    • Lightweight, Safe, and Kid Approved
Color: Sea Serpent
This booster seat feels safe and secure without being heavy. It’s lightweight but still sturdy, looks good in the car, and does what it’s supposed to do. I wouldn’t call it luxury, but it feels dependable. It’s easy to move between cars, which is huge for us—lugging around our other booster was too much. I also like that when you extend the height, it widens slightly—it just makes sense. Approved by my kid: “It’s very comfy and makes me feel like a big boy.” ... show more

    • Perfect for Grandma Mobile
Color: Sea Serpent
Comfy (according to the littles) and not as cumbersome as the seats I had previously. As grandma on fun-duty, I don't need the seats everyday, and it's easy enough to tuck them in the back of the car when not in use.

    • Its great
Color: Black Sand
It's perfect for my four year old. She absolutely loves it. It works great for all of her needs. The only two problems I have is that it's hard for my four year old to buckle herself in, the second problem I have is that I have to wiggle the car seat so that I can buckle her in the car seat. Now that doesn't mean that she is any less secure in it, though. She is still very secure. I feel very good about driving with her in the car seat. To keep in mind, I do have a sports car. So maybe that could be the problem for the second one. Overall, it is a very wonderful car seat for a child going into a booster seat. ... show more

    • Easy to use
Color: Beach Wave
Easy to use but they do not have a way to strap them down in the car. The only thing holding the seat in its place is your childs weight and the seat belt of the child.

This booster seat is exceptional! Its solid construction allows for use with or without the backrest, providing versatility for your child's needs. The convenient cup holders add to its practicality. Not only is the seat comfortable, but it also fits seamlessly in both of my vehicles. What's more, it's designed so that my granddaughter can easily latch it herself most of the time.
