifications
Size: Single to Super king
Depth: 25cm
Type: : Comfort foam/memory foam
Comfort grade: Medium
Reasons to buy
+ Zoned support and temperature control
Reasons to avoid
-If foam is just not your thing

Who will the Emma mattress suit?

Anyone seeking memory foam and medium-firm support.

What is the Emma mattress like to sleep on?

Once unrolled, the Emma quickly expands up to its 25cm height. The instructions specify ‘only a few hours’, which is a bit vague – ours was ready to sleep on within two hours. And, glory be, it did not smell. Big tick. Night one (and two, three, four and five for that matter) went without a hitch. We tested it during a fairly muggy week in August, not heat-wave material but still pretty warm; one of the first things I noticed was how coolly I slept. Motion transfer was next to non-existent and, it was also easy to move around on the Emma. No getting wedged in one position here. This was almost certainly down to the layers of foam, but also because we are in agreement that Emma is a fairly firm lady. 

Special features?

The base layer, dubbed the ‘Supportive Cold Foam’, is where the Emma Original is a little, well, more original than the other memory foams in this class. Thanks to specially located grooves in the foam, support is zoned for optimum weight distribution. I tried sleeping on my side, back, and front and can honestly say I felt well supported in each position. 

Fillings?

The Emma Original sports three layers of foam, beneath a breathable, removable top cover (that can be washed at 60 degrees). The top layer is an elastic foam they call Airgocell, which allows one area to compress without effecting the rest of the mattress. T basically means this is the bit that gives you a little softness and bounce. 

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.

Simba Hybrid Mattress

4. Simba Hybrid Mattress

An excellent all-rounder for your bedroom or spare room: Best for everyone

Specifications
Size: Single to Super king
Depth: 25cm
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.

Leesa Premium Foam Mattress

5. Leesa Premium Foam Mattress: Best for temperature regulation

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

Specifications
Size: Single to 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.
