Simba mattress composition

The Simba mattress is a hybrid pocket-sprung foam mattress that combines high-quality pocket springs with multiple layers of foam.

The layers of the Simba Hybrid (excluding covers) are:

  • Open-cell, graphite-infused Simbatex foam
  • 2000 Aerocoil conical pocket springs across 13 zones
  • CertiPur stability layer
  • No roll-off SupportCore base with up to 1000 barrel springs

Simba advertises the Hybrid as a 5-layer mattress, which includes the mattress's breathable top cover.

We look at the mattress cover in more detail further down. 👇

For now, let's look at the actual mattress layers in a bit more detail.


Simba mattress layers

Simba Hybrid mattress layers

We'll look at the cover in more detail further down.

For now, here are the actual mattress foam and spring layers/

1. Top comfort layer of graphite-infused Simbatex open-cell polyfoam

The top layer of the mattress is made from a soft, open-cell polyfoam called Simbatex.

This layer, with its open-cell structure, is much more breathable than closed-cell memory foam and allows for greater airflow. 💨

It also includes graphite, which further enhances the foam's cooling properties.

2. A layer of Aerocoil pocket springs

Up to 2000 mini pocket springs (2.5 cm in height) are positioned right under the comfort layer, providing bounce, high body adaptability, and even pressure distribution.

Mini pocket springs tend to offer better body adaptability than full-size springs do.

These springs are conical, allowing them to compress a fair bit. 🌀

The individual coils are enclosed in polyester fabric pockets, which increases motion isolation and protects the surrounding foams.

The pocket springs are hidden within the mattress so that you won't feel any discomfort.

3. A stability layer

A CertiPur foam layer acts as a transitional and extra stability layer between the Aerocoil spring layer and the SupportCore base layer.

In a previous version, this was made from high-density Simba-Pure foam with Edge Lift Technology and, before that, this layer combined memory foam with latex foam.

This is why Simba used to be called a pocket sprung memory foam mattress.

Since memory foam retains more heat than other types of foam, Simba changed the composition of their mattress to be more breathable overall.

4. SupportCore base layer

The base layer of the Simba Hybrid is made of up to 1000 durable barrel springs.

These provide firm edge support, meaning you can enjoy the full width of the mattress at all times.

The additional springs also allow for better airflow, again enhancing the overall breathability of the mattress.


Simba mattress contour zones
The grooves in the base foam act as contour zones, enhancing spinal alignment.

Who is the Simba Hybrid most suitable for?

We really enjoyed sleeping on the Simba Hybrid & would highly recommend it.

But, no mattress will be suitable for everyone.

You'll love the Simba mattress if you:

  • Are of light or average weight.
  • Enjoy sleeping on your back or side.
  • Are looking for orthopaedic support.
  • Are a heavier sweater.
  • Are a restless sleeper.

But, there are a few drawbacks:

  • The mattress is quite heavy, so it might not suit those with physical difficulties (the mattress has to be turned regularly).
  • The mattress is quite expensive, so it might not be suitable for those on a low budget. We'd suggest looking at the cheaper - but still high quality - Silentnight mattresses instead.

The Simba mattress is excellent - but it can be a bit pricey

Need a recap?

Here is a quick overview of who the mattress is most suitable for - and who it isn't:

Different types of sleepers
The Simba mattress is most suitable for:

Light or average-weight sleepers

Side or back sleepers

People looking for orthopaedic support

Heavier sweaters

Restless sleepers

The Simba mattress is less suitable for:

The elderly or people with physical difficulties

People on a budget

Simba mattress firmness

The Simba Hybrid has been designed as a mattress with medium firmness - and we'd agree. 👌

We've placed it at 6 out of 10 on the Sleep Hero firmness scale, where 1 is the softest and 10 is the firmest.

Some of our test sleepers perceived the mattress as slightly firmer, but this will depend on your body size and weight. ⚖️

We'll go into more detail on this further down.

Simba Hybrid Firmness

Measuring sinkage depths

To do an in-depth Simba mattress review, we've measured how deeply we sank into the foams in different sleeping positions.

This allows us to gauge how the mattress responds to body weight and how much support it gives.

