Claim 17:
18. An air bed system comprising:
a mattress comprising a first and a second inflatable air chamber;
an air pump;
an air flow control system comprising:
a manifold coupled to the air pump, the manifold configured to control a flow of air from the air pump to the first and the second inflatable air chamber, the manifold comprising:
a manifold interior;
an inlet conduit extending from the manifold interior, the inlet conduit fluidly connected to the air pump;
an unvalved vent conduit fluidly extending from the manifold interior to an atmosphere and configured to conduct the flow of air to and from the manifold interior;
a first outlet and a second outlet extending from the manifold interior, the first and second outlets each fluidly coupled to the first and second inflatable air chambers, respectively; and
an exhaust port fluidly connected to the atmosphere;

a first valve and a second valve coupled to the manifold, the first and second valves operably connected to the manifold to selectively open and close the first and second outlets, respectively;
an exhaust valve operably connected to the manifold to selectively open and close the exhaust port; and

a controller comprising one or more processors and a memory, the controller operably coupled to the air pump and the air flow control system, the controller configured to perform operations comprising:
opening the first valve without opening the exhaust valve to allow for slower deflation of the first inflatable air chamber through the unvalved vent conduit; and
after opening the first valve without opening the exhaust valve, opening both the first valve and the exhaust valve to allow for faster deflation of the first inflatable air chamber through the exhaust port.
