When it comes to hybrid mattresses, a Simba is a household name in the mattress industry. Any Simba mattress might just transform your bedroom for the better, but just to be sure, we wanted to find out can Simba Hybrid do the same. So, let us find out together.

Who is the Simba Hybrid mattress for?

Being the most affordable out of the three in Simba's Hybrid series, Simba Hybrid might just be the best out of three – all things considered. Compared to the Pro or the Luxe, this Simba mattress is much better suited for an average consumer.

It is not too expensive, it isn't too complex in its nature, and what's more important – it is medium-firm. For those looking for a good balance of support and comfort, this is a great product that will last for many years.

Aside from being medium-firm and fairly suitable for all sleeping positions, Simba Hybrid is also excellent for both solo sleepers and couples, people with bad backs and restless sleepers. However, the biggest praise comes from the side sleepers who enjoy a bit of extra cushioning and support around the core areas.

We guess what we're trying to say is – this mattress could just be for everyone. It is just a matter of personal preference – but in general, everyone should be good with this product. Also, hot sleepers who want a cooling pillow will absolutely love it!

What do we use this product for?

This mattress brings you the best of both worlds – the support of pocket springs and the comfort of memory foam mattresses.

As is often the case with Simba mattresses, you'd use this one to finally get a good night's sleep. You see, this is not your “most advanced mattress”, or anything of sorts, but what it is, is a very good mattress that can help you sleep better, and at the end of the day (pun intended) that is all that matters.

What's even better is, this bed-in-a-box Simba mattress comes in nine different sizes, which loosely translates to – you can pretty much use this mattress however you want. Get it for your kids, your guests or your master bedroom – it'll get the job done.

Features you should know about the Simba Hybrid mattress

Since this is a hybrid, you are already aware that this one comes with pocket springs and memory foam, but we want you to know more than that. Now, let's take a dive into this mattress – Simba Hybrid.

5-layer construction

Being the most affordable out of the three Simba mattresses in the Hybrid series, this one is also the least complex in its nature. However, we wouldn't call the 5-layer construction of the Simba Hybrid simple, so let's take a good look at it.

The first of five layers is the sleep surface – a 100% polyester, hypoallergenic knitted cover. Underneath it, we have an open-cell Simbatex layer, followed by Simba’s unique patented titanium Aerocoil spring-comfort layer, which is then followed by the high-definition edge support layer resting on the multi-zoned foam base.

Simba-hybrid-mattress-layers

Open-Cell Graphite-infused Simbatex layer

As we all know, mattresses with this much foam in them are notorious for being overly hot and clammy once the summer hits. That is why Simba decided to develop a new type of foam to tackle this issue.

Simbatex is an open-cell graphite-infused foam that is specially designed to move the heat away from the body and prevent overheating in two ways. One – open-cell foam is far less dense than regular foam, which means there’s more room for airflow. Two-graphite is a well-known thermal conductor added to the mix to draw the heat away.

And, while this piece of foam does what it is designed to do, there’s just not enough of it to make a major difference, so don’t expect a very cool sleeping surface out of this mattress. It’s passable, but nothing more than that.

Titanium Aerocoil spring system

Underneath the open-cell memory foam layer lies up to 2500 25 mm conical pocket Aerocoil springs, made in the UK with titanium alloy.

As you can see, this is not your regular pocket sprung memory foam hybrid. These springs aren't full-sized, but each of the 2500 springs is individually enclosed in a polyester pocket, the same as any other pocket spring.

Simba promises these will help you experience gravity-defying comfort and the best sleep of your life, and from what we’ve seen – that might be stretching it. They do provide a great level of comfort but considering they make up 10% of the entire mattress, we’re not so sure they’re that much of a difference maker. They’re perfectly made thought. Brilliant craftsmanship.

HD Edge-to-edge support

Between the HD support base and the Aerocoil pocket sprung layer, we have a high-density foam edge support layer. To get the most out of these mini pocket springs, you need a firmer base to support them, and a grooved Simba-pure support base isn’t going to cut it, which is why this layer is here.

That, and to provide a little bit of extra support around the edges, as you can tell by the name.

Zoned Simba-Pure support base

The base of this entire mattress is supported by the high-density Sima-pure support layer. The zoned Simba-pure support base has 5 different zones for support. This is achieved by grooving out the base in strategic places to offer the right support and pressure relief where it is needed. This way, regardless of your sleeping position, you will always be properly supported and your spine will be correctly aligned.

CertiPur certificate

Another thing to know about this bed-in-a-box is that all the foams used in the manufacturing of this mattress are CertiPUR certified. Loosely translated, this means that there are no harmful chemicals inside this mattress, so you may feel free to sleep on it for as long as you want. Standard practice at this point for every reputable mattress manufacturer.

Free of TCPP, phosphate, biocides, pollutants and parabens

Simba wanted to create a perfect mattress and lower their carbon emissions, so not only did they do this, but they also made sure that their mattress don't contain TCPP, phosphate, parabens, biocides and other pollutants.

Trial period, warranty, shipping and refunds

Simba Sleep makes shopping a much easier and stress-free, pleasant experience. Purchasing is risk-free and trial periods go up to a year. In this case, you also get a 10-year warranty.

