Emma

Emma is an immensely popular British manufacturer who specialises in bed in a box mattresses. First clamouring to fame in 2015 but achieving real velocity from 2018 onwards, Emma is one of the last standing in the war on sleep having bested Eve, Casper and Leesa, all of whom had similar marketing objectives and business models. To date, Emma offers 2 mattresses commercially through their own website with store and retailer derived versions for the masses of retailers looking to piggyback the brand's success. The mattresses all feature foam as a staple with some featuring additional springs. Regardless of which version you choose, comfort is almost guaranteed with thousands of satisfied customers to date.

Recently Emma rebranded to become known as Emma Sleep and pivoted their focus toward other items in the bedding sector ranging from bed frames, pillows, duvets and protectors.

Coolflex

Coolflex is a value hybrid mattress range sold exclusively through MattressNextDay. The brand has grown from a single rolled mattress into a catalogue covering multiple construction types with a specific focus on cooling technology at accessible pricing. The range includes the Essentials Pocket Memory Hybrid, Premium Memory Hybrid, Hybrid Ice, Hybrid Chill and Lux Ortho Pocket, each targeting a different buyer profile.

What makes Coolflex worth looking at is the combination of proper pocket spring hybrid construction with cooling-focused materials at prices that undercut the major direct-to-consumer brands. For hot sleepers shopping on a budget, Coolflex is one of the first alternatives to consider.

Emma Owner Satisfaction

Emma Sleep’s entire business model is focussed toward consumer satisfaction. Key parts of their marketing strategy comes from word of mouth and statistics show that people buy from people. What makes Emma stand out from the crowd is an interesting shift in consumer buying behaviour. Previously, if you bought a mattress and didn’t enjoy it, you were out of luck, not so with the rise of Emma. Now, if you don’t like your mattress you can simply arrange a return and get a full refund within the first 100 days. This shift has proved extremely positive for customers and has increased satisfaction in the lineup.

To date, Emma has amassed an impressive 22,000+ reviews on Trustpilot, a fantastic display given the company's fairly new tenure in the industry.

Emma Supportiveness

Firmness is a very subjective thing which proves a particularly tough nut to crack when you are producing one mattress to suit all people. So much so that Emma has prototyped and tested numerous models previous to going to market in order to get that mix just right. The result? Right now Emma has two mattresses, a medium tension and a medium firm tension. Medium is a great supportive rating as it gives the user enough body contouring and support in the back and neck while giving enough softness and compression to accommodate those who sleep on their side or are of a lower BMI. It really is considered the one-size-fits-all approach and it’s one that suits many who purchase an Emma mattress, just take a look at the thousands of reviews to date.

Emma Durability

With the mid-range price point of Emma products, it’s important for shoppers that the bed lasts for a number of years. Generally we find companies consistently trying to cut costs at the expense of durability. Fortunately Emma already has a unique business model as the mattresses follow the rolled and bed-in-a-box model that allows savings through logistics and delivery meaning Emma can spend more on materials while still finding profit. The result of this means you get a mattress that is affordable and of higher quality than competing brands which, as a result of the quality increase, is more durable and lasts longer as a result. It’s a win for everyone.

Coolflex Owner Satisfaction

Coolflex reviews are consistently strong on two specific points: the cooling performance is real rather than marketing decoration, and the value for money at this price tier is hard to beat from the mainstream alternatives. MattressNextDay handles delivery and returns reliably, which gives the buying experience a stable foundation that standalone budget brands often lack.

Hot sleepers are the buyer profile most likely to rate Coolflex highest, because the cooling technology in the Hybrid Ice and Hybrid Chill models delivers a measurable difference from standard foam alternatives. The main complaint pattern we see relates to edge support on the entry-tier models, which improves as you step up through the range.

Coolflex Supportiveness

The pocket spring cores across the Coolflex hybrid range provide genuine structural support that pure foam alternatives at similar prices typically lack. The Premium Memory Hybrid is the sweet spot for most buyers, with a spring count and foam layer depth that handles average weight sleepers across back and side positions comfortably. The Lux Ortho Pocket handles the firmer end for stomach sleepers and back pain sufferers.

