Systems and methods for monitoring pressure at a contact surface, for applications such as pressure sore prevention. The system includes a number of force sensors positioned at different locations in relation to the contact surface, the force sensors providing a signal in proportion to the amount of force detected. The system includes a controller for receiving the signals from the force sensors and determining values associated with each force sensor. The controller is configured for comparing a first one or more values associated with a first subset of force sensors with a second one or more values associated with a second subset of force sensors, determining from the comparing whether a threshold between said first one or more values and said second one or more values has been exceeded, and controlling, based on the determining, an indicator to provide an indication to the user.
