The BABYBJÖRN™ Bouncer Bliss requires no batteries to soothe babies with its gentle rocking. In fact, once babies learn to control their kicks and arm movements, they'll have even more fun bouncing around. Made with stretchy and velvety-soft cotton-blend jersey, the bouncer has an ergonomic design that supports baby's back, neck and head and can be adjusted to 3 different positions as they grow. Once children can sit and walk unaided, the chair can be converted to a toddler seat by simply flipping the fabric over. Lightweight and foldable, the bouncer chair is easy to take on the go—whether you're traveling or just moving it around the house.
