Donut pillow

Donut pillows. As the name implies, this is a donut-shaped pillow that is placed on the seat portion of a chair. With either a depression or a hole in the center of the pillow, one can sit with much less pressure in the coccyx region (the tailbone). People who have suffered a broken or bruised tailbone or have coccygeal pain (such as coccydynia) may need this type of pillow in order to sit without pain.
