Our Simba Hybrid Mattress Review: Is It Worth It After 3 Years?

This is a gifted product review. We were sent the Simba Hybrid mattress free of charge in 2023 in return for sharing our honest experiences. We haven’t been paid to give a positive review, and all opinions are our own. This article has been updated in October 2026 to include our experiences after three years of using the mattress.

When we first got our Simba Hybrid mattress back in 2023, I was hoping it would make a difference to my son Ben’s sleep. He has a severe house dust mite allergy, and although we had tried to be careful about his bedding and bedroom, I was interested to see whether changing his mattress might help. I also wanted him to have something really comfortable because, as luck would have it, the mattress arrived around the time he was recovering from surgery on both legs.

Fast forward three years, and Ben is still sleeping on the same mattress. Not only has he continued to find it comfortable, but we’ve also noticed a considerable improvement in the allergy symptoms that used to bother him, particularly in the mornings. I can’t say that the mattress alone is responsible for that improvement, because allergies are rarely that straightforward, but it has certainly been a positive change for us.

I thought it was about time I updated this review because, while it’s all very well telling you how wonderful a mattress feels when you’ve just taken it out of the box, I think knowing whether someone is still happy with it three years later is much more useful. After all, a mattress isn’t exactly a cheap purchase, is it? If you’re spending several hundred pounds on something, you want to know that you’ll still be happy with it long after the excitement of getting something new has worn off!

So, here’s our experience with the Simba Hybrid mattress, from those first few nights to three years later, including what we’ve noticed with Ben’s dust mite allergy, how comfortable it has been and whether I think it’s worth spending the extra money.

Why we wanted to try the Simba Hybrid mattress

Ben has several allergies, including a particularly severe allergy to house dust mites. His allergies can be serious, so we’ve always had to be mindful of the things around him that might trigger a reaction.

If you don’t have allergies yourself, it’s easy to underestimate how much they can affect everyday life. Something as ordinary as going to bed can become frustrating when you’re waking up sneezing, feeling congested or struggling to get comfortable.

House dust mites are tiny creatures that live in homes, particularly in places where there are fabrics and soft furnishings. Mattresses, pillows, carpets and bedding can all harbour them, which isn’t particularly pleasant to think about when you’re climbing into bed!

It’s not usually the mites themselves that cause the problem, but the allergens associated with them. These can trigger symptoms such as sneezing, a runny or blocked nose, itchy eyes and sometimes breathing difficulties in people who are allergic.

The NHS explains more about allergic rhinitis and how allergens, including house dust mites, can affect people.

Of course, you can’t simply remove every dust mite from your home, however much cleaning you do. Believe me, when you have someone in the family with allergies, you can become quite conscious of things that other people probably never think about!

When we were offered the Simba Hybrid mattress to review, I was particularly interested in its construction, breathable materials and comfort. I wondered whether replacing Ben’s old mattress, alongside the other things we do to manage his allergies, might make his bedroom a more comfortable place for him to sleep.

I was also curious about the mattress itself because I had heard of Simba but had never owned one. I’d always been quite practical about buying mattresses and couldn’t help wondering whether a more expensive one could really be that much better.

What is the Simba Hybrid mattress?

The Simba Hybrid mattress we received was a double mattress combining foam layers with thousands of small titanium Aerocoil springs. Unlike the traditional springs you might imagine in an old-fashioned mattress, these are tiny and designed to respond individually to your body as you move.

Our original model was described as having six layers, including Simbatex foam and a breathable cover, and was designed to offer medium-firm support.

Simba also promoted the airflow through its foam as one of the reasons the mattress should feel cooler than some traditional memory foam mattresses. I can’t tell you whether the scientific-sounding airflow figures are accurate because I don’t have a mattress-testing laboratory tucked away in the spare bedroom, but I was interested to see how it would feel in everyday use!

One thing I should mention is that Simba has changed its mattress range since we received ours in 2023. If you’re looking at buying one now, check the details of the current model rather than assuming it will have exactly the same layers and features as ours.

