Simba vs Casper Construction

Simba vs Casper Cover Review


The Simba mattress cover is made from 100% polyester, the top has a unique diamond stitching which is not only aesthetically pleasing but also allows for more airflow to pass. The bottom half is more durable as this is in contact with surfaces. The cover is machine washable which is a great plus and makes the cover very practical. Unfortunately, the cover does not include any handles for manoeuvering.


The removable Casper cover is made of 99% polyester and 1% elastane. The cover is relatively similar to the Simba cover, however, what stands out is that the cover includes 4 handles and is washable, but it must be mentioned that it isn't machine washable but have to clean it with the good old damp cloth and mild detergent.

Verdict - This is a close call when comparing the two covers, you will half to ask yourself what is more convenient for yourself, moving the mattress around or opting for a quick clean in the washing machine. Both covers are soft in nature and breathable. We enjoy the look of the Simba mattress more but this is subjective and bear in mind you most probably will be covering the mattress in your bed sheets.

Materials and Layer Comparison


The Simba mattress has a total of 4 layers. From all of our mattress reviews, this is the only mattress that has a synthetic latex layer, this shouldn't be confused with natural latex.

  • Synthetic latex layer - This layer incorporates natural cooling soybean balms which help to regulate sleeping climate so you never overheat during the night.
  • Conical pocket springs - These are mini springs which just add a slight bounce and help with balancing pressure disparities.
  • Memory foam layer - The slow responsiveness properties memory foam has to offer makes it a perfect transition layer in order to feel the benefits from all the layers.
  • Polyfoam base foam - This is where the Simba mattress gets its support. This layer is also castellated which means there are channels cut out in the shoulder and hip areas to always allow correct spinal alignment.


The Casper Mattress is made from 4 different foam layers. Generally, memory and foam mattresses have a total of 3 layers but by offering 4 there seems to be a better transition through the layers.

  • Open-cell poly foam - This layer has more air bubbles when compared to traditional polyurethane foam, this allows for more airflow and breathability.
  • Memory foam layer - The visco-elastic foam layer helps extend the body contouring throughout the mattress.
  • Polyfoam layer - This thin layer is just an additional layer to transition the comfort from the slow response memory foam layer to the more sturdy base layer.
  • High-density polyfoam - Finally, the castellated base layer adds support for the mattress.

Verdict - Although it is always difficult comparing a hybrid mattress with a foam only mattress, however, we do feel the Simba mattress does bring a bit more to the table. Simba is the whole package, synthetic latex, mini springs, memory foam, and polyfoam, we feel that most people will benefit from the combination of these layers when compared to the Casper mattress.

Comparing Firmness & Feel

We rated the Simba a 6.5/10 on the firmness scale, it's classified as a medium feel mattress. This way Simba can appeal to most of the sleepers out here in the UK.


Because the Casper has more layers than other foam mattresses and has more polyurethane foam layers when compared to the Simba, it feels slightly firmer. We gave it a 6.5/10 in terms of firmness.

Verdict - Research has shown that spinal alignment is best maintained on a medium firm mattress. Both Simba and Casper offer enough support but because the Casper is slightly firmer it may be the better option for those looking for a mattress that can hold more weight.
