Lying down in prone position for as long as is possible, especially at night, as it is the safest. (Persons with cervical level injury must check with their doctors whether this position is ok, as a few of them could have respiratory / breathing issues.). Lying down in prone position is the safest for a spinal cord injured person as the five most vulnerable spots are completely safe in this position. Make sure you do a push every 2 / 3 hours.
