It is true that it can only take a few hours, or even less.  And the reason for that is because the pressure, unrelieved, impedes blood flow to that area.  And when the skin or the underlying tissues are deprived of blood supply, they are also deprived of oxygen and nutrients, and there’s cellular death.  Some people tolerate this loss of blood supply better than others.  That’s why some spinal cord injury patients can sit longer and lay in different positions longer than others.  We don’t know how long it takes for each individual patient to suffer from this blood loss, or what we call ischemia.
