Great for taller kiddos

We had the graco 4 ever carseat, but our daughter is very tall for her age. The highback booster was too small for her (wouldn't raise high enough in the back) but she wasnt ready for the booster (couldnt buckle in safely and comfortably). This carseat is a great in between for tall children. Plus our daughter says the material is more comfortable!

this carseat is easy to assemble although my husband had to push the handles on because I wasn't able to! its comfy and best of all saves us space to have 3 seats across the back of my nissan sentra. it also makes buckling easier because you can get your hand down in between!
