When it comes to your baby's sleep, there's no room for compromise — and the Newton Original Crib Mattress was built with exactly that in mind. Unlike ordinary crib mattresses, Newton's patented Wovenaire® core allows air to flow freely throughout the entire mattress. This breathe-thru design helps reduce the risk of suffocation according to independent lab test results. The result? A safer, cooler, more comfortable sleep environment that helps your baby sleep longer and more soundly — so you can too. Measuring 52" x 28" x 5.5" and GREENGUARD Gold Certified for low chemical emissions, the Newton Crib Mattress exceeds the highest safety standards in the industry. The Wovenaire® core is proudly made in the USA. From newborn through toddler, this is the one mattress your child will need — and the one investment you'll never second-guess.
