The Diono Monterey 5 i-Size iST FixSafe is a super comfy booster seat with innovative side protection and a compact folding system. Suitable for children from 100 - 150 cm tall (approx. 4 - 12 years old). Includes cup holder and carry straps.

The Monterey 5 i-Size is the first booster car seat from Diono with i-Size approval for transporting a child in the 100-150 cm height range (from approx. 4 to 12 years old). The i-Size iST FixSafe offers a roomy seat with Safe+® side impact protection inc. Side Impact Management Pod to provide safety traveling. Its adjustable headrest finished with premium quality upholstery and breathable side panels ensure excellent comfort for your growing child. The chest strap guides ensure optimal positioning of the 3-point car belt on the child's body when the headrest is elevated. The profiling of the backrest and the seat makes the lap belt runs correctly on the toddler's thighs. In addition, the seat has been equipped with FixSafe ISOFIX anchoring system, which ensures easy installation in the car.

The Diono Monterey 5 features a Fold N' Grow folding system, which is a novelty in this car seat model. The seat can be easily folded into a cuboid-like form. The result is that it takes up less space when you need to store it at home or it in the trunk of a car. The braces on the back of the backrest allow you to move the folded car seat as if you were carrying a backpack. What's more, its dimensions after folding are small enough that the car seat can be taken on board the aircraft and placed it the hand luggage compartment. This car seat is just perfect for travelling and comes with a practical cup holder, which can be mounted on one of the two sides of the seat.
