A device 10 for controlling the inflation pressure of an inflatable pad or cushion includes a control unit 15 connected to an outlet tube 12 of a pump 11, and an inlet tube 17 of a cushion etc to be inflated. The control unit includes means for converting the pressure of air from the pump sensed by a pressure sensor in the unit 15 to an equivalent body weight deemed to be the optimum to be supported at that pressure. There are means 18 for displaying the equivalent body weight, and for inputting a target weight, and alerting the user when the target weight is matched or exceeded.
