Cots are small beds designed primarily for infants and young children. They typically have raised sides to prevent the child from falling out and are often adjustable in height to accommodate a growing child. Cots can be made from various materials, including wood and metal, and may come with features like wheels for easy mobility. In many countries, cots are a standard piece of furniture in nurseries and are often used until a child is ready to transition to a larger bed. Safety standards for cots, such as those set by organizations like ASTM International, ensure that they are secure and suitable for young children.
