Simba

Simba have been around for a long time originally founding in 1979, however, they have only been in the bed-in-a-box industry a few years at this point. Simba started its journey with one mattress before branching out to encompass an entire range. These aren’t just any mattresses though, and they have been tested using data from ten million sleepers’ body profiles and over 100 prototypes to help ensure that the mattress and its design will suit the vast majority of sleepers. To date the Simba lineup has become one of the most well-reviewed mattresses worldwide and with the new line-up, there's different models to suit different budgets.

Simba has an entire lineup dedicated to bed in box rolled mattresses. This avenue to market has become increasingly popular in recent years and has numerous benefits, namely that the cost of the product is typically lower due to savings within logistics warehousing and delivery.

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.

Simba Owner Satisfaction

Satisfaction for Simba is high on their priority list, offering an impressive comfort guarantee which means that if you are not 100% satisfied with your purchase you are able to organise a return for a full refund. The return process is one of the easiest we have come across and involves letting the company know and they will arrange collection at a time convenient to you. Additionally, there are no additional surcharges, costs or delivery fees associated with the returns process which means you get 200 nights risk free to try the mattress.

After this trial period you will also receive a market leading 10 year guarantee that will further instill confidence and ensure your investment is protected long term.

Simba Supportiveness

Simba have multiple mattresses in their range, however all offer roughly the same level of supportiveness coming in at a medium firm tension. The comfort that you derive from a mattress will generally come from the top layer that sits somewhat detached from the support layer. The support layer is what contours and fights against your body to give you pressure relief. Depending on how you sleep or how much you weigh are both factors in determining suitability of tension. With the medium firm support of the Simba lineup we find them most suitable for back sleepers and those of average or heavier build. That said, due to the inclusivity that Simba has aimed to achieve through its prototypes and extensive testing, we do have plenty of reports of side sleepers and those who are lighter getting maximum comfort out of the lineup.

Simba Durability

People are increasingly expecting more from their mattresses with more comfort and more support on offer than ever before. It’s actually a really great time to buy a new mattress as companies new and old are changing the way they do business and produce mattresses with improvements and savings along the way. The same has become true for durability and while the average lifespan of a mattress before being replaced currently lies at around 7 years, the Simba goes above and beyond with a guarantee covering a full 10 years. The result of mattresses lasting longer is the cost of sleep actually decreases relative to cost and time meaning products like Simba may be cheaper in the long run due to that enhanced and increased durability.

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.

My Love Affair with the Simba Hybrid Pro Mattress From the moment it arrived, compactly boxed and ready to unfurl its magic, the Simba Hybrid Pro mattress promised something special. And after countless nights of blissful, restorative sleep, I can confidently say it has delivered on every single promise - and then some. This isn't just a mattress; it's an investment in unparalleled comfort, ingenious design, and truly transformative sleep. The first thing you notice is the immediate sense of luxurious comfort. Simba rates it as a medium-firm, and I'd say that's spot on. It's not a sink-in-and-get-stuck kind of soft, nor is it a rock-hard surface. Instead, it strikes that elusive perfect balance: a plush, comforting top layer that cradles your body, seamlessly supported by a robust, responsive core. The magic truly lies in its unique layering system. The natural wool layer is a game-changer, providing a breathable, sumptuously soft feel that keeps you cool in summer and cosy in winter - a genius touch for anyone who struggles with temperature regulation. Beneath this, the innovative Simbatex foam, infused with cooling graphite, works tirelessly to dissipate heat, ensuring you never wake up feeling clammy. But the real unsung heroes are the dual layers of Aerocoil® micro springs. These tiny, conical titanium alloy springs are individually responsive, providing tailored support that adapts to your body's every curve and movement. As a restless sleeper, I've noticed a significant reduction in tossing and turning, and my partner's movements are practically imperceptible thanks to the excellent motion isolation. Beyond the incredible comfort, the Simba Hybrid Pro boasts exceptional build quality. The firm borders, thanks to Simba's Edge Lift Technology, mean you can utilize every inch of the mattress without feeling like you're about to roll off - a fantastic benefit for couples or those who spread out. It's clear that every detail, from the breathable cover to the ergonomic support zones in the base foam, has been meticulously designed to promote optimal spinal alignment and pressure relief. I've personally experienced a noticeable improvement in any morning aches and stiffness since switching to the Hybrid Pro. And let's not forget the practicalities. The mattress arrives conveniently rolled and boxed, making it surprisingly easy to manoeuvre, even for a king-size. The removable, washable cover is a hygiene godsend, keeping your sleep environment fresh and clean. While it sits at a premium price point, the Simba Hybrid Pro is an investment that truly pays dividends in quality of life. It's no wonder it's garnered so many accolades and glowing reviews from independent experts and sleepers alike, including a Which? Best Buy award. For anyone seeking a mattress that offers the ultimate blend of cloud-like comfort, unwavering support, and intelligent temperature regulation, the Simba Hybrid Pro is, quite simply, a dream come true. Prepare to experience sleep redefined.

