That recaro is one of the most adjustable on the market. They have speakers in the head rest and a optional footrest that you carn buy. Speaker are great for the long drive so you don't have to listen to thier movies. The footrest help keep their feet off the back of your seats. Look at our maxima's seats and they corners are much darker bc of my sons feet.
Most importantly
if they can build safe race seats I would think that they could build a safe infant seat. That is why I will buying one in the comming months when my son is too tall for his current seat.
