Key takeaways
- The SNOO has FDA De Novo authorization (DEN210039) to facilitate a back-sleeping position, for babies from birth to 6 months who can't roll over consistently. The FDA's summary says it has not directly demonstrated a reduction in SIDS or SUID.
- The HALO BassiNest 3.0 lists a 20 lb limit and says to stop when baby pushes up on hands and knees. The SNOO is listed to 33 lb or 6 months.
- HALO says all U.S. BassiNests comply with 16 CFR 1218 (ASTM F2194) and carry JPMA certification. We found no FDA authorization for a HALO bassinet.
- We found no CPSC recall of a HALO or Happiest Baby bassinet in our October 16, 2026 search. HALO Innovations did have a 2013 recall of wearable blankets with pink satin flowers.
- The AAP says a firm, flat surface, on the back, in your room, with nothing else in the bed is the plan for any bassinet, and that no commercial device has been shown to reduce SIDS.
At a glance
Happiest Baby SNOO
Suits: Families who want a motorized bassinet for the first months, with FDA De Novo authorization for keeping a baby on their back, and who are fine with a 6-month limit or a rental.

HALO BassiNest Swivel Sleeper 3.0
Suits: Parents who want a bedside bassinet that swivels over the bed and lowers a wall for feeds and postpartum recovery, and don't need a motorized bed.
- Strength: 360-degree swivel and lowering wall bring baby to you without getting up, per HALO
- Strength: Height adjustable for beds up to 30 inches, per HALO
- Strength: HALO lists compliance with 16 CFR 1218 (ASTM F2194) and JPMA certification
- Trade-off: Stop at 20 lb or when baby pushes up on hands and knees, whichever comes first
- Trade-off: No FDA authorization stated on the page we checked
- Trade-off: 34 by 34 inch base, so it needs floor space beside the bed
The SNOO and the HALO BassiNest both promise easier nights in the first months, but they work in opposite ways. The SNOO rocks and soothes your baby with a motor. The HALO BassiNest keeps your baby close by swiveling over your bed. If you're weighing SNOO vs HALO BassiNest, the biggest differences are FDA status, weight limits and whether you want motion at all.
This page compares them from the makers' pages, the FDA's decision summary and federal and AAP safe sleep guidance. We research products; we don't test them, and we don't list prices. HALO makes several BassiNest models, so we compared the Swivel Sleeper 3.0, which is the base version.

