Newton Baby: The Science Behind the Safety
Newton Baby was created out of the founders’ mission to offer the safest, healthiest, and best sleep products for babies. As veterans of the sleep industry (and concerned parents themselves), they had a keen understanding of the market and where current offerings came up short. Thus, the “revolution-airy” Newton Crib Mattress was born.
The main component of the Newton Crib Mattress is Wovenaire, a material comprised of food-grade polymer and 90% air by volume. Its unique, first-of-its-kind composition allows for the highest level of airflow for babies to breathe easily and sleep soundly, thus giving parents the peace of mind they need for the only periods during which their little ones aren’t under continual surveillance.
Although experts recommend that babies sleep on their backs, rollovers inevitably occur. Traditional crib mattresses can pose a suffocation risk, and thus Newton Baby sought to create a safer sleep environment in the event of these particular instances.
Study #1: Suffocation Risk
To ensure that the product fulfilled its purpose and reached the highest possible standards, Newton Baby submitted a sample crib mattress to a multinational, CPSC-accredited inspection/product testing laboratory for review in 2015 to gauge the risk of infant suffocation. They used a mannequin with the weight and respiratory capabilities of a six-month-old baby, and introduced three competing crib mattresses in addition to the Newton as benchmarks.
The Newton Crib Mattress showed the lowest risk of suffocation, which was half of that of two competitors, while the third showed an unusually high risk of suffocation. (Suffocation potential took into account the pressure for normal airway flow resistance and elastic recoil of the lungs and chest when the mannequin was face down and breathing through each of the mattress samples.) Additionally, the Newton measured significantly below the limit for a surface to be potentially fatal on account of airway obstruction (15 cm H2O), with an average measure across 30 tests at 2.12 cm H2O. (It is worth noting that the normal rate of unhindered breathing for a newborn is 2.0 cm H2O.)
During the final assessment stages, the Newton Crib Mattress was compared to being “just like breathing” by the technicians at the lab analyzing the data. The findings were then shared with a leading neonatologist (doctor specializing in infant care), who is also an expert in infant breathing disorders. The doctor concurred that the Newton Crib Mattress posed a considerably low risk of suffocation.
Study #2: Carbon Dioxide Rebreathing
Another study was conducted in the same year by the same inspection/product testing laboratory to measure carbon dioxide rebreathing rates. Carbon dioxide rebreathing increases respiratory effort, and the rebreathing of exhaled air is considered to be one possible cause of Sudden Infant Death Syndrome, commonly known as SIDS.
The researchers used a mannequin with a simulated respiratory system akin to that of a one-month-old baby, comparing its carbon dioxide rebreathing patterns on the Newton sample paired with a muslin cotton sheet along with that of a conventional waterproof mattress with a muslin cotton sheet; a long-haired sheepskin blanket; and a bean bag (mimicking a sinkable surface with waterproof lining).
The research showed that the Newton Crib Mattress significantly had the lowest amount of carbon dioxide retention, thus proving to be a “very benign” surface for a resting newborn. The bean bag proved to be the biggest hazard for carbon dioxide rebreathing, followed by the sheepskin blanket and then the non-Newton waterproof mattress.
The findings were then shared with the same expert neonatologist from the previous study. After reviewing the research, the doctor confirmed that the Newton Crib Mattress did not pose a significant hazard in terms of breathability for infants, while also noting that it posed a significantly lower risk of carbon dioxide rebreathing than a conventional crib mattress.
Study #3: Suffocation Risk for the Newton Crib Mattress Pad
In 2017, Newton Baby introduced its crib mattress pad to the market, and in the same year submitted a sample to the same inspection/product testing laboratory involved in the previous two studies. This time, a mannequin with a mechanical lung system akin to that of a one-year-old was used to gauge the risk of suffocation on the mattress pad, which was fitted over a Newton Crib Mattress sample.
The researchers conducted five trials with the mannequin face down, breathing through the mattress pad. Similar to the first study with the Newton Crib Mattress, the Newton Crib Mattress Pad showed a very low risk of suffocation. The Newton measured significantly below the limit for a surface to be potentially fatal on account of airway obstruction (15 cm H2O), measuring at 2.46 cm H2O, 2.05 cm H2O, 1.92 cm H2O, 2.42 cm H2O, and 1.87 cm H2O across the five trials.
