Diono Monterey® 5iST FixSafe™ reinvents the way you travel

Car Seats
Designed for ultimate portability, Monterey® 5iST FixSafe™ transforms in seconds from a compact fold to a full-size booster seat, without compromising safety or comfort.

2021 has already been a big year for us here at Diono but we’re not slowing down anytime soon. This month marks the launch of our all-new booster seat Monterey® 5iST FixSafe.

Famed for being the original expandable booster seat the Diono Monterey® is a firm family favourite, found in back seats across America. But just as travel has changed, so have we…

We are lucky at Diono to have a history of industry firsts thanks to our pioneering Seattle roots that drives innovation and diversity. As we build on this legacy, we are constantly looking at the world around us and how families travel. Family travel is changing and with it comes a whole new pace of life. Families demand more convenience and quality from products that adapt to their changing needs.

As a team we asked, how do we simplify travel, so families can take safety with them wherever they go?

We took the existing Monterey® design principles and set out to improve mobility, functionality, and intuitive use, from buying to unboxing and installation. Monterey® 5iST FixSafe™ can transform in seconds from a compact fold to a full-size booster seat and features an integrated carry handle and carry straps. So, on the daily commute, carpooling, storing away or jumping in a cab, with Monterey® 5 you can always take safety with you for the joy of the journey,says CEO, Tim Maule.

Smaller, compact, and more convenient often means a compromise along the way. Not with Diono. The Monterey® 5iST FixSafe™ has all the safety features you’ve come to expect from our award-winning products. Made with the Diono SafePlus™ engineering promise and subjected to a combination of the most rigorous crash testing including front, rear, side and rollover. Our focus on complete child passenger safety is represented in the all new SafePlus™ secure belt lock feature and belt guides to ensure the adult seatbelt is always routed correctly. The FixSafe™ Rigid LATCH connectors also offer a simple way to secure the booster seat to your vehicle latch system, for a safe and convenient installation every time.

Parents can still expect the awesome Monterey® features they know and love, with height and width expansion providing up to 85% more room to grow throughout the 8 years of use from 40 - 120 lb and up to 63” tall.

“It’s always hard to take a classic and redefine it, but we believe our vision for ultimate portability takes the Monterey® and makes it even more relevant for the next generation,” says CEO, Tim Maule.



The Monterey® 5iST FixSafe is a truly portable solution for the modern parent - welcome to travel reinvented.
