Zed soothes babies to sleep by mimicking the feeling of being in the car. The clever technology has been designed to recreate the soothing low-frequency vibrations of a car’s suspension and revving engine that are known to send babies to sleep. Includes Red Glow Night Light. 6 calming vibration modes (3 static vibration speeds + 3 additional modes) let you find the perfect virtual car ride for your baby, helping to improve their nap lengths. Works on any type of mattress, such as a Moses basket, cot, pram, bed or even a feeding cushion. As babies tend to sleep in 45-minute cycles, Zed was designed to fade out gently after 1 hour, by which time your baby will be in their second sleep cycle and a deeper sleep. Night Light. Model ZED01. 2 x AA . EAN: 5060539650027. WARNING(S):Only for domestic use.
