Durable and packable
Long time Diono fans and these did not disappoint! 2 of these can fold down and fit into 1 car seat carrier with room to spare! They aren’t insanely heavy but also feel very durable. I have taller kids and they fit them wonderfully. As you raise the headrest the sides fan out. It’s impossible to have 3 seats across. We have a Jeep Grand Cherokee and the middle seat does become nonexistent but we were able to get one of these and 2 Diono 3QXT in that car.

Finally found a high back booster that works!!!
Color: Purple Plum
After ordering two other high back boosters and both of them not working in our Ford Expedition, this one works. Our school pickup line moves fast so 6yr old has to jump in and get strapped in herself. Our seat belt plugs are deep in the seats. She has to bend over quite a bit to reach them as she’s small. The seat must be narrow which this one is. Also requires a latch system so the seat doesn’t move around and cover the plug. She has to pull the seatbelt out all the way and other car seat seatbelt guides at the shoulder would cause the seatbelt to lock up. Anyways she can operate this one by herself 99% of the time and we’re happy with the quality.
