Made with generous layers of organic cotton over a premium innerspring, this mattress is both supportive and comfortable for your growing child. Designed for children that are still potty training, the 2-in-1 organic mattress features an innovative design that is waterproofed on one side, and quilted on the other. Naturepedic replaces flame retardant barriers, adhesives, and other toxic chemicals with healthier organic materials so you can be sure your child is rested with safe healthy sleep.
