Bought this for my 4-year-old who is on the smaller side (33lbs, 41in) and he loves it! It was relatively easy to install and doesn't move around at all in our Explorer. It was easy to adjust for his height and he says it is very comfortable. He also loves the two cup holders.see moreof the reviewer's review

Bought the coral one for our 3 year old and she seems to like it. Keeps her head stable when she falls asleep in the car. And plus the color is very pretty!
