Pressure mapping makes use of a computerized pressure-sensitive mat to quantify pressure under a seating surface; it is commonly used by clinicians to determine the suitability of a wheelchair cushion and by researchers investigating support surfaces, risk factors for ulceration, and ulcer prevention protocols.
Pressure maps can come in all sizes, but those most commonly used are the thin mats preferred by seating specialists. These mats are composed of a matrix of small sensors and a cover. When a person sits on this mat, the sensors gauge the pressure being exerted at individual locations on the thigh or buttock. This data is transferred to a computer where a clinician analyzes it.

Patients with the following conditions may be candidates for pressure mapping:
