Newton Baby Crib Mattress, Infant & Toddler, Dual-Layer, Breathable & Washable, 5.5 inch, Sky Blue Review (2026)

Who this mattress is built for

This mattress fits parents who prioritize breathability and easy cleaning over a lower price point, and who are willing to pay more upfront for a core they can rinse rather than one they can only wipe down. Because Newton designs it as a dual-stage mattress, it also suits a family that wants to buy once and keep the same mattress through the toddler bed stage rather than replacing it partway through. The sky blue cover leans toward a blue or gender-neutral nursery palette, so a parent set on a different color scheme should check Newton's other cover options first. The dual-stage design also appeals to a family that would rather avoid buying and disposing of a separate toddler mattress once the crib stage ends.

What the Wovenaire core and dual-layer cover actually are

Newton's core is built from 90 percent air and 10 percent food-grade polymer in an open-weave structure, with no foam, glue, latex or springs, according to Newton's own product listing. The mattress measures about 52 by 28 by 5.5 inches to fit a standard full-size crib. The cover is a dual-layer quilted design that zips off for washing separately from the core, and the mattress carries GREENGUARD Gold certification, meaning it has been independently tested for low chemical emissions against that program's standards. Newton sells the same core under other cover colors as well, so sky blue is a style choice rather than a functional difference from the rest of the line.

Living with it: cleaning and the infant-to-toddler stage

Newton's washing instructions call for zipping the cover closed, machine washing it cold and alone on a delicate cycle, then tumble drying on low without bleach. The core itself can be rinsed in the shower or with a hose using soap and cool water, then air dried standing up in a well-ventilated spot out of direct sunlight. Because the same mattress is designed to work through the toddler bed stage without flipping, there is no need to buy a second mattress when the crib converts, which offsets some of the higher upfront price over several years of use. With no foam or springs to break down, the core also tends to hold its shape well as a toddler grows heavier.

Trade-offs and how it compares with rivals

A Graco Dual-Comfort or Graco Ultra 2-in-1 mattress offers GREENGUARD Gold certification at a noticeably lower price, using a firm-and-soft dual-sided foam core rather than an open-weave structure. The trade-off against those rivals is price: a Wovenaire core costs more than certified foam, in exchange for a core that rinses clean in the shower rather than only wiping down, which matters more to a household dealing with frequent leaks or spit-up than to one that mainly wants a solid, budget-friendly crib mattress from day one without planning around a rinseable core.

Verdict and who should pick something else

For a parent who wants a rinseable core, a dual-stage design that lasts into the toddler years, and GREENGUARD Gold certification, this Newton mattress earns its our score of 9.0 out of 10. A family working with a tighter nursery budget who does not need a washable core should compare it against a certified foam option like the Graco Dual-Comfort, which covers the basic safety certifications at a lower price without the rinse-clean feature, and should still confirm crib rail fit before ordering either mattress. Either option should be paired with a properly fitted crib sheet from the start.
