Diono is the only car seat brand that offers convertible+booster seats with a full steel frame making them one of the safest car seats available today. The New Diono Rainier is the ultimate in car seat safety with new deeper side walls providing enhanced side impact protection taking Diono car seats to a whole new level. With its extended rear-facing capabilities, it can comfortably seat rear-facing children from 5 to 50 lbs and forward-facing children from 20-90 lbs in 5-point harness mode. Additionally it converts to a booster for children between 50 - 120 lbs or up to 57" in height.

The aluminum reinforced headrest has 12 height positions for adjustable head support and additional EPS foam surrounds the child’s head and body for complete side impact protection. Its unique SuperLATCH™ system makes installation easy and the Rainier is NCAP crash tested, the industry benchmark for verifying child seat performance in severe accident conditions.
