mamaRoo4 infant seat
It moves like you do™
The only infant seat that replicates natural motions of parents.
Believe in better®
Parents don't vibrate like bouncy seats or swing like baby swings. We believe that infant seats would be better if they replicated the natural motions parents use to comfort their babies. That's why we created the 4moms® mamaRoo®4 infant seat. We put sensor vests on parents to understand those motions and then replicated the bouncing and swaying in the mamaRoo to soothe and entertain better than traditional infant seats.

Setup & Instruction manual

How do I clean the mamaRoo seat fabric?
The seat fabrics (plush, classic and cool mesh) and the newborn insert are machine washable. We recommend washing them in cold water on the gentle cycle. Do not use bleach. Tumble dry separately on low heat and remove promptly from dryer.
What's the difference between the plush, classic and cool mesh fabrics?
The mamaRoo4 infant seat is available in a plush, classic, and cool mesh seat fabric. The plush seat fabric is a softer, blanket-like material, available in two patterns: multi plush and silver plush. The classic seat fabric is a smooth, woven polyester material and is available in both grey and black. The cool mesh seat fabric is a breathable, mesh material and is available in dark grey. All are easily removable, machine washable, durable and comfortable.
What is the difference between the mamaRoo sleep™ bassinet and the mamaRoo® infant seat?
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 sleep bassinet features a firm, flat sleep surface that is designed to help your baby fall asleep and stay asleep longer. It can be used for both overnight sleep and naps throughout the day.
The mamaRoo infant seat is designed to comfort, soothe, and entertain your baby. It can be used throughout the day or when parents need a hands-free moment. The mamaRoo infant seat is not intended for extended or overnight sleep since it is neither a flat surface (there is always a slight recline) or a firm surface as recommended by pediatricians. If your baby falls asleep in the mamaRoo infant seat and you’re not able to provide the required supervision, we recommend moving the baby to a separate approved sleep surface.
