any thoughts on Graco Cargo Booster Car seat?

I've heard some say it is too narrow, but that would actually be a good thing for me. Do you think it is narrow compared with other seats? What else do you think about this seat? I am thinking of getting model 8D02SYC, which can be viewed at www.Gracobaby.com. Which model do you have?
This is 5pt

I could see where this seat may be narrow for a larger baby and it does in fact convert to a high back booster by removing the 5pt harness. I looks comfortable and I like the little pillows by the child head, very handy if child falls asleep. I do not personally know anyone who has purchased one though. As with all carseats, I suggest you try it in your car before you buy it. Some car seat have indentations or a tilted bottom that make the safety seat difficult to install properly.