after using the Simba Sleep Mattress for a while now, I can say I am thoroughly impressed with the Luxe Hybrid Mattress, I looked around for a while for a new mattress and decided on Simba because of the myriad of technologies they include in their hybrid mattresses, not to mention their recycling and carbon neutral credentials. This is the first time I've had a mattress which uses both springs and their version of memory foam which they call Simbatex foam. This Hybrid format is the perfect mix of comfort and stability. I do have back pain problems and this bed really helps that, I wake up and have no back pain whatsoever, it's a noticeable improvement. The Mattress is quite tall, but that's because of all the different layers contained within the mattress. It is meant to be Medium to Firm when it comes to its firmness level, which I agree with, I normally like the mattress to be on the firm side, but it looks to me that the springs provide the best support no matter which position you sleep in, yet the Simbatex Foam, the breathable Zip Off Cover and the Mattress Protector (both of which you are able to throw in the washing Machine) all add up to a very comfortable sleeping experience. I had a very positive experience with Simba Sleep, from the start of ordering the mattress, having it delivered in a small box, and then opening it up, letting it take shape on the bed frame, and within hours I had a bed ready to sleep in. The policies they have like 200 night trial, 10 year guarantee, old mattress removal and free next day delivery leaves me to believe that Simba Sleep is not just out to sell you a mattress, they have clearly made a product they can be proud of and that can be relied upon to help you sleep and to last a number of years. All in all, I'm very happy with my purchase and I am sure I will be buying more and can more than recommend them for a quality product which stands out from the rest. I actually look forward to going to sleep now.

Having trouble during 5 year with same mattress is hurting our back, we went purchase another mattress from online with high great review turn out wasn't very comfort to sleep, we got 3day day returned policy left we had to act quick to find another mattress, Heard and seen about this simba mattress through family said they have the same then they love the mattress, price wise cost alots so we decide to give it a try purchase and if it didn't suit us we can return it back before 200 night. After we paid for it we got it very quickly delivery same day the other mattress just in time returned back before deadline returned policy otherwise we be sleep on the floor! Shortly after purchase to over two week we slept like on the cloud! It's super comfort! We had a sore sciatica from old mattress and after new simba mattress we never felt any sore sciatica again! My wife have a really sore back for many years with tried many different mattress, she have been grumpy and moan about her back. Lately I didn't hear her moan or grumpy again! We hope this will continue sleep comfort on the simba bed on long term! It's definitely worth it! Only thing we got bugger is we purchase several day before the Halloween promote deal! But good thing is simba you buy a mattress it's come with worth £800 free pillow, mattress topping and duvet! The topping is very comfort and soft, something felt warm to sleep on it. Perfect fit the king mattress. Everyone have different back problem but I am a chef working long hours with over 24k stepping/climbing and lifting heavy on top with sleeping on old mattress was very miserable after getting out of bed to work. But after couple week with new simba I got out of bed with no pain in back and walk to work like I had a great sleep! It's does look cost expensive but they offered a finance monthly deal that can help spread the cost over 3years or returned back within 200 night and money back. Thanks simba! ??

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.

Issues with delivery 1st attempt only the mattress topper arrived no mattress? Resolved following week with the help of Eve chasing logistics company. The Premium Hybrid Mattress King size is extremely heavy and glad we paid for 2 man delivery who struggled with the box up to the bedroom, interestingly the details on opening the box and mattress are actually printed on the inside the box? Unpacked the mattress and left it to inflate for a few hours .we both have found the mattress very comfortable on the firm side of medium. Only issue we have had was with the strong musty smell that has taken at least 1 month to fade and even now when you have left the bedroom door closed all day you get a faint whiff of it have 1 month left of the trial so will monitor it .The Handles for turning the mattress are located underneath the mattress i assume as being so heavy they would probably soon rip of the side of the mattress, this makes rotating the mattress very awkward as the mattress is extremely heavy ,due for a rotation this week so will get my son and daughter to do it for us. Think anyone should consider this as needs to be done regularly think there is a lighter hybrid version which on reflection would have been better for a pair of old codgers like us...for all my moans I must say it's very comfortable and appears to be of very good quality.......keep safe.

Marketing over promises how good this mattress is. It is not bad but it is not brilliant either. Outer materials feel very synthetic and, as usually the case with rolled mattresses, is not double-sided. Make sure you get a decent discount - Eve play games with them but 25-35% off seems the target. I waited until it went down in price to about what it was 30+ days before. Feedback: Firstly, the super king is very heavy and, probably for some good reason, it unrolls upside down and has to be "flipped". There are some pointless handles on the bottom but they don't really help. We struggled. Secondly, the corners took a long time to go to shape - at least 48 hours. Next, the sides are very soft so collapse when you sit on them which is okay as long as you can easily get up to standing or do not want to sit there. Finally, the comfort to sleep on: this is a foam-topped mattress which means you sink into the foam layer with support underneath from springs. The top is soft and quite warm but kept cool by lots of dimples which you can feel. The core is firm and supportive. Overall result is that you are very aware of the foam and the bed is soft but also stays very flat. It improved my sleep after having a traditional and sagging Warren Evans mattress but don't expect miracles. We decided to keep the mattress - so do not be too put off.
