We bought this booster seat for my 2 year old son (tall for his age) because of how his feet would hang & kick the driver seat from his convertible carseat in my husband's pickup truck. My son fits the minimum requirements for height & weight, but I think the weight minimum should be higher because I can see the seat wobble a little bit because of the low weight sitting on it. The cup holders are in easy reach for him and seem more sturdy then the Evenflo convertible seat ones. Having 2 cup holders is also nice because he can put his sippy cup in one and a few of his small toys in the other. He has taken a nap in the car seat and his head didn't flop forward, it laid perfectly on the side head rest. The side head rests are a perfect width to support his head and to not block his view out the window. It is also nice that once he gets too tall for this seat that we can take the back off and still use the booster part. The arm rests can even fold up to the side of the seat back in case he wants them out of the way. Loved the fact that this booster seat came already assembled, I remember reading reviews on others saying other brands did not. I think we will buy a 2nd one once he outgrows the convertible seat in my car.
