A car cooling seat pad helps circulate air to reduce the heat and moisture in the car seat. Using a gel or air foam material, these cooling seat cushions work to reduce perspiration and absorb body heat. They are designed to fit most vehicles and can be plugged into the cigarette lighter.

The cooling seat pad consists of two main parts: a cushion and a base plate made of an iron sheet system. The base plate has an exhaust fan at the rear end. There is also an air channel between the cushion and base plate. The base plate also has a slit for an outlet for the air. In addition, the skeleton also houses a power lead which connects to the automobile's power supply.

A car cooling seat pad is available in a variety of sizes and types. Some can be as large as 18 square inches and can bear up to 200 pounds. Most of these seat pads are inserted into the seat of a vehicle and sit on the seat. These cooling pads are best used in cars that are parked in the shade.
