Made from 100% cotton fabric. The raised edges of the mother's bed help the baby sleep safely. The part tied with a ribbon is the foot of the bed. It is sent in a PVC bag. Lay the baby down with the feet on the ribbon side. Wash by hand or in the washing machine with plenty of water at 30 degrees. Do not keep it wet and do not use bleach. Keep dark colors separate when washing. You can dry it in a tumble dryer at low speed.
