Diono Monterey XT High Back Belt Positioning Booster Car Seat - Teal

This item is discontinued.
Description
The Monterey XT is a full-featured, expandable high-back booster seat designed to fit growing children 40 lb to 120 lb. The adjustable head rest and deep, aluminum reinforced sides are lined with energy absorbing EPS foam for side impact protection. The shaped and contoured seat ensures the correct seating position and makes for a comfortable ride. A simple-to-use dial on the back adjusts the width of the seat to fit a child’s shoulders up to 20" wide. The 11-position headrest gives ultimate flexibility and adjusts up to 6.5" in height with one hand for an easy, precise fit. As a fixed-position booster, integrated LATCH connectors and front adjusters allow for a safe and secure installation in seconds (LATCH use is optional) and keeps the seat in position when not in use. Plus with wipeable fabrics and a removable, washable cover, the Monterey XT High Back Booster is easy to look after and keep clean. Also features 2 extra-deep cup holders and snack trays which fold away when not in use. Monterey XT can also be used as a backless booster and packs flat for travel and storage.

I bought this for my son who is 4’2” and about 50lbs. He loves it! He said it’s really comfortable and the seat base is bigger than most. It fits well in our Jeep Cherokee and I would have to say this is the best booster seat I have ever bought.

Love this seat!!

From the slick color and design to the extra functions that a regular Highback Booster seat lacks.
This seat is amazing in every way possible.
You can latch it to your seat so when the kiddo is not in it there is no need to worry about it flopping around.
Then the head rest can go pretty high to accomodate older and taller kids while the sides expand as well.

This is the PERFECT seat if you intent to have your child in a highback booster for as long as possible.
My 7 year old is bigger for his age, about 4'8 and 70 lbs and this seat is perfect for him and there is still so much more room for him to grow!!
Pros
  • Latch
  • Headrest height.
  • Side expander.
  • Color and material.
Best Uses
  • For a child you want to be in a Booster seat for as long as possible.
Cons
  • None in my size.

Fantastic got taller kids
November 25, 2019
This seat is perfect for my tall and stocky son. I searched for a while to find a seat that was both wide and tall to keep my son in a full booster longer. The Monterey met every check. My son thinks this seat is comfortable and likes sitting in it. Installation is easy with the latch system.
Pros
  • Extended height and weight limits
  • Sturdy
  • Easy install
  • Quality materials
  • Safety requirements surpass minimum
  • Stylish look
  • Comfortable
Best Uses
  • Great for any eligible child but perfect for those children that are taller or heavier than average.

Very solid booster does take up more room than expected because of the top.

I bought his seat for my almost seven year old. I was pleasantly surprised how sturdy it was and he says it’s quite comfortable. It was easy to install, a little different from other seats I’ve had, but didn’t take long to figure out. I like it and my son does too!

I really was excited to try this booster out for my son I loved how it was not heavy at all nice head support the frist thing i look for in boosters nice comfy feeling nice color but..What I didn't really like is that the belt gets so tangle when its time to buckle up and off didn't feel like returning and going thru the process and happening again so I kept it .

Sturdy Seat at a Great Price

After having a pretty flimsy Chicco booster, I sprung for the Diono and could not be happier. A steel frame but not too heavy. My son reports he is very comfortable and I feel good about well he is protected.

This is definitely not a travel seat. It’s big and heavy. And very safe. We have three Dionos already so I knew what to expect. And I got it. I love and trust it enough that I just ordered a second one.

Easy Purchase - Great Booster
April 22, 2017
This booster seat was SOO easy to install in comparison to the Diono Radian RXTs that I have for all my little ones. I wish the car seats could be installed this easily. It comfortable and looks nice and my daughter loves it. Ordering from Albee Baby was easy and clear. No hidden fees at the end. What you see is what you get. I'm very happy with my purchase!

I love how sturdy and comfortable this seat is. I bought three in different colors for my three oldest children (ages 6, 7, and 8) and they're all very happy in them. There's great support for them and the fit is excellent, I love how adjustable they are. I own a few different booster seats in this price range from other brands that I use in our other vehicles but these are definitely my favorite. You are required to have vehicle head support behind the seats, even with the high back portion of the seat attached, so they may not work for all vehicles but I highly recommend them if they do.

Are you able to fit 3 of these in 1 row of a van or suv?
Cambria and Monterey booster seats are designed to accommodate growing children and have a wider seat base, therefore they cannot fit three across in most vehicles.