The Hybrid Ice and Hybrid Chill add cooling layers on top of the pocket spring base and are the models to look at specifically for hot sleepers who want temperature regulation alongside the hybrid support structure.

Coolflex Durability

The pocket spring and foam hybrid construction that Coolflex uses across the range is the build type we generally expect to last longest at this price tier. Pocket springs provide structural longevity that all-foam alternatives cannot match, and the foam layers above use reasonable densities for the price point. MattressNextDay backing gives the brand a retail infrastructure that supports warranty claims.

As a newer brand, the long-term durability data is limited compared with heritage manufacturers like Silentnight or Sealy, but the construction approach is sound and the early-year review data is consistent with what you would expect from a well-made hybrid at this price.

After purchase and having a nightmare with a different boxed mattress from a very well-known brand, I was really sceptical about all the positive reviews for this but really wanted to see if they were all the same.
I need not have feared. This is simply brilliant.
Excellent delivery from 2 John Lewis drivers who both wore masks and asked me to keep my lounge door closed. They called to say they were on their way so I had everything ready.
Yes the mattress needed airing for a few hours and what u found was that if you remove the top cover this helps the foam breathe. I washed the cover twice straight after each other and left the mattress overght with the window wide open in the bedroom.
The results were that within a few days the smell had completely gone and nothing was lingering. Yes put your nose to it and you could still smell bits but nothing like the other I had which smelt toxic.
The comfort is fantastic. If you sit on it you sink, especially perched on the edge but once laid flat on it your body is well supported with no bottom sag in the middle that I had from the previous one.
A few months in and I have to say this is the best mattress I have ever had. No dips, easy to change due to handles close to the 4 corners and very light.
The zipped top is great for removing and washing if needed.
John Lewis you have restored my faith in boxed mattresses after a terrible experience with another brand.
Stick with this one and you wont go wrong.
I use 2 firm down pillows with it and due to the softness of the mattress they have eased more giving a medium to firm response. With my previous mattress these pillows were far too hard so you may need to play with some pillows as they will feel different.

I am soooooo glad that I bought this just before the Black Friday when it came back into stock. This bed is so comfortable! I have never had a memory foam mattress, only a mattress with springs. It sound strange but I cant believe how quiet it is! When my boyfriend moves around, I cant hear or feel anything! The mattress is currently on the floor as my new bed frame has not arrived yet and its still very comfortable. Its not too firm. I would definitely say its medium. I am thinking about getting the firm topper which is free. But will decide once frame arrives. The mattress is a lot lighter than my previous mattress which makes changing the sheet easier. And the delivery service was excellent. I received a text message with my 4 hour time slot. And it arrived exactly at the beginning of the slot. I was running late and the driver called me and waited for me. He even took it up two flights of steep stairs. All the Way to my flat. There is a slight chemical smell. Its been two weeks and sometimes I do get a hint of it under the sheets. But I wouldnt say its terrible or very noticeable. And would probably disappear faster if I aired the mattress out a bit. There are only two downsides for me. Number one, the handles on the side arent very strong. Number two, I never want to get out of bed in the morning, so Im nearly late for work every day!

We had been waiting to get a new mattress from before lockdown, but wanted to go to the storeroom of a well known manufacturer but hadnt found the time. After some research and reading reviews decided to take a chance on this mattress rather than just keep waiting for said showroom to re-open, and are we glad we did. This mattress is wonderfully comfortable and a fraction of the price we were considering spending on the other mattress. With the price, the option to return if not happy and the 10 year guarantee you really cannot go wrong with this mattress. It is also considerably lighter than the one we were considering - a consideration as you get older, particularly in these strange times when you might only get something delivered to the door. My wife is sensitive to temperature at night and we have slept (or tried to sleep) on mattresses that seem to generate heat, and this was a concern with a mattress that included memory foam, but there has been no issue from that perspective. Others have commented on the smell of the mattress, but having left the mattress to "settle" and air for 24 hours, we didnt find this to be an issue. All in all delighted with this purchase and would recommend to others - so much so that we bought a second for the guest bedroom.

