The Airlux mattress from Baby Dan has a super foam core with top foam memory foam for optimal comfort when the baby is sleeping. Memory foam is among other things help ensure a good night\'s sleep as the mattress absorbs body weight, avoiding pressure points. This reduces the need to turn and turn during the night. Memory foam allows the mattress to shape precisely after body shape and position so that the neck, back, shoulders and legs get the support they need. The entire body is supported in the correct anatomical position so that the spine rests in the best natural sleeping position. Because many children are warm when sleeping the mattress is also equipped with ventilation holes and air ducts that direct the heat away.
