Dreamsweet Memory Foam Tailbone Seat Cushion Pad for Driving, Office, Home Sitting Comfort, Gray
The cushion features a user-removable cutout piece (hidden inside the cotton cover) for those who suffer tailbone pains. Leave it in for more comfort, if one doesn't have tailbone problems. Besides the comfort of the memory foam cushion, the wedge shape design keeps you sit in a slightly tilt-forward position, which helps maintain a correct sitting posture and reduce lower back pressure and pain.
