Query: Not safe

I keep looking but I can not find a safe car seat cover anywhere that is warm. I wish manufacturers would make them so people who car about their child's safety will buy one. Anything that goes between the child and the carseat should not be used as it can interfere with the car seats safety, the bottom part of this goes between the child and the car seat and therefore this product should not be bought.I am still in search of a warm car seat cover that meets these standards.
