Emma ‘bed in a box’ mattress review

We’ve been testing out ‘bed in a box’ style mattresses during our sleep feature, and our next product for review is the Emma mattress.

Emma is similar in some ways to the Casper we reviewed only recently. In fact, with the white top, grey sides and blue label, it looks pretty damn familiar, but don’t be fooled – while the Casper is 100% foam, Emma is a hybrid.

Yes, Emma is the Toyota Prius of the mattress world, combing pocket springs with foam. So, how does she fair? Read our review to find out.

Let’s first take a look at what the Emma mattress offers, before going into the full review.

The Emma combines three layers of foam, with 2,000 individual pocket springs. The theory is that the springs will optimise the support your body needs; delivering it where required, letting off where not.

The three layers of foam include Airgocell® foam, which, like springs, reacts in different areas, adapting to your body, and also providing breathability, so you don’t wake in a sweat. Visco-elastic memory foam makes up the layer beneath the springs, and supportive foam makes the base. Interestingly, the base foam is cut to continue providing different support for specific areas of the body.

The key selling point for the Emma is its ability to adapt. Throughout the layers, there is the ability to serve different areas with different levels of support. The folks behind Emma claim this prevents the mattress from being too soft or too firm.

So is Emma the Goldilocks of the mattress world? Let’s find out.


I’m reviewing the king size mattress, as with all of the mattress reviews on Pixel Health, and the Emma costs £679 for this size, inclusive of delivery. This is a rather good price, and works out at £69 per year, considering their 10-year guarantee. For a good night’s sleep, it’s worth it.

Of course, there are cheaper mattresses, but there are more expensive ones too. Looking at the usual prices for bed in a box style mattresses, the Emma is on the reasonable end of the scale.

For those wanting a double, you’re looking at £599 and if you’ve got a large room to fill, the kingsize is £799. If you’re unlucky enough to sleep in a single bed, then £399 is all you’ll need to shell out – but we’d suggest spending your money on a double bed first!


You may have noticed in the Casper review that the state of the box was one of our few criticisms. It was rather battered, but I’m starting to learn that all bed in a box mattresses will come in a damaged box, and Emma is no different.

The damage was certainly less so than the Casper, and the mattress was completely unaffected. The thing is, these mattresses are heavy, so the box is expected to be a little tattered.

The Emma arrived super fast, within 2 days, and delivery was via UPS, meaning you can track it along the way. I was over 100 miles away from home the day it arrived, so the tracking was extremely useful, and thankfully I made it back home just as the UPS van was pulling up to my drive.


Here’s what you really came for. Is the Emma mattress comfy? Is she really the best mattress in the UK as their reviews claim? Let’s find out.

The Emma was pretty easy to get onto the bed, and even within 5 minutes, she looked nice and plump. I waited until the evening to try her out. But, boy, was it worth the wait. The Emma is extremely comfy – soft where it needs to be, firm where it needs to be. It feels as though the Emma mattress is adapting to your body as if there were a smart chip inside letting it know how to react.

Of course, it’s not a chip, but the combination of springs and foam. Their claim of ability to adapt – the Goldilocks of the mattress world – certainly holds true. They talk the talk and walk the walk.

With all mattress reviews on Pixel Health, we try them out for at least 2 weeks. In fact, I went a week further, since I enjoyed the Emma so much. The comfort continued, and sleep was, well… forgetful. I’d fall asleep, and wake up almost immediately after. Seven hours would have passed and I’d feel completely refreshed, with no aches or pains.


The Emma mattress has no real downsides. With comfort on her side, adapting to your body and movement. It even has holding handles, which makes it easy to move onto the bed – something that is often missed with bed in a box style mattresses.

According to their website, the Emma is the UK’s best mattress. And while we have much more to test at Pixel Health, we feel the claim stands true. It’s well worth a try.

Comfort is king, so it makes up 80% of the total score.

    I recently purchased the Emma mattress as it was the Which? best buy awarded mattress for the year 2017 and after reading the good reviews over Pixel Health. It has been a wonderful experience with the mattress so far. The Emma is super easy to set up, keeps cool at night, and is so soft you don’t even need a sheet if you don’t want it. There is a slight odor to the bed when it is first set up, but with open windows and no sheet on, the smell was gone in a day or two. Now it’s just beautiful nights of restful sleep for me on a bed with perfect firmness and hardly any movement transfer. Love this bed!

      Hi Jessica. Yes, there are handles. I took a look at the images on their review and I think the angles just don’t show them. Unless they have changed the design since my review, there are handles (which is very useful!)

    I have purchased one of these in a king size and am expecting the delivery today. If the service offered by the company and in particular a gentleman called Justin, who deals with strategic planning, is anything to go on, I’m expecting nothing but bad things! I hope I’m wrong and the mattress is everything I hope it will be but the service during the purchase procedure has been truly appalling….. so far the delivery has taken 2 weeks!

    • David Clare

      Hi Mark. The service we experienced was excellent, so it’s a shame to hear that. However, the mattress is great, so we’re sure you will enjoy it. Please do comment again with your experience.

      Could you please try and measure the actual width of your king size mattress and advise? I have asked this question on the Pixel Health website and explained why.
      Thanks, Anthony

    Could any owner of an Emma king size please advise the actual measured width of the mattress?
    I am really interested to buy this mattress but do not expect to have a side gap between the mattress and my lovely bed frame.

    Emma, like all of the mail order mattress provide dimensions in metric, but is the figure they quote a metric equivalent to 5 feet or is it actually 150cm? Note 150cm is 4’11”, that is 1″ short of the standard UK king size width.
    The accepted standard UK king size mattress is 5’ x 6’6”, note imperial measurements since the UK was historically non-metric. An accurate metric conversion is 152.4cm x 198.1cm, however this is not easy to remember or say, so approximate figures of 150 x 200cm was adopted. Note however the term ‘150x200cm’ is an approximation and was used to refer to the UK standard of 5’ x 6’6”. So when a ‘Emma’ state their mattress is 150×200 and a UK standard size, it should therefore follow that the size is actually (5’ x 6’6” or 152.4cm x 198.1cm). Owner measurement requested, please!

    Honestly, I wouldn’t bother ordering from this company.

    Their website says delivery within 5-7 days. By the admission of their own staff, they have never been able to meet his so essentially blatantly lie to customers on their site.

    The ‘customer services’ line is neither use nor ornament – they simply blame everything on ‘IT problems’ and aren’t able to come up with a solution.

    I’ve given them until 3pm tomorrow for a shipping confirmation after this point I’ll be cancelling my order.

    • Jon

      Hi Matt, can you update re the above please ? I’m in a similar position, a 6week wait so far and unable to offer expected delivery date. Considering cancelling and trying Leesa instead.

    hi david how firm was this? i am returning the Simba as it is much too soft for me, and I’m looking for a replacement. which from all the ‘out the box’ companies would you suggest is the firmest?
    many thanks

    • David Clare

      I haven’t tried the Simba yet, however the Emma is pretty firm, so worth a try. Plus, you get the 100-day trial, so no risk.

    Can you put a Emma Mattress on a slatted bed !
    The bed we have is new and the slats are approx 7-8cm distance between.
    Really impressed by write ups of Emma re back problems but need to know if it will fit our new bed.

  7. Rebecca

    Been waiting 5 weeks for the Emma mattress to arrive still no sign and customer service haven’t got a clue when it will be delivered however the finance company want me to pay for the item even though I’ve not received it what a joke!!!
