Welcome a world of flexibility with Monterey® 2XT. Suitable from 40 - 120 lb (18 - 54 kg) approx. 4 - 12 years. We all know that children grow at different rates, and not one size fits all. As one of the most flexible car seats you’ll find, Monterey® 2XT is lightweight, super portable and with adjustable headrest and expandable sides, plus easily converts into a backless booster seat, ensuring a proper fit for your little one at every age. Featuring 11 headrest positions and 2 recline positions, Monterey® 2XT can adapt quickly to growing children, with plenty of room for shoulders, hips and legs. A simple-to-use dial on the back adjusts the width of the seat up to 20” wide, while the headrest adjusts up to 6.5” in height with one hand for an easy precise fit. Clever design thinking and award-winning safety features make the Diono difference. That’s why the Monterey® 2XT includes our superior side impact protection with aluminum reinforced head support and energy absorbing EPS foam, to accommodate growth spurts without sacrificing protection. Equipped with simple connectors and front adjusters, Monterey® 2XT can securely connect to your vehicle in seconds, enhancing safety and stability as well as allowing parents to switch between vehicles with ease. Lovingly engineered for every journey with two fold away cup holders to keep drinks or snacks upright and within reach, so both children and parents can sit back and relax.
