Only Eve has enough owner reviews to score, so there is no head-to-head verdict here.

Head to head

Eve has 7 of its 11 mattresses sprung and 4 all memory foam; Ergoflex has all foam, with no springs anywhere in the range. Only Eve offers latex, in 1 model. Eve runs from soft to firm, and every Ergoflex mattress is medium-firm. Eve covers more of the firmness scale, which helps if two sleepers need different feels. Ergoflex is the cheaper way in, though not by much. At the top end Eve goes further still. Ergoflex doesn't have enough owner reviews with us yet to score fairly.

Eve

Eve Sleep emerged in 2014 as a prominent online retailer specialising in mattresses and sleep accessories. The company gained recognition for its clever approach to mattress design and marketing, offering a range of products aimed at improving sleep quality. In 2022, Eve Sleep was acquired by Bensons for Beds, further solidifying its position in the sleep products market.

Eve Sleep's product lineup includes various mattress types, such as memory foam and hybrid models, catering to diverse sleep preferences. In particular, the company introduced the "Wunderflip" mattress, designed to offer two levels of firmness by simply flipping it over, allowing users to customise their sleep experience.  Eve Sleep provides a 200-night trial period, enabling customers to thoroughly test their mattresses.

Ergoflex

Ergoflex entered the UK in 2006 and is one of the original bed-in-a-box brands, predating Emma, Simba and Nectar by nearly a decade. The brand has stayed true to a single-product philosophy throughout, with the Ergoflex 5G being the current and only mattress in the range. It is a deep, five-layer all-foam mattress measuring about 23 cm, built entirely from Ergoflex's own in-house manufactured foams and wrapped in a removable TENCEL cover.

The single-product approach is deliberate. Rather than splitting engineering effort across a dozen models, Ergoflex invests all of its development into refining the 5G. The result is a mattress that has been steadily improved over multiple generations without the complexity of a large catalogue.

Eve owner satisfaction

Most owners are happy with their Eve, and the word that comes up again and again is comfortable. One owner wrote that it is “soo comfortable and the right firmness”. Another, a week or so in, said “it's super comfy now”. That settling-in period gets mentioned a fair bit, a few nights to a few weeks before the mattress feels right. A smaller group with bad backs say the pain has eased, one noting they “no longer wake up with back pain”.

Complaints are less common and tend to be specific. Some find it firmer than they expected. One wrote that it is “way too firm and has caused me back ache”. A few report early dipping: one owner on their third replacement described a mattress that “dipped at both sides”, and another said theirs “Dips in the middle and is unsupportive” within a fortnight. A few also gripe about the edges, from “sink in when sat on the edge” to “edges are so soft you nearly fall off”. Eve’s listings describe the foams as breathable, and the reviews split on heat: some owners report no overheating, while others find it “a lot warmer than our old mattress”.

Eve supportiveness

Eve Sleep mattresses are renowned for their exceptional support, attributed to the innovative use of high-quality foams and, in their hybrid models, full-sized pocket springs. The Original Hybrid Mattress, for instance, features over 800 individually wrapped 12 cm springs that respond to the body's movements, providing targeted pressure relief for the shoulders and hips. These springs are complemented by Eve's proprietary evecomfort® foam layer, which offers a springy feel to support key pressure points and maintain spinal alignment. This combination ensures a harmonious balance of support and body contouring, catering to various sleeping positions.

Eve durability

Eve Sleep mattresses feature polyester covers, known for their soft, stretchy, and breathable finish. This type of cover provides a reasonable level of durable protection, contributing to the overall longevity of the mattress. While the Eve lineup is relatively new, the bed-in-a-box mattress market has established a reputation for durability comparable to traditional mattresses. Considering that the average mattress lasts about 7 years, we have no concerns regarding the performance and durability of the current Eve lineup.

Eve best offers

We've managed to find the following top deals from across the web on Eve mattresses.

Ergoflex owner satisfaction

Ergoflex carries OEKO-TEX certification on its materials and a 10-year guarantee as standard. The 30-night trial is shorter than most current rivals, with Emma and Simba at 200 nights and Nectar at 365, but it is enough time to form a proper opinion on the feel.

The single-product model removes the decision fatigue that affects buyers shopping brands with large catalogues. There is one mattress, one feel, one price. That simplicity is a genuine selling point for buyers who find the mattress market overwhelming.

