A coccyx cushion is designed to relieve pressure off the tailbone by redistributing the user's weight. These seat cushions often are contoured or have a u-shaped cutout. The cutout should be positioned at the back of the seat so that the tailbone does not come into contact with the seating surface. These products reduce the pain and discomfort associated with sitting on a bruised or injured coccyx. Another benefit of a coccyx pillow is that it promotes good posture.
