Product Description Integrated NeverFlat pump technology: select desired comfort level, engage primary pump, and it shuts-off automatically at your chosen setting. Senors continuously monitor air pressure throughout the night, and a silent secondary pump engages automatically to maintain consistent firmness and comfort. NEVER FLAT TECHNOLOGY: Our twin air mattress has 2 inflation pumps. One handles rapid inflation and deflation at the turn of a dial.
