While this best car seat for 3 year old is a wonderful seat for a toddler, we found it took up a space facing the rear. The seat is not only wide, but it also takes up a lot of space when you recline to the third level and the furthest. It could be great in a crew cab pickup; it can work fine. But on your regular Honda CR-V, slide the passenger seat all the way forward for it to fit.

The forward-facing car seat is safe for children up to 65 pounds (minimum 22 pounds). Because this best car seat for 3 year old is so big and roomy, wait until after the second birthday to turn the seat forward, according to the latest recommendations from child seat safety experts!
