The McCarty's Sacro Ease Coccyx Cutout Comfort Memory Foam Car Seat Cushion Support is the ultimate seat for those with tailbone issues, tailbone pain, or otherwise need coccyx pain relief when driving a car or sitting in chairs.  

The Difference:  The fundamental difference between the McCarty's Sacro Ease BRSCMCF Coccyx Cutout Comfort Memory Foam Car Seat Cushion Support, and the other Sacro Ease Car Seat Cushion Supports is the fact that this support has 1 inch of comfort memory foam in both the seat and the back, as well as the coccyx cutout to help with the tailbone, coccyx or even hemmoroid pain and relief while sitting.  McCarty's tells us that most people find this coccyx cutout car seat cushion support to be more comfortable, even if you don't have coccyx or tailbone pain.
