Congratulations on choosing BabyBjorn Bouncer Balance Soft! It was developed in close collaboration with pediatricians and has a unique ergonomic shape that gives your child's head and back the correct support. BabyBjorn Bouncer Balance Soft may be used both as a bouncer and as a comfy chair. It can be used as a bouncer from newborns (at least 8 lbs/3.5 kg) until your child has learned to sit up without help. When your child can walk and sit on his or her own, you can turn the fabric around to create a comfy chair (up to 29 lbs/13 kg or approx. 2 years).
