The central bulge gently stimulates the pelvic floor muscles (PC muscles). Simply place it on your usual chair or the floor to incorporate self-care into your daily "sitting time." Recommended for those concerned about posture or who want to be mindful of their hip line. Can be used during desk work, housework, watching TV, and other "multi-tasking times." Lightweight and compact, making it easy to use at home or in the office! A self-care item that can be started without special knowledge or skills, even for those who are not good at exercise.
