Wheelchair users are at great risk for pressure sores (decubitus ulcers). A number of factors are included in the formation of these ulcers including: # insufficient vascularization in areas of high pressure, typically under bony prominences' # the collection of sweat on the skin due to inadequate air flow, # the presence of local areas of elevated temperature # shear stresses on the skin A number of studies point to interface pressure between the body and the seating surface as the primary contributor to the formation of pressure sores.〔 In response, manufacturers have developed a number of wheelchair seat cushion alternatives to combat this breakdown.
