I recommend this product
Color: Pink Cotton Candy
I am extremely satisfied with this car seat that I bought for my 6-year-old daughter. It fits perfectly in my 2020 Chevy Equinox and provides ample space to accommodate a third car seat for my baby arriving in August 2026. The installation process was straightforward; it can easily be secured to the base of my car or installed with the seat belt alone. It is adjustable and delivers excellent value for money.

Great Booster Seat
Color: Pink Cotton Candy
Daughter loves it. Simple to install. Comfortable, easy to use. Already have had Diono car seat for a couple of years and this appears to be of the same solid quality. Recommend.

Impressive fitting in a third row of a Lincoln Navigator! Impressive fitting in a third row of a Lincoln Navigator!
Color: Blue Surge
I bought 3, blue, purple and teal, colors are beautiful, the seats looks good and fitted perfectly in both of our cars, a Subaru Forester 2015, 3 in the back seat, it’s tricky to put the belt but we manage to pass it between the handles of the seats and then buckle them, to help with the buckle i added a rubber to help stay on top, and since the latches are built that way, we managed to latch the middle one to the sides latches a little bit looser so it doesn’t bother with the buckles. The cup holders are great, they fit 16oz cups, and does help to get the seats aligned. Also i put them on our second car, wich is a Lincoln Navigator 2022 and they fit perfectly in the third row seats, the 3! And have some more space too. I am very happy with our purchase and enjoying it! We had in that car 3 cybex solution s but they never fitted 3 in the third row, with this change, we have jut won an extra seat in the car. Very impressive. Would recommend it! :) The first 2 pictures are from the Subaru Forester, and the video and the last 2 pictures are from the third row in a Lincoln Navigator

It fits!
Color: Black Storm
Fits 3 across mixed with 2 Diono Radian 3R car seats in a 5th gen 4Runner. Well thought out as expected and is well built. I’ll be getting 2 more as the other littles grow!

Pretty in Pink
Color: Pink Cotton Candy
My daughter loves this seat! It’s very comfy, small profile but roomy for her. She is 4 and right at 65 lbs., absolutely love the latch system so the seat doesn’t slide around constantly. We have a Kia Telluride with captains chairs, it fits very well, the seatbelt buckles in the chairs are set very deep so buckling is a little bit harder but it’s not the fault of the booster seat. We placed a rubber buckle holder on it and it does help. We would hands down purchase this seat again…our daughter loves the color and the cupholders/snack tray

Depends upon the car
Color: Blue Razz Ice
Everything was good it fit in our expidition we like the color and comfort and how sturdy and safe it feels with the latch system the price was good for us but the ease depends upon the car like I said I and the same two backless work in our bigger suv but in our small Nissan Altima I can’t get the three across that it said was possible and my two backless boosters are Diono connect3 as well
