The Newton Crib Mattress is a firm (7) model for infants and toddlers that’s manufactured by Newton Baby. Founded in 2015, Newton Baby aims to help babies sleep more safely and comfortably. In addition to crib mattresses, Newton Baby makes crib-sized sheets and covers, crib and twin-sized mattress pads, and swaddles.
Three crib mattress options are available: the Original, the Essential, and Waterproof. All three are made of a unique polymer support core surrounded by a removable polyester cover. Newton Baby’s proprietary support core material consists of 90% air and 10% food-grade polymer. Because of its airy construction, the Newton Crib Mattress is extremely breathable.
We’ll focus primarily on the Original Newton Crib Mattress but also cover basic information about the Essential and the Waterproof styles. The Newton Crib Mattress is an attractive option to parents looking for a firm, breathable model for their infant or toddler. We’ll cover details of the mattress’ pricing, construction, and performance to help you determine if it’s a good choice for your family.

TEST LAB RATINGS
How the Newton Crib Scored
Temperature Control8.0/10
Compared to most foam beds, the Newton Crib Mattress goes above and beyond in terms of temperature control. Parents generally don’t have to worry about their infant or toddler becoming sweaty or overheating on this mattress.
Although it may be classified as a foam model, the Newton Crib Mattress consists of Wovenaire, which is 90% air and 10% food-grade polymer. Air pockets spread throughout make the mattress highly breathable. Cooling air circulation through these pockets prevents body heat from becoming trapped within the mattress as the baby sleeps.
Ease of Movement6.5/10
Movement on top of the Newton Crib Mattress is very easy, primarily because of the mattress’ firmness and materials. The mattress rates 7 out of 10 on the firmness scale, making it a firm bed. As a result, infants and toddlers lie on top of the bed rather than sink into it. The mattress materials don’t “hug” the body, so there’s little to no resistance when an infant tries to move around on the surface of the mattress.
In addition to making movement easy, a firm mattress is safer for infants because it doesn’t conform as much to the body.
Durability6.0/10
The proprietary polymer used in the Newton Original Crib Mattress’ support core will likely prove about as durable as polyfoam, with an expected lifespan of at least six years. Given that babies generally leave their crib or convertible bed within two to three years, the mattress could potentially hold up for more than one child.
Who it Fits
Fit by Sleep Position and Body Weight
Sizes, dimensions and weights
The Newton Crib Mattress is well-suited for virtually all infants and toddlers. This model provides excellent support and comfort for young sleepers under 130 pounds regardless of their sleep position preferences.
Side Sleepers
Toddlers who prefer sleeping on their sides should enjoy good support that promotes proper spinal alignment when lying on the Newton Crib Mattress. Their weight should also be relatively evenly distributed across the surface, limiting pressure buildup.
Back Sleepers
Generally, parents are advised to have infants sleep on their backs to reduce the risk of SIDS. The Newton Crib Mattress is an excellent choice for back sleepers. Its firmness provides needed support while also feeling comfortable for young sleepers.
Stomach Sleepers
To reduce the risk of SIDS, experts typically warn against placing infants on their stomachs to sleep. Toddlers that do so, however, should get the support they need to maintain alignment throughout the night.
