The 4moms MamaRoo is the only baby swing built around a specific insight about how parents actually soothe their babies: the motion that works is not a simple back-and-forth pendulum but a combination of up-and-down and side-to-side movement that replicates what a parent's arms naturally do. The patented MultiMotion Technology delivers five distinct motion types based on that principle, including Car Ride, Kangaroo, Tree Swing, Rock-a-Bye, and Wave, each of which moves the seat in a different pattern. Combined with five speed settings and four built-in sounds, there are over 400 unique combinations available, which matters because different babies respond to different motions and finding the right one often takes trial and error in the first weeks.
The MotionSync feature in the UPPAbaby app takes the personalization further by using your phone's accelerometer to capture your actual rocking motion and replicate it in the swing. That means the specific movement that calms your baby in your arms can be programmed into the swing directly. Bluetooth connectivity allows full control of motion, speed, and sound from across the room without walking over and disturbing a settled baby. The swing is also compatible with Amazon Alexa and Google Home for hands-free voice control.
The MamaRoo is used in over 600 maternity wards, NICUs, and pediatric units in the US, which reflects its standing among healthcare professionals as a safe and effective soothing tool. The five-point harness with a safety stall feature that stops motion if an obstruction is detected provides the structural safety foundation. The soft machine-washable newborn insert supports proper positioning from birth and is removable for cleaning without tools. The seat reclines infinitely between 25 and 45 degrees, accommodating the transition from the fully reclined newborn position through the more upright position for older babies. The included high-contrast toy mobile with detachable spinning balls provides visual stimulation during alert periods.
The MamaRoo runs on an AC adapter with no batteries required, which eliminates the most common operational frustration with motorized swings. It is JPMA Certified and GREENGUARD Gold Certified. ANB Baby also carries the mamaRoo Sleep Bassinet for overnight use and the full 4moms collection. All orders over $45 ship free.

Yes. The MamaRoo is suitable from birth and includes a soft machine-washable newborn insert that supports proper positioning for younger babies. It is approved for use until the baby reaches 25 lbs or 9 months, or attempts to climb out of the seat, whichever comes first.
The MamaRoo is not approved as an overnight sleep surface. The American Academy of Pediatrics recommends that babies sleep only on a firm, flat surface. If your baby falls asleep in the MamaRoo, transfer them to a firm flat sleep surface as soon as possible. ANB Baby also carries the 4moms mamaRoo Sleep Bassinet which is designed specifically for safe overnight sleep.
MotionSync is a feature in the UPPAbaby app that uses your smartphone's accelerometer to capture your natural rocking motion and replicate it in the swing. This lets you program the specific movement that calms your baby in your arms directly into the MamaRoo.
No. The MamaRoo runs on an included AC adapter and plugs directly into a standard wall outlet. No batteries are required, which ensures consistent power and eliminates the most common operational frustration with motorized baby swings.
Yes. The seat fabric and newborn insert are both machine washable and removable without tools. The shoulder and crotch harness pads are also removable for washing.
Yes. The MamaRoo has a touch-sensitive backlit control panel on the unit itself that lets you adjust motion, speed, and sound without the app. Bluetooth connectivity via the UPPAbaby app, Amazon Alexa, and Google Home provide additional remote and hands-free control options.

Standard baby swings use a single back-and-forth pendulum motion. The MamaRoo's patented MultiMotion Technology combines up-and-down and side-to-side movement to replicate the multi-directional motions parents naturally use when soothing a baby in their arms, which is more effective for many babies than a single-axis swing.
