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.
My students love them and use them to sit on or put their chromebooks on. The only thing I don't like is one color (I think orange) does not have the zipper like the other colors. Why is that? I saw that in other reviews also. Overall works well in the classroom. I love that we can wipe and go. Great for little ones.
