With the A1 air bed system, it is up to you how soft or hard you lie. You can regulate the firmness of your mattress from head to toe by radio remote control. The 7-zone air core of the A1air was designed exactly according to the human anatomy: While shoulders and hips sink in softly, the back and buttocks are supported precisely. The A1 -Air is made of Gelax foam, a further development of the visco-foam, which was originally developed for space travel. This high-tech foam adapts to the shape of your body. Pressure points are prevented, capillaries are better supplied with blood and tension is prevented.
