How it works: Speedvalve™ Amplified Airflow
Using physics to enhance 40+ years of Therm-a-Rest® mattress innovation.
Bernoulli's Principle of fluid dynamics helps explain why a SpeedValve™ mattress inflates so quickly. The specially designed valve uses physics to fill the NeoAir® mattress with more air than your breath alone.
When you blow into the valve from several inches away, your breath sends fast-moving, low-pressure air through the neck of the mattress, causing the static, high-pressure air outside the mattress to rush in to equalize the pressure.
Put simply, every breath pulls in surrounding air molecules to amplify the airflow and inflate the mattress faster and with less effort than with traditional valves.
