The forward facing harness limit for our diono radian is 65 lbs and 57 inches tall. I have never met a 4.5 year old that size. My average size 5 year old is 43 lbs and 43 inches tall. |
We have the Britax Dual Fit for our 6 year old who is 45 lbs and she fits it with a ton of room to grow. I’m not sure what price you’re looking for but it was $169 , so cheaper than most of the seats we looked at but a little more expensive than the cheapest ones. |
