Cot beds are versatile pieces of furniture that serve multiple purposes for infants and toddlers. They can be used as a standard cot for newborns, with adjustable mattress heights for safety. As the child grows, the cot can be converted into a toddler bed by removing one or both side rails. Some cot beds can even transform further into a small daybed or sofa for continued use as the child gets older. This adaptability makes cot beds a practical and long-lasting investment for parents.
