Meet Lullabee
The Crib Mattress that teaches better sleep
The journey to great sleep starts now. Lullabee's mission is to nurture independent sleep.
How does it work?
Lullabee responds automatically to your child’s needs and adjusts as your child grows.
What to expect:
When Lullabee detects your child is awake and crying, it helps soothe with gentle vibration and calming sound. The support increases the longer your child is awake. Once asleep, Lullabee slowly decreases the support and then tapers off completely.
Phases:
Phase 1 (Support Phase): Lullabee increases the level of soothing rhythms as needed. As your child grows and begins falling asleep quickly and easily, Lullabee automatically transitions to Phase 2.
Phase 2 (Wean Phase): Lullabee gradually decreases the support level over several days to weeks. If your child’s sleep worsens, it automatically goes back to Phase 1. There is no guesswork for parents – Lullabee handles everything automatically.
Lullabee requires no input from the caregiver.
Who Should Use it?
Lullabee is designed to meet standard crib mattress safety specifications and is safe to use as early as the newborn phase. Please check your crib manufacturer’s safety specifications for height and weight requirements.
Who Shouldn’t Use it?
Children with medical conditions that cause sensitivity to vibrations or sounds should not use Lullabee. Consult your child's physician if you have any concerns.
Please see our FAQ section for more information.

Caring for Lullabee
Washing Lullabee:
Outer cover: Lullabee’s outer cover is waterproof and can be removed for washing. Please wash in cold water on a gentle cycle and allow it to air dry.
Inner cover: The inner cover is a mandatory fire retardant and should never be removed. Removing the inner cover is a safety hazard and voids Lullabee’s warranty.
Storage:
When not in use, store Lullabee in a temperature-controlled environment. Avoid exposure to water or excessive heat. Remove the battery while in storage and store it separately.
Battery
Battery Life:
Lullabee comes with a pre-charged battery that lasts around three weeks, or longer if Lullabee is powered off when not in use. If the battery life falls below 15%, the power button will briefly display a solid orange light when first turned on or pressed. This light will not turn on spontaneously to avoid waking your sleeping child. The app will also alert you when the battery life is below 15%, but you must open the app to receive this notification. This prevents unwanted alerts from waking you during the night. Extra batteries can be purchased through Lullabee.com.
Usage:
Lullabee can remain powered on continuously. It will automatically enter a deep sleep mode to conserve battery life and will awaken when your child moves or when the middle power button is pressed. For maximum battery life, turn off Lullabee by pressing and holding the power button for more than 3 seconds when not in use.
Charging:
Only use the supplied charger to recharge the battery. LED lights on the battery indicate the level of charge, and it takes approximately 4 hours to reach a full charge. The final light will stop blinking when the battery is fully charged.
Disposal:
Dispose of old batteries promptly and in accordance with local laws and regulations.Warning:
- Do not touch contacts together.
- Do not demolish or open battery.
