My initial impressions were dominated by its feel. Stretched over the intricately structured mattress, the luxurious soft-touch, breathable stretch knit cover felt like a gentle caress against the skin. Simply put, it exuded soothing comfort—and I’d barely even begun! The mattress is delivered rolled conveniently in a box which is an absolute blessing for those torturous manoeuvres up the narrow British staircases.
One of the main highlights of the Simba Sleep Hybrid Ultra Mattress, that I truly admired, is its mindfully crafted, high-tech, triple-layered Aerocoil® conical springs which total to a whopping 6300. These are not just any springs, these are intelligently responsive springs which are designed to offer optimum personalised, contoured pressure relief and support. The real cherry on top here is that these little pillars of wonders do not just serve an aesthetic purpose. They go a step further. They enhance air flow, which aids in regulating your body temperature as you sleep, and diminish motion transfer for what they call the 'zero disturbance factor', dealing a significant blow to the nagging issue of partner disturbance during sleep.
Immersion gets a whole new meaning with the Simba Hybrid Ultra Mattress’s FusionCool™ layer. Comprised of naturally sustainable wool, kapok fibres and charcoal-infused bamboo, this layer tirelessly works to create a temperature-regulating microclimate inside your mattress to ensure you enjoy a “fresh” sleep environment. My first encounter with this feature was rather surprising and I could instantly feel the material interacting uniquely with my body, the effects of which I’m sure would be magnified during a full night’s sleep.
I was honestly intrigued by the dual Simbatex® foam layers—two 25mm-tall pillows of comfort that not only amped-up the cushioning factor but also worked meticulously to improve air circulation. Their graphite infusion means they actively help release heat and humidity, promising a fresher sleep experience—a feature that we can all appreciate.
Support in a mattress is non-negotiable, and the Simba Sleep Hybrid Ultra Mattress certainly does not negotiate on that. Their intelligent incorporation of the PureLift™ support boosting layer, a benevolent blend of latex and coconut fibres, took me by surprise as it provided a noticeable boost to the mattress's support factor; something I believe future sleepers will truly appreciate. It was clear that they had not cut any corners when it came to ensuring a stable, restful sleep.
The CertiPUR® stabilising core foam offers the mattress its backbone, its complete integrity and quality. Each contour, each pressure point of your body is responded to with precision. The SupportCore™ Sprung Base added an extra level of support and maintained breathability, a quality I noticed during my in-store testing that is guaranteed to be beneficial during warmer nights. Needless to say, I believe the mattress offers a sleep experience that would feel tailored and would be responsive to the sleeper.
While the advanced features mentioned above spell out the Simba Sleep Hybrid Ultra Mattress's superior quality and thoughtful design, it's the minor details that sew together this exquisite piece of sleeping technology. MTick accredited as being menopause-friendly by GenM for its potential to alleviate night sweats—a critical detail which puts the brand ahead in terms of reaching a broader audience, in my opinion.
Also, the cool-touch treatment of Stratos® on the top cover of this mattress proved to be a small yet indispensable detail that pays off by providing a comfortable sleep throughout the year. While major aspects like the various advanced layers and technologies significantly contribute to the comfort and support of the mattress, it's these minor inclusions that shout out Simba Sleep’s commitment to serving all customers, irrespective of their unique requirements.
However, no product is perfect and during my test, there were aspects that I believe could see improvement. The first gripe—I found the zip-off top cover a bit fiddly to handle. Although a minor detail, I feel, a smoother zip system would perfect the otherwise well-thought-out product.
Another point of contention is the 'medium to firm' comfort choice. While during my in-store test the firmness seemed adequate, especially for back sleepers, I have reason to believe side sleepers, particularly those with an hourglass figure, might require a softer tension for a more tailored sinkage. However, this is highly subjective, and the firmness level can be a perfect fit for many.
Lastly, while Simba Sleep provides a free 10-Year guarantee, in my experience, a longer warranty period or a trial period can go a long way towards winning the trust of a customer. Not everyone will be comfortable investing in a product without getting the chance to spend a considerable amount of time on it or knowing their investment is covered for an extended period.
Overall, my in-store test experience of the Simba Sleep Hybrid Ultra Mattress was impressive. Loaded with a combination of smart technologies and well-thought-out design considerations, it offers a personalised sleep experience that is a level above its competition. With its unique blend of comfort and support, it’s evident that Simba Sleep knows how to craft a fabulous mattress. Of course, there is always room to improve and the firmness tension could be tweaked a bit. However, I find this mattress promising and highly recommend it to anyone seeking a sleep experience that combines modern technology, comfort, and support.

Had an okay experience with this, it's certainly more toward the firm side. The cool-touch cover is a nice addition but don't expect any miracles from the temperature regulation features.
