Bring the Bedroom Fan under the covers with the Mattress Cooler Air! The Mattress Cooler Air provides a breeze to cool down at night. This simple and reliable system allows hot sleepers to cool down with a mess-free, low-maintenance system. This low-power option is perfect for those with hot homes or rooms, bedrooms without ceiling fans, or apartments that don't allow water-based cooling systems. With its versatility, the Mattress Cooler Air is suitable for all beds. For beds with a +6-inch clearance, place the fan underneath your bed, thread the tube through the clamp, and place the clamp between the Mattress and Box spring near where you want to put the tube in your bed. You can place the tube where you want the most airflow, adapting to your unique comfort needs. Take control of your sleep environment with the Mattress Cooler Air. Place the tube at the bottom and point towards the head board to get air flow from toe to head, and vice versa to get air flow from head to toe. This customizable airflow ensures you can sleep in the most comfortable position for you. Place the tube on the side of the bed and point it across to get airflow moving across you. Place the tube near your head to get optimal airflow near your face. Features: The Mattress Cooler Air provides a breeze to cool down at night.