Our first impressions when the mattress arrived

I remember being quite surprised by how the mattress arrived. Despite being a full-sized double mattress, it came vacuum-packed in a box, which is a clever idea when you think about how awkward mattresses normally are to move around.

The box was pretty big and heavy, though, so don’t imagine you’ll be casually picking it up and carrying it upstairs on your own! Thankfully, the delivery driver brought ours to the room we wanted, which made things much easier.

Once we had it in the bedroom, two of us managed to get it into position and remove the packaging without too much trouble. It was quite fascinating watching it expand after being released from the vacuum packaging. I know I probably sound easily amused, but it really is surprising how something that arrives rolled up can turn into a proper, thick mattress!

It expanded fairly quickly, although we allowed time for it to finish taking shape as instructed.

The other thing I noticed straight away was how substantial it felt. It wasn’t flimsy or lightweight, and it certainly felt like a good-quality mattress.

We also arranged for Simba to take away Ben’s old mattress, which was a huge bonus. Getting rid of an old double mattress is one of those jobs that sounds simple until you actually have to do it.

A large collection bag arrived beforehand, and when the new mattress was delivered, the old one was taken away. We didn’t have to struggle to get it downstairs or try to work out how to fit it into the car for a trip to the tip.

I’d definitely recommend checking whether old mattress collection is available when you’re ordering, whether from Simba or somewhere else. It’s one less job to worry about!

Is the Simba Hybrid mattress actually comfortable?

This was the biggest question for me because, regardless of how impressive a mattress sounds on paper, it isn’t much use if you don’t enjoy sleeping on it.

When the mattress arrived, Ben had recently undergone surgery on both legs. He had had the tendons behind his knees cut, which meant getting comfortable wasn’t particularly easy, especially with bandages and sore legs to contend with.

As you can imagine, it wasn’t exactly an ideal time for him to be dealing with an uncomfortable bed as well!

Fortunately, he loved the mattress from the beginning. In fact, he described it as the best bed he had ever slept in, which is quite a compliment considering how uncomfortable he was after his operation.

I tried the mattress myself, too, because I was curious to know what all the fuss was about. I could immediately understand why he liked it so much.

It has that lovely combination of feeling soft enough to be comfortable but supportive enough that you don’t feel as though you’re sinking into it. I’ve tried mattresses in the past that feel wonderful for about five minutes but then seem to swallow you up, and I’ve also tried ones that feel as hard as the floor. Neither is particularly appealing!

The Simba Hybrid mattress felt like a good balance between the two.

I was also surprised that I couldn’t feel the springs. If you grew up with mattresses where you could practically count the springs through the fabric, you’ll understand why I was a little sceptical about a mattress that included them.

These are completely different, though, and the mattress feels smooth and supportive rather than springy in the traditional sense.

Obviously, mattress comfort is personal. What feels wonderful to Ben might not suit someone who prefers a particularly firm or soft mattress, but for us, it was a very good first impression.

I’ve always thought that getting a good night’s sleep involves more than simply having a comfortable bed. Things like your bedtime routine can make a difference, too, and I’ve shared some more tips for better sleep habits if that’s something you’re struggling with.

Has the Simba mattress helped Ben’s dust mite allergy?

This was one of the main reasons I wanted to try the Simba hybrid mattress, and it’s also the part of the review I most wanted to update.

When I originally wrote this article in 2023, I mentioned that Ben seemed to be sneezing less in the mornings. At the time, it was far too early to know whether that would continue or whether we were simply having a good few weeks.

Now that he’s been sleeping on the same mattress for three years, I can say that the improvement has been much more noticeable than I initially expected.

Ben still has his dust mite allergy, of course, and we still have to take it seriously, but we’ve found that the mattress has been a really positive change for him. The improvement in his allergy symptoms has been significant from our point of view, and it’s one of the reasons I’m so pleased we had the opportunity to try it.

I do want to be careful about how I explain this, though, because I wouldn’t want someone reading this to think they can buy a Simba mattress and cure a dust mite allergy. Unfortunately, it doesn’t work like that!

