Query: Car Seat Not User Friendly

I am disappointed with this car seat. I used it during my 35-lb grandson's five-day visit last week. I found:* The crotch strap too short. It is only 5 inches (total from the seat pan to the upper tip of the release buckle) and there is no adjustment. It requires effort to reach between the child's thighs to insert the buckle tongues into the buckle. Because it is so short, it also causes discomfort to the crotch of my grandson. The owner's manual shows the buckle rides higher near the stomach area which would have been more comfortable.* The extra seat cushion is ineffective. It is not attached to anything. The weight of the child keeps the bottom down but the side flaps tend to get tangled with the seat harness. I end up not using it.I bought this car seat based on other users' reviews. My experience keeps me from recommending this to others.