When doing our measurements, we always make sure to take readings at the same place:

  • For example, if sleeping on the stomach, we measure at the stomach.
  • If sleeping on the back and sides, we measure at the shoulders and hips.

This ensures fair and accurate readings.


Simba mattress knee test
We take measurements in different positions to see how firm a mattress is

The values below are based on the body measurements of one of our test sleepers - 182 cm (5 feet and 9 inches) and 72 kg (158 lbs).

Position Depth of sinkage
Lying on the back 6 cm (2.3")
Lying on the side 7 cm (2.7")
Sitting on the edge 9 cm (3.5")
Standing in the middle 16 cm (6.2")

We had multiple other test sleepers who gave similar reports.

As you can see, there is a good amount of sinkage. 👍

This means that the mattress is definitely soft enough to accommodate lighter weight sleepers and adjust to different sleep positions.

In the side position, for example, there is more sinkage than in the back position.

This will ensure that the hips and shoulders sink in a little deeper than the rest of the body, providing optimal spinal alignment.


Simba mattress side sleeper
Side sleepers will sink in more deeply in the shoulder and hip areas

But, the mattress still allows for even weight distribution.

When standing on the mattress, a lot of weight is placed in one position and the foams sink in very deeply.

You can see this quite clearly in the image below. 👇

Of course, you're unlikely to ever stand on your mattress, but measuring this helps assess the bed.


Person standing on Simba mattress
You'll sink in quite deeply if you stand on your mattress

When lying on the back, though, the weight is distributed over a larger area.

In turn, the foams only sink in a little to allow for a more comfortable sleep.

If the foams would sink in as deeply when lying on the back as they would when standing or kneeling on the mattress, the mattress would be too soft and would likely cause severe back pain.

Measuring the sinkage depths of the Simba has proven that this is a medium-firm mattress that allows for optimal spinal alignment no matter your sleeping position or body weight.

Firmness-wise, this mattress would be suitable for a wide variety of sleepers.


Simba mattress back sleeper
You'll get good support as a back sleeper

What does sleeping on the Simba Hybrid mattress feel like?

The combination of mini pocket springs and different foam layers allows the Simba Hybrid mattress to highlight the advantages of each of the materials used. ⭐️

Let's illustrate this:

  • The top layer provides a pleasantly soft lying feeling.
  • The conical pocket springs allow for even pressure distribution, eliminating pressure points and easing tension.
  • The SupportCore base enables edge-to-edge support, so you'll feel well-supported no matter where you lie.

This combination makes the Simba Hybrid an overall comfortable yet very supportive mattress that can help relieve orthopaedic concerns.


Simba mattress with test sleeper
Comfortable sleep is just a click away

Optimal support for light and average-weight sleepers

You'll find the Simba Hybrid exceptionally comfortable and supportive if you're lighter or of average build.

All of our test sleepers - regardless of height, weight, or sleeping position - reported that they found the mattress comfortable to sleep on and that it supported their body well throughout.

The mattress was most comfortable when sleeping on the side and sleeping on the back.

In both positions, the mattress manages to offer the perfect mix of support and sinkage.

For example, look at the image of one of our back sleepers below:

Simba mattress back sleeper
The Simba is very comfortable for back sleepers

You can see that the heavier parts of the body sink in a little more deeply, but the rest of the body remains well-supported.

This ensures that the spine remains straight.

Compare that with the image below of our side sleeper:

Simba Hybrid mattress sleeper shoulders
Your shoulders will sink in more deeply

You can clearly see that the shoulders sink in a little more deeply.

This, again, allows the spine to remain straight. 🦴

As an aside, notice how the sleeper's position is affected by the pillow in the above images.
The pillow is too high for the back sleeper as the neck bends up. In contrast, the side sleeper should have a high loft pillow.
Pillows help with creating upper spinal alignment. Read our best pillows article for more information.

Optimal spinal alignment eliminates the risk of lower back pain or a build-up of tension.

Not firm enough for larger builds

Even though the Simba Hybrid is a medium-firm mattress that offers sensational support, it may not be firm enough if you're heavier or of a larger build.

This is because people of a heavier weight often require a firm mattress that can provide enhanced stability and support.

Pure pocket spring mattresses are a good alternative.

