The Diono Radian 3RXT SafePlus convertible car seat and Diono Ultra Mat and Heat Sun Shield car seat protector make an ideal bundle for safe and comfortable travel with children. The Radian 3RXT SafePlus is an innovative 4-in-1 car seat accommodating children from 4 to 120 pounds, with enhanced safety features like a steel anti-rebound bar that reduces rotation by up to 50% in rear-facing mode. Its slim design allows three car seats to fit across most midsize vehicles. The seat has six layers of side impact protection and an adjustable 12-position headrest. The Ultra Mat and Heat Sun Shield is a full-coverage seat protector made of durable, water-resistant material that shields back seat upholstery from spills, scuffs and indentations. Its non-slip top and bottom grip surfaces keep it securely in place. The protector has a storage pocket and added sun shield to prevent hot car seat surfaces from burning children. With rigorous crash testing and compatibility with all car seat types and installation methods, this bundle offers a complete solution for safe and comfortable travel with kids.
