We have been a family of frustrated people ever since our oldest transitioned to a highback booster because our car (Model 3) has absolutely atrocious design when it comes to accommodating car seats: the rear inboard seatbelt buckles are deeply flush/recessed and have no give. We were using a Graco Tranzitions as a high back booster before (a great seat in any other car and one of the narrower more affordable ones at that), it was still just barely too wide to buckle easily. The Monterey 5 iST is not only narrow, but it has ISOFIX. The cutaway allows for easy access to the buckle so my kid can do it himself without struggle. I am pretty sure some savvy engineers have lived through the hell of the Model 3 and designed this seat with it in mind. THANK YOU Read more

We chose this model for the compact fold/straps because we were planning plane travel with driving on the other end for our 5yo who is not mature enough for a bottom seat only booster for any significant distance.The fold is great and compact. The provided straps are just webbing, and There was no way we’d use them for more than a minute. I found some clip on backpack straps on Amazon that were more comfortable, but it sits at an awkward angle. You’re better off using some bungee cords to strap it to the handle of rolling luggage if you’re going very far.We gate checked it for our flights but you may be able to put it in an overhead bin.Since the back does not detach, it’s easy to quickly install and remove from an Uber. I had trouble getting the isofix latch connectors to work in one Uber (Toyota sienna, I believe) but it was a short ride so we went without them completely attached.We also like that the sides of this seat expand like the other Monterey models because my son is tall with a long and wide torso and would likely have cramped shoulders by the time he ages out of a standard booster seat. What I didn’t realize until we got it is that the width expands as you raise the headrest, not independently like the other models.Overall we like it but unless you’re planning some travel that includes Ubers and/or flights where you’ll rent a car or ride with family/friends on the other end, save your $$. We have the $100 XT model in our other car and it functions just as well if you’re installing it once and leaving it there (and it still has the expandable back panel). If your child is average height/weight/build, you can pick something even cheaper. Read more

This booster is not only nice to look at but it's comfortable. The seat doesn't have as much padding on the bootie as our old seat but he doesn't mind. The fixsafe latch system was a bit hard to get to pop out at first , I had to really push the button extremely hard to get them to come out. But then the install was a breeze. So easy. The chair itself is quite light which makes it convenient to put in other cars if necessary, it folds completely into itself and makes for very easy travel. It could easily fit in an overhead compartment on an airplane and it comes with straps to wear it on your back as a " back pack ". The cup holder is bigger to accommodate bigger cups and it's easy for my son to put the belt on himself. Overall I'm really happy w my choice. We are a diono family and when my old one was compromised from an accident it was a no brainer I was getting another Diono. We upgraded from a Rainier to the Monterey since my son is getting bigger and taller this seat accommodates up to 63 inches and 120 lbs. So he can be in it longer. Which was a big appealing factor in the decision. Read more

I purchased this seat thinking hard latch was a solid connection preventing the seat from leaning to the sides (the purpose of hard latch in the first place). This one moves more than the strapped seat. Good idea poor execution. Cheap looking and feel in person. Had to buy another one Nuna aace to get what was originally intended. Read more

I am absolutely THRILLED with my new Monterey 5iST! Diono’s products have protected my family for many years now (this is my 3rd purchase) and recommend them to all of my mommy friends! Thank you Diono for continuing to make the best baby gear on the market! Read more

The use of photo renderings to embellish a cheap looking product is a waste of time for all. I ended up buying the Peg Perego Viaggio Flex 120 licorice for safety, comfort, quality and style. Read more
