i'm so bummed that this carseat is not the quality i expected and hoped it would be. we bought this for our 14 month old son because of the rave reviews and tons of personal recommendations. while very comfy and fits tightly in the vehicle, the restraint system has a huge problem. the lap belt goes on my sons upper thighs, not his hips! if we were to get in an accident this could cause dislocation of his legs. like my husband says "it's just basic physics". i can't believe this seat is considered the *best* and i've only read one other review that mentioned this problem. nonetheless, i'm am taking it back tomorrow. we will test the marathon to see if it is a different restraint system, but if not, we will have to find something else. again though, it baffles me that no one else has mentioned this problem!!!!!
