The Mamas & Papas crib in white colour will be a unique first crib for the first years of your baby. The base of the mattress has 3 height positions to adjust according to your needs. The high position is for when the baby is a newborn and the low position is for when he has grown up. When your baby grows up it can be converted into a toddler bed to last up to 4 years. A very beautiful choice for the nursery room!
