My son is 4 1/2 and about 50lbs. Hes kinda big for his age. He's been in a Chicco NextFit since about a year old and I've noticed some of the plastic in the bottom that keeps his straps in have started so change color from bending. I'm looking for a carseat that can hold him in a harness for as long as possible and most of the car seats I'm finding all cap out at 65lbs.
The highest weight limits I've found are Maxi Cosi 85, Graco Nautilus 80, and Britax Pinnacle Click-Tight 90. Does anyone have one of these carseats? And how do you/your child like it??
