It moves like you do.™ The 4moms mamaRoo4 infant seat bounces up and down and sways from side to side, just like parents do when comforting their baby. Select from five unique motions, like car ride and tree swing, and five different speeds. Choose from four built-in sounds or connect it to any MP3 player. The seat reclines to multiple positions to allow baby to lie back and relax or sit up and play. The mamaRoo is also Bluetooth enabled so you can control the motion, sound, speed and volume from your compatible smart device without disturbing baby! The overhead toy mobile now includes interactive, reversible toy balls. Keep baby 's attention with the sound of the crinkle ball, rattle or reflective mirror ball. While both feature 5 unique motions that bounce up and down and sway from side to side, just like parents do, the mamaRoo sleep bassinet and the mamaRoo infant seat have different uses to provide baby the comfort or entertainment they need. The mamaRoo infant seat is designed to comfort, soothe, and entertain baby. It can be used throughout the day or when parents need a hands-free moment. Pair the infant seat with the mamaRoo sleep bassinet by 4moms which features a firm, flat sleep surface that is designed to help baby fall asleep and stay asleep. It can be used for both overnight sleep and naps throughout the day. The five natural motions in these two soothing solutions make the perfect pair for new parents and baby. The mamaRoo is an infant seat used to comfort, soothe and entertain your baby. It is not a sleeper, nor intended for overnight sleep, since it is neither a flat surface (there is always a slight recline), nor a firm surface, as recommended by pediatricians. Never leave your child unattended. Looking to add an accessory?
