From the official website:

Just about 3 minutes each time. Lie down and gently sway to slim down your troublesome waist area.
Developed with reference to the techniques of osteopathic therapists.
14 protrusions target the muscles around your waist and hips.
The bottom of the unit is made of resin, making it easy to swing.
It can be used while sitting on the product, or placed on a chair or its backrest.
By swaying while supporting the natural curve of your lower back, it targets the surrounding muscles and pelvic area.
Gentle swaying also targets your hips.
Waist exercises can help you achieve a beautiful posture.
