How Does a Bed Cooling System Work?

Bed cooling systems use active cooling technologies, such as water or air circulation, to regulate the temperature. 

These systems often include a control unit that can adjust the cooling level according to your preference, ensuring optimal comfort.

How Does a Cooling Gel Mattress Work?

Cooling gel mattresses incorporate gel beads or layers within the foam. The gel absorbs excess body heat and redistributes it, preventing overheating and ensuring a cool sleep surface.
