Comfort and firmness
We classify the Simba Hybrid as a medium-firm mattress and have placed it at 5.5 out of 10 on the Sleep Hero firmness scale.
The best of all materials
The special combination of springs and different foam layers allows the Simba Hybrid mattress to highlight the advantages of each of the materials used.
The top layer, which is very similar to ordinary latex, provides a pleasantly soft lying feeling.
The conical pocket springs adapt well to the body and allow for even pressure distribution. This eliminates pressure points and allows for a comfortable feeling when lying down.
It's also great to eliminate back pain and help with orthopaedic concerns.
The memory foam also adapts well to the contours of the body and provides softness to the mattress.
The cold foam base layer adds stability and support.
Best suited to light- and average-weight sleepers
Overall, the Simba Hybrid mattress seems to be particularly comfortable for light- and average-weight sleepers.
While heavier-weight sleepers could also find the mattress quite comfortable, they may sink in a little too deeply due to the softer foam layers and perceive the Simba Hybrid mattress as too soft.
That said, the mattress still provides sufficient stability.
If heavy-weight sleepers prefer a softer surface, then the Simba Hybrid may be well suited to them after all.
In this case, it would be best to test the mattress during a risk-free night trial period to see if it's comfortable.
Very comfortable when lying on your side
While technically suitable to all sleeping positions, we found the Simba Hybrid mattress particularly comfortable when lying on our side.
The mattress gives way in the shoulder and pelvic areas, allowing for optimal spinal alignment and a relaxed sleeping position.
We also slept very well on our backs.
The only position that wasn't entirely comfortable was when we slept on our stomachs. It didn't feel like the mattress offered enough firmness, resulting in a slightly hollow back.

Optimal sleeping climate
The interaction of different foams and springs, plus the breathable cover, allows the Simba Hybrid mattress to regulate temperature very well.
The space between the springs allows for natural ventilation channels, which increases airflow.
This is great as memory foam generally retains more heat than other foams.
The combination of the two then works well together.
The top layer of Simbatex latex foam also contains graphite, which has a cooling effect.
All of this results in a mattress with excellent breathability and a temperature-neutral sleeping climate.
Low motion transfer makes it great for couples
The materials used in the Simba mattress minimise motion transfer, which makes this mattress great for couples.
Motion transfer refers to the movement that is carried through the mattress.
If a mattress has low motion transfer, it means that you won't be disturbed by your partner's movements at night.
If you're sharing your bed with a partner, we'd still recommend that you choose a larger bed. Double, king-size or super king mattresses are great choices.
A mattress of this size guarantees that you'll have enough space to sleep comfortably.

To really test how well the mattress responds to different sleeping positions, we measured how deeply we sank into the mattress in a variety of positions.
The values are based on the body measurements (1.82 m and 72 kg) of our test sleeper.
||Depth of sinkage
|Lying on the back
|Lying on the side
|Sitting on the edge
|Standing in the middle
From this, we can determine that the Simba Hybrid responds optimally.
You will sink in optimally where necessary, such as in our shoulder area, which is beneficial in keeping your spine optimally aligned - particularly when sleeping on your side!