There are lots of things that can affect allergy symptoms, including bedding, cleaning routines, humidity, other allergens and any medication or treatment someone uses. We haven’t carried out any scientific testing to establish exactly why Ben has improved, so I can’t honestly tell you that the mattress itself is responsible for everything.

What I can tell you is that we noticed an improvement after changing his mattress, and three years later we’re still very happy with that decision.

For me, that’s a much more useful thing to share than simply repeating a manufacturer’s claims about materials being hypoallergenic.

Does a Simba hybrid mattress stop dust mites?

No mattress can be assumed to prevent dust mite exposure completely, and I think that’s important to understand before spending a lot of money.

House dust mites can live in bedding and other soft furnishings, and even a new mattress can accumulate allergens over time. A mattress being described as breathable or hypoallergenic doesn’t automatically mean it provides a complete barrier against dust mites.

If you have a diagnosed dust mite allergy, a properly fitted allergen-proof mattress encasement may be worth considering, along with suitable pillow covers and regular bedding washing.

The NHS advice on allergic rhinitis includes practical recommendations such as washing bedding regularly at 60°C or above, using a vacuum with a HEPA filter and keeping your home well ventilated.

It’s also worth speaking to your GP or allergy specialist if symptoms are severe, particularly if you have asthma or a history of serious allergic reactions.

For us, the Simba has been a good mattress, but I wouldn’t describe it as an allergy treatment or suggest that it replaces the other precautions we take.

If you’re looking at mattresses because of allergies, I’d recommend reading Allergy UK’s advice on house dust mite allergies before buying anything. It explains why proper allergen-proof covers are important and why changing a mattress alone isn’t necessarily enough.

Does the Simba Hybrid mattress keep you cool?

Another thing we were interested in was whether the mattress would help Ben feel cooler at night.

Some mattresses, particularly certain memory foam ones, can feel quite warm because of how closely they mould around your body. That’s not ideal if you’re someone who already gets hot in bed.

The Simba Hybrid uses a combination of foam and small springs, and its design is intended to allow air to move through the mattress more easily.

When we first tried it, Ben seemed to be waking up less hot and sweaty than he had been with his previous mattress, which was encouraging.

I wouldn’t want to promise that nobody will ever feel too hot on a Simba hybrid mattress, though. Room temperature, bedding, duvets and individual preferences all make a difference.

What I can say is that the cooling aspect was one of the things we liked about the mattress initially, and Ben has continued to enjoy sleeping on it.

If you struggle with feeling too warm in bed, I would also look at your duvet, pillows and bedroom temperature rather than expecting a mattress to solve everything by itself.

If you’re someone who struggles to sleep when the weather gets warmer, I’ve also shared my tips for sleeping in hot weather because sometimes even the most comfortable mattress can’t make up for a bedroom that feels like a sauna!

Can you use a Simba Hybrid mattress on an ottoman bed?

Yes, we have! Ben has a double ottoman bed, and this was something I was slightly concerned about when the mattress arrived because it was heavier than some of the cheaper mattresses we’d had previously.

If you’ve got an ottoman bed, you’ll know that the mattress sits on a lifting base, so weight can make a difference to how easily it opens.

Fortunately, ours has worked well with the Simba Hybrid mattress. It isn’t an especially expensive ottoman bed either, so I was pleased that we didn’t need to replace the bed frame just to use the mattress.

That doesn’t necessarily mean every ottoman bed will be suitable, though. If you’re thinking of buying a Simba for an existing ottoman bed, I’d recommend checking the mattress weight and the maximum weight supported by your particular lifting mechanism.

It’s definitely worth checking before ordering, especially if you regularly use the storage underneath.

If you’re replacing your bed as well as your mattress, you might also find my guide to redesigning your bedroom useful. There are lots of things to consider when you’re choosing furniture, especially if you need plenty of storage.

Our Simba Hybrid mattress review after three years

I think this is where the review becomes particularly useful because we’ve now had the mattress long enough to know whether it was something Ben genuinely liked or whether he was simply enjoying the novelty of a new bed.

