Suitable from birth to 9kg. Soothes baby with 2 gliding motions - side to side and head to toe. The deep cradle seat offers extra support for baby's back, sides and head (add the infant insert to give baby even more plush support). There's a recline position for younger babies and a slightly inclined position for older babies. As baby glides back and forth with the chair's comforting motion, you can choose from soothing or playful music and baby can gaze at the plush toys overhead. Seat rotates 360 degrees. Carry handles for portability from room to room. Soft pad is machine washable. Requires 4 x D batteries (not included).