Ergoflex supportiveness

The 5G uses a 9 cm high-density visco-elastic comfort layer for pressure relief, a 5 cm cool-sleep airflow system for temperature management, and a 9 cm resilient base for structural support. The overall feel is medium firm and the foam contours to the body progressively rather than sinking in immediately. Back sleepers and side sleepers of average weight are well served.

The deep all-foam build means the 5G does not have the bounce or responsiveness of a hybrid pocket spring mattress. Stomach sleepers and restless sleepers who change position frequently during the night may find the slower foam response restrictive compared with a spring-based alternative.

Ergoflex durability

In-house foam manufacturing is the single biggest advantage Ergoflex has on durability. Because the brand makes its own foams rather than buying from third-party suppliers, the density and quality of the raw material is controlled from production through to finished mattress.

The 10-year guarantee backs the build quality, and the removable TENCEL cover helps with long-term hygiene by allowing the outer layer to be washed independently of the foam core. For an all-foam mattress at this price tier, the durability profile is strong.

Owner reviews of Eve mattresses

5 Stryder

These really are very good mattresses! One of my main concerns was the reports and even some of Eve's own documentation regarding the new smell / odour of the mattress as from experience things that give off an odour tend to make me feel unwell pretty quickly, this mattress does give off an odour but apart from a slight headache on the first night it really hasn't affected me since. No the smell does not entirely disappear after 48 hours as some say, but it does get progressively better, make sure to air the room well and regularly, also move on the mattress to get air to pass through it... hopefully if you give this mattress a chance like us you'll find it very comfortable and super supportive, if this mattress can keep delivering this level of comfort and support for 10 years it will be money well spent. It is an expensive mattress though and I would have like to see a bit more attention to a few areas, the mattress has a removable washable cover and that's fantastic, but it means the handles are located under the mattress which means lifting the rather heavy mattress to access the handles, there needs to be a better solution here. We find the mattress firmness just right but others who try it think it would be too hard for them. Overall if this mattress does last out the 10 year guarantee period then I'll have to remember to come back to this review and give it the full five stars for Quality and Value For Money but for now it's too expensive and too new to go that far.

I wrote the following review on November 18th 2020 two weeks after using my Eve Sleep Hybrid mattress. Everything I said then still applies and I love the mattress. Brilliant product and fantastic sleep every night. I have been getting up every morning for nearly a year with back pain. Knowing I wanted a new mattress, searched the internet looking at all sorts of different products with varying prices. I looked at various reviews, but none seemed conclusive, so signed up for Which. A good move because Eve Sleep was not on my list. The review for the Premium Hybrid Mattress was exceptional. I ordered online, and the process was incredibly simple. It could not be better. Notifications of delivery were brilliant, and I even got a call 30 minutes before the delivery arrival. The guys were so good and polite. The mattress comes in a box, and the instructions give all the information in a truly clear manner on how to unpack and install on the bed. I left the mattress for 24 hours before using, although this is not necessary. I knew after the first night sleeping on the mattress, it was without any doubt a brilliant purchase. I have now been sleeping on my Eve Mattress for two weeks, and it is fantastic. I look forward to going to bed and do not want to get up in the morning. The whole experience from beginning to end has been exceptional. It is very reassuring to know there are still companies that give a faultless service and have a product to match.

We bought the original hybrid mattress double after reading Which reviews, it turned out to be a on the firm side for us so we returned it after around 50 nights. The customer service, ordering, delivery and return process was excellent. We are both mostly side sleepers, I experienced hip pain/pressure during the night and had to change position often and my husband just felt that it was too firm for him. We were still a little tired through the day and put it down to our personal discomfort in the end, the mattress was supportive and we had no back pains in the morning. I had ordered a replacement mattress so that we weren't left without anything to sleep on and contacted eve to return the original hybrid once we had a delivery date. The return process was hassle free and very efficient, we found that we were able to give three dates for the return and add any comments. In hindsight, knowing that the return was so well organised, we would have trialled the mattress for longer to see if it softened up a little or we adjusted to it more as it would still have been easy enough to organise a replacement if it was needed. I was just worried that our trial period would run out before we could get anything sorted but the process was much quicker than I thought. We have still to find the perfect mattress for us and do regret the return without persevering a little longer as the replacment that we did order is terrible.
