Will the Joey Mattress Protector make my mattress hotter?

We specifically designed our mattresses so they would sleep cool, and we designed a protector that would do the same. Goodness knows we need it with this Malaysian weather.

To ensure a cool, pleasant sleep environment, we also chose a breathable protective film for ultra-breathability. It's the same material used in premium sportswear to keep athletes cool and dry, guaranteeing you the ultimate breezy bliss.
