To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I love that I can feel safe knowing that my son can breathe with this mattress cover. My son sleeps face down..and while I absolutely love his Colgate Ecospring Diploma mattress, i love this protective and functional mattress cover that goes over the mattress too!
