    • Very handsome and safe seat!
Color: High Street
Such a nice seat! My 5 year old grandson loved it and it feels so safe and secure. It looks great in my brand new car.

    • Comfortable
Color: Dunes Edge
Very comfortable adjust the straps to child's weight and size before placing in vehicle. It was a little hard to place the seat belt behind the seat to secure it. If you have small hands it may not be a challenge. Overall I like it and the kiddo like it. I like that all the plastic pieces are covered with plush as I live in AZ and those areas of the seat can get pretty hot ... show more

    • Good value for the features, even if not the easiest to use
Color: High Street
Best value I could find for a convertible high back booster seat with built in harness option. Packs all the basic features at a reasonable price. Biggest complaint would be the buckles, which are all the cheap kind you find on budget Cosco car seats. First, the harness buttons are very tough for little fingers to press. Some may see this as a plus. For me, it's a negative. My 6yo had mastered the art of letting herself out of her previous car seat. Now she is once again reliant on a grown up to help her out – sad for her developing independence. Second, the LATCH clips are basic hook style connectors rather than seatbelt style push-button-release clips. These are a royal pain to unhook once installed. But maybe not a huge deal if you don't plan on moving the car seat very often. ... show more

    • Safe and comfortable
Color: Dunes Edge
Easy to install. Compared to other options, this brand seems to have better padding in the head rest/safety area. It was a hit with our rider.