He’s still using it in October 2026, three years after it arrived, and he’s still very happy with it. For me, that says quite a lot. A mattress might feel wonderful when it’s brand new, but if you find yourself wanting to replace it after a year, it probably wasn’t such a bargain after all.

The comfort has continued to suit Ben, and the improvement we’ve noticed in his dust mite allergy symptoms has been a particularly welcome benefit.

I also think it’s worth remembering that we originally tried this mattress at a time when Ben really needed to be comfortable because of his surgery. It wasn’t simply a case of trying a new mattress for a few nights and deciding it felt nice. He was recovering from an operation that made finding a comfortable sleeping position difficult, and he found the Simba hybrid mattress supportive and comfortable throughout that period.

Three years later, it is still the mattress he sleeps on.

I haven’t carried out formal measurements of how much the Simba Hybrid mattress has changed over time, so I’m not going to pretend I’ve tested its firmness or support in a laboratory. This is a real-life review from a family that has actually been using it, and I think there’s value in that.

Of course, looking after a mattress properly makes a difference to how long it lasts, too. I’ve shared some more advice in my guide to caring for your mattress, including cleaning, protection and when it might be time to replace one.

Is the Simba Hybrid mattress worth the money?

This is probably the question most people want answering, particularly because Simba mattresses are not usually the cheapest option.

I’ll be upfront here: we were sent ours free of charge, so I haven’t personally had to make the decision to spend several hundred pounds on it. I think that matters when reviewing something expensive, because it’s easy to recommend a product when you haven’t had to pay for it yourself.

However, having seen how comfortable Ben has been and how much we’ve appreciated the mattress over the last three years, I would certainly consider buying one.

I used to be quite sceptical about spending a lot of money on a mattress. I’ve always thought that, as long as it was comfortable and did the job, there wasn’t much point paying considerably more. Trying the Simba hybrid mattress has changed my opinion a little.

I still don’t think everyone needs an expensive mattress, and I wouldn’t encourage anyone to spend more than they can comfortably afford. There are perfectly decent mattresses available at lower prices, and the most expensive option isn’t automatically the best one for you.

However, I do think it’s worth considering how much time you spend in bed and how long you expect a mattress to last.

If you spend £600 on a mattress and use it for ten years, that works out at £60 a year, or roughly 16p a night. Obviously, that doesn’t make £600 magically appear in your bank account, but it does put the cost into perspective!

You also need to consider the support, comfort, guarantee and trial period rather than simply comparing prices.

Simba has offered lengthy sleep trials and guarantees on its mattresses, but I’d recommend checking the current terms before ordering because these can change.

For our family, the Simba Hybrid mattress has proved to be a very worthwhile addition to Ben’s bedroom.

How to choose a mattress if you have a dust mite allergy

If you’re reading this because you or someone in your family has a dust mite allergy, there are a few things I would think about before choosing a new mattress.

The first is to remember that a mattress is only one part of the bedroom. There’s not much point spending a fortune on a new mattress and then forgetting about the pillows, duvet, bedding and other places where allergens can accumulate.

I’d also be wary of buying something simply because it’s described as hypoallergenic. It’s a lovely word, but it doesn’t always tell you very much about how effective a product is at reducing exposure to a particular allergen.

The NHS guidance on reducing dust mites at home is worth reading if you’re trying to make a bedroom more allergy-friendly. It covers everything from specialist mattress covers to cleaning, ventilation and humidity.

Instead, I’d look at how easy the Simba Hybrid mattress is to care for, whether it can be used with a suitable allergen-proof encasement and whether the manufacturer’s cleaning instructions are practical for your household.

For someone with allergies, I’d also consider the following:

• A proper mattress encasement. Look for one designed to provide a barrier against house dust mite allergens, rather than assuming an ordinary mattress protector will do the same job.
• Washable bedding. The NHS recommends washing bedding regularly at 60°C or above where the fabric allows.
• Bedroom ventilation. Keeping the room dry and well ventilated can help manage the conditions in which dust mites thrive.
• Cleaning routines. Damp dusting and vacuuming with a HEPA filter can help reduce exposure to allergens.
• Comfort and support. Having an allergy doesn’t make comfort any less important, so choose a mattress that suits the person sleeping on it.

