Simba Mattress Review

simba hybrid mattress review

Simba was one of the first UK mattress in a box brands, founded in 2015.

When designing the mattress, Simba has worked closely with “The Sleep To Live Institute”, involving more than 10 million people and measuring 180 million body profile data points, with the mission to create one of the most comfortable mattresses on the market.

The result is the Simba Hybrid mattress, which perfectly combines cutting edge design, foam and springs. In addition, all foams in the mattress have received the CertiPUR label, ensuring that there are no unwanted chemicals found inside.

They recently introduced the Simba Hybrid Pro mattress which has up to 5,000 Aerocoil springs and a layer of wool. As well as the Simba Hybrid Luxe and Ultra. 

What’s inside the Simba Hybrid mattress?

The Simba Hybrid Mattress is the company’s original mattress, with over 1/2 million sold. It is 25cm deep and is comprised of 5 layers.


Layer 1: Sleep Surface – breathable hypoallergenic sleep surface.
Layer 2: Simbatex – their own patented cooling layer, which is incredibly breathable and helps to promote airflow to cool the mattress naturally.
Layer 3: Springs – 2,500* conical pocket springs (for the King size mattress), which adjust to a person’s shape and movements, minimizing motion transfer between sleeping partners.
Layer 4: Visco memory foam – moulds flawlessly to a person’s body shape.
Layer 5: Support base – promotes durability, comfort and additional temperature control.

Here the mattress cover can’t be removed or washed, that’s why it’s recommended to use the Simba Hybrid with a mattress protector.

What’s inside the Simba Hybrid Pro mattress?

The Simba Hybrid Pro Mattress is the company’s bestselling mattress. It is 28cm deep and is comprised of 8 layers, including British wool.

It is one of Simba’s most advanced mattresses ever, since it has a dual spring layer with up to 5,000 titanium Aerocoil springs. This means that there is greater airflow and better weight distribution. 

There is also a natural wool layer and an open-cell foam layer which you won’t find in Simba’s original Hybrid mattress. Wool is known to naturally regulate temperature, so you won’t feel hot or cold all year round.

Finally, you’ll notice that here you have an even thicker knitted cover, which provides a super soft sleep surface. 

There are two more models, which are more luxurious and have more layers inside: Simba Hybrid Luxe has 11 layers, 31 depth and up to 6,000 springs, while the Simba Hybrid Ultra has 13 layers, 34cm depth and up to 8500 springs inside.

All Simba mattresses are made in the UK and come with 10 year guarantee. Plus all foams used have received the CertiPur label, which means that there are no unwanted chemicals found inside. All mattress have a medium firm feel. 

In addition to the memory foam, there are 2,500 micro springs inside the King size Simba Hybrid mattress, with a height of 2cm. Inside the Simba Hybrid Pro you have two layers of springs which are up to 5,000. 

The Simba mattresses can be used by people no matter their sleeping position (back, side, or stomach).
