The original 3D protector always allows your child to breathe safely, regulates heat and absorbs moisture. Furthermore, the Protector also keeps the mattress in the best condition. The SafeSleep 3D Protector offers versatile protection, impeccable hygiene and many advantages because your child sleeps on a layer of air. AeroSleep® 3D technology consists of 3 layers and has been extensively scientifically tested. Each layer has an important function so that your child sleeps well and safely. The 3D structure of AeroSleep® guarantees free breathing. The additional air layer also ensures the removal of excess heat and safe heat regulation. Furthermore, it is the moisture through the 3D structure discharged and absorbed into the absorbent layer. In addition to good breathing and a safe temperature, your child is therefore always dry. This prevents premature awakening and skin irritation. In addition to providing ample protection for your child, the Protector has another important function.
