Who is this Product for?

Recyclable Simba GO hybrid mattress with exposed layers- render

The Simba GO hybrid mattress is honestly remarkable when it comes to build quality. Not only does it offer amazing support without sacrificing comfort, but it does so while using sustainable and eco-friendly materials! Not to mention that it's also highly breathable and hypoallergenic. So, it's the perfect choice for:

  • Hot sleepers
  • Sleepers with allergies
  • Environmentally-conscious sleepers
  • Sleepers looking for extra support
  • Sleepers looking for extra comfort

What do we use this product for?

Just like with any high-end hybrid mattress, the Simba GO offers equal part support and comfort. And through its rather innovative design, the Simba mattress also helps with allergies, dust mites, and overheating. So, we use this hybrid mattress for:

Table of Contents

Features you should know about the Simba GO Hybrid mattress 

Now that we've established the general strengths of the Simba hybrid, it's time to go more in-depth. So, we're going to look at every single feature that the Simba GO hybrid mattress offers and hopefully determine whether it's the perfect hybrid mattress for you!

An image of the layers of the Simba GO hybrid mattress
Non-removable organic & breathable cotton cover

Just like in any Simba hybrid mattress review we've done so far, let's start things off with the cover, as that's the layer you'll be in direct contact with. And for the most part, it's rather revolutionary.

The cover is made from pure, organic cotton that's very soft to the touch and even offers exceptional breathability. Already this makes the mattress a lot more comfortable and assures hot sleepers that they won't feel like they're sleeping in a furnace. Plus, the cotton is sourced in accordance with the Global Organic Textile Standard, meaning that everything is done by the book.

However, the cover being non-removable is a slight stain on an otherwise flawless design. After all, this means that maintenance takes a bit more effort than just throwing the covers into a washing machine. Rather you have to spot-clean the mattress.

But it isn't the end of the world. For one, the mattress doesn't actually utilise memory foam so the margin for error when spot cleaning isn't too strict. And you can always get a mattress protector to keep things rather safe.

Recycled Simba Renew layer

If you're an environmentally conscious individual, this layer will make the Simba Go mattress stand out prominently amongst all other hybrid mattresses. After all, it's not every day that you see a mattress layer being made from recycled PET bottles.

And just like with the mattress cover, everything was done up to code, with the entire process measuring up to the Global Recycled Standard. So, if you had any worries or concerns about the manufacturing process, this should give you some peace of mind.

We'll admit, reading that something is made from recycled bottles usually doesn't paint a very comfortable picture, but don't you worry. The layer itself doesn't have any plastic but rather siliconised fibres. And not only are these fibres rather comfortable, but they also further promote airflow throughout the entire mattress.

And if that wasn't good enough already, this layer also holds hypoallergenic properties and discourages dust mites. So, with this one layer, you get sustainability, hypoallergenic air flow, and comfort – that's a bit more than what you get with your standard memory foam layer, now isn't it?

GOLS Organic latex

If we had to single out one layer that makes this Simba hybrid mattress a top-tier product, it'd be the latex layer. This is because natural latex is like the upgraded form of memory foam.
It offers the same kind of pressure relief and support as memory foam, but it does it more efficiently. In particular, it responds to pressure a lot more quickly. So, while it might take a minute or two for the memory foam to adapt to your body, natural latex will almost immediately offer you next-level comfort.

And that's not all! One of the main drawbacks of memory foam is that it can lead to overheating, as memory foam usually doesn't make for a breathable sleep surface. Natural latex on the other hand organically bolsters airflow and temperature control.

But Simba still wasn't done, as they used perforated natural latex. In layman's terms, this means that the natural latex, which is already breathable, has tiny holes within it that allow air to travel even more efficiently. We'd say that's a pretty sweet deal!

Of course, there are small drawbacks. For one, the natural latex makes this Simba hybrid anything but an affordable mattress. Plus, just like memory foam, natural latex does have slight off-gassing issues. But don't worry, everything is done up to the Global Organic Latex Standard, so the smell isn't any indication of dangerous chemicals or anything like that.

Aerocoil spring layer with 2,000 conical springs

You can't have a Simba hybrid mattress without a spring layer, so that's what we're looking into next. And straight off the bat, you might notice that the Simba GO has a significantly larger number of springs than most spring mattresses – with most standard models having between 1000 and 1500.

However, this doesn't necessarily mean that the Simba GO is a firm mattress – owing to the latex comfort layer we just discussed. Rather, the 2000 25mm coils help support your body while you sleep. So, you get the comfort of a memory foam mattress and the utility of pocket springs – what more could you want?

