Gently lower the swing seat to create a safe and comfortable spot to rest without being disturbed. The swing seat reclines to a rocker with an easy, one-hand motion, giving your baby a safe and comfortable spot to rest without having to be moved from the swing. DuoGlider uses the same gentle motion as your nursery glider to soothe baby, and also features two-speed vibration, six swinging speeds, classical melodies and nature sounds and more to keep baby soothed and comfortable. You can plug it in or use batteries for two convenient options.
