Designed and engineered in the USA, we’re Made of Seattle, a city like no other. We believe in having it all, from the fast-paced digital-led metropolis to the surrounding mountainous landscape of adventure. Seattle’s unique cultural identity and pioneering spirit inspired the Diono difference way back in 1999, and it’s what continues to drive our innovation today.

Diono’s commitment to child safety is not just driven by industry standards but by the need to always go above and beyond to deliver products that serve and protect.
