The HUANGER Foldable Musical Piano Baby Play Gym features soft, easy-to-clean fabric made from safe, eco-friendly ABS food-grade materials to ensure your baby's health. Designed for babies over 18 months, it offers a multifunctional piano fitness frame that encourages muscle development. From three months, babies can press piano keys and touch pendants to strengthen arm and leg muscles. At six months, sitting and playing helps improve hand-eye coordination. The bell ring hanger enhances grip flexibility and supports teething with a safe gel-covered ring. Musical sounds from the piano keys also stimulate your baby’s hearing development.
