Is the Simba Hybrid Pro mattress the perfect mattress for you? Considering the price tag, we're sure you want to make sure that it is! So, let's take a deep dive and see what this premium mattress is all about.

If you are in the market for a high-end, hybrid mattress, the Simba Hybrid Pro mattress might be a good choice. The 7 layers of comfort promise to bring the ultimate sleeping experience, but is that really the case?

It's Simba’s second-generation mattress after their original Hybrid, and they claim to have DOUBLED the comfort and doubled the support! But… Have they taken sleep to the next level? We’ll go into more detail about this premium mattress in our Simba Hybrid Pro Mattress review.

Who is this mattress for?

Simba Hybrid Pro is a medium-firm mattress designed to be an adequate fit for everyone, regardless of their sleeping position or body weight. It is the mid-tier mattress from Simba, although, with its price tag, it is hard to look at this one as anything but a luxury option.

Apart from the price tag, this Simba mattress is most definitely one of the most well-rounded mattresses on the UK market that has a patent that takes the quality of sleep to the whole next level.

What do we use this product for?

Thanks to the layers used in this mattress, it enhances breathability and keeps your body at an ideal temperature. Not only that, you will feel comfort from the top layers and supported by the ones beneath. Everything you would expect from a hybrid mattress is achieved in the Simba Hybrid Pro. In short, it is for:

Features you should know about the Simba Hybrid Pro mattress

Like any other mattress, Simba Hybrid Pro has its own set of defining features and characteristics. So, before you go out and buy this pocket-sprung mattress, we thought you should probably know a bit more about this mattress.

7 different layers

As we've mentioned in the beginning, Simba Hybrid Pro has seven different layers that make up the body of the mattress, with the seventh layer being the removable cover.

All in all, the mattress consists of (in the top to bottom order) of super soft & breathable sleep surface, natural wool layer, Open-cell Simba-Pure layer, two titanium Aerocoil spring-comfort layers, high definition Simba-Pure with Simba Pure edge support layer and a zoned Simba-Pure support base. Each individual layer serves its purpose, which you’re about to see in the following of this section.

Temperature regulation wool layer

Underneath the super soft, breathable sleep surface lies a temperature-regulating natural wool layer. As you know, memory foam mattresses can get very hot, which is precisely why Simba has added a natural material to their Pro model. Apart from being super soft and quite comfortable, wool is also naturally moisture-absorbing and temperature-regulating.

Now, it is important to note that the luxurious natural wool layer won’t cool you. Temperature regulating does not mean cooling – it just means that it does a great job of dispersing body temperature and adapting to temperature conditions. This translates to a heat-regulating sleep surface layer that is going to keep you warm during the winter and pleasantly cool during the summer.

Simba OpenCell Pure foam

The memory foam layer is another thing that sets Simba mattresses apart from other brands.  Beneath the temperature-regulating wool layer is the Open-cell Simba-Pure foam layer. This is a high-definition foam layer specially designed by Simba. They’ve done their fair share of research to make this specially designed foam to keep their mattresses more comfortable, and possibly even more important – improve the airflow and temperature regulation.

Unlike Simba Hybrid Luxe, this one is not infused with graphite for improved cooling, but it is still quite good at doing what it needs to be doing.

Breathable cover

This Pro mattress comes with a high-quality, hypoallergenic, knitted cover.

This top cover on the Simba Hybrid Pro is removable; therefore, it is also machine washable.

The cover is exceptionally made. It is made from high-quality polyester and elastane. It is very soft and pleasant to the touch and is lovely to lie on. With that being said, we'd still suggest using a sheet or a mattress protector with this mattress.

5,000 25 mm conical pocket Aerocoil springs

As we’ve mentioned, unlike the majority of traditional mattresses, Simba Hybrid Pro contains two layers of titanium Aerocoil spring-comfort layers.

As you could tell from the name and the number of coils – Aerocoil pocket springs aren't regular pocket springs. They are much smaller than the typical pocket spring, with each being only 25 mm tall. This makes them quite a bit softer and not as supportive as the regular pocket springs. That is precisely why these two layers are called spring-comfort.

While they do provide a certain level of support, these two layers of pocket springs are mostly there for comfort. As you could guess, the great amount of springs helps evenly distribute weight, improves contouring but reduces the chance of sinking. While we're on the subject of the amount of the springs, it is important to note that the number will be dependent on the size of the mattress, meaning the bigger the mattress – the more Aerocoil springs.

