Smaller space, same Newton safety — the Newton Mini Crib Mattress brings the brand's industry-leading breathe-thru technology to mini cribs without any compromise on what matters most. Designed exclusively for rigid-sided stationary, mini cribs and measuring 37.75" x 23.75" x 3", it fits most mini crib frames and has been tested to fit with several popular models including the Newton Galileo Mini Crib, Babyletto Origami, Babyletto Gelato, DaVinci Dylan and Carter's by DaVinci Colby. The patented Wovenaire® Core allows air to flow freely in every direction, preventing overheating in even the most compact sleep spaces and reducing the risk of suffocation according to independent lab test results. Independent testing confirms babies sleep longer and more comfortably on Newton, thanks to optimal airflow, firm support and a surface free from the dust, allergens and irritants that build up in conventional mattresses. Fully washable and GREENGUARD Gold Certified, the Newton Mini is the thoughtful choice for families who want the very best for their baby — regardless of the size of the crib.
