A method of upgrading a bed assembly from (a) a first configuration in which the bed assembly includes a foam mattress, an articulating frame for supporting the foam mattress, and a drive system for moving at least one section of the articulated frame, to (b) a second configuration in which the bed assembly includes an air mattress, the articulating frame, and the drive system, is disclosed. The method includes the steps of removing the foam mattress from the articulating frame, placing an air mattress that includes at least one air bladder on the articulating frame, coupling an air control module pneumatically to the at least one air bladder, and coupling the air control module electrically to the drive system so that command signals received by the drive system to adjust pressure of the at least one air bladder are routed from the drive system to the air control module to operate the air control module to adjust pressure of the at least one air bladder.