I was a little dubious at the beginning about this product because of reviews online and had to think before I purchased it but after a week I decided to just buy it as it comes with a sleep trial so its risk free (200 night trial)
The mattress is top quality, was surprised at how easy it is to unpack and get ready on the bed. After about 3-4 hours it was in its full size and ready to sleep. The best thing to do is leave the window opened so room is well ventilated as it has a new sort of smell at the beginning, I would say this lasts about 48 hours but can be longer.
The easiest way to allow this mattress to expand is to remove the top cover and let it breathe (tip that Emma gave me when I emailed them). The first time I used it I felt so weird sleeping on it (in a good way), it was so comfortable! It just goes to show how bad an old mattress is. I find it a little soft for me however you can receive a comfort layer (request these and Emma will send it free of charge) which can improve it and make it firmer and also add 14 days to the trial!
Has it made a difference to my sleep? Yes!
Would I recommend it? Yes!
Would I buy another? Yes!
Do I want to get out of bed in the morning? No

This is a fantastic mattress and extremely comfortable. Having bought a different out of the box mattress that seems to be on the TV all the time, I was really apprehensive about getting another as the first one was great for the first few months but then sagged in the middle and the springs became faulty. John Lewis were brilliant however and refunded me.
So onto this one - delivery was fantastic as always and contactless as I stayed downstairs.
The mattress is easy to turn around due to the 4 handles - 2 on each side which is a bonus. The quality is outstanding and the top cover is easy to remove and wash.
There was a slight smell for a couple of weeks but I regularly removed the cover to air the foam for a few hours and washed the cover so it smelt of my washing powder. This has now completely gone.
The firmness did take a while to get used to. I had a cheap firm mattress from a famous swedish store so this felt soft but after a few nights sleep, this wasnt an issue. I now sleep soundly.
Really pleased with this and with the 200 day trial and no quibble return - I feel very assured that this could finally be the one for me.
Highly recommended.

Very glad I didn't spend 900 on a mattress (as I was going to!), As this one is absolutely perfect and didn't break the bank (hurray!) Its soft on top, but firm and supportive... My partner and I do not roll into each other in the night as pre my previous mattress. We both sleep really soundly on this mattress which suprises me as he actually prefers really really firm memory firm mattresses that feel like concrete!! Doesnt give me back pains like my previous mattress, wake up refreshed. Something I was worried about for the low price tag! The edges are not reinforced so do sag if you sit on the edge of the bed - but its fine when you are asleep//roll onto the edge - ie, you dont end up falling off as with some mattress that are not reinforced!. It does get a bit hot with the memory foam, but after putting a bottom sheet on, it isnt as bad as it was on the first couple of nights.

4 Jillian Knight

Very good quality mattress! great support throughout and good degree of comfort. Mattress came rolled up so needed approx 24 hours to properly settle and for all the creases to disappear before I could use this. This time for the mattress to fully open was stated in the delivery note so I was not concerned about the wait. The only issue I noticed was the mattress is fairly heavy to move due to the number of springs inside, and there are no carrying handles on the sides that would have helped to assist with moving and positioning the mattress. Otherwise I am very happy with this product.

5 Eileen Smith

When I ordered 'next day delivery', I was sceptical. I need not have been. I received an email advising a next day delivery slot of 9.40 - 11.40 and the mattress was delivered at 11.15. The delivery guys were lovely carried it up to the bedroom. It was a great service. I only wish you did next day delivery black 5 drawer chest of drawers, as I have been badly let down by littlewoods and they had up to 15 days to deliver. Let me down badly and so I cancelled. I would recommend your company to friends and family. Thank you.

4 Nik Pringle

You need to ensure you have the mattress the right way up - indifferent nights sleep until I spotted it was upside down! getting used to it after a couple of nights, the edges of the bed are not as firm as our previous sprung one making it slightly uncomfortable to sit on the edge. There is also a tendency to roll together into the middle - hence 4 * as opposed to the full 5. I tend to find memory foam mattresses sleep "hotter" than normal ones - fine at the moment but may be a bit warm if we get a good summer.

5 Dawn

I was actually surprised with the quality and comfort of this mattress considering its very reasonable price. It was delivered rolled in several layers of polythene, which was necessary to contain it. It is a lovely deep mattress and so comfortable. I would recommend it to anyone, and am positive it has to be as good as any mattress considerably more expensive. Id been prone to back and hip aching problems on a mattress that wasnt right, this mattress solved that after first night.