Plus, this layer covers the entire mattress, meaning that even the corners are rather firm and stable. And if you sleep with a partner, or tend to roll around in your sleep, good edge support is a must! Not to mention that it also increases effective mattress size (since you can sleep at the very edge), making even a Double mattress seem rather spacious.

Lastly, since the springs are also pocketed, you shouldn't have any motion transfer issues either, as the springs independently react and support your weight. Rather impressive for something that's only 25mm tall, now isn't it?

Zoned Supportcore Base

If you're somehow still wondering “Is the Simba hybrid mattress good?”, this ought to sway your opinion. Remember how we just talked about the 2000 Aerocoil pocket springs? Maybe you even questioned whether 25mm was enough to truly support your weight.

Well, that's where the zoned Supportcore base layer comes in. This is a layer of 900 steel barrel springs that were strategically placed to offer support to your hips and shoulders. This is quite the selling pitch for side sleepers, but it's honestly good for everyone, regardless of their sleeping position.

After all, zoned stress and pain relief means that you get the benefits from something like an orthopaedic mattress, while also maintaining comfort. So, if you have an old mattress that has long lost its firmness, the Simba hybrid mattress is bound to make you feel reborn.

3D mesh for increased breathability

Lastly, we reach the very bottom of this green, organic mattress. Having a mesh base isn't unheard of for memory foam mattresses, but it's definitely a welcomed sight.

By now you might have realised that every layer in this Simba hybrid mattress offers breathability in one way or another. And yet, Simba was so dedicated that even the very bottom of the mattress had to be breathable. Needless to say, it's almost impressive if someone manages to have overheating issues while sleeping on this large, very inviting mattress.

Another frequent theme in this Simba mattress review is sustainability. And again, Simba ran the extra mile and made this mesh out of recycled and new fibres. So, your Simba sleep is as eco-friendly as they come.

100% recyclable materials

For those of you who skimmed through this Simba mattress review, it's important to point out how eco-friendly the Simba GO hybrid mattress is. Simba already has tons of green initiatives but this mattress takes it to a new level.

The Simba Renew layer is made from up to 75% recycled PET bottles, the mattress base is also made from a mix of recyclable and new fibres, and the entirety of the mattress itself can be recycled after you're done using it.

So, if you're environmentally conscious and don't want to buy a super king memory foam mattress because of concerns about where it will end up or how it will affect mother nature – the Simba GO hybrid mattress is quite frankly the perfect mattress for you.

Carbon Neutral Delivery

If recycling wasn't good enough on its own, Simba also offers carbon-neutral delivery. By this point we hopefully all know how important it is to cut down on carbon emissions, so this decision by Simba is more than welcomed.

Standard delivery is also free, which is a nice bonus, and you can have the mattress delivered to a room of your choosing and with zero contact. On top of all this, just in case you weren't sold on the customer service yet, Simba also throws in a mattress removal option. And let's just say that this is quite handy if you have an old, heavy super king-size mattress sitting in your bedroom.

200-night trial & 10 years warranty

Although this isn't the longest trial you can find, as some sleeping brands offer 1+ years, nor the longest warranty, with Dreamcloud offering a lifetime warranty, it's still a good selling point.

After all, this mattress carries the same price tag as the Simba Hybrid Luxe – meaning that it's anything but cheap. So, having the peace of mind that it's going to say around for at least a decade, providing you take care of it, is a nice addition.

And if you're the type to get cold feet, 200 nights is more than enough to experience first-hand why this mattress is worth keeping around.

Review of the Simba GO Hybrid mattress

Close up shot of the Simba GO hybrid mattress pocket springs

This mattress isn't for everyone. It's very expensive but also one of the highest-quality mattresses you'll find on the market. It's a lot more breathable than any memory foam mattress, has zoned support for your hips and shoulders, and offers exceptional comfort.

On top of all this, it's the greenest mattress we've reviewed thus far, with most of the materials being recycled, and it offers natural protection from most allergens and dust mites. So, it's like your bed frame is housing a protective barrier from all sniffling and coughing.

This lovely mattress does come with some downsides though, as the cover is not removable and there might be slight off-gassing upon first opening up the product. However, that's nothing a mattress protector and an open window can't fix.

And while the mattress is very expensive, Simba does offer up some rather enticing payment options where you can pay it off over the span of 4 years. So, if you're willing to make a long-term commitment but don't have that much cash up front, this is an excellent option.