You can also consider firmer all-foam or hybrid mattresses, like the Nectar mattress or the Simba Hybrid Luxe.


Simba mattress knee test
Heavier people may not find the mattress firm enough

Excellent edge support

You'll experience excellent edge support on the Simba Mattress Hybrid. 🏅

For our Simba mattress review, we had various people sit and lie near the edges of the mattress.

Everyone remained well-supported.

Often, mattresses (like the Emma Original) are stable and supportive at the core, but this firmness decreases towards the sides of the bed. 🤨

This is not the case with the Simba mattress.

The core layer of high definition Simba-Pure foam features additional Edge Life technology for enhanced edge support to keep the mattress firm no matter where you lie.

This means that you can sit or lie at the end of the mattress quite comfortably without feeling like you're falling off the sides. 🏔

This is excellent news if you like to make use of the entire width of your mattress or if you're sharing your bed with a partner.


Simba mattress edge support

Sitting on the Simba mattress

Good for restless sleepers

Many bed-in-a-box mattresses rely on memory foam, which can be challenging to move around on. 💃

This is because memory foam has that distinctive memory imprint.

The foam moulds to the shape of your body and needs some time to "jump back into position" when you have moved.

Look at the images below that demonstrate the memory effect:

Memory foam with hand

Memory foam imprint

You can see that an imprint of the hand remains.

We did a similar pressure test with the Simba mattress.

Look at the images below:

Simba mattress pressure test

Simba mattress pressure test 2

You can see how beautifully the foams jump back into position.

The Simba Hybrid mattress will support you very well and give you that body-contouring support, but it won't give you that "sinking into the mattress" feeling.

This means you can toss and turn as you wish. 🥳

This also makes the mattress particularly good for restless sleepers.

Orthopaedic support

The above images demonstrate how well the foams bounce back, but they also indicate how supportive the mattress is.

The first image shows how deeply the stick is pushed in, but only one part of the mattress is affected. 🥊

This demonstrates that the Simba mattress has very high point elasticity.

It will mould to your body perfectly where needed, but the rest of the mattress will remain unaffected.

This means that you will receive soft cushioning & contouring exactly where required, while the rest of the mattress will remain supportive.


Simba mattress foams
The Simba mattress is very supportive

Excellent temperature regulation

The Simba mattress was designed with cooling in mind. 🆒

It has these cooling properties:

  • A knitted cover that enhances breathability.
  • Open-celled Simbatex foam with cooling graphite.
  • Pocket springs with natural ventilation channels, which increases airflow.

These features allow for improved breathability and enable air to flow freely through the mattress. 💨

This keeps you cool and comfortable all night long.

You won't feel hot and clammy on the Simba Hybrid, even on a hot summer's night. 🍉


Our temperature tests

Simba mattress temperature test

To better demonstrate the temperature regulation of the mattress for our Simba Hybrid review, we took some measurements.

Here, you'll see the results.

The image demonstrates that heat is stored exactly where the test sleeper lies.

But the rest of the mattress remains completely temperature neutral. 👍

As soon as our test sleeper moved to a different position, the previously heated area cooled down.

This proves that the mattress doesn't store excessive heat - and that you can remain cool and comfortable all night long.

Is the Simba Hybrid mattress good for couples?

Whether or not a mattress is good for couples depends mainly on its degree of motion transfer.

Motion transfer refers to the movement that is carried through the mattress.

If a mattress has low motion transfer, it means that movements are absorbed and dampened - and you won't be disturbed by your partner's movements at night.

Simba mattress motion transfer

The previous version of the Simba mattress had exceptionally low motion transfer.

But the newer version - which focuses much more on enhanced breathability - does allow some motion to flow.

It won't be as noticeable as with a mattress like the GhostBed - but also not as still as pure memory foam mattresses.

You shouldn't be disturbed by your partner too much, but you may feel some movement now and then.

For this reason, we'd recommend opting for larger mattresses sizes, like the Simba Hybrid king-size or the Simba Hybrid super-king-size mattress. 👑

These larger sizes ensure that there's enough space between you and your partner, should you wish to have it.

Snuggling is always allowed, of course.


Simba mattress cover

The Simba mattress cover has been designed to be hypoallergenic and allow for greater airflow.