What does the FDA say about the SNOO?
The FDA granted the SNOO a De Novo authorization, number DEN210039, as an infant supine sleep system. The indication is that it is "intended to facilitate a supine position during sleep." It is for home use by caregivers of infants from birth to 6 months who are not yet able to roll over consistently [1].
Then the limits, in the FDA's words [1]:
"The SNOO is demonstrated to facilitate a supine position during sleep; however, the SNOO has not directly demonstrated a reduction in the incidence of SIDS/SUID."
It also says not to use the SNOO if the infant can push up on hands and knees, can roll over consistently, or has reached 6 months [1]. Happiest Baby lists a maximum weight of 33 lb [2]. For the full breakdown of the SNOO's FDA language, see our Cradlewise vs SNOO comparison.
Is the HALO BassiNest FDA approved?
We found no FDA authorization for a HALO bassinet. HALO's pages list compliance with the CPSC bassinet rule and JPMA certification, and neither the 3.0 nor the 4.0 Air page mentions the FDA [4][5]. We also didn't find a De Novo decision for HALO in our search.
That isn't a safety finding. A bassinet doesn't need FDA authorization to be sold, and HALO doesn't claim it. It does mean HALO can't point to the kind of FDA indication the SNOO has. Ask HALO directly if this matters to you.
How are the weight limits different?
This is the clearest practical gap.
- HALO BassiNest 3.0: stop when baby pushes up on hands and knees or reaches 20 lb, whichever comes first [4]. For the newer 4.0 Air, HALO's FAQ also lists signs of rolling or sitting [5].
- SNOO: stop at 6 months, 33 lb or when baby pushes up on hands and knees, whichever comes first [1][2].
Plan your next sleep space either way. Our crib vs bassinet guide covers the switch. Neither maker's limit is a promise about development, so move up when the label's limit or milestone arrives, not when the calendar says so.
Motorized rocking or a bed you move by hand
The SNOO does the rocking. Happiest Baby describes gentle rocking and soothing for naps and nights, plus a "5-second swaddle" Sleep Sack that clips to the bed [3]. The Sleep Sack is the restraint the FDA decision depends on, so the SNOO is meant to be used with it [1].
The HALO 3.0 has no motor. Its features are a 360-degree swivel that moves baby over your bed and a lowering wall for feeds and lifting, which HALO's 4.0 page calls ideal for postpartum recovery [5]. HALO also sells a soothing 3.0S with vibration and sounds and a connected 3.0 with an app [12]. We compared the base model, so check those pages for their specs.
Rent or buy
Happiest Baby says SNOO rentals are ordered directly from it or from an authorized partner, and that renters get the free Premium subscription for the rental period plus one month. Buyers after July 15, 2024 get it free for 9 months [3]. Renting suits a bed you'll only use for a few months.
We didn't find a rental program on HALO's pages. It sells the BassiNest outright, and the base 3.0 has no app or plan on the page we checked [4].
What federal rules apply?
Bassinets sold in the U.S. must meet the CPSC's bassinet and cradle rule, 16 CFR 1218, which incorporates ASTM F2194 [6][7]. HALO says all U.S. BassiNests comply with it and also carry JPMA certification, and that the 4.0 Air meets ASTM standards and is verified by the Baby Safety Alliance [4][5]. The rule applies to every bassinet, motorized or not, so a smart or swivel label doesn't change the baseline.
What the AAP says
The AAP's advice is the same for both:
- Put your baby on their back for every sleep, on a firm, flat surface, with a fitted sheet and nothing else [8].
- Room-share without bed-sharing, ideally for at least the first 6 months [8].
- Avoid commercial devices that claim to reduce SIDS risk. The AAP says there is no evidence that any of these devices reduce these deaths, and that they may give a false sense of security [9].
A bassinet that swivels over your bed is still a separate sleep space. Don't let baby sleep on you or in your bed. HALO's own pages say never to use loose blankets, bumpers, pillows or positioners in the BassiNest [4].
Who each one fits
The SNOO may fit if you want motion built in, are comfortable with a rental, and want the FDA-authorized back-sleeping design. The HALO BassiNest may fit if you want to reach your baby without standing up, you're recovering from birth and want less bending, and a 20 lb limit works for you.
Skip both if the cost doesn't fit or you only want a safe place to sleep. Any bassinet that meets CPSC standards works. See our best bassinets and best cribs guides, or check whether you qualify for a free crib.
Recalls and safety
We searched the CPSC recall database on October 16, 2026 for SNOO, Happiest Baby, HALO and BassiNest. We found no recall of a SNOO or a HALO bassinet [11]. In 2013, Halo Innovations recalled about 27,000 HALO SleepSack wearable blankets with pink satin flowers, because petals could detach and choke an infant. That was a blanket, not a bassinet [10].
Search results change, so check the CPSC recall list and our bassinet recalls page before you buy or take a hand-me-down. Always stop at the limits on the label, keep the bed on a flat surface, and don't add anything to the sleep space.

Questions people ask
What is the difference between the SNOO and the HALO BassiNest?
The SNOO is a plug-in bassinet that rocks and plays white noise, used with a Sleep Sack that clips in, for birth to about 6 months [2][3]. The HALO BassiNest Swivel Sleeper 3.0 is a bedside bassinet with a swivel and a lowering wall that you move by hand, listed to 20 lb [4]. HALO sells vibrating and app-connected versions separately [12].
Is the SNOO FDA approved?
The FDA granted the SNOO a De Novo authorization (DEN210039) as an infant supine sleep system, Class II [1]. That covers facilitating a back-sleeping position. The FDA's summary also says the SNOO has not directly demonstrated a reduction in the incidence of SIDS or SUID [1].
Is the HALO BassiNest FDA approved?
Not that we could find. HALO's product pages list compliance with the CPSC bassinet rule, 16 CFR 1218, and JPMA certification, and say nothing about the FDA [4][5]. A bassinet doesn't need FDA authorization to be sold. Ask HALO directly if this matters to you.
Has the HALO BassiNest been recalled?
We found no CPSC recall of a HALO BassiNest or any HALO bassinet when we searched on October 16, 2026 [10][11]. HALO Innovations did recall about 27,000 HALO SleepSack wearable blankets with pink satin flowers in 2013 because petals could detach and choke a baby [10]. That was a blanket, not a bassinet.
How long can a baby use the HALO BassiNest or SNOO?
The HALO BassiNest 3.0 says to stop when baby pushes up on hands and knees or reaches 20 lb [4]. The SNOO's limit is 6 months, 33 lb or pushing up on hands and knees, whichever comes first [2][3]. Follow the manual over any general age.
Do smart bassinets prevent SIDS?
No bassinet has been shown to. The AAP says to avoid commercial devices that claim to reduce SIDS risk, because there is no evidence that any of them do [9]. Back sleeping on a firm, flat surface in your room is the plan with either one [8].
