Great car seat for 5 years old!

I am impressed with this carseat from Cosco. It fits perfectly for my daughter, and she really likes it. I think it is more comfortable than the others same brand. I would feel safer if it had the shoulder straps. However, it does the job. It was in a perfect shape when I received it and arrived on time.

Easy to Install and Grows With Your Child

I installed this booster seat today, and the setup was easy enough to do on my own. The instructions were straightforward, and it fit nicely in the car. I do wish the seat cushion were a little thicker for added comfort, but my toddler seems to like it and had no complaints. The Sonic Diamonds design also looks cute. One feature I really like is that it grows with your child. When she's older, GSL, I can remove the back and continue using it as a backless booster, which makes it feel like an even better value. So far, it seems like a practical and convenient booster seat. As long as my toddler is comfortable and secure, I'm happy with it.

Works great for picking my grandson up from school. Easy to assemble, and I love that it can be moved from car, to car, without all of the problems with a regular car seat.
