Lady Care uses two new concepts.
Facilitation - The roughened flat bottom makes it easier to 'catch' the vaginal cones if it is sliding out. Also, the lady care vaginal weights have non-slippery 'shoulders' which facilitate a muscle contraction when touching the pelvic floor muscles.
Self-positioning - The weight is placed at the bottom of the cylinders, whereby gravity prevents it from falling over and dislocating. The cylinder will position itself in the lower portion of the vagina, where it has the best effect.
