Query: My son LOVES his big boy booster ...

My son is almost 3 1/2, weighs 40 lbs., and is 41 inches tall. The lights are easy for him to reach & a huge plus for nighttime driving (so much better than turning on the interior light). The seat is very soft and thicker than others in this price range. He enjoys getting to use the seatbelt and unbuckle himself. The snack/drink holders are easily accessible. He likes the armrest and it is easy for him to climb in and out. He has not fallen asleep in it yet so I cannot comment on the "bobble head". It has a good crash test rating. I can't say anything negative about this carseat; however, I do wish I would have purchased one with the harness system for up to 50 pounds ... they just seem to be more safe and secure (especially for interstate/highway travel). Otherwise, for just driving around town, you can't beat the quality or comfort of this carseat for the price.
