How big is the Diono Monterey Booster?





Can I see the manual and install instructions for the Diono Monterey Booster?

There is no installation required. You may place the booster seat directly on the vehicle seat if there are no LATCH anchors. If there are LATCH anchors, the LATCH system on the booster can be used, but it is not required.

What are the differences between the Monterey and the Cambria Booster Seats

The Monterey XT comes with an 11 position headrest, expandable seat back, aluminum alloy reinforced sides lined with EPS foam for side impact protection, and a stronger seat back designed for added strength.

The Cambria comes with a 6 position headrest and is lined with EPE foam for side impact protection. Both easily convert to a backless booster.

Come and view both with our child restraint techs in store at Baby Box, 18 Ihakara Street Paraparaumu.

Is there a top tether on the Diono Monterey?

No there is no top tether.

If you are after a Booster with a tether we suggest the Maxi-Cosi Titan.

What other parents have to say

"I own the monterey XT booster by diono in heather grey. I love that it is lightweight if we need to switch it between my husband and my vehicles. It is a great investment because it’ll carry you through as your child grows. The headrest easily moves up and down and the side panels can be expanded by quick and easy rotation on the back. We really like this booster seat and trust that it will keep our child comfortable and most of all safe."
