The Diono Rainier all-in-one convertible car seat takes child safety to a whole new level. Engineered with a full steel frame, the Rainier offers maximum safety and protection for your child for up to ten years. The robust aluminum reinforced 12-position head support and extra-deep sidewalls offer optimum side impact protection, while the luxurious infant support cushions provide additional comfort and security for the smallest of passengers. The seat is NCAP crash tested, the industry benchmark for verifying child seat performance in severe accident conditions. Designed to grow with your child, the Rainier comfortably seats rear-facing children from 5-50 lbs., while offering one of the highest forward-facing capacities of any car seat in a 5-point harness - from 20-90 lbs. (up to 57" in height). Converts to booster mode for children between 50-120 pounds (up to 57" in height). The space-saving design allows extra room for passengers, while providing spacious interior for your child. Diono's unique SuperLATCH system makes installation quick and simple. The seat folds flat for easy transport and is FAA certified for airplane travel. With a 10-year lifespan, the Diono Rainier is the perfect choice to keep your child safe and snug, wherever the journey takes you.