What we like about the Simba GO Hybrid mattress 

In this section of the Simba hybrid mattress review, we'd like to quickly go over our favourite aspects of the GO model. So, if you're still on the fence, this should help make up your mind.

What we didn’t like about the Simba GO Hybrid mattress 

On the other hand, this Simba hybrid mattress review would feel a bit off if we only talked about the positives. So, here are a few things that we didn't really like about the Simba GO.

The common problems with the Simba GO Hybrid mattress  & how to solve them

Since this Simba hybrid mattress is nearly flawless when it comes to its build quality, the only issue you're likely to face is actually paying it off. And while Simba has detailed explanations on their site, this is just the TLDR.

Simba has partnered up with two established brands for finance options: DivideBy and SplitIt. If you choose to pay the mattress off within 12 months, there's no interest rate and you pay the exact same sum as when you pay upfront – which is quite the benefit.

However, if money is a bit tight currently, you can choose to pay the mattress off over the span of up to 48 months. However, in this case, the price will be higher than if you bought it upfront.

So, pick whichever option works best for you. And make sure to read the information on their site carefully, as even something like PayPal credit is acceptable in some cases!

Check the alternatives to the Simba GO Hybrid Mattress

It's always good to keep your options open. So, if you really want a Simba hybrid mattress but the Simba GO just doesn't tickle your fancy, don't worry! After all, you can get a different Simba hybrid mattress that comes with the same quality plus some added perks. Although it does also come in the same price range as well.

Simba Hybrid Luxe

a product image of simba hybrid luxe mattress

If you gave a mattress manufacturer an infinite budget and the task of crafting the perfect mattress, we think it would look something like the Simba Hybrid Luxe. With a whopping 10 layers of meticulously crafted comfort, this Simba hybrid leaves nothing to be desired.

With two Aerocoil comfort layers and a carbon steel layer further down, this mattress offers unparalleled support. On top of that, the Simba pure foam serves as great cushioning, making your sleeping experience much more comfortable.

And if the high-definition foam layer still wasn't enough to make you feel snug, they threw in a bamboo wool layer for good measure.

Overall, it's like you took the Simba hybrid Pro mattress and made every feature better. So, if you ever wanted to buy Simba mattresses, this is one of the best picks on the market.

What makes this product better than some other similar ones?

A woman's hands holding a plant

As we've seen with the Simba Hybrid Luxe mattress, you can get a mattress that's of comparable quality to the Simba GO. However, none of the Simba mattresses can really compete with the Simba GO in terms of sustainability.

We've mentioned this a few times already but the Simba GO is in a league of its own when it comes to sustainability and green initiatives. Not only is the mattress itself completely recyclable, but some layers are even made from recycled products.

Not only that, but all the materials used have some sort of accreditation that showcases they were sourced in an ethical and sustainable way. So, if getting a good night's sleep means having a clear environmental conscious, the Simba GO is arguably the best in the business.

Is the Simba GO Hybrid mattress eco-friendly or sustainable?

Yes, a million times yes. When it comes to sustainability, the Simba GO is nothing short of the golden standard. Not only are two of its layers made in part from recycled materials, but the mattress itself is completely recyclable. Plus, Simba offers carbon-neutral delivery as well as GOTS and GOLS certifications.

So, we really don't know what else Simba could possibly do to make the Simba GO more sustainable than it already is.

How did we test the product?

How we tested the Simba GO hybrid mattress

Now that we've talked about the Simba hybrid mattress and all of its many features, it's time to explain exactly how we tested the mattress when conducting our research.

On a very general level, all products go through the following tests:

  • Visual inspection
  • Hands-on inspection
  • Measured tests

When it comes to the Simba hybrid mattress, in particular, these are the exact tests we conducted when gauging its quality:

Overall impressions of the product after the testing

Overall, we have nothing but praise for the Simba GO. We knew that reviewing a Simba hybrid mattress was bound to be a pleasant experience, but the Simba GO still managed to blow away our expectations.

To say the mattress was comfortable wouldn't be doing it justice. The natural latex offers just the right amount of cushioning to make you feel snug while the two spring layers offer much-needed support and stress relief. At least that was our experience when testing the Simba GO.

We will admit that the mattress is firmly on the expensive side of things, with only the Simba Hybrid Luxe being in the same ballpark, but Simba does offer financial aid – so it shouldn't be an immediate deal-breaker.

You might also want to get a mattress protector, especially if you're accident-prone or have children, as spot cleaning is a bit more time-consuming than just chucking the covers into a washing machine.
