Parkway SG Matrix Booster Car Seat

We needed 2 of these to work a "three across" in the back of our '02 Oddy. If I didn't need a narrow booster I would have gone with another booster I think. The seat is somewhat narrow and I don't see my 75 pound son  making it anywhere near 100 pounds in the hips. The arm rests also are really low which makes buckling, especially in a tight three across really hard. So while it suits its purpose (needing a narrow booster) it wasn't what I had hoped for in this highly talked about booster. The SG feature is nice if you have a low weight rider but for the great majority of kids if the sg feature is "needed" (to prevent submarining) they can/should still be harnessed anyway.
