The biggest con with the
Comfortsport is that the harness slots are very short AND you can only use certain slots in certain directions. I used one for my son and he outgrew it at 16 months
RFing (and that was PUSHING the limits of the slots) and his shoulders were over the top slots by 19 months (he is very tall). The Triumph Advance is a GREAT seat and will
RF the child to 35lbs and
FF the child until 50lbs IN the harness. My 5 y/o fit in this seat!!!!
