Baby Brezza Smart Soothing Mat is the only smart portable mat that soothes your baby for better and safer sleep. The Soothing Mat mimics the rumbly sounds and gentle motions of a mother’s womb, which activates your baby’s natural calming reflex developed in utero. You can use the mat anywhere your baby sleeps, which will help your baby sleep safely on her back unlike rockers and swings which encourage babies to sleep on an incline. Choose from 8 different soothing settings (4 vibration levels and 4 heartbeat modes) and 5 timer settings using the FREE app or the buttons on the mat. 1-year limited warranty.
