This seat is great! My daughter loves it! Was truly put to the test when we were in a wreck. She was safe and the seat didn't budge. Will be getting another when my other daughter reaches the age for it.
Both of my older two have had one and my younger two will too!! I love the versatility! You can keep the high back as long as you want or not...and if you don't like it after you take the back off... It snaps right back on!!
