New Baby Bjorn Bouncer Bliss is a cozy place for your baby to play or rest beside you while you take a shower or prepare a meal. The baby bouncer rocks gently when babies kick their legs or wave their arms. No batteries needed – the baby bouncer runs on pure fun! Playing in the baby bouncer also helps your baby develop motor skills and balance. Bouncer Bliss can be used for newborns and up to the age of two.
