We have two for our premiee twins who came home at around 4 lbs in our Civic. The seats fit them well today at 22 pounds each. They are now 30 inches at just a year old, and I predict that given their above average height, these will last until they are two year old. I am not disappointed as I treated these as infant seats, which only last about that long. Our true infant seats in our minivan are finished, and they have barely made a year in them. The straps were easy to connect but I would suggest getting someone to help with the install.
ProsVery easy to adjust
for small babies and preemies (very low weight requirement)
ConsNeed help on install
will not work for an above average grower
Best Usessmall babies. consider this an infant chair that may make it to 24 months if you baby is likely to be above the 50%-ile in height and/or weignt.
