1. A method of controlling a microclimate of a mattress, comprising:
determining a time period of expected user sleep;
sensing whether a user is present on the mattress;
in response to sensing presence during the time period of expected user sleep, flowing air through the mattress at a first flow rate in a first operation mode to control microclimate of the mattress while the user is on the mattress;
in response to sensing that the user exited the mattress since a beginning of the time period of expected user sleep, flowing air through the mattress at a second flow rate in a second operation mode that is different than the first operation mode, the second flow rate being higher than the first flow rate; and
in response to sensing that the user returned to the mattress after the user exited the mattress and before an end of the time period of expected user sleep, resuming the first operation mode.
