I had the original version of this seat and loved it. When I had a wreck I replaced it with this seat as well as my other child’s E2F. They changed something about them and the cup holders won’t stay on. They lock in but then my kids barely bump them and they are off. Sometimes just the cup being sat in them knocks them off. Otherwise i like them

Too wide fir Kia telluride.
Beware if you have a Kia telluride!!! Impossible to buckle the seatbelt independently when you transition to a Highback booster with how deep Kia's seatbelts are and how wide this seat is. Otherwise we love it. Just bummed it won't work for the telluride.

I had a Diono Rainier for my daughter that we used for four years. I liked it a lot (as I prefer the Diono brand). However, the seat did not fit well in the new vehicle we bought a few months ago. I needed a seat that would fit in the space better and not slide around as much. I have had Graco products in the past but never loved them. However, this seat is great! I love the size of it (it doesn’t take up as much front to back space in the seat) and the no-rethread harness is so convenient. I like that the frame is steel-reinforced (one of the pros of Diono seats) but it’s not heavy or cumbersome to move or install. It was very quick to install with the seatbelt. We are currently using it as a five-point harness but I think it will work well as a booster when she gets to that point. I don’t feel like it’s super padded but my daughter was very comfortable in it on our recent road trip from Texas to South Dakota. If you are looking for a combination seat, this should be on your list.

My little one is sitting very comfortably in this seat. The ease of them able to do their own seat belt as they are in the “I do it” stage gaining their independence. Our child is also tall and the seat belt length is great for their area vs our previous car seat which was too tight and not enough slack

Cup holders need to be revisited
It’s great other than the cup holders. And I realize 2 stars over cup holders sounds extreme but they pop off SO easily and are required for safe use of the car seat. It’s a really poor design choice to make something so poorly designed a part of the safety system in any way.

Recline is a plus
I love the recline feature, for me was a requirement due to head flop. Not too much padding but I rather prefer safe over padding on the seat. Recommended

Grest booster
This booster is very comfortable and well made. It’s easy to install and take out. And the materials feel like an upgraded version of the other Graco boosters.

Over priced annoyance.
I CANNOT stand this car seat! The cup holders CONSTANTLY fall off, it is very cheaply made for that high dollar price they want for it. The only thing I like about it is the color/fabric design and the 5 point harness as some little despite being 40 +lbs are shorter or just little and I don’t think mine was ready for just full booster and seatbelt. It has no LATCH system (I personally like) so it’s just a free range seat in the back sliding everywhere ending up on the floor. There is little to no padding for comfort so I have no clue how my child sat in that thing on a 10 hr road trip! Some like this and this brand but I can’t wrap my head around why?! I do wish I would have just stuck with the NUNA brand.

3-in-1 car seat
Love this car seat! From the padded seat to the best side head protection I’ve ever seen in a car seat, this car seat is very well-built. It also can be turned into a booster seat as your child grows.

Great except cupholders.
Overall like the seat except the cup holders do my stay put. Constantly falling off after being clipped in. Makes road trips a tad more frustrating when he doesn’t have a place to set his drink and snack cup. Seems to be a common problem based on reviews
