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 new 4moms mamaRoo4 features a cool mesh fabric with a smooth, breathable surface to maximize airflow and keep baby cool and comfortable. The mamaRoo4 is designed with a back fabric consisting of a 3D air mesh that provides enhanced breathability and airflow, while the front fabric is a smooth, nest-knit material that provides cooling comfort. The updated design features fresh and modern colors. The overhead toy mobile reflects these updated colors with reversible, removable toy balls to keep baby entertained. Keep baby’s attention with the sound of the crinkle ball, rattle or reflective mirror ball. Compatible cool mesh newborn insert sold separately.
