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.
