An air bed comprising an air mattress having a plurality of interconnected rows and columns of air cells divided into longitudinally isolated zones, and an airflow control system for supplying air at differing pressures to the zones such that a person reclining atop the mattress is supported and maintained in spinal alignment at subischemic applied pressures. The airflow control system includes an air pump, a plurality of air regulators, and a plurality of air supply lines connecting the pump to the individual zones through a corresponding regulator. If a particular zone is below or above a preset pressure the regulator therefor will either route air from the pump to the zone or will exhaust air from the zone.
