  • What comes in the box?

    Monterey® 2XT Booster, Instruction Manual, Cup Holder

  • Diono booster seats can be used for children weighing 40-120 lbs. and are 38-63 in. tall. Typically once a child reaches 5 years of age they are mature enough to ride in a booster seat.

  • Our booster seats fit 2 across in most cars. Each vehicle model is different and allows for various seating positions. Consumers should consult vehicle owners manual for appropriate car seat placement in their car that may fit more than 2 across.

  • The Monterey® 2XT Latch is recommended to be installed with the lower anchors if you vehicle is equipped with them. However, it can be used without.

  • Diono booster seats are not meant to be used on airplane. Boosters require a lap/shoulder belt and airplanes only have a lap belt.

  • Please consult the seat manual. Diono Cambria and Monterey seats manufactured prior to 2017 can be used with Ford's inflatable seat belts. Newer models will not allow them to be used and will be stated in the car seat's manual.

  • All Diono booster seats have a life span of 8 years, starting from the date you purchase your seat. In the event the date of purchase cannot be determined then we use the date of manufacture.
