GOUUN’s foldable play gym and playpen set grows with a child, transitioning from a cozy activity mat for newborns to a spacious enclosure for toddlers up to age three. Five removable sensory toys, including a self-discovery mirror and sound-making heart, clip onto the arches to keep little ones engaged during tummy time. The sturdy playpen features soft foam-padded joints and breathable mesh walls that offer a clear view of the action inside.
