With over 20 years of design and engineering in the USA, we’re proud to be Made of Seattle, a city like no other. 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.

Our passion for problem-solving and safe family travel would come to inspire the creation of groundbreaking industry firsts; Radian®, the original All-in-One convertible car seat with a full steel core and the original expandable booster seat, Monterey®.

Now on any given day over a million children travel in a Diono car seat.

Our love for technical product innovation and world-class engineering has seen us go from strength to strength, with an ever-evolving range of All-in-One convertible car seats, booster seats, strollers, baby carriers and accessories. So, whether you ride with us, stroll with us, carry with us - with Diono you’ll unlock the #JoyOfTheJourney.
