Diono

Diono (pronounced DEE-oh-no) is a seller of strollers and car seats, based in Seatle, Washington.

The company was founded in 2000 as the seller of a car seat belt tightener (the "Mighty-Tite") and then expanded into various accessories for both car seats and strollers. In 2005, Sunshine Kids expanded into car seats, selling the first folding booster car seat (the Radian).

After a legal dispute with the non-profit charity organization of the same name, Sunshine Kids changed its name to Diono in 2011. In the mid 2010's, Diono expanded into strollers with several modular-type models.

As of this writing, Diono has paired back the stroller line to two current models: Excurze and Flexa (although older discontinued models like the Quantum are still sold online).
