The Snoo is a bassinet unlike any other we've tested and thanks to its unique smart features, it came in 3rd place overall and earned it a notable slot for its soothing abilities. This bassinet claims to be a miracle worker when it comes to colicky babies and has helped many a desperate mother with its rocking motion and white noise. While this hefty bassinet is not one you'll be taking with you on weekend trips, or even moving from room to room often, we like that it has a modern, stylish design, and feel that it offers a high level of quality that is meant to last for years. However, this is the most expensive bassinet in the review, beating out the closest competitor by almost 3x. It also emits EMF (which we like to avoid when possible), which is not found in any of the competition. If cost is not a significant factor in your decision, the EMF levels don't concern you, and your baby seems particularly fussy or struggles to stay asleep, then the Snoo Smart Sleeper may be exactly what you need to get consistent quality sleep.

Our Analysis and Test Results
The Snoo (blue) earned impressive metric scores which helped it earn a third-place rank in our tests.
The sections that follow provide details on how the Snoo compares to the competition.
Ease of Use
The Snoo Smart Sleeper earned a 4 of 10 for ease of use.
The Snoo can make your life easier thanks to the unique features it offers, but it is more involved than your average bassinet and may have more of a learning curve in the beginning.
The legs included with the Snoo are not adjustable, so the bassinet height cannot be changed to match the height of your mattress unless you purchase a different set of legs. The level of the baby sleep surface is a few inches lower than your average 25" bed, while the upper rail reaches a few inches higher. This design means you'll need to reach up and over the rail and then below waist level to get your baby without leaving your bed. If this sounds uncomfortable, that's because it probably is. So, while it is possible to reach the baby without getting out of bed, we think you'll find it easier to swing your legs over the bed edge to give the whole operation a bit more stability.
The Snoo is not very portable. At 35.1 lbs, it is the heaviest bassinet in this review, and it does not fold down or come apart for easier transportation. It is not very large, so it can easily fit through door frames and hallways, but the weight may deter you from moving it from room to room.
This "Smart Sleeper" is built around the additional features it offers with the most extras by far of all the bassinets in this review. Perhaps the most notable is the soothing ability of the "wiggly" mattress. A microphone located in the base of the Snoo detects crying and then tells the motor to start working through four increasingly vigorous levels of rocking to soothe the baby, and speaker system automatically chooses one of four levels of white noise. If your baby has not calmed down after three minutes, the Snoo shuts off, as the baby likely needs some human attention. If you prefer to adjust rocking speed and noise level on your own, you can do this through the app. The Snoo app also logs your baby's sleep and keeps track of things like day sleep, night sleep, total sleep, the longest stretch of sleep, and the number of times the baby woke up while in the Snoo.
Included with the bassinet are one fitted sheet and three different sized sleep sacks. The swaddles are created specifically for use with the Snoo with tabs that slide over a hook on either side of the bassinet and keep baby in the center of the mattress, always on their back. Three swaddles, one of each size, are included with the purchase of the bassinet, but we think it is a good idea to purchase an additional sack in each size just in case.
Ease of Setup
The setup process for the Snoo is one of the easiest in the group, earning a 9 of 10 points. Straight out of the box, the bassinet calls for minimal assembly and no tools. The initial setup involves very few steps, of snapping in the legs and hand tightening the bolts that keep it sturdy. The only possible mix up that we foresee is inserting the legs backward. This mistake doesn't affect the functionality of the bassinet, but it looks strange. After assembly, you only need to plug it in and secure the sleep sack for day to day use.
Both the sheets and sleep sack that come with the SNOO are machine washable. Other items in the sleeping area, such as the mattress, mesh sides, and base, can be wiped or spot cleaned with a damp cloth and mild detergent when necessary. The base beneath the mattress is hard plastic and is easy to wipe down, but you may have a bit more trouble with the mesh sidewalls in the case of an extreme blowout.
The Snoo tied with the babybay Bedside Sleeper for the high score of the group with a 10 for breathability.
The sidewalls are breathable double layered mesh fabric that allows for good airflow all the way around the bassinet. Thanks to the clip-in swaddle, the baby is held securely in place, eliminating the chance of a baby rolling or wriggling themselves up against the side.
We were pleased with the sleep surface of the Snoo, and it earned a 9 of 10 in this metric.
The mattress is very stable and fits well in the bassinet. It shifts slightly from top to bottom, but there wasn't enough room for us to squeeze more than one finger between the mattress and the side mesh. It is not attached to the base in any way, but when the baby is clipped in with the sleep sack, it should stay in place well. We found the surface to be the third most firm of the group, being surpassed only by the UPPAbaby Bassinet and Stand and the HALO Bassinest Essentia.
The Snoo earned a 9 of 10 for quality, coming in second in the group. The babybay was the only better scorer, and for a bassinet in this price range, we would expect no less.
The four legs come out from the bassinet and have rubberized foot pads that make it extremely stable. The low center of gravity and heavy weight of the Snoo also help to eliminate the risk of tipping. All odds and ends are tucked away for a simple and stylish, mid-century modern look, and there are no sharp edges, pinch risks, small parts, or a mattress gap to cause worry. The fabric and mesh are snug and fitted, and the other materials have a smooth assembly for a great fit and finish. The mattress adheres to ASTM standards and is still comfortable enough for baby.
This product is well built and should last through multiple children. We think of it more as a long-term investment in the interest of the sleep patterns of you and your future children.
With a 5 out of 10 for eco-health, the Snoo earned a score that is just above average for the group.
On the Happiest Baby website, sleep safety is the priority, but they do not offer much information on the eco-health of their product. After some digging around, we found that the bassinet is JPMA certified and both the sheets and the swaddle sacks are GOTS certified organic materials and the product has no detectable levels of fire retardant chemicals. However, it does have a polyurethane foam mattress similar to all of the other bassinets which aren't ideal for little ones as they off gas to one extent or another.
Unlike any other bassinet, this unit uses Wi-Fi technology to talk with your smartphone or tablet to set up or modify how the Snoo operates. As a result, it emits EMF which your baby is then exposed to. During testing, we got readings of 4.4 V/m on average next to the power button. When using the meter inside the bassinet where the baby will sleep, levels are lower with an average reading of 0.9 V/m. This lower reading is likely a result of the manufacturer design that has a shield plate between the baby and the EMF source. While this level isn't as concerning as some of the wearable movement monitors, it is still a concern if you are trying to avoid or limit EMF exposure.We would love this product if there was a way to use it without EMF involvement like a simple on/off switch you would find on a baby swing. Why does it have to come at the risk of exposing your baby to any level of EMF? We feel this is a product design failure and we hope this is something Happy Baby will address in future versions.
There are a few accessories available for the Snoo on the Happiest Baby website.
- SNOO Organic Cotton Fitted Sheet - An extra fitted sheet to use in case of spit-up messes or diaper blowouts.
- SNOO Sack - A set of three comes with the bassinet, but you will likely want a backup for each size so you can keep them clean.
- SNOO Leg Lifters - These come in a set of two and are meant to slightly elevate the head of the bassinet to a safe incline to help the baby breathe easier and possibly help with reflux.
- SNOO Shorty Legs - These are a shorter version of the legs that come with the Snoo. They lower the bassinet to 10" above the ground and are intended for use when the Snoo is next to a platform bed.
