Study of main and cross-over effects on pressure relief among body mass index (BMI), body position and supporting material properties

Pressure ulcers form where bone causes the greatest force on the skin and tissue and squeezes them against an outside surface. This may be where bony parts of the body press against other body parts, a mattress, or a chair [1]. Wheelchair users or some patients with disabilities are at a high risk of developing pressure ulcers because of their limited mobility. Long-term lying or sitting with high interfacial pressure can result in pressure ulcers. Thus, different types of mattresses or cushions are designed to prevent pressure ulcers by increasing the contact area or reducing the interfacial pressure.
