An air bed structure capable of alternate lying thereon on either of one's sides, wherein, the air bed is divided into an upper and a lower layer, each layer is divided into a right and a left part each being comprised of an air bladder. A U typed air bladder is provided between the upper and the lower layers. The air bladders are arranged to cooperate with two specific air valves, multiple pipe lines and a controlling electronic circuit to provide various aeration states including single air-bladder aeration on both sides of the air bed, single air-bladder aeration on one side of the air bed, both air-bladder aeration on one side of the air bed, single air-bladder aeration on the other side of the air bed and both air-bladder aeration on the other side of the air bed etc. Thereby a patient lying on the air bed can adjust the aeration state of the air bed in pursuance of requirement. The body of the patient can be raised to rotate rightward, leftward by making a small or big turning of his body. This is extremely ideal and convenient for patients and old people.
