Eve

Eve Sleep emerged in 2014 as a prominent online retailer specializing 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 customize their sleep experience.  Eve Sleep provides a 200-night trial period, enabling customers to thoroughly test their mattresses.

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.

Eve Owner Satisfaction

Satisfaction with Eve Sleep mattresses remains high, with a solid score at the time of writing. Many owners praise the balanced comfort and support, particularly in the brand’s hybrid models, which combine foam and pocket springs for a responsive yet cushioned feel. Unlike some all-foam mattresses, Eve’s construction helps to minimise heat retention, with breathable layers designed to promote airflow throughout the night. That said, a handful of users have noted that the firmer models can take some getting used to, especially for those accustomed to softer sleep surfaces.

When it comes to pressure relief and spinal alignment, Eve mattresses generally receive positive feedback, particularly from those with back issues. The medium-firm options tend to provide good lumbar support, while the softer models cater well to side sleepers who need more contouring. However, some users have mentioned that edge support isn’t as strong as they’d like, meaning there can be a slight dip when sitting on the side of the bed. Despite this, the overall consensus is that Eve Sleep delivers a well-balanced sleeping experience, blending comfort and support in a way that suits a wide range of sleepers.

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. User feedback indicates general satisfaction with the expected lifespan, and 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.

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.

We absolutely love this mattress as it's so comfortable. It feels really firm when you first get into bed, like it's just to hard, but as it warms with your body heat it softens where you are lying, making it really comfortable. Great for a bad back or anyone who like a firmer bed. The only downside is our fitted sheets slide and bunch up through the night and even having bought some elasticated bed clips it's still an issue. Not sure if taking the removable cover off and just using a mattress protector would better? Either way it doesn't detract much from it being the best mattress we've ever had and at the price was considerably cheaper than our last one, making it excellent value for money too. All in all I would definitely recommend it for anyone needing a firm mattress or anyone with back issues. We sleep so well that I wish we'd bought it earlier, but are very happy to have it now.

5 Tracey W

My daughter wanted a soft but not sinkable double mattress with her new bed. Bensons were so helpful and very patient. Eventually she settled for the Hybrid duo plus and absolutely loves it. No negatives at all, ok there is a smell to begin with but not overpowering. So we bought the same for one of our spare bedrooms. Having autoimmune arthritis I have spent years in agony lying in bed, unable to sleep on any side even considering sleeping in a lounge chair. Assuming it was my arthritis getting worse I didn't consider the mattress until I had to move into the spare due to having the master renovated, I was really apprehensive also because I need a king size as I'm constantly moving around. Well it was a revelation, I had no back pain! I'm still in the spare room and will definitely be buying one very soon but a king size unfortunately to fit my bed. 5 star comfort for me.

5 David L

I can't say enough good things about this mattress! From the first night, I noticed a huge difference in my sleep quality. The perfect balance of comfort and support keeps me feeling well-rested and free of aches in the morning. It contours to my body just right, without feeling too soft or too firm. Another big plus is that it stays cool throughout the night-no more overheating or tossing and turning! The materials feel high-quality, and even after weeks of use, there's no sagging or loss of support. If you're looking for a mattress that will improve your sleep and overall well-being, this is the one to get. Highly recommend!

5 Sophie J

I am so pleased with choosing Benson for Beds. They have been so helpful from start to finish. I had lots of updates from Bensons reminding me of when my mattress will be delivered. They turned up as scheduled and were so professional and advised me on how to take care of my new bed. I am so impressed with the quality and comfort of this mattress. It is so comfortable! I have definitely chosen the right bed for me! I have also got an ottoman bed frame from Bensons at the same time. It has so much space underneath and it looks so modern and stylish in bed bedroom. I couldn't be more happy with choosing Bensons for Beds!

5 Aimee B

Overall, the Evie Duo Hybrid feels really well-made and worth the money. It's comfortable, adaptable, and I wake up without aches or stiffness. Definitely one of the best mattresses I've tried! It feels super supportive around the edges, and I don't sink in too much when I sit or lie near the side. My partner moves around a lot at night, but I barely feel it. I've been sleeping on the mattress for a few weeks now, and I'm really impressed. It has the perfect mix of softness and support. It's honestly the first mattress I've had that makes me look forward to going to bed every night.

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.
