The overlay, with its optimal shape and size, perfectly fits both oval and square toilet seats, guaranteeing universal use. To increase the grip of the toilet seat over the entire surface, we have used special anti-slip rubber bands that keep the overlay securely in place. In addition, our overlay is equipped with a soft seat, which not only provides additional comfort, but can also be easily removed and installed. This makes cleanliness easier to maintain, and allows the toddler to enjoy a comfortable experience using the toilet. In consideration of the anatomy of both sexes, we have used a spout that is high enough, eliminating the risk of waste leaking outside.
