Introduced here are pressure-mitigation systems able to mitigate the pressure applied to a human body by the surface of an object (also referred to as a “structure”). A controller device (or simply “controller”) can be fluidically coupled to a pressure-mitigation device that includes a series of selectively inflatable chambers. When a pressure-mitigation device is placed between a human body and a surface, the controller can continuously, intelligently, and autonomously circulate fluid through the chambers of the pressure-mitigation device. Normally, the controller circulates air through the chambers of the pressure-mitigation device, though the controller could circulate another fluid, such as water or gel, through the chambers of the pressure-mitigation device. The controller may cause the chambers to be selectively inflated, deflated, or any combination thereof.
