The Bouncer Bliss bouncer chair requires no batteries to soothe babies with 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 charcoal-grey bouncer has an ergonomic design that supports baby's back, neck and head. The chair adjusts to three different positions to adjust as baby grows. The lightweight bouncer chair folds down for moving about the house or popping into a travel bag and includes a handy bag for transport.
