Query: NOT SAFE FOR INFANTS WHO SIT UPRIGHT

We, too, had an accident with this product. Just today, my 7 month old daughter (21 pounds) flipped the seat forward and landed on her forehead on our hardwood floor. Big egg on forehead above eye. If your infant can sit upright and leans forward -- and is on the heavier side -- it's going to flip.Any product that causes an accident does not deserve more than one star no matter what.
