A cooling pad includes a bottom section, a top section, and a middle section which together form a contoured surface to support a person's back. The contoured surface includes concave and convex sections, providing ventilated pockets which allow air to flow to a person's back. Inside the middle section there are intake holes, located on either side of the cooling pad, and exhaust holes, positioned atop and below the middle section. The intake holes allow air to be brought in from outside, while the exhaust holes direct air to cool a person's back. Fan and power systems are stored inside the middle section. The fan blows air through the exhaust holes. The system as a whole is designed to utilize negative pressure to bring fresh air in from the intakes, replacing the air the fan pushes through the exhaust holes. The resulting airflow prevents back sweat from occurring.
