A portable crib, also known as a travel crib or play yard, is a lightweight and foldable sleeping space designed for infants and toddlers. It provides a safe and comfortable environment for babies to sleep or play while on the go. These cribs are typically made from durable materials and can be easily set up and taken down, making them ideal for travel or visits to friends and family. Many portable cribs come with additional features such as a mattress, storage pockets, and a canopy for added comfort. They are often designed to meet safety standards set by organizations like the Consumer Product Safety Commission (CPSC), ensuring that they are a reliable option for parents.
