Any chair can be comfortable for long periods of sitting when you use this coccyx gel seat cushion. This seat cushion for tailbone pain provides comfort through a soft chair pad with a supportive gel center. A special cutout at the back of the gel pad is also included to relieve pressure at the tailbone. Our coccyx cushions come complete with a removable cover for easy cleaning. Faux Sherpa lines the top of each navy blue polyester cover. Hand-wash the covers in cold water and line-dry them only.
