A playpen is a safe, enclosed space designed for young children to play in. It typically consists of a sturdy frame with mesh or solid sides, allowing parents to keep an eye on their child while they play. Playpens can be used indoors or outdoors and are often portable, making them convenient for travel. These products help prevent toddlers from wandering off or getting into dangerous situations while giving them a designated area to explore. Many playpens come with additional features, such as toys or activity centers, to keep children entertained. They are commonly used by parents and caregivers to ensure safety during playtime.
