DockATot Deluxe+ white bed-in-bed, made of cotton to comfortably support your baby. Used for about six months, until the baby started rolling over. The baby slept well when placed in this. When in use, a gauze blanket was always placed underneath the baby. However, there are some yellowed areas, so please refrain from purchasing if you are concerned about this (photos 3 and 4). Home cleaned. - Brand: DockATot - Model Name: Deluxe+ - Color: White - Material: Cotton Thank you for looking.