The Quality of the mattress is second to none. It's the best nights sleep I've had in a long time and feels truly comfortable. It supports me nicely and you can feel the layers when sitting on the edge of the bed it doesn't sink it stays firm but comfortable. The air flow feels great too and I can regulate my temperature really well.
We have had our Ultra Mattress for about 3 weeks now !!! It's amazing it's soft in the right places , it's big so lots of space , can't feel my husband moving around which is the best thing as he jumps instead of turning !!!! Now he no longer wakes me up!
Got goods but Rhenus were a disaster. Cancelled delivery an hour after due time then took 10 days later to deliver. Crew not happy to assemble bed and take away packaging though. I had a remove mattress deal
Just had the ultra mattress for a couple of weeks and im really happy with it as is very comfortable and has grat support
The mattress is fantastic upgrade on previous mattresses I've had in the past! When looking at it, it's quite amazing the tech that's gone into the final product. This combined with the duvet is perfect for temperature control at night
This mattress has worked wonders for my back, I had an old memory foam mattress and nothing compares to the quality of this product. The comfort is second to none. Struggle getting out of bed in the morning now. The balance of this mattress with my partner next to me is excellent would recommend this hybrid ultra mattress to everyone for a brilliant nights sleep.
After putting off buying a new mattress we finally upgraded and it's a game changer. We sleep for longer without so many wake ups during the night. I only wish we did this earlier!
We waited for the delivery of the mattress for some weeks due to stock issues. However, the delivery itself went smoothly - 3 people were needed to take the mattress to our bedroom on the first floor. The mattress itself is very comfortable, with just the right level of firmness. We opted for the super king size and it is VERY big, with the two of us able to sleep without disturbing the other person while getting up at night. It is a bit too early to decide whether the mattress is worth the expense - at this stage, we can say it is much more comfortable than our previous (6-year-old Simba) mattress.
We are extremely pleased with our mattress. Delivery met every promise. Although quite expensive we think it is well worth it.
Great mattress really comfortable, makes me want to stay in bed forever.
This is a very comfortable mattress and I would readily recommend it
So far so good Firm but comfortable Back ache seems to have reduced after 2 weeks Customer service good when needed to return a duvet we ordered at the wrong size Highly recommend
Great buy highly recommended
OMG what a difference this mattress has made. No more waking up restless and sore. I got the pillows and duvet with it aswell and my sleep is now so comfortable. So glad I got it. Happy rested mumma happy kids. I highly recommend it.
We decided to 'push the boat out' and treat ourselves to a posh new mattress. We were not keen on a memory foam type mattress but wanted one with springs. Our King Sized Simba Hybrid Ultra Mattress did not arrive vacuum packed but the delivery crew did a grand job of getting it upstairs onto the bed. The mattress is very high quality as would be expected at the price. To be truthful we found it a bit firmer than we expected but it is early days and we are both getting a good nights sleep. The mattress is pretty heavy but the handles on all sides will help enormously when it comes to the required rotating dates. All in all we are very pleased with our purchase from Simba.
I love the mattress, it's the perfect blend of firm but also slightly springy, the difference it's made to my back so far is incredible! I'd say my only mild issue is that none of the super king sheets I buy fit it and the mattress is very heavy and hard to put sheets on. But in all other ways and the most important way (good sleep) it's amazing and can't be faulted.
I was unsure what to expect having not used this company before. Not only is the mattress extremely comfortable, but I believe excellent value for money when compared to similar products of equal quality. The delivery was seamless and I was kept fully informed at every stage.
Had my new matress for a couple of weeks now. Sleeping like a baby!
We are really happy with this mattress so far. We bought the most expensive one as it was on offer. Our last mattress was already pretty high end but purchased eight years ago and so perhaps a little worn. This is a huge improvement. My wife is a really light sleeper and we have a small child and any movement in the bed normally wakes her, as does getting too warm at night, which (on top of being woken up very regularly by the little one) has made it hard for us to go back to sleeping in the same room post baby. She says the new mattress is like sleeping on air. It is very comfortable, pillowy, bouncy and firm somehow all at the same time, and it has substantially reduced movement from waking her up (it doesn't entirely wipe it out so there is still some, but a huge improvement on our last one). She says it also feels cooler. We are already spending a lot more time in bed as a family now, to want movies and on weekend mornings which is nice as the little one loves it too. We are only two weeks into using it but definitely a very very promising start. Happy Customers!
Specifications without the jargon, easy to understand and digest.
A height of 34cm often indicates a mattress that features multiple layers of material, providing a balanced composition of support and comfort. The density, however, could make it a touch challenging for people with mobility issues or for those preferring a low-profile bed setup.
This 100% UK made product is the perfect choice for a home with a sense of individuality. Sleep in comfort with the knowledge that you'll waking up refreshed and ready for another day.
