SIMBA MATTRESS REVIEW

The Simba mattress is a so-called hybrid mattress, and thus clearly stands out from its competitors. It is made of an innovative combination of pocket springs and foam layers.

The Simba mattress offers four different layers, considerably more than many other manufacturers. These layers are latex foam, conical pocket springs, Viscoelastic foam, and cold foam.

• Top layer: 4 cm latex foam. This layer is formed by what is called Simbatex foam, a synthetic latex layer. The Simbatex foam provides a soft feeling when lying down. This layer is also very breathable, which creates a cooling effect.
• Second layer: 2 cm pocket springs. Here, the manufacturer integrates pocket springs into the mattress core. Several thousand conical springs are used. These adapt to the body and thus provide an improved lying sensation. This layer also cushions body weight, which gives the Simba its characteristic springy feeling. In addition, the pocket springs also provide excellent pressure relief.
• Third layer: 3.5 cm Viscose foam. Visco (or memory) foams are characterised by their adaptability. This layer supports the body and also absorbs body heat. One disadvantage of Visco foam mattresses is that movements are strongly absorbed and turning over on the mattress may be difficult (referred to as post-swinging behaviour). Memory foams are also very temperature-sensitive. This isn’t the case with the Simba. The Simba mattress makes use of high-quality Visco foam and seems to compensate for the standard Visco problems with their first and second layers.
• Bottom layer: 15.5 cm cold foam. The fourth and lowest layer of the Simba mattress is a base layer of cold foam. It is divided into seven zones. This layer gives the mattress its necessary stability and allows the body to gently sink into the mattress as required.

Simba’s unique structure fascinates us. It combines the advantages of a spring mattress and a pure foam mattress and uses high-quality materials. The cuddly foam layers provide for a comfortable lying sensation, while the springs provide elasticity and bounce.

The springs also help with post-swinging behaviour and pressure relief. This allows the mattress to adapt well to the shape of the body, and it only gives way where the mattress is directly loaded.

The cover of the Simba mattress is exclusively available in a stylish shade of grey. It is made of 100% polyester. The top cover is pleasantly soft and made of breathable and air-circulating material.

We would classify the Simba as a medium-firm mattress. It is very suitable for any base, be it a slatted frame or a box spring. We’ve rated the Simba at a 5.5 out of 10 on the Sleep Hero firmness scale.

The Simba mattress clearly stands out and provides for an extraordinary sleeping experience. This is largely due to its special combination of spring and foam layers.

The top layer, which is very similar to latex, provides for a pleasantly soft feeling when lying down. In the second layer, the integrated conical springs guarantee that the mattress adapts well to the body of the sleeper, allowing pressure to be distributed evenly. This creates a pleasant lying sensation and avoids pressure points, which can cause pain and discomfort. Finally, the memory foam provides excellent stability, particularly for light- and medium-weight sleepers.

We particularly liked the Simba mattress while sleeping on the side. This position was very pleasantly relaxing as the mattress allows for the perfect amount of sinkage in the shoulder area. This keeps the spine in a natural alignment, allowing for a relaxed and healthy sleeping position.

Even heavier-weight sleepers will get good stability on the Simba mattress. This is because the foam layers provide extra stability and support, ranking the Simba higher in terms of stability than a pure spring mattress. That said, many people may prefer to sleep on a firmer mattress.

We also slept very well on our backs.

The only sleeping position we weren’t convinced by was sleeping on our stomach. We noticed what we may describe as a slight pulling in the back area after a little while, which felt like the formation of a hollow back. If you like to sleep on your stomach, then we would recommend looking at different mattresses. We’d suggest taking a look at our article on the best mattresses for stomach sleepers.

The Simba mattress is also breathable, combining the advantages of a spring mattress with those of a foam mattress, and we did not sweat heavily during the night. You may feel cocooned by the mattress due to its thin upper layer, but the sleeping climate is well regulated by the underlying spring layer. Heavy sweating can often be a problem with pure foam mattresses, especially those made exclusively of Viscose foam. Given the Simba’s unique composition and excellent temperature regulation, we can easily recommend it even for warmer summer nights.

By providing sinkage values, we can clearly show you how the mattress responded in different sleeping positions and how deeply we sank into the mattress. The values are based on the body measurements (1.82 m and 72 kg) of our test sleeper.

The Simba offers excellent sinkage. Your body will sink in well in the necessary areas, particularly in the shoulder area, which is beneficial in keeping a healthy spine alignment, particularly while sleeping on your side.

The sinkage depth while lying on the back may seem quite deep but this value is quite normal. Only heavier-weight people (90kg+) could sink in too deeply and find the mattress too soft.

It is important to choose the right slatted frame to go with your new mattress. This is particularly important with a mattress like Simba, which integrates springs. We would suggest that you choose a rigid frame and not an adjustable slatted frame.

The Simba mattress is shipped rolled-up in a compact box. Shipping is free of charge and the mattress will be delivered directly to your doorstep. Once delivered, you benefit from a 100-day trial period, where you can test the mattress in the comfort of your own home. If you’re not completely satisfied with your purchase, you can simply return it.

In order to return the mattress, all you need to do is contact Simba customer service. Collection and return will be organised by the manufacturer and is completely free of charge. You will receive a full refund within a few days.

The unique composition of the Simba mattress, combining foam layers with a spring core, ensures that the mattress adapts very well to the body. The slightly springy lying sensation definitely sets the Simba apart from its competitors.

At a price of £799 for a 140 x 200 cm mattress, the Simba falls into the upper-middle price range. But the mattress is well worth it, and you’ll receive a high-quality product that will last for many years. And due to the 100-day trial period, your purchase is also completely risk-free.
