An exersaucer is a type of baby activity center designed to support infants as they learn to sit up and explore their surroundings. It typically features a sturdy base with a seat that allows babies to bounce and rotate while engaging with various toys and activities attached to the surrounding frame. This encourages physical development and sensory exploration. Exersaucers are often used as a safe play area for babies aged around 4 to 12 months. They can help strengthen leg muscles and improve coordination, making them a popular choice for parents looking to promote their child's motor skills while providing entertainment.
