Sleep Doctor’s take: Newton Crib Mattress

With a core made from an innovative, food-grade polymer called Wovenaire, the Newton Crib Mattress offers excellent breathability and support. Parents can rest easier knowing the mattress meets rigorous safety standards without sacrificing a baby’s comfort.

Newton Crib Mattress: An introduction

Newton Baby focuses on mattresses and other products designed specifically for infants and toddlers. What sets this model apart from other crib mattresses is the brand’s unique Wovenaire technology. Made from a food-grade polymer woven in a pool of water, the mattress’ core is 90% air by volume, giving it exceptional breathability.

What you need to know about the Newton Crib Mattress

The Newton Crib Mattress is designed for safety and comfort. Newton eschews typical crib mattress materials in favor of its Wovenaire technology composed of interlaced polymer fibers. The result is a firm sleep surface that meets federal safety standards and is designed to deliver the support a baby needs for healthy development. 

This mattress comes in three options. Parents can choose from a 4-inch profile and single-layered cover in the Essential, or a 5.5-inch height and double-layered cover in the Original. Newton also sells a 5.5-inch Waterproof option that makes cleaning easier and works well for both infants and toddlers.

Sleeping positions and firmness

While adults can choose between firmness levels when searching for the best mattress for their needs, infants need to sleep on a firm surface. Plush bedding or a too-soft surface can be dangerous for infants under 12 months old. As children graduate into their toddler years, softer mattresses or toppers can be introduced.

Newton Crib Mattress sleeper ratings

Side Sleepers5/5
Back Sleepers5/5
Stomach Sleepers5/5

According to the American Academy of Pediatrics, babies under 1 year old should always be put to sleep on their back. As babies grow into toddlers and their sleep cycles begin to change, their firmness needs and sleep positions also evolve. This makes a versatile mattress that offers consistent support across sleep positions a particularly good choice.

The Newton Crib Mattress’ Wovenaire core offers a firm foundation that creates a safe and comfortable surface for back-sleeping infants, but it has enough give to provide comfort for active toddlers regardless of the position they sleep in.

Our performance ratings

We rated the Newton Crib Mattress’ performance in four key sleep categories using a five-point scale, with 1 being poor and 5 being excellent.

Temperature neutrality

Rating: 5/5

The mattress’ Wovenaire core consists of 90% air and 10% food-grade polymer that’s designed for breathability. Its open structure allows for plenty of airflow, keeping the sleep surface cool and preventing the buildup of heat. The polyester cover is light and airy, complementing the mattress’ permeable construction.


Rating: 3/5

With its emphasis on breathability, the Newton Crib Mattress’ design is lighter and a bit less sturdy than other materials. However, for those looking for a mattress that emphasizes breathability, its less durable design may be a nonissue since most children grow out of their crib mattress within a few years. 

Ease of movement

Rating: 5/5

A firm sleep surface not only helps ensure back-sleeping infants remain safe and supported on the Newton Crib Mattress, it also makes it easier for children over 1 year old to shift and move. This benefits toddlers who are active sleepers.


Rating: 4/5

The Newton Crib Mattress is certified by GREENGUARD Gold, meaning it meets rigorous standards for chemical emissions. This includes volatile organic compounds (VOCs), the tiny particles responsible for most off-gassing odors after unboxing a mattress. While there may still be some detectable smell associated with the mattress’ new materials, this should dissipate within a few days.

What is the Newton Crib Mattress made of?

The Original version of the Newton Crib Mattress features a quilted dual-layer polyester cover. Just below, a viscose encasement creates a natural fire barrier. The Wovenaire core is made from food-grade polymer strands that create a breathable and supportive sleep surface. 

The Waterproof model of the Newton Crib Mattress has an infant side and a toddler side. It includes a thermoplastic polyurethane barrier on the toddler side to accommodate children in the potty training phase.

The Essential is a pared-down model that uses a thinner Wovenaire core and a thinner, single-layer cover.

All components of all versions of the Newton Crib Mattress are washable and certified by GREENGUARD Gold for low chemical emissions.
