It’s hard to believe, but baby beds are one of the few things in our lives that have remained virtually the same…for over 1,000 years! However, all that is about to change.

Introducing SNOO, the smartest – and safest – baby sleeper ever made.

After 5 years of effort and innovation, we’re proud to have created a truly revolutionary new bed that weaves ancient wisdom with new technology to reduce the #1 stress of new parents: exhaustion.

Half of all new parents get fewer than 6 hours of broken sleep a night – a level of sleep deprivation that causes the same mental impairment as being drunk. But now, Happiest Baby is coming to the rescue.

SNOO was invented by Dr. Harvey Karp, author of the celebrated Happiest Baby on the Block book/video and creator of the 5 S’s, in collaboration with renowned industrial designer, Yves Béhar, and MIT engineers.

This unique baby bed uses smart technology to boost sleep (choosing slow rocking and calming white noise, like your baby enjoyed in the womb) and to calm crying (choosing just the right mix of faster rocking and stronger womb sound…just like an experienced mom or dad).

SNOO helps infants develop healthier sleep habits and helps parents learn to read their baby’s cues, figuring out when crying is a sign of hunger or just a request for a bit more soothing. (SNOO’s rhythmic responses soothe fussing - often in under a minute - but don’t quiet the cries of hunger or discomfort, which lets parents know exactly when their baby needs them.)

Plus, SNOO’s super-easy, 5-second swaddle keeps babies safely on the back! Its special “safety wings” secure to the bed making it impossible for a baby to roll to the stomach. So, no more “2AM panics.” For the first time in history, parents can sleep peacefully, knowing that their baby will stay in the safest position–all night long.

“New parent exhaustion,” Karp noted, “is a national emergency. Sleep deprivation triggers marital stress, postpartum depression, abuse, obesity, accidents and infant sleep deaths. Furthermore, it undercuts the economy by reducing a new parent’s productivity and increasing absenteeism, on-the-job accidents and health care costs. That’s why I felt so dedicated to developing this new way to help babies – and tired parents – sleep better.”

SNOO’s cutting-edge approach is based on Dr. Karp’s discovery of the calming reflex, a highly effective soothing response activated by the 5 S’s, a series of steps that imitate womb sensations. The calming reflex sheds light on previously unexplained phenomena, such as why we fall asleep on planes and trains and are calmed by the sound of ocean waves. And, why infants are soothed with white noise and rocking.

“SNOO is as elegantly simple and organically natural as Dr. Karp’s 5 S’s,” says Yves Behar, founder and Principal Designer at fuseproject. "It had to be easy to use, provide a sense of trust and comfort and fit beautifully into the context of any home. SNOO unlocks the potential that robotic technology has in our lives – packaged inside a beautiful, ultra-safe, comfortable sleeper.”

What parents appreciate most, though, is that this innovative little bed helps moms, dads and babies sleep better through the night. And that makes for a lot of happiest families on every block! 

But don’t just take our word for it! Watch one baby after another drift calmly to sleep in SNOO.
