The First Years Soft Trainer Seat Designed to encourage independence and confidence in potty training, this seat features a soft, comfortable air-filled cushion that has a seamless, built-in backrest and low deflector. Two side handles make it easy for your child to put the seat onto the family toilet-and take it off-all by himself. The cushion snaps out of the frame for easy, thorough cleaning. Fits most standard toilets.