I’d also suggest being realistic. Even if you do everything recommended, you may not be able to remove all dust mite allergens from a home.

If allergies are affecting sleep or everyday life, it’s worth seeking medical advice rather than relying entirely on changes to bedding and furniture.

How can you get a Simba hybrid mattress for less?

If you like the idea of a Simba hybrid mattress but the price makes you wince a little, I completely understand!

One thing I’d suggest is keeping an eye on the Simba website rather than automatically paying the first price you see. Like many retailers, Simba runs promotions at different times of the year, and it may be worth waiting if you’re not desperate for a replacement immediately.

I’d also think carefully about whether you actually need a whole new bed or just the mattress. If your existing bed frame is suitable and in good condition, replacing only the mattress could save you quite a bit of money.

Before ordering, check the current trial and return conditions, particularly whether any collection or delivery charges apply. It’s also worth making sure the mattress is compatible with your bed frame.

Personally, I’d rather save for the mattress I really wanted than rush into buying something purely because it happened to be discounted.

Frequently asked questions about the Simba Hybrid mattress

Is the Simba Hybrid mattress good for someone with a dust mite allergy?

We’ve had a very positive experience with it. Ben has a severe dust mite allergy, and we’ve noticed a significant improvement in his symptoms since changing his mattress. However, this is our personal experience, not proof that the mattress prevents dust mite exposure or treats allergies. Appropriate allergen-proof covers and other allergy management measures are still important.

How long does a Simba Hybrid mattress last?

Simba mattresses have been sold with long guarantees, although you should check the terms for the model you’re buying. We’ve been using ours for three years, and Ben is still very happy with it. I can’t tell you how it will feel after ten years, but I’ll continue updating this review as we use it.

Is the Simba Hybrid mattress too heavy for an ottoman bed?

Our double Simba Hybrid has worked well on Ben’s ottoman bed. However, different ottoman beds have different weight limits, so check the manufacturer’s guidance for your bed before buying.

Is the Simba Hybrid mattress firm or soft?

Our 2023 model was described as medium-firm, and that’s a fair description of how it feels to us. It has a comfortable, cushioned feeling without being excessively soft. Of course, how firm a mattress feels can vary depending on your weight and sleeping position.

Is a Simba mattress worth buying?

For us, yes. Ben has used his for three years and continues to find it comfortable. We have also noticed a considerable improvement in his allergy symptoms since replacing his previous mattress. I wouldn’t say everyone needs to spend this much on a mattress, but our experience has been very positive.

My final thoughts on the Simba Hybrid mattress

When we first received the Simba Hybrid mattress in 2023, I was impressed by how comfortable it felt, and I was delighted that Ben liked it so much, especially while recovering from surgery.

What I didn’t know at the time was whether we’d still feel the same way several years later.

Well, here we are in October 2026, and Ben is still sleeping on it. He continues to find it comfortable, and we’ve seen a really positive improvement in the allergy symptoms that used to bother him.

For me, that’s far more convincing than any fancy description about springs, foam layers or cooling technology.

I know how frustrating it can be when someone in your family has allergies and you’re constantly trying to work out what might help. You don’t want to spend a fortune on something only to discover it makes no difference, and you certainly don’t want to be persuaded by unrealistic claims.

I can’t promise that the Simba Hybrid mattress will make the same difference to someone else’s allergies, and I wouldn’t suggest buying one as a substitute for proper allergy management. What I can say is that we’ve been extremely happy with ours, and I would happily consider buying another.

Of course, a comfortable mattress isn’t the answer to every sleep problem. If you regularly wake up exhausted despite spending plenty of time in bed, I’ve written about why you might feel tired even after sleeping all night and some of the things worth considering.

If you’re considering a Simba hybrid mattress, I hope our experience helps you decide whether it’s right for you. And if you already have one, I’d love to know how you’ve found it, especially if you’ve been sleeping on yours for a few years too.
