Can temperature affect the firmness of the pillow?Updated 8 months ago

Yes, temperature can affect the firmness of the pillow!  Memory foam is temperature sensitive so the heat from your body softens the material and causes it to yield to weight.

The general environment can also play a part in this. For example, if exposed to unusually warm temperatures, the pillow will become more flexible. By the same token, if exposed to cooler temperatures, the foam can become a little more firm. The air flow holes in the foam do however help in reducing the difference you may noticed based on temperature!
