I first bought this seat for my son at 1 years old when he outgrown the infant seat. My son is still setting in this seat at 4 years old and 38 pounds. It's heavy but I love the cup holder for his sippy cup, the five point buckle harness to keep him safe, it's so easy to take apart to clean then put back together, and that it is easy to install in the car. It is a little difficult to get out of the car though but I like that because that means the seat is very secure and won't be sliding around in the backseat. I love that I don't have to buy another car seat because you can take parts away and it grows with the child. It's a great buy on the cost also. I highly recommend. I will be putting my second child in a car seat just like this one when he's old enough.
