Portable Potty Seat I used to carry a portable potty seat because I wanted to toilet train my child even when we were away from home, but now that we've finished toilet training, I'm selling it. It has non-slip rubber on the bottom, so it never slipped after sitting on it. It's foldable and has gaps, but it comes with a rubber band, so there was no worry of pinching my child's thighs. I have washed and disinfected it before listing it for sale.
