About SNOO Baby Bassinet and Sleeper

Created by celebrated pediatrician
Dr. Harvey Karp (Happiest Baby on the Block),
SNOO is a smarter and safer baby bed!

For the first 6 months, like an extra set of hands, SNOO boosts sleep with gentle rocking and soothing…for all naps and nights. Its quick response often calms upsets in under a minute. And our “5-second swaddle” reduces dangerous rolling.

Why SNOO is Parents' Favorite Bassinet


    Adds 1-2 hours of sleep per night with constant calming womb-like motion + sound


    Automatically sleep trains, making it easy to transition to a crib…with little need to

  • YOUR 24/7 HELPER

    Your extra set of hands, SNOO helps whenever you need a break: to shower, work, cook, or sleep


    Automatically responds to your baby’s fussing…even when you’re asleep


    Helpful settings, daily sleep report, and tips from Dr. Karp


    Secure swaddling prevents rolling to an unsafe position during sleep


    Soothes upsets with increasing motion + sound, often calming crying in under a minute

SNOO is the first—and only—medical device to receive De Novo authorization from the FDA for its ability to keep sleeping babies safely on their backs. Babies who are placed on the back for sleep are at a lower risk of SIDS/SUID.

Pre-Loved SNOO FAQs

What should I consider when buying a used SNOO Bassinet?
Most used SNOO sellers cannot guarantee the quality of cleanliness of a used SNOO, which is why we recommend buying a Certified Pre-Loved SNOO directly from Happiest Baby. Unlike a used SNOO you might find on Facebook Marketplace, Craigslist, or eBay, every Certified Pre-Loved SNOO has been through our 5-step refresh and reconditioning process and has been rigorously inspected for safety, cleanliness, and quality!

How can I ensure the safety of a used SNOO Bassinet?
The best way to ensure the safety of a used SNOO is to purchase direct from Happiest Baby! Our Certified Pre-Loved SNOOs are inspected for safety and quality so that they reach you in like-new working condition!

Where can I buy a used SNOO?
The only place to buy a Certified Pre-Loved SNOO is at HappiestBaby.com! When you purchase your secondhand SNOO directly from Happiest Baby, you know that your SNOO is in good working condition, has been sanitized and inspected, and comes with a 1-year warranty as well as all new accessories.

Can I buy a used SNOO through insurance?
Not at this time, but we hope that SNOO will be covered by insurance in the future! In the meantime, thousands of parents get free 6-month SNOO Rentals as an employee benefit. For more information, please reach out or have your HR or Benefits Manager connect with corporaterental@happiestbaby.com.

What is included with a used SNOO?
Every Pre-Loved SNOO bought through Happiest Baby comes with:
  • New mattress and water-resistant cover
  • 1 new 100% organic cotton Ivory SNOO Sheet
  • 1 new Small Ivory SNOO Sack
  • 1 new Medium Ivory SNOO Sack
  • Access to sleep consultants, 7 days a week
  • Access to our App, complete with daily sleep reports, tips from renowned pediatrician Dr. Harvey Karp, and more
  • 1-year warranty

Is there a gently used SNOO or are all used SNOOs the same?
When you buy a Certified Pre-Loved SNOO, you have the assurance that your SNOO has been thoroughly inspected and returned to excellent working condition. Happiest Baby cannot guarantee the condition of used SNOOs purchased elsewhere.

Can I use a used SNOO Bassinet for multiple children?
Yes! SNOO is built to last for multiple children! One benefit of buying a Pre-Loved SNOO instead of renting SNOO is that you can use it for multiple children. If you’re only using SNOO for one baby, a SNOO Rental might be a better option for your family. Learn about SNOO rentals.

Should I buy a used SNOO for sale on Facebook Marketplace, Craigslist, or eBay?
Buying a used SNOO on Facebook Marketplace, Craigslist, or eBay comes with unknowns and risks, such as:
  • Unauthorized used SNOOs aren’t necessarily cleaned and sanitized.
  • There’s no way to know if your SNOO is in good working condition when you buy a used SNOO through an unauthorized seller.
  • Unauthorized secondhand SNOOs don’t come with a warranty or return policy.
  • Unauthorized SNOO sales are vulnerable to scams.
On the flip side, when you buy a Certified Pre-Loved SNOO from Happiest Baby, your used SNOO:
  • Has a 1-year warranty
  • Has been thoroughly cleaned and sanitized
  • Has been reconditioned to like-new condition
  • Has been inspected for quality and safety
  • Comes with all new soft goods

What is the average lifespan of a SNOO Bassinet?
SNOO undergoes rigorous testing with well over 10 million cycles—that’s enough to be in motion for more than 14 hours a day, month after month! (For context, most baby swings only last a fraction of that.)

