The Grows4Me fit all of our models well — from 3 days to 9 years old. There is but a smattering of car seats on the market today that could make such a claim! So families who would like to get that full 10 years of use from one car seat could conceivably do so with this seat. The primary difference between this seat and the Graco 4Ever is the lower anchors — this seat has the still functional, but harder to use standard j-hook style, while the 4Ever has premium push button lower anchors. Families who know they’ll primarily be installing this seat with a vehicle seat belt or who don’t mind the standard lower anchors have a great option in the Grows4Me.
