4Great Narrow Seat 

I would give this seat 5 stars, but I very much disliked the assembly of the seat. It wasn't that it was difficult, I just haven't had to assemble a car seat before, so it was off putting. It also made me worry a bit more about safety and such since there was a margin of human error in assembly.

These seats are narrow, which is why I bought 2. I have a Dodge Caravan and needed to fit 2 high back booster seats and 3 car seats in the 5 available back seats. These booster seats are narrow enough to fit both on the back row with a Diono RadianR100 Convertible Car Seat, Stone forward facing or rear-facing. (Leaving the two captain's chairs free for 2 other car seats.) It is a little bit tight in the buckling the boosters in with three across the back, but it can easily be done by an adult. (I'm looking into seat belt extenders now to make it so the kids can buckle themselves.

The seats are narrow, but easily fit my two children needing booster seats. (One is 7 years old, 48" tall and almost 50 lbs. The other is 5 years old, 42" tall and 42 lbs.)

2Hard seat. Not for primary car 

I bought this based on reviews but did anyone really ask their kid if they like it? My kid sat in it and said the seat was too hard. Which it is. Essentially it's hard plastic covered with fabric. I can't imagine having my kid sit in this chair for longer than 30 minutes at a time much less for long road trips. I gave this seat to his grandmother to use when she picks him from school and takes him home.

5Very nice booster 

My daughter loves this big girl seat! The pattern is really cute. I chose this seat because it rated well with Consumer Reports.
