Car seats- all in one?

Is it worth it to buy a car seat that goes from rear facing to booster with everything in between? Is it safe to have a car seat for that long (providing there are no car accidents)? The Graco 4ever all in 1 is so highly reviewed on Target’s website. FTM with no clue how this works!! 😫
