We did a lot of comparison shopping and decided the extra cost for the features (like latch) certainly where worth the cost. This seat is great! When compared to other boosters, this feels well built and not flimsy like a lot of the 60-80 dollar models. My daughter loves it and it is very comfortable to her. When it comes time to outfit our other car, I will certainly be buying more of these!

my 3 1/2 yr old son was getting too broad for his britax. I found this one and he loves it :) I was wondering when I purchased it whether or not he would be able to nap in it as he often does when we go for a ride. He sleeps in this one more than he did his britax! It is not that much lighter than the britax but I find that it is easier to move from one car to the other.

We have two of these boosters. I love the fact that they have LATCH and can be secured to the vehicle seat. They are adjustable by shoulder width and height. Perfect for my tall children.

I LOVE this booster seat!
This booster seat is FABULOUS. The “latch” system is a great idea and the straps located just underneath the seat adjust to make the fit in your vehicle snug as can be, so the seat does not wobble around in your car. Also, it is easily transported to a different vehicle; the booster seat latched and unlatched easily. My 5-year-old is extremely comfy and cozy in it… so comfy and cozy in it that she fell asleep on a late night car ride — love the side wings and the padded seat…. Most important, the booster is SAFE! And, my daughter is tickled with her “own” cup holder!
Admittedly, there is a downside: my daughter can’t hook the seatbelt herself, something she could do in her previous carseat. Nevertheless, the many pros far outweigh this one “con.”
