Since the Simba pillow features memory foam, it's easy to assume that it may sleep hot - as memory foam products often do.
But, the Simba Hybrid is a cooling pillow, which is largely due to the unique Simba pillow cover.
Let's look at this in a tad more detail. 👇
Simba Hybrid pillow cover
The Simba pillow case feels soft and cool to the touch.
It is divided into two separate sleeping surfaces:
Top half with Stratos technology
Bottom half made of breathable cotton
The Simba pillow case has been uniquely designed to keep you cool. ❄️
Simba Stratos technology
The top half of the pillow cover, marked by the blue border, contains Simba’s revolutionary Stratos technology with active temperature regulation.
Stratos is a temperature-regulating fabric that absorbs, stores, and releases heat as required.
The fabric will release heat if your body temperature drops but store heat if your body temperature is high. 🔥
This keeps the cover perfectly temperature-regulated, providing for a comfortable sleep no matter the season.
Naturally breathable cotton
The other side of the Simba pillow case, marked by the grey border, is made of naturally breathable cotton.
Simba only uses BCI-sourced cotton. 🌱
The Better Cotton Initiative is a programme that encourages higher standards of sustainability within the cotton industry, supporting cotton producers and reducing the impact the industry has on the environment.
Separating mesh border
The two halves of the pillow are divided by a distinct mesh panel.
This not only enhances the design of the pillow but also serves an active cooling function. 💨
The mesh border allows for greater air circulation within the pillow, keeping the nanocubes cooler and removing excess heat.
The design part is subjective, though. The border of the pillow will shine through a white pillowcase - it did for us, at least. This was definitely a downside when we did our Simba Hybrid pillow review. If you're looking for a clean white bedroom look, then this pillow might not be the right fit for you.
Can you wash Simba pillows?
The Simba Hybrid pillow cover can be machine-washed at 40℃ and tumble-dried on low heat. 🧼
The nanocubes cannot be washed.
To wash your pillow cover, simply remove the inner pouch containing the nanocubes and pop the cover into the machine.
To protect your pillow, you should also use a pillowcase.
This won’t interfere with the Stratos technology.
If you’re a heavy sweater or enjoy your morning coffee in bed, we’d also recommend you opt for a pillow protector. ☕️
You won't find any branded Simba pillow protectors, but we can recommend a few alternatives.
