Simba mattress composition
The Simba is a cutting-edge hybrid pocket-sprung foam mattress that combines high-quality pocket springs with multiple layers of foam:
- Soft, breathable top cover
- Open-cell, graphite-infused Simbatex foam
- 2000 Aerocoil conical pocket springs across 13 zones
- Open-cell, CertiPUR stability layer
- No roll-off SupportCore base with up to 1000 barrel springs
- Thin CertiPUR foam base
Let's look at all of these layers in a tad more detail.👇
Simba Hybrid mattress layers and cover
Let's briefly look at the mattress cover and the foam and spring layers of the Simba original mattress.
1. Simba mattress cover
The hypoallergenic Simba mattress cover is made of 100% polyester and includes grey mesh sides and a white hand-knitted top cover.
It has been designed for enhanced breathability and greater airflow and feels soft and cuddly to the touch.
Conveniently, larger mattress sizes feature four side carrying handles, which make moving and transporting the mattress easier (only the single-size and small double mattresses don't have handles).
The top cover is also removable and machine-washable at up to 40℃, but tumble-drying is not recommended.
To clean the grey base fabric of the cover, simply wipe it down with a soft, damp cloth.
Even though the mattress cover is washable, we still highly recommend using a waterproof mattress protector to further safeguard your sleep surface.
2. Top comfort layer of graphite-infused Simbatex open-cell foam
The top comfort layer of the mattress is made from a soft, open-cell polyfoam called Simbatex.
Its open-cell structure allows for greater breathability than closed-cell memory foam, ensuring enhanced airflow and heightened cooling properites.
The foam is also graphite-infused, further enhancing its cooling properties.
3. A layer of Aerocoil pocket springs
Up to 2000 mini pocket springs (25 mm 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, something that's further enhanced by their conical shape, allowing for better compression.
Individual coils are enclosed in polyester fabric pockets, which increases motion isolation and protects the surrounding foams.
4. A stability layer
A CertiPUR-certified [1] foam layer acts as a transitional and stability layer between the Aerocoil spring layer and the SupportCore base layer.
Previous versions of the Simba mattress featured high-density Simba-Pure foam with Edge Lift Technology and a memory foam and latex mix in this layer, which is why Simba was previously known as a pocket spring memory foam mattress.
Simba had redesigned its mattress to enhance cooling and breathability.
5. SupportCore base layer
The Simba Hybrid's base layer is made of up to 1000 durable barrel springs, which provide firm edge support for full mattress enjoyment.
The additional springs also allow for even better airflow, again enhancing the overall breathability of the mattress.
Exchanging the foam base for the spring base also affects the overall sustainability score of the mattress, as spring production has less of an environmental impact than foam production.
6. CertiPUR foam base
Despite the spring base, Simba Sleep still includes a thin CertiPUR foam layer, which works with the SupportCore base to enhance overall stability and support.
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.
That said, some of our test sleepers perceived the mattress as slightly firmer while others felt it was a little softer, but your exact experience of the mattress will depend on your body size and weight.
We'll go into some of this in more detail further down.
Our Simba mattress firmness assessment
To conduct an in-depth Simba Hybrid original mattress review and assess firmness more accurately, we measured how deeply our test sleepers 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 really gives.
When running our experiments, we ensure that we always take readings in the same place:
- If lying on the stomach, we measure at the stomach.
- If lying on the back and sides, we measure at the shoulders and hips.
This ensures fair and accurate measurements.
All of our test sleepers experienced a good amount of sinkage, suggesting that the mattress is definitely soft enough to accommodate lighter-weight sleepers and adjust to different sleep positions while still remaining very supportive.
This is important as you need to experience some sinkage when lying on a mattress to ensure optimal spinal alignment, but you don't want to sink in too deeply.
What does sleeping on the Simba Hybrid mattress feel like?
The combination of mini pocket springs and different foam and sprung layers allows the Simba Hybrid mattress to highlight the advantages of each of the materials used. ⭐️
- The top comfort layer provides sleepers with a pleasantly soft lying feel.
- 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 incredibly comfortable yet very supportive mattress that can help relieve orthopaedic concerns.
Is the Simba mattress suitable 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 our test sleepers - regardless of height, weight, body type, or sleeping position - reported that they found the mattress comfortable and that it supported their bodies well throughout the night.
The mattress was most comfortable when sleeping on the side and sleeping on the back.
In both of these positions, the Simba Hybrid manages to offer the perfect mix of support and sinkage, where heavier body parts sink in a little more and lighter body parts are supported a little more, resulting in optimal spinal alignment.
Is the Simba Hybrid supportive enough for larger builds?
While our test sleepers all found that this medium-firm mattress offers sensational support, we do not think it's firm enough for heavier or larger people - or even those who simply prefer a firmer feel.
This is because people of a heavier weight - and pure stomach sleepers, for that matter - often require a firmer mattress to provide enhanced stability and support. 🧱
We'd recommend heavier sleepers opt for traditional pocket-sprung mattresses or consider firmer all-foam or hybrid mattresses, like the Emma Original, Simba Hybrid Luxe, or the Origin Hybrid mattress.
Does the Simba mattress have good 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, and everyone remained well-supported throughout.
This means you can sit or lie at the end of the mattress quite comfortably without feeling like you're falling off the sides.
Edge support can be a deal breaker for couples wanting to use the entire width of the mattress or those who like to sit at the edge of their bed before getting up or going to bed.
Is the Simba mattress good for restless sleepers?
Many bed-in-a-box mattresses feature memory foam, which offers great orthopaedic support but tends to give you that "sink-into-your-bed" feeling.
This isn't ideal for restless sleepers.
The Simba mattress is a good alternative since it still provides body-contouring support, but you'll never feel stuck in it. 🥳
This means you can toss and turn as you wish, making the mattress particularly suitable for restless sleepers.

