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’m happy with the mattress, price was great and quality is ok too. I appreciate the delivery right to my door, saved me a lot of hassle. The little vents in the side of the mattress are a functional addition.
