The Infantino Music & Lights 3-in-1 Discovery Seat & Booster is an interactive seated positioner, snack-time booster, and table seat all in one. This all-encompassing seat and booster with a 3-point safety harness provides early sitters a secure place to sit while keeping them happily engaged with 6 fun activities, including a light-up piano with 20 songs & sounds. Engaging play pods encourage sensory development and help build fine motor skills, and are removable for floor play or on-the-go fun. When your little one is ready for a snack, slide the toy pods apart to reveal a mealtime tray with a cup holder. Securing straps allow the booster seat to attach to most kitchen chairs, and the soft foam seat is comfortable for babies and easy to clean after mealtime. The Infantino Music & Lights 3-in-1 Discovery Seat & booster is perfect for babies and toddlers ages four months to three years (up to 33 lbs).
