I've only used it about twice since purchasing it. There are no noticeable stains. This is a sitting support belt that can be attached to adult chairs. It allows you to seat your child alone when there are no baby chairs available, such as at relatives' homes or restaurants, or even on high chairs without belts. You can attach it to your waist, freeing up your hands and making mealtimes easier. It's lightweight, compact, and convenient to carry. It won't take up much space in your diaper bag.
