Sacrum pillow (sacrum cushion) for spinal conditioning No logo included. I purchased this when I attended a spinal conditioning workshop, but I have kept it in storage at home as I have barely used it. I would like to pass it on to someone who will use it. As shown in the third photo, the curved part is slightly jagged, but I believe this is how it was originally made as I have barely used it. Yellow foam cushion to support the pelvis and posture - Color: Yellow - Shape: For pelvic and posture correction - Material: Foam material
