Do you need a mattress for the crib? 

 A baby mattress is a mattress for a child under one year of age. Because babies grow and develop very rapidly at this stage, it is the most vigorous stage of growth and development in human life, and the baby's body is relatively soft, if not paid attention to, it will easily lead to dysplasia. Therefore, the mattress used by infants should have a higher standard and be different from that used by adults. In developed countries such as Europe and the United States, the concept of baby mattress has been widely known, but in China, with the entry of Spanish Yikasi mattress brand, it has filled the gap of professional baby mattress. 

 "Sleeping on a hard bed and using a hard mattress" has always been regarded as a good habit for people to protect their backs and keep fit. But experts warn that the hardness of the bed varies from person to person. Especially for infants and young children in the period of growth and development, such as sleeping on hard mattresses, it will cause skeletal dysplasia, and even leave the hidden danger of "scoliosis". The ideal mattress for infants and teenagers should be composed of soft upper and lower layers and firm, firm and elastic middle layers. On the one hand, the middle layer can give the child's body the necessary support, and on the other hand, when it is subjected to the pressure generated by weight, it can be transmitted to the soft lower layer, thus supporting the child's body without spinal deformity.
