The Organic Breathable Mini Crib Mattress combines breathability and waterproofing for a safer, healthier and more hygienic crib mattress design. The mattress starts with a firm, flat waterproof surface made from non-GMO sugarcane that is so pure, it actually meets food contact standards and easily wipes clean. This approach protects the inside of the mattress from urine, spit-up, and other messes. We then add a 3-dimensional cover with a soft organic cotton surface for increased airflow. This unique cover creates a breathable space under the baby which improves temperature regulation and allows the baby to breathe directly through the cover if necessary. The cover also features a waterproof backing which eliminates the need for an additional waterproof pad. Features organic cotton fabric & filling throughout and passes all federal and state flammability standards without any fire retardant chemicals or flame barriers whatsoever. Get all the safety features you need, including breathability, while maintaining a healthier, more hygienic, organic mini crib mattress design. Fits standard size mini cribs - approximately 23.5" x 37.5" x 3x. Made in the USA.
