Best convertible booster I've ever seen

I am amazed by all of the features this seat has to offer. I bought it for my 4 year old son who just made 30 lbs. although for every day he will continue to use a 5-pt. harness car seat. I needed an un-complicated car seat (nothing to install, easy to get in/out) for when his grandparents keep him and take him to preschool. I am a car seat fanatic and refused to put him in something unsafe for his size and this car seat is literally a perfect fit.

There are so many ways to adjust the head, back and bottom booster it makes my head spin! It certainly leaves no excuse for a child to be restrained incorrectly. I was also surprised to see the added features of dual lights and cupholders, something I wasn't looking for initially, but are nice extras.

This will also be a great backless booster for our 6 year old when needed, as the handles do not get in the way of buckling.
