Newton and Naturepedic are two of the most frequently compared crib mattress brands among safety-conscious parents. Both position themselves as healthier alternatives to conventional crib mattresses, but they take fundamentally different approaches. Newton focuses on breathability through its Wovenaire polymer core. Naturepedic focuses on organic materials with GOTS-certified cotton and a waterproof plant-based surface. This comparison breaks down what actually differs between the two.

Breathability and Core Construction: How They Differ
This is the most significant difference between the two mattresses. Newton’s patented Wovenaire core is made from food-grade polymer that the company describes as 90% free-flowing air and 10% polymer. Newton markets this as a fully breathable mattress, meaning air can pass through the core itself, not just through ventilation channels. The mattress, cover, and core are all designed to allow airflow.
Naturepedic takes a different approach. The Organic Classic Lightweight uses a WaveSupport core (a non-spring support structure) surrounded by layers of GOTS-certified organic cotton. Naturepedic’s breathable model features a 3D lattice cover designed to promote airflow at the sleep surface, but the core itself is a traditional padded construction rather than an open-air design. The standard Classic model uses a waterproof sugarcane-based surface instead.
For parents whose primary concern is airflow through the mattress itself, the Newton’s open-cell polymer design is structurally distinct from any cotton-based mattress. For parents whose primary concern is organic materials and avoiding synthetic components, Naturepedic’s GOTS-certified organic cotton and plant-based waterproofing may carry more weight.
Washability and Maintenance: How They Differ
Newton’s most distinctive feature may be its full washability. The Wovenaire core can be rinsed in a bathtub or shower, and the cover is machine washable. Newton is one of the only crib mattresses where the entire mattress (not just the cover) can be washed. This can be a meaningful practical advantage during diaper blowouts, spit-up incidents, or illness.
Naturepedic’s cover is removable and machine washable. The waterproof surface on the Classic model means most spills and messes can be wiped clean without removing the cover at all. However, the organic cotton core cannot be washed. If liquid penetrates past the waterproof surface, the interior cotton layers may absorb moisture. The waterproof barrier is designed to prevent this, but it is a structural difference worth noting.
In practice, parents who prioritize easy deep-cleaning may lean toward the Newton. Parents who prefer a wipe-and-go surface for everyday messes may find Naturepedic’s built-in waterproofing more convenient for daily use.
Certifications and Materials Philosophy: How They Differ
Both mattresses carry GREENGUARD Gold certification, meaning they have been independently tested for low chemical emissions. Beyond that, their certification profiles diverge.
Naturepedic holds GOTS (Global Organic Textile Standard) certification for its cotton materials and MADE SAFE certification, which screens for known harmful chemicals. The company emphasizes organic sourcing throughout its supply chain. The waterproof surface is made from non-GMO sugarcane rather than vinyl or PVC, and Naturepedic states that no glues or adhesives are used in the waterproof layer.
Newton’s Wovenaire core is made from food-grade polymer, which is synthetic. It does not carry organic certifications because the core material is not an organic substance. Newton’s pitch is not “organic” but rather “breathable and washable.” The cover uses a Spacer fabric that Newton describes as breathable and removable.
These are genuinely different philosophies. One prioritizes organic and natural materials. The other prioritizes engineered breathability and washability. Neither approach is objectively superior. The right choice depends on which attributes matter more to your family.
What Parents Are Saying
About the Newton Original
Common praise: Breathability is the most frequently cited positive across retailer reviews. Parents describe peace of mind knowing the mattress allows airflow. The washable core is the second most common praise point, particularly from parents dealing with frequent messes. Several reviewers note that the mattress is lighter than expected at 14 lbs, making sheet changes easy.
Common complaints: The most frequent criticism is that the Newton feels different from a traditional mattress. Some parents describe it as having a slightly “crunchy” or “plasticky” feel compared to cotton or foam mattresses. A smaller number of reviewers mention that the non-waterproof model requires more frequent cover washing since spills can reach the core. Some parents feel the price is high relative to what appears to be a simple construction.
About the Naturepedic Organic Classic Lightweight
Common praise: The organic materials and certifications are the top positive theme. Parents who specifically seek out non-toxic nursery products frequently cite the GOTS and MADE SAFE certifications as deciding factors. The built-in waterproof surface is praised for practical daily use. At approximately 11 lbs, the lightweight model is easy to lift for sheet changes.
Common complaints: Some parents note that the “lightweight” model feels thinner or less plush than expected, though this is by design for infant safety (firm sleep surfaces are recommended by the AAP). A few reviewers mention the waterproof surface can feel warm in hot climates. The non-breathable core (compared to Newton’s open-air design) is occasionally cited as a concern by parents who prioritize airflow.

Who Might Prefer Which
- The Newton Original may be a better fit if you: prioritize maximum airflow through the mattress core, want the ability to wash the entire mattress (not just the cover), or prefer a lightweight mattress that is easy to handle during sheet changes.
- The Naturepedic Organic Classic Lightweight may be a better fit if you: prioritize organic and GOTS-certified materials over synthetic alternatives, want a built-in waterproof surface for easy daily cleaning, or value the MADE SAFE certification and a chemical-screening approach to product safety.

FAQ
Can a baby breathe through the Newton crib mattress?
Newton’s Wovenaire core is designed to allow air to pass through the mattress structure. The company states that the core is 90% air and 10% food-grade polymer. Independent testing by the Sleep Foundation (2026) confirms airflow through the core. That said, the AAP recommends that all infants sleep on their backs on a firm, flat surface regardless of mattress breathability. No mattress eliminates the need for safe sleep practices.
Is the Naturepedic waterproof surface made from plastic?
Naturepedic uses a waterproof surface made from LDPE (low-density polyethylene) derived from non-GMO sugarcane. This is a plant-based plastic alternative, not vinyl or PVC. Naturepedic states that no phthalates, glues, or adhesives are used in the waterproof layer.
Do both mattresses fit standard cribs?
Yes. Both are designed for standard-size cribs with interior dimensions of approximately 52″ by 28″. Federal regulations require standard crib mattresses to be at least 51.625″ by 27.25″ and no more than 6″ thick. Both the Newton and Naturepedic fall within these requirements.
Which mattress is lighter?
The Naturepedic Organic Classic Lightweight weighs approximately 11 lbs. The Newton Original weighs approximately 14 lbs. Both are lighter than traditional innerspring crib mattresses, which often weigh 15 to 25 lbs.
Are Newton and Naturepedic mattresses worth the premium price?
Both are priced above entry-level crib mattresses. Whether the premium is worthwhile depends on which features matter to you. If washability and breathability are your top priorities, the Newton’s construction is unique in the market. If organic certification and waterproofing are more meaningful to your family, Naturepedic’s materials and certifications are among the most extensive in the category. Budget crib mattresses that meet CPSC safety standards can also be perfectly safe choices.