It is made of 100% polyester and includes grey sides and a white hand-knitted top cover. 🧶

We really liked how soft and cuddly the cover was!

The Simba cover also has four side carrying handles, which makes moving and transporting the mattress easier.

Only the single-size and small double mattresses don't have the handles.


Simba mattress cover
You can remove the cover.

Removable and washable top cover

You can remove and wash the top cover of the Simba Hybrid mattress cover at 40℃.

Tumble-drying is not recommended.

We love mattresses with removable and machine-washable covers as this is great for hygienic purposes. 🧼

The grey base fabric of the cover can be cleaned with a soft, damp cloth. 🧽

But to further safeguard your mattress, we highly recommend using a waterproof mattress protector.

Mattress protectors create an additional layer between your bedding and your mattress to protect against stains, spills, moisture, dirt, and bacteria.

The Simba mattress protector is great.

Can Simba remove my old mattress?

Simba offers a removal service, where they collect your old mattress when they deliver the new one.

Simply select the mattress removal option at checkout. 👩‍💻

How do I unpack my Simba mattress?

Your new mattress is super easy to unpack:

The mattress will expand within a few hours

Does the Simba mattress smell?

Our mattress didn't smell when we unpacked it, but you may notice a slight smell when you first unpack it.

This is called off-gassing, and it's totally normal with bed-in-a-box mattresses.

We'd recommend unpacking your mattress in a well-ventilated room and letting it air out until the smell dissipates. 🏡

Which bed base can I use for my Simba mattress?

The Simba mattress can be placed on top of any bed base, including adjustable bases, slatted frames, divan bases, or box springs.

If you're using a slatted bed frame, ensure that the slats are no greater than 7.5 cm (3 inches) apart so that your mattress is supported correctly.


Simba mattress trial period

Simba mattresses come with a risk-free 200-day trial period.

This is a significant trial period. 🎉

The industry standard is a 100-night trial period.

The trial period gives you the chance the test the mattress in the comfort of your own home to see if it's a perfect fit for you.

Generally, it will take your body a few weeks to get used to a new mattress. 🗓

This can be three weeks but can also take up to 6 weeks or longer, especially if your new mattress is vastly different to your old one.

Mattress trial period

How to return a Simba mattress

  • Can I buy Simba mattresses via Amazon UK or other stockists?

    The Simba mattress is available via Amazon in the UK and at a few select retailers, like John Lewis.

    You'll even get your trial and 10-year guarantee if you purchase via Amazon.

    But, we'd always recommend purchasing directly from the manufacturer.

    This guarantees that you have Simba-assured quality and get the best customer service. 


  • Can you offer Simba mattress comparisons?

    The Simba mattress may be a high-quality mattress that we'd highly recommend - but how does it compare to some of the other best mattresses in the UK?

    We've compared the Simba Hybrid to some of the UK's most popular mattresses.

    You can read our full comparisons below:

    The most important part to remember is that many other bed-in-a-box mattresses are all-foam mattresses.

    The Simba, in contrast, is a hybrid mattress, which gives it very unique properties.

  • What are common Simba mattress problems?

    While the Simba Hybrid is an excellent mattress, some customers have reported Simba mattress problems.

    Often, these are simply because the Simba is a wrong fit. 

    For example, people who find the mattress too soft or firm aren't struggling with a Simba mattress problem - they're merely struggling with a compatibility problem.

    Similarly, those who find the Simba mattress too hot may just need a pure pocket spring mattress instead of a hybrid.

    The Simba Hybrid mattress may be more or less suited to you, depending on your body size, weight, and preferred sleep position. 

    We'd recommend using Simba's trial to determine if the mattress is the right fit for you. 

    But what about other Simba mattress problems?

    Some customers may find that their Simba mattress begins dipping or sagging in the middle after only a few months of use.

    This is likely because:

    • The mattress is being used by an individual heavier than the maximum weight limit.
    • The mattress hasn't been rotated head to toe once a month for the first three months (and then every six months thereafter).
    • The mattress hasn't been placed on a suitably supportive bed base or frame with slats that are too far apart.

    If none of these applies, there may be a manufacturing fault, and you can rely on Simba's 10-year guarantee to keep you covered.
