My mom is a preschool teacher and transports a preschool student (B) to his daycare (my sister) after school. She currently has a Graco Nautilus that B rides in. The problem that she's having is that between the Tahoe sitting up so high and the high arm rests on the Nauti, B can't get into the Nauti on his own and when she trys to help him in she ends up hitting his head on the door frame or ceiling. She'd like a lower profile seat that's easier for him to get into on his own. I suggested the Evenflo Maestro after she asked me about the Cosco Highback Harness Booster. Is there anything else that I should recommend her to look at besides the Maestro?
