Diono Monterey 5iST FixSafe High Back Booster Car Seat

Introducing the next generation of expandable booster: The Monterey 5iST FixSafe. Designed for ultimate portability, this innovative booster transforms in seconds from a compact fold to a full-size seat, without compromising safety or comfort.

At 25% smaller than the average booster, the Monterey 5iST FixSafe folds down into a compact and convenient size, featuring an integrated carry handle and carry straps with a designated storage compartment. Whether you're on the daily commute, carpooling, storing in the garage, or jumping in a cab, you can always take safety with you for the joy of the journey.

Suitable for children from 40 to 120 lbs, the Monterey 5iST FixSafe expands in height and width to provide up to 85% more room as they grow up to 63 inches tall. With 12 headrest positions and an expansion up to 20 inches in width, this booster can adapt quickly to growing children, offering plenty of room for their shoulders, hips, and legs.

These great features have been combined with SafePlus engineering, ensuring the Monterey 5iST FixSafe has been subjected to a combination of the most rigorous crash tests – front, rear, side impacts, and rollover – to deliver the safest seat possible. The advanced SafePlus side impact protection features 8 layers of interlocking EPS and EPP foam, including the SafePlus energy-absorbing shell, to shield and protect with SafePlus airflow technology built-in for optimum child comfort.

The open design of the Monterey 5iST FixSafe features easy-to-use SafePlus secure belt guides to eliminate misuse and a SafePlus secure belt lock to ensure the adult seatbelt is always routed correctly. The seat base is contoured for child comfort and includes a cup holder for road trip drinks and snacks.

Designed with a simple 4-step installation and adjustable rigid latch FixSafe connectors, the Monterey 5iST FixSafe can be used straight out of the box, with no assembly required. The FixSafe connectors offer a simple way to secure the booster to the vehicle latch system, for a safe and convenient installation every time.

One-hand easy-adjust SafePlus 12-position headrest and backrest that grows up with your child. Engineered for safety and comfort with 8 layers of Side Impact Protection, the Monterey 5iST FixSafe's backrest has deep padded cushioning for comfort and support, with contoured premium soft fabrics that can be easily removed for machine washing.

The built-in removable cup holder keeps your big kid's drink close at hand, while the SafePlus belt guides provide easy access to the seatbelt buckle, helping your child with self-buckling (don't forget to check, though!).

Unbox, unfold, install, adjust, and go – all in 2 minutes or less, thanks to the SafePlus rigid LATCH connectors and the quick-release latch button, making it easy to move between cars or store at home.

Engineered with the most side impact protection, the Monterey 5iST FixSafe's rigid shell is reinforced with 8 layers of high-impact aluminum and EPS energy-absorbing foam, to protect the head, shoulders, and torso.

Folding to the size of a carry-on bag, this booster is great for storage in the trunk or at home, and perfect for trips by plane when you need a boost for your big kid.