As for shipping, you can choose between free and paid shipping, depending on your needs. Shipping rarely takes more than three days and that holds true for both free and paid shipping.

What’s also very nice to see is that every delivery is carbon-neutral, which is a big plus in our book. As for refunds – they’re free of charge and stress.

Reviewing the Simba Hybrid mattress

Product image of the Simba Hybrid mattress

And now, for the cherry on the cake – the review of the Simba Hybrid.

As you could tell so far, this is without a doubt an excellent mattress, which is what you would expect out of a Simba mattress. However, as you know, we wouldn't just make bold statements, so let's take a look at how this Simba mattress has performed.

Let's start with the essentials – support and comfort. We've learned earlier that a Simba mattress will rarely leave you asking for more when it comes to support and comfort, and once again, that proves to be true. Support is quite good with this one, and we're not just talking about the middle of the mattress but around the edges, too.

Now, keep in mind, support and firmness aren't the same, but they're connected. So, if you're a bit on the heavier side, you might not find this mattress very supportive.

And, we do know that comfort is a subjective thing, but as far as we're concerned, Simba Hybrid is objectively comfortable.

On the other side of things, despite their best efforts to keep this Simba mattress cool and breathable, they couldn't do it. There's just too much foam in this one, and if it's very hot in the room you're sleeping in – it's going to be hot in bed, too.

Simba Hybrid Luxe

a product image of simba hybrid luxe mattress

Simba Hybrid Luxe is inarguably the best mattress Simba has ever made. It is a 10-layer hybrid, medium-firm mattress that could many other mattresses to shame.

Everything about this mattress is luxurious, beginning with its 10-layer structure, including a zip-off cover and the premium materials used to build it. Also, we can't forget about the exquisite craftsmanship, excellent design and even better performance.

Naturally, this level of luxury and quality comes at a cost, since the Luxe is one of the most expensive commercially made mattresses in the UK. Check the comparison tool to get the direct comparison between this mattress and the one we are reviewing.

Simba Hybrid Pro

Simba Hybrid Pro

Simba Hybrid Pro is a step-up from our reviewee in several ways.First of all, Hybrid Pro comes with up to 5000 pocket springs, which is twice the amount the Hybrid comes with. But, that's not the only difference.

This one also has 7, instead of 5 layers. One of the extra two layers found in this one is the extra Aerocoil layer, but the other one is the natural wool layer added for improved temperature regulation.

All in all, the Hybrid Pro is quite similar to Hybrid, only it's a little bit thicker and a bit more supportive.

Consider Simba Pillow if you are buying a Simba Hybrid mattress

Product image of Simba hybrid pillow

Simba Hybrid pillow is a fully adjustable, memory foam pillow that if given a chance could probably change your life for the better. Instead of being filled with a single memory foam insert, the insides of this pillow are filled with soft Nanocubes – small, memory foam cubes that you add or remove from your new pillow to adjust its loft.

The cover of this one is also quite impressive. It is enriched with Simba active cooling technology called Stratos, so you won't have to worry about turning the pillow over to the cool side ever again.

Not only will you get extra Nanocubes once you purchase the pillow, but you'll also probably take a lot of Nanocubes out in the first place, leaving you with spares that you could use to keep your pillow perfect for a very long time.

Advantages

What makes this product better than some other similar ones?

Why should you replace your old mattress with this one? Well, for starters, Simba Hybrid is one of the mattresses that you are going to sleep on for a very long time. As long as you rotate your mattress regularly, you should have no problem outlasting the 10-year warranty you'll get once you purchase this mattress.

200-night trial with 10-year warranty

Also, even if by some chance you don’t end up enjoying it, you will have a full year to really take your time testing it. If you don’t like it – you’ll get a full refund. In other words, this is an excellent, risk-free investment.

On top of that, you will also get a 10-year warranty, so you can rest assured Simba has got your back for at least a decade, both literally and figuratively.

And, as far as risk-free investments go – we can’t really say we know of a better one. You have absolutely nothing to lose. Except maybe a backache, but we’re willing to bet you’d be willing to do that.

How did we test the product?

As you know, before we write these reviews, we first have to test the product and that whole journey starts with placing an order. The good news is, UK standard delivery also means free delivery, which means we only had to wait for the delivery date and we could be on our way to writing this review.

Also, we can't forget to mention, but if you want to get rid of your existing mattress, Simba also offers a free collection, which we used on several occasions. Outside of UK, different delivery charges apply, and for further information on it, we suggest you check Simba's website.

The delivery of the product

Now, let's talk about the testing process. As you probably know this bed-in-a-box is delivered vacuum packed, so the first thing we do upon receiving our new mattress is open up the box and inspect the mattress for any defects. Fortunately, none were present in this case, so we could set up our bed and begin our tests.

Testing with different bases, positions and weights

The way we do these is by having all members of our team spend ten days with the mattress. During those ten days, we'd test the mattress in different conditions. For example, we'd test the mattress both on a solid and a slatted base, to see if it will feel softer on either of them. We'd also adjust the room temperature, try out different sleeping positions, do the roller and the kettlebell test and so on.

All of this allows us to paint a very clear, objective picture of what can this mattress do, and we sure hope we manage to do that.
