A multiple roll tissue material dispenser assembly and method for forming a dispenser configured to dispense respective vertically stacked rolls of tissue material. The dispenser assembly includes a carriage that moveably cooperates with a support frame to allow dispensing access to a second vertically stacked roll of tissue material without outside interference. The carriage supports an actuator assembly that cooperates with a lower roll of tissue material and a channel defined by the support frame to allow selective access to an upper roll of tissue material. Depletion of the lower roll of tissue material effectuates rotation of the actuator to automatically effectuate the gravitationally downward slideable translation of the carriage relative to the support frame to allow access to an upper roll of tissue material supported by the carriage.
