1. An active comfort controlled bedding system comprising:
a bucket assembly comprising a side rail assembly extending about a perimeter to define a cavity;
a plurality of air bladders disposed within the cavity;
at least one pump disposed within the cavity configured to inflate or deflate one or more of the plurality of air bladders; and
at least one air blower assembly comprising a unidirectional air blower configured to flow air to and from a mattress surface overlaying the bucket assembly and plurality of air bladders, wherein the at least one air blower assembly comprises a circuitous and continuous conduit fluidly coupled to the unidirectional air blower; a bidirectional air flow conduit fluidly coupled to the circuitous and continuous conduit and including an open end in fluid communication with a location within the mattress, the bidirectional air flow conduit including at least one sensor for measuring a property associated with air flowing through the bidirectional air flow conduit from or through the open end; an inlet port fluidly coupled to the circuitous and continuous conduit at a location between an outlet of the unidirectional air blower and the bidirectional air flow conduit; an exhaust port fluidly coupled to the circuitous and continuous conduit at a location between an inlet of the unidirectional air blower and the bidirectional air flow conduit; adjustable valves in the inlet port and in the conduit between the inlet port and the bidirectional air flow conduit; and adjustable valves in the outlet port and in the conduit between the outlet port and the bidirectional air flow conduit, wherein the adjustable valves in the inlet port, the outlet port and the bidirectional air flow conduit are configured to provide bidirectional air flow through the bidirectional air flow conduit from the unidirectional air blower.
