Maximum protection, unmatched safety record.

Your child’s safety is at the heart of everything we do. That’s why we engineer our car seats to be the strongest and safest possible and to test them to the highest standards. After all, we’re parents too.

Diono car seats exceed federal crash standards and consistently achieve the highest ratings in the industry. Our car seats are side impact tested and NCAP tested. Diono is the only car seat maker to reveal our crash test results. Please visit our Safety Center to review crash test videos and test results.
