Bouncer Balance soft can be used for newborns and up to the age of 2. In the early months (up to 20 lbs/9 kg), you can use it as a baby bouncer. When your child weighs more than 20 lbs/9 kg and can sit up unaided, simply convert the baby bouncer into a comfy children's chair by turning the fabric seat around. You can use it as a chair until your child weighs 29 lbs/13 kg.
