Say "sayonara" to secretary spread, the Beauty Bottom Cushion promises to maintain and encourage a shapely bum while you work.

Sound too good to be true?

This chair cushion works by guaranteeing correct posture, properly aligning your pelvis and spine, which in turn ensures that your bottom muscles become and stay taut enough to bounce a 100 yen coin off of. 

The plush foam is designed for maximum comfort while the soft pink and grey colors project a soothing style.
