Activity gyms are play areas designed for infants and toddlers, featuring soft surfaces and various engaging toys. They often include hanging toys, mirrors, and textures that stimulate a child's senses and encourage exploration. These gyms promote physical development by encouraging reaching, grasping, and tummy time. Parents often use activity gyms to create a safe space for their children to play while they supervise. Many gyms are portable and can be easily set up in different locations, making them convenient for home or travel. They are a popular choice for parents looking to support their child's early development through play.