CertiPUR and TCPP Free Certificates

Now that we've covered each individual layer and its purpose, it is important to note that this mattress is perfectly safe for human use. Simba mattresses are known for their chemical-free products. All of the foams and materials that are used in the manufacturing of this mattress are CertiPUR certified. What this means is, that all of the foams and the materials used are TCPP-free, which means that they're free of any potentially harmful chemicals and heavy metals.

You won’t find any traces of phosphates, parabens, biocides or any other organic pollutant in this mattress.

Handles for easy moving

Simba advises you to rotate your mattress once a month for the first three months and then continue rotating it after every three to six months. You don't have to flip the mattress, as it is not double-sided, but you do have to rotate it – unless you want to void your 10-year warranty.

However, Simba Hybrid Pro can be quite heavy. The king-sized mattress weighs over 30 kg, and when you factor in that this is a 28 cm deep mattress, it is easy to imagine rotating it would be quite tasking.

Fortunately, this Simba mattress comes with four handles for easier manoeuvring. That is if you get a mattress that's larger than a Small Double. Single and Small Double mattresses do not come with handles, but they're more compact and easier to move around.

Review of Simba Hybrid Pro mattress

Image of a TSA reviewer reviewing the simba hybrid pro mattress

The Simba Hybrid Pro Mattress can provide you with both comfort and support. Although, when you initially lie down it can feel a little firm.

I found that once you get into a comfortable position, you sink into the pressure points which keep your spine aligned.

One downside is that the mattress does take a little while to bounce back to its original shape so it wouldn’t be a top recommendation for combination sleepers, like myself, but it does adjust well to every position.

This mattress is suitable for those who share a bed because it has great motion isolation so you won’t feel like you’re moving every time they move.

It also has edge-to-edge support – no matter where you sleep on the mattress, you will feel supported.

What we like about the Simba Hybrid Pro Mattress

There's a lot to love about this mattress but we have narrowed it down to a few of our favourite features. We will go into more detail about why they have made it to our top advantages. Here's our selection:

What we didn't like about the Simba Hybrid Pro Mattress

So, we've mentioned the things we like about the mattress but we probably should talk about the things we weren't that keen on. All-in-all it's a good mattress but there could be some improvements that could make you consider the Hybrid Luxe instead. Here they are:

Simba's customer service and company information

Delivery – When you order from Simba, you can get free delivery the next day or you can choose another day that suits you. Throughout the delivery process, you’re kept updated with the delivery date, time slot and when your driver is nearby.

Payment – PayPal and standard card payments are accepted. There's the option to split the cost of the mattress using Klarna, DivideBuy or Splitit. Make sure you look at their specific terms.

Online customer service – If you need to speak to someone to get help, on their website there’s a chatbot that can answer a selection of questions but there’s no live online chat. You’ll find a page of FAQs or you can fill in a form and get an email response.

Check the alternatives to this mattress

If you don’t find this mattress interesting or you don't like it after your sleep trial, we might have something else in store for you. Here's an alternative option to consider.

Simba Hybrid mattress

If you’re not in the mood for the Pro, maybe the earlier version of this mattress might be the one for you. This is a five-layered mattress, only missing an extra Aerocoil spring layer and a natural wool temperature-regulating layer.

With that in mind, it is still quite comfortable and pleasant to sleep on, but it isn't as cool and breathable as the Pro. And if you're a hot sleeper, that could be a noticeable step-down.

But if you just want a nice, durable mattress that can keep you comfortable, you should be more than fine!

So, if you want to sleep on a premium mattress and see why Simba is one of the best in the game but don't feel like splurging too much money right off the bat, the Simba Hybrid mattress is a very solid pick. Plus, you'll get a decent trial anyway, so you can still change your mind!

Take a look at our in-depth Simba Hybrid Mattress review.

Consider the Simba Hybrid pillow if you are buying this mattress

Product image of Simba hybrid pillow

If you do decide to get this Simba mattress, you might want to add another Simba family member to the mix. The Simba Hybrid pillow is a great addition to any bed.

It is a fully customisable and adjustable pillow, designed in a way that you won’t ever have to turn it to the cool side again.

The pillow case is “powered” by Simba Stratos technology for improved temperature regulation, and the inside of the pillow is stuffed with Nanocubes – small, open-cell memory foam cubes – that you can add or remove to find the desired thickness and firmness of your pillow.

So, if you're a side or back sleeper, you should be sleeping like a champ! However, even though it's adjustable, stomach sleepers might need a flatter pillow.

What makes this product better than some other similar ones?

If we were to compare Simba Hybrid Pro to the rest of the mattresses from the same category that are similar to it, whether in price or performance, we'd say that what makes our mattress special is its remarkable durability.

