The Star Kids Snack & Play Travel Tray is made of nylon and is easy to clean. It is also waterproof, so spills do not soak straight through onto your child. The tray includes two mesh pockets, one of which is designed to safely hold a standard drink bottle. The reinforced sides help to keep snacks, games, and crayons on the tray and stop them from rolling off onto the floor. The tray is easy to use and simply sits across the car seat, and the strap passes around the back of your child and is secured with a click lock. The strong and durable tray can be used with most car seats, booster seats, and strollers.
