We moved our son to this carseat at 8 months and I thought we would miss having the infant carseat, but we love it! It is so much easier to load him in and out of the car. I have struggled with wrist tendon issues and the turning feature helps SO much. I definitely don't miss lugging around the super heavy infant carseat anymore! Installation was so much easier than I thought it would be and once Brandy S · cybex-online.com

I have owned a graco slim fit since my oldest was 2. He is almost 8 and has been in the same car seat from rear facing until 4yrs old to forward facing in harness mode and now we switched him to High Back Booster mode. And through all these years this car seat has cleaned up so well. It still looks brand new like I just pulled it out of the box. And it converts so easy between every stage of life.