What can I expect when my used SNOO arrives?
Every Pre-Loved SNOO comes in the same pristine packaging as a new SNOO or SNOO Rental and includes over $100 worth of all new soft goods (1 SNOO Sheet, 1 Small SNOO Sack, and 1 Medium SNOO Sack). Because our Pre-Loved SNOOs come from our well maintained rental fleet, you might notice rental paperwork in your Pre-Loved SNOO box (you can ignore it and throw it in your recycling!).

Can I return my Pre-Loved SNOO?
Yes! When you buy through Happiest Baby, you have 30 days to return your used SNOO from the day it’s delivered, but each Pre-Loved SNOO return will incur a $199 restocking fee. Please reach out to customercare@happiestbaby.com to start a return.

Does a Certified Pre-Loved SNOO come with a warranty?
Yes! When you buy a used SNOO through Happiest Baby, you can rest easy knowing that your SNOO is under a 1-year warranty. If your Pre-Loved SNOO isn’t working properly during the 1-year warranty period, contact our Customer Care team. Learn more about our warranty at happiestbaby.com/pages/legal.

Life changing aka sleep matters!

My daughter was sleeping in1-3 hour stream he’s for the first 3 months. I rented her a snoo to try and baby slept 7 hours the first night!

Hi there,

We're overjoyed to hear that your little one is getting longer sleep stretches with SNOO! Thanks for including us on your journey!

Snoo Rental is Awesome💯

Having the ability to rent a Snoo is such a great option. Very happy with it, the items that came with it, and the packaging and delivery were great too! Month to month rental is great as our Grandbaby will outgrow it soon! I would highly recommend!!

Hi there,

We're overjoyed to hear that SNOO Rental has been a great choice for your family! For the safest sleep, we suggest using SNOO for the first 6 months. So excited to be on this journey with your family!

Thanks for sharing & happy SNOOzing,

Sonja from the Happiest Baby Team

Best Sleeping Bassinet Ever Invented

I am so happy that I was able to provide the SNOO Smart Sleeper for my grand-daughter's 2 week visit. She has been using the SNOO since she came home from the hospital. I'm totally amazed at what a GREAT sleeper she is. Her parents are worried when she outgrows it, will she continue being a good sleeper. I wish I had this bassinet when my sons were newborns. In fact, I wish there was an adult version of this sleeper.

Hi Darleen,

Reviews like yours truly make our day! We’re so happy to hear that SNOO has helped your granddaughter’s sleep since day 1!

There’s no need to worry about the transition! Babies naturally outgrow the need for motion around 5-6 months which is when they’ll be ready to graduate to the crib. Plus, our Weaning feature in the App makes the transition easy-breezy. Our team is available 7 days/week at support.happiestbaby.com to provide sleep support if needed. So excited to be on this journey with your family!

Thanks for sharing & happy SNOOzing,

Sonja from the Happiest Baby Team

Highly Recommend!

The Snoo has been a game changer! My LO fights the swaddle a little bit, but once clipped in will fall asleep almost instantly. If she doesn't, she'll usually quickly drift off. Babies are LOUD and wake up a lot, so having the Snoo gently get her back to sleep without me having to get up is huge. Before the Snoo she had only independently slept for about 30 minutes- after just 2 weeks we're up to a 6 hour stretch. I feel like a new person finally being able to get some rest and not being nap trapped all the time! The Snoo arrived a day before it was supposed to, instructions were easy to follow and I was able to quickly set it up. The only "negative" is that I wish that it came with a printed card of what the different levels mean. The option to rent is amazing-- renting directly from the company gives me a peace of mind, and allows us to check it out before deciding if we want to purchase or not.

Hi Tara,

Thank you so much for taking the time to leave such a thoughtful review! It means the world to us knowing SNOO supports your family in getting the rest you deserve! Being a new parent is a lot of work and we're happy to make things a little easier for you and safer for your little one.

Regarding SNOO levels, you can find some helpful info in the Using SNOO section of our user guide. And if you have any other questions during your SNOO journey, please connect with us at support.happiest.com!

Happy SNOOzing,

Sonja from the Happiest Baby Team
