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.

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.

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.

Simba Best Offers

We've managed to find the following top deals from across the web on Simba 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. Independent reviews consistently highlight edge support, motion isolation and durability as the three areas where the 5G scores strongest.

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. This consistency is one of the reasons the 5G has accumulated positive durability reviews spanning years of real-world use.

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.

    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! ??
