Title: A real pain in the bum...
Review: If use on a chair, the chair back pushes the "doughnut" hole on this cushion sits under your legs, not your tailbone. The cushion has a very hard ridge around the entire bottom so it will not conform to the contour of your chair. It actually made my sciatica and vertebral compression worse. Maybe if used as a flat backless bench cushion it would be okay. I had to return it!
