    • Fits Volvo XC60 and XC90, great for tall kids!
Color: Black Style: Monterey 2XT Pattern Name: Solid
I do wish the limits of the Diono seats with extra protection were as high as this one, but I’m glad they have something that goes to such high height limits, and this still has very good safety features beyond the requirements. Our son is very tall and I was glad to find a seat he could use for such a long time. We’ve had this over a year now—two of these actually, and the quality has been very good. My son also finds the seat very comfortable. We have two extremely hard to fit vehicles—Volvo 2012 XC60 and 2013 XC90, and this seat actually fits and works with the non-removable headrests and jut forward. These are a very good value for the money because of the high height and weight limits. Glad to have found these. ... show more

    • Perfect low profile children's booster seat.
Color: Black Style: Monterey 2XT Pattern Name: Solid
This was a great cost effective choice for us in our 2024 Nissan Pathfinder. We were looking for something with a smaller profile in the captains chairs so the 3rd row was still accessible. I did a lot of research to find something that was capable of fitting our needs and also being safe for our girls, and this seat definitely fit all of our needs. This was a recommended buy from consumer reports with recommended great performance. With the built in latch anchors in the front the installation is very easy. It allows the seat to feel secure and stable while using the cars seat belt. It has dual cup holders that fold away. The material is nice and soft and seems like cleaning will be very easy. Overall we would definitely recommend. ... show more

    • Great seat for bigger kids!
Color: Black Style: Monterey 2XT Pattern Name: Solid
Works great for my big 6 year old who outgrew another convertible high back booster seat. Super easy to put together and install, and my daughter loves it.

    • My Son Loves This Chair
We recently transitioned from the baby-seat to this one for my 4 year old son. He's tall, but light, and my wife was very insistent on following the weight guidance for transitioning him to a new seat. When we did transition, my son was so happy! He loves the little cup and snack holders. The seat itself seems very comfortable, and my sone thoroughly enjoys the increased movement that the chair offers. It is very easy to install, although I do have to say that the installation instructions themselves stink. It took longer to try to figure out how to install the chair than to actually install it, and now that we know the trick, it is very easy to install. It seems very secure, and has been through one minor fender-bender with good performance. Overall, I would recommend this chair as a safe and comfortable alternative for children growing out of baby seats. ... show more

    • Just latches, no top tether anchor.
Color: Black Style: Monterey 2XT Pattern Name: Solid
Review Image by Stephanie Stephanie
I have two kids (5 and 7) both with slight autism that are outgrowing their Graco convertible seats. With their seat’s expiration dates also closing in, I decided to go to make the leap of faith to regular seat belted boosters. I feel like I looked at every single one on Amazon before choosing these for their convertibility and price point. I was a little disappointed realizing that there’s no anchor with these, just the latches. I assumed anchoring was included in latch system, that’s on me. Obviously it’s because the seat transforms into backless, I guess I just thought the back would have that part. Oh well. The seatbelts ARE a little hard for kids to do themselves because of how wide the base is and how most buckles are designed to be flush with seats but hopefully the kids will get the hang of it. I will buy a seat belt buckle booster and see if that will aid the children in their independence. Side note! This may come off a little OCD but it bothered me. I ordered these two black seats at the same time, and they came with different accent colors… Literally changed the number in cart from 1 to 2. One seat has a GRAY Diono with a RED tag and one has a WHITE Diono with a GRAY tag. I included a picture but it may be hard to tell due to lighting. At first I thought they must have different manufacturers dates or be different models some how but nope they are exactly the same date and everything. I can’t even exchange one because who knows which one I‘d get back lol. Don’t judge me, pray for me lol. ... show more
