The Red Castle Baby Sit Up Booster Seat allows your child to sit at the right height at the table at any time. This booster seat is much safer than pillows or books stacked on a chair. It elevates your child to the height of a desk, it is sturdy and is secured to the chair using straps that connect below the chair seat. Baby Sit Up can be used with the shallow side up, meaning your child is sat 12cm higher, while the deep side boosts the seat height by 9cm. This booster seat can double as a small chair when used on the ground. This booster seat is suitable for children of two years and older.
