Kerata Dial Fit Hip Seat [Age Range] 6 months (after the baby can sit up) to 36 months [Recommended] Up to 15kg [Size] Adjustable I used this for about 2 years after purchasing it. I am selling it because my child has outgrown it. There is some wear on the inside of the waist belt. There are no instructions or box. This is not new and has been stored at home, so please understand this before purchasing.