Simba Sleep is known for making very durable products, and once again – they did not disappoint. It is the perfect mattress that has a fantastic support layer, outstanding edge support, breathable sleep surface, titanium Aerocoil springs, great heat regulation and a free trial period! The most advanced mattress ever with a unique patented structure!

Is the Simba Hybrid Essential Mattress eco-friendly or sustainable?

TSA reviewer lifting the Simba Hybrid Pro mattress

Simba is doing its bit for you and the environment. You get a 200-night trial to try out the mattress to see if it’s the one for you.

On top of this, you have a 10-year guarantee so you can feel confident that it will last you for years to come.

As for the environment, all deliveries from Simba are 100% carbon neutral and they aim to be Net Zero by 2030.

They even have a mattress recycling service to reduce wastage by taking away your old mattress for an extra £40.

As well as this, they've used 100% recyclable materials to create the Simba Hybrid Pro Mattress and used 62% less foam which makes a huge difference.

Included in this is sustainably sourced wool and their ReGen foam that is made from recycled surplus foam.

How did we test the product?

Here's exactly how we test our products. This allows us to be honest about how we come to our final opinion and the experience we had when trying it out. All the products we review go through these tests:

When it comes to the Simba's Pro Mattress, in particular, these are the more specific tests conducted to gauge its quality and practicality:

Overall impressions of the product after the testing

Image of a TSA reviewer looking at the Simba Hybrid Pro mattress

When taking the Hybrid Pro mattress out of the box, I noticed a leaflet was included. It has important information on it with a QR code that links to the Simba website. You’ll find details from unboxing to recycling packaging, to care instructions.

As for the mattress itself, there’s a zip around the blue piping detailing that removes the top cover. It completely unzips which makes it easy to wash. Having this extra top cover acts as a mattress protector so there shouldn’t be any need to clean the actual mattress.

Another practical design feature is the two vertical handles that are on both long sides of the mattress. Rotation of the Hybrid Pro every few months is made much more manageable.

We need to mention how soft and gentle the cover is on your skin which is so important for no irritation and a comfortable night’s sleep.

Simba mattresses use Simbatex foam in their layers and they claim that this makes it 30x more breathable than memory foam, but is it actually noticeable?

Well, when I tried out the mattress I could feel that it was cool to the touch and this was thanks to the additional British Wool layer, under the cover, which naturally regulates temperature. The layer below is the graphite-infused Simbatex layer that uses open-cell technology to allow for airflow, therefore it is extremely breathable.

This mattress is worth taking a look at, but in particular, for those who share a bed or are hot sleepers. You’ll have an undisturbed sleep without feeling movement from your partner or experiencing night sweats. It’s the natural upgrade from the Simba Hybrid and a larger step up from the Simba Essential.

FAQs about your new Simba Hybrid Pro Mattress

In the end, we thought we’d wrap things up by answering some questions about Simba Hybrid Pro mattress.

Is the Simba Pro Mattress firm?

Simba Hybrid Pro is a medium-firm mattress rated at 7.5 out of 10 on the firmness scale.

What bed base can I use for this mattress?

You can use any bed base for Simba Hybrid Pro; although, we will recommend you use a solid base over the slatted one if you prefer a slightly firmer feel to your mattress.

Does this mattress come with a mattress protector?

No. This mattress does not come with a mattress protector. That is something you will have to buy separately if you wish to use it. The removable cover doubles up as a mattress protector though.

What type of sleepers should go for this mattress?

Simba Hybrid Pro should be a good fit for all types of sleepers, though we noticed that many people suffering from back pain praised this Simba mattress.

What is the difference between Simba Hybrid and Hybrid Pro?

From the Simba Hybrid to the Hybrid Pro Mattress, they have doubled the Aerocoil micro springs from one layer to two layers. As for temperature regulation, they have introduced an extra top wool layer for this purpose. However, there are similarities too – including thirteen zones of support, a breathable cover and their Simbatex foam layer.

Does this mattress get softer over time?

Like every other mattress, Simba Hybrid Pro will degrade over time, but considering the quality of the mattress – this shouldn’t happen for a very long time, especially considering the quality of memory foam layers.

How do I clean my mattress?

You may clean your mattress with a damp cloth and some warm water if you happen to stain it. Just make sure to keep your mattress dry at all times.

Does Simba offer non-contact delivery?

Yes, you can order your product with no contact delivery. The product will be delivered to your door.

Do I get a full refund if I don't like the product?

Yes, you do get a full refund in case you are not satisfied with the product.
