The Regalo Baby My Little Seat(TM) 2-in-1 Floor and Booster Seat enables your little one to sit up on their own and grow into a booster seat as they develop. Made of soft, yet durable expanded foam the seat is comfortable, easy to clean, and designed for durability and safety. The floor seat is ideal starting at 4 months when your baby is able to hold their head up. As they grow the seat transitions to a booster beginning at 6 months, through the transition to solid foods and beyond! It is great for development activities and mealtime as it comes equipped with an attachable tray.
