Looking at these two pictures, do you think that both kids fit in this highback booster seat?
My son when this picture was taken he was 40lbs and 39.5" tall. Sure he can fit 5T shirts and is in the 97th percentile for height and weight. He does meet the minimum
requirements of the manufacturer.
However, if you look a little closer you will notice that the lap belt rides kind of high on him still. It's not sitting low across his lap! He probably has another 1-2 years to go before he can fit this highback booster correctly!
My daughter who is also 40lbs and 43" tall (note my kids weigh the same, one is just a couple inches taller), she is 6 year old and will turn 7 this summer. You will notice that the belt fits her a lot better than it did my son. She also meets the minimum requirements of the manufacter to use this particular HBB. Now, if you look a little closer the geometry of the seat belt fits her a lot better than it did my son. The main difference being you will see the lap belt hits her lower across her lap rather than close to her stomach...
The bottom line - when picking out a car seat for your child, please take the time to check the fit/geometry of the seat belt. This is a great example of how just because kids are the same in weight/height can fit a seat totally differently.
My son's primary seat that he rides in is a Frontier 85 - yes he is still 5pt harnessed at age 4.
