A flexible layered material comprises an outer
skin; a first flexible fabric layer having a thickness of about 6mm to about 10mm; and a second flexible fabric layer having a thickness of about 17mm to about 22mm; wherein, in use, the outer
skin is capable of facing a patient; the first fabric layer is positioned between the outer
skin and the second fabric layer and comprises a plurality of first densely packed substantially parallel fibrous ribs between a first sheet
proximate to the outer skin and a second sheet distant to the outer skin; and the second fabric layer comprises a plurality of second densely packed substantially parallel fibrous ribs between a third sheet
proximate to the first fabric layer and a fourth sheet distant to the first fabric layer. The material is for use in an acute or hospital
care setting to reduce the occurrence of pressure ulcers caused either by skin shearing or the breaking down of tissue through a lack of
peripheral blood flow in patients required to spend time in a reclined or sitting position.
