Made with generous layers of organic cotton over a lightweight core, this waterproof mattress is both supportive and comfortable for your growing child. The 2-in-1 organic mattress features a firm side for babies and a medium-firm side for toddlers, all bordered in seamless, waterproof edges. The breathable organic cotton cover offers another waterproof layer and removes easily for quick cleanup in the washing machine. Lightweight so it's easy to move and maneuver, the mattress wipes clean with a damp cloth. 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.
