Evenflo Generations will fit for a long time
We purchased the evenflo generations carseat for my son when the convertible car seat that had been used by his older brothers started getting a bit old for my comfort level. I really liked that the car seat would be able to be used for a long time as a five point harness and then even longer still as a booster seat. The waterproof "piddle pad" has been a lifesaver a couple of times when a diaper leaked and is so easy to take out just that part and wash it rather than removing the entire cover. The pillow on the other hand did not make much sense and seemed to push my son's head forward at an awkward angle so we don't use that since it seemed so uncomfortable. The cup holder would not stay on and within two months one of the arms started repeatedly falling off. We still use the seat and put the arm back on once a week or so. The carseat was easy to install and looks very nice even though it has been used for quite awhile now.
