I love how sturdy and comfortable this seat is. I bought three in different colors for my three oldest children (ages 6, 7, and 8) and they're all very happy in them. There's great support for them and the fit is excellent, I love how adjustable they are. I own a few different booster seats in this price range from other brands that I use in our other vehicles but these are definitely my favorite. You are required to have vehicle head support behind the seats, even with the high back portion of the seat attached, so they may not work for all vehicles but I highly recommend them if they do.