Does the Simba Hybrid sleep hot?
The Simba mattress features numerous cooling properties for superior temperature control:
- A knitted cover that enhances breathability.
- Open-celled Simbatex foam with cooling graphite.
- Pocket springs with natural ventilation channels that increase airflow.
These features improve breathability, enabling air to flow freely through the mattress and keeping you cool and comfortable all night long.
Our scientific temperature tests
In order to better demonstrate temperature regulation properties, we took some temperature measurements for our Simba Hybrid review.
The image demonstrates heat being stored exactly where the test sleeper lies while the rest of the mattress remains 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.
As a hybrid mattress featuring multiple springs, the Simba mattress does have some motion transfer, giving it that good bounce.
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 mattress sizes, like the Simba king-size mattress 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.

We answer some of the most common delivery FAQs below:
Can Simba remove my old mattress?
Simba offers an old mattress removal service at an additional fee.
How do I unpack my Simba mattress?
Your new mattress is super easy to unpack:
- Open the box and take out your mattress.
- Unroll the flattened mattress on your bed base.
- Cut the plastic and break the vacuum seal.
- Remove any other packaging.
Your mattress will begin inflating as soon as you break the vacuum seal, and takes roughly 3 - 6 hours.
Occasionally, though, it can take up to 72 hours for the mattress to expand completely.
Does the Simba mattress smell?
Our mattress didn't smell when we unpacked it, but you may notice a slight smell upon unpacking.
This is called off-gassing, something that's completely normal with compressed products and is not toxic or harmful in any way.
That said, we still recommend unpacking your new 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
All Simba mattresses come with a risk-free 200-day trial period, one up from the industry standard 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 take three weeks but can also take up to six weeks or longer, especially if your new mattress is vastly different from your old one.

To return the mattress, all you need to do is contact Simba customer service.
Collection and returns are organised by Simba and are completely free of charge within the UK.
Conveniently, you also don't have to keep any of the original packaging to return the mattress.

Don't fret: Returned mattresses are recycled or donated to charities. ♻️
Should you buy the Simba Hybrid mattress?
As our Simba review has hopefully shown, the Simba Hybrid mattress is a high-quality, supportive, and comfortable mattress that offers the perfect night's sleep.
We'd recommend the Simba mattress to:
- Light- and average-weight sleepers
- People who sleep on their side or back
- People who like a medium-firm mattress with a slightly softer feel
- Heavier sweaters or people who often feel hot at night
- Restless sleepers
- Couples
Heavier-weight people, those of larger builds, stomach sleepers, and those who prefer slightly firmer mattresses are advised to take advantage of the risk-free trial period to see if the mattress can support them well enough.

-
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.
Simba mattress dipping is likely when:
- 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.
