Must Contain A . The reason a cushion is so important is that it can help prevent pressures sores.
Pressure sores are damage to tissue due to immobility.
They usually start out as simply a reddened area over the butt that doesn't go away. Untreated they can quickly evolve into an open sore that penetrates the skin, the muscle, and in some instances they can reach the bone. Open pressure sores may require a user to go on bedrest for weeks or months, to require intravenous antibiotics, or to require plastic surgery. Once someone has had a significant sore, they are more vulnerable to getting another sore due to the scarring that occurred from the first sore. Medical conditions that cause immobility, weakness, poor nutrition, spasticity, or altered mental status such as spinal cord injury, stroke, and cancer, increase the risk for skin breakdown.
